Does sports club participation contribute to physical activity among children and adolescents? A comparison across six European countries

Perceived coaches' health promotion activity, maintenance of participation in sports, and lifestyle habits among emerging adults: a four-year follow-up study

OBJECTIVES

This study focused on how adolescents' perceptions of coaches' health promotion activity predict maintained participation and dropout in organized sports in emerging adulthood. In addition, differences in lifestyle habits between maintainers, dropouts, and nonparticipants in organized sports were explored.

MATERIALS AND METHODS

Overall, 616 adolescents reported organized sports participation in the Finnish Health Promoting Sports Club (FHPSC) study at ages 15 and 19. Of these, 323 reported coach's health promotion activity on health topics at the age of 15. An index of a coach's general health promotion activity was formed. At age 19, all study participants reported their lifestyle habits.

RESULTS

Among males, those who had perceived coaches' general health promotion activity as frequent were more likely to be maintainers than dropouts (48.6% vs. 20.0%) (p = .002). Among females, there was no significant difference (32.0% vs. 28.4%). Logistic regression analysis adjusted for gender showed that perceiving coach's general health promotion activity as frequent increased the odds of being a maintainer rather than a dropout. Moreover, maintainers had higher odds of having healthy lifestyle habits when compared to nonparticipants (related to physical activity; sleep; fruit and vegetable consumption; and cigarette use) or dropouts (related to physical activity; and cigarette use). In addition, dropouts had higher odds of having healthy lifestyle habits than nonparticipants (related to sleep; and cigarette use).

CONCLUSIONS

Perceiving coaches' health promotion activity as frequent was related to maintained participation in organized sports among males. Maintainers were more likely to have more healthy lifestyle habits than nonparticipants and dropouts. There is a need to invest in coaches' health promotion activity when it is infrequent. A more detailed understanding is needed of coaches' health promotion activity that supports both maintained participation in sports, especially among females, and healthy lifestyle habits in emerging adulthood.

Individual and day-to-day differences in domain-specific physical activity of 10- to 11-year-old children in Denmark-Measured using GPS and accelerometry

OBJECTIVE

Physical activity (PA) and the achievement of 60 min of moderate-to-physical-activity daily is declining in school-aged-children, and effective strategies to increase PA is needed. We aimed to examine the individual and day-to-day distribution of PA on schooldays among children aged 10-11 in 4 domains-school, home, transport, and other.

METHODS

Data were collected from August to September 2020 using accelerometer and GPS data to measure daily PA-levels and to locate in which domain PA occurs. Daily PA-levels were assessed in each domain, and analyses of the individual and day-to-day differences in PA-levels were calculated.

RESULTS

The school domain contributed the most to children's daily MVPA with 47% of average MVPA, followed by the home domain with 26% of daily average MVPA, the other domain with 19% of daily average MVPA and the transport domain with 8% of daily average MVPA. Our results showed individual differences in where PA occurs, day-to-day differences in total MVPA and day-to-day differences in the MVPA-levels across domains.

CONCLUSIONS

The school domain contributed the most to children's MVPA-levels followed by the domains of home, other, and transport. Our study indicated that PA-levels and the distribution of PA across domains differ from day-to-day. Future interventions should target more than one domain to accommodate these individual- and day-to-day differences in the goal of increasing PA-levels and to reduce the decline in PA seen from childhood to adolescence.

Identifying latent classes of physical activity profiles over time among adolescents in Ontario, Canada

BACKGROUND

Physical activity behaviours are known to be highly correlated. Adolescents who participate in one type of physical activity (e.g., physical education) have a greater likelihood of participating in other physical activities (e.g., organized sports); however, little research has examined participation rates in various physical activity behaviours concurrently. This study identified longitudinal physical activity profiles among secondary school aged youth in Ontario, Canada.

METHODS

We used data from the COMPASS Study, a school-based prospective cohort study of adolescents in Canada. Using a repeated measures latent class analysis, Ontario students who participated in grade 9 PE in 2015-16 were analysed through to 2018-19 (n = 1,917). Latent classes were defined by: PE participation, guideline adherence (≥ 60 min/day of moderate to vigorous activity over the last 7 days), and sport participation (varsity, community, and/or intramural). Multinomial logistic regression models were used to examine associations between latent class membership and student characteristics.

RESULTS

Three distinct latent classes were identified for females and four were identified for males. These classes were: (1) Guidelines (high probability of guideline adherence; females: 44%; males: 16%), (2) PE & Sports (high probability of PE and sport participation; females: 33%; males: 43%), (3) Guidelines & Sports (high probability of guideline adherence and sport participation; females: 23%; males: 23%;), and (4) Inactive (low probability of all physical activity indicators; males: 18%). Strength training, sleep, and English grade were associated with class membership among females. Ethno-racial identity, weekly spending money, strength training, and English and math grades were associated with class membership among males.

CONCLUSIONS

Findings suggest that latent physical activity profiles differ by sex. Guideline adherence was the most common class among females, indicating high levels of independent physical activity, whereas PE & Sport participation was the most common class among males, indicating greater tendency towards organized activities. Additionally, a substantial number of male students were not engaging in any physical activity. Participation in both PE and sports did not necessarily lead to meeting physical activity guidelines, highlighting that these activities alone may not be providing sufficient levels of physical activity that align with current recommendations for Canadian youth.

Adherence to the WHO recommendation of three weekly days of vigorous intensity activities in children: an accelerometry study of vigorous physical activity bouts

Background

The World Health Organization (WHO) recommends that children and adolescents incorporate vigorous intensity activities (VIAs) at least three days a week. This recommendation has not been sufficiently studied using objective methods, such as accelerometry. Physical education classes and extracurricular sports activities are optimal opportunities for compliance with this recommendation.

Objective

To identify VIAs through bouts of vigorous physical activity (VPA-Bouts) evaluated with accelerometry and, with this, to know the compliance with the recommendation on VIAs.

Methods

A cross-sectional study of the habitual physical activity of 353 children (8-9 years old) was carried out using accelerometry and participation in organized extracurricular sports activities was asked through a questionnaire. School days with and without physical education class, weekends, and the average weekly day were identified, as well as school time and out-of-school time. A VPA-Bout was defined as an interval of at least 60 minutes with a proportion of VPA of at least 16.7% in boys and 12.5% in girls (10.0 and 7.5 minutes/hour of VPA, respectively).

Results

The average daily time in organized extracurricular sports activities declared by questionnaire and the average daily duration of the VPA-Bouts evaluated with accelerometers in the extracurricular period was 21.3 (SD 19.8) and 23.9 (SD 31.2) minutes, respectively, in boys, whereas, in girls it was 20.2 (SD 17.4) and 11.0 (SD 16.9) minutes, respectively. In school time including a physical education class, there was a higher proportion of VPA-Bouts than without these classes (with: 28.6%, without: 2.1%, p < 0.001). Children who reported at least three weekly hours of organized extracurricular sports activities accumulated a higher proportion of school afternoons with VPA-Bouts than those with fewer weekly hours of this type of activities (≥3 hours/week: 27.5%, <3 hours/week: 9.3%, p < 0.001). On the weekend, boys who reported at least three weekly hours of organized extracurricular sports activities performed more VPA-Bouts than those participating in less weekly hours, while in girls no significant differences were observed (weekend; boys, ≥3 hours/week: 26.0%, <3 hours/week: 9.0%, p < 0.001; girls: 8.3%, 8.0%, p = 0.917). Compliance with the recommendation to incorporate VIAs at least three days a week was 23.8%. Children who reported at least three weekly hours of extracurricular sports activities achieved higher compliance than those who reported fewer extracurricular activities (≥3 hours/week: 35.1%, <3 hours/week: 12.7%, p < 0.001). Additionally, boys showed higher compliance rates than girls (boys: 32.9%, girls: 15.3%, p < 0.001).

Conclusion

One in every four children met the WHO recommendation to incorporate VIAs at least three days a week, as evaluated by accelerometry. Physical education classes and extracurricular organized sports activities contributed to compliance with this recommendation.

Implementation of the GAA 'healthy clubs project' in Ireland: a qualitative study using the Consolidated Framework for Implementation Research

The sports clubs' role in promoting health has been acknowledged by policy makers and researchers, but there is little evidence on how sports clubs implement health-related interventions. The present article investigates the Gaelic Athletic Association Healthy Club Project (HCP) implementation process (mechanisms, barriers, leverages) over a 10-year timeframe. A case study design helped to produce and compare a data synthesis for five clubs involved since 2013. A qualitative iterative data collection, including document analysis was conducted through 20 focus groups with Healthy Club Officers, coaches, participants and members. The Consolidated Framework for Implementation Research was used in the deductive analysis process, conducted by the first author. Results have shown the success of the HCP in placing health promotion on the agenda of sports clubs leading to informal policy for health promotion, even if activities and recognition are directed toward and coming from the community. This study also underlines the virtuous cycle of the settings-based approach in enhancing membership and volunteer recognition through health promotion actions, and the importance of social good and corporate social activities for sports clubs. Nevertheless, the HCP still relies on limited human resources, is not recognized by competitive oriented adult playing members. and acknowledged as a resource by some coaches, limiting its rootedness in the core business of sports clubs. Future research should empower the HCP community to focus on organizational changes and develop outcomes for individuals, for the club as a whole as well as for the local community.

The status of active after-school clubs among primary school children in England (UK) after the COVD-19 lockdowns: implications for policy and practice

BACKGROUND

Children's physical activity in England is more dependent on active clubs after the COVID-19 pandemic. However, it is unclear how the COVID-19 pandemic and related cost-of-living crisis have impacted on active club participation, costs and provision. This mixed-methods natural experiment explored school-based and community-based active clubs after lockdowns, using a unique combination of data sources to highlight implications for policy and practice post-COVID-19.

METHODS

Cross-sectional questionnaire data on school and community active clubs were collected from 10-11-year-old children pre-COVID-19 in 2017-18 (N = 1,296; 50 schools), in 2021 (N = 393; 23 schools), and 2022 (N = 463; 27 schools). Club participation and attendance frequency were modelled using logistic and Poisson mixed effects models, adjusted for child age, gender and household education. In 2021 and 2022, parents reported expenditure on community-based clubs and schools provided data on school-based club provision, with data summarised descriptively. Qualitative data were collected in 2021 and 2022, with one-to-one interviews with school staff (N = 18) and parents (N = 43), and twelve child focus groups (N = 92), and analysed using the framework method.

RESULTS

School-based active club participation was higher in 2022 compared to pre-pandemic (50% /43%), while community-based club participation was lower (74%/80%). Children attended 0.3 fewer clubs per week. Those from lower education households were less likely to participate in both types of active clubs, and girls less likely to attend community clubs. In 2022, the median cost of community and school club sessions were £6.67 and £3.88 respectively, with 52% of school-based clubs free to parents. Schools offered an average of 3.4 active clubs per week for 10-11-year-olds in 2022, with 34% partly/wholly subsidised. Qualitative analysis highlighted the impact of the cost-of-living crisis and COVID-19 pandemic on family resources, encouraging a shift to more affordable and convenient school-based active clubs, which negatively impacted the community-based active club environment. However, many schools struggled to meet this increased demand.

CONCLUSIONS

Findings emphasise the importance for policymakers to support schools to meet increased demand for clubs and community clubs to increase affordable and convenient physical activity opportunities. Targeted support is needed to prevent socioeconomic and gender inequalities.

Health promoting sports federations: theoretical foundations and guidelines

Background

Researchers and policy-makers have highlighted that the potential for organized sports to promote health has been underexploited. Sports clubs have limited capacity to promote health due to their voluntary nature and have called for support from their national sports federations. The present article provides guidelines, based on the theoretical principles of health promoting sports clubs and an analysis of practical tools and proven strategies, to support national sports federations to invest in health promotion (HP).

Methods

A qualitative iterative study was undertaken, based on five 2-h meetings of a group of 15 international researchers in HP in sports clubs. Notes and minutes from meetings, as well as shared outputs were analyzed based on the health promoting sports club framework.

Results

Guidelines developed for national sports federations to promote health includes a definition of a health promoting sports federation (HPSF), a description of how the settings-based approach to HP adapts to national sports federations, as well as practical applications of health promoting sports club's intervention strategies. The analysis of existing tools also demonstrated that most tools are centered on a single dimension of health (social, mental, physical, spiritual or community), and often on a specific health topic. Furthermore, they do not cover HP as a continuous long-lasting process, but are generally short-term programs. The HPSF clarifies theoretical concepts, their practical implementation via case studies and outlines intervention components and tools useful for sports federations in their implementation of HP.

Conclusion

The guidelines developed in this study are intended to facilitate national sports federations to acknowledge/understand, reinforce/underpin and foster current and further investment in HP.

Promotion of health-enhancing physical activity in the sport sector: a study among representatives of 536 sports organisations from 36 European countries

BACKGROUND

It is a common belief that most sports clubs and organisations are primarily focused on elite sports while placing less emphasis on the promotion of health-enhancing physical activity (HEPA). However, there is a lack of evidence on this topic in the scientific literature. Therefore, the aim of this study was to determine the level and correlates of the commitment of sports organisations in Europe to HEPA promotion.

METHODS

Representatives of 536 sports organisations from 36 European countries responded to our survey. A multiple regression analysis was conducted with the commitment of sports organisation to HEPA promotion (0 ["not at all"] - 10 ["most highly"]) as the outcome variable and organisation type ("national sport association" reference group [ref], "European sports federation", "national umbrella sports organisation", "national Olympic committee", "national sport-for-all organisation"), headquarters in a European Union member state ("no" [ref], "yes"), region of Europe ("Western" [ref], "Central and Eastern", "Northern", "Southern"), commitment to elite sports ("low" [ref], "medium", "high"), and awareness of Sports Club for Health (SCforH) guidelines ("no" [ref], "yes") as explanatory variables.

RESULTS

Approximately 75.2% (95% confidence interval [CI]: 71.5, 78.8) of sports organisations were highly committed to elite sports. Only 28.2% (95% CI: 24.4, 32.0) of sports organisations reported a high commitment to HEPA promotion. A higher commitment to HEPA promotion was associated with the national Olympic committees (β = 1.48 [95% CI: 0.41, 2.55], p = 0.007), national sport-for-all organisations (β = 1.68 [95% CI: 0.74, 2.62], p < 0.001), location in Central and Eastern Europe (β = 0.56 [95% CI: 0.01, 1.12], p = 0.047), and awareness of SCforH guidelines (β = 0.86 [95% CI: 0.35, 1.37], p < 0.001).

CONCLUSION

From our findings, it seems that most sports organisations are primarily focused on elite sports. Coordinated actions at the European Union and national levels are needed to improve the promotion of HEPA through sports organisations. In this endeavour, it may be useful to consider national Olympic committees, national sport-for-all organisations, and relevant sports organisations in Central and Eastern Europe as role models and to raise the awareness of SCforH guidelines.

Handling Public's Well-being during the COVID-19 Crisis: An Empirical Study with Municipalities' Representatives in Sweden

BACKGROUND

COVID-19 had a significant impact on the public's health and well-being due to infections and restrictions imposed during the crisis. Recreational activities are important for the public's well-being, however comes in second in relation to the public's safety from the COVID-19 virus. In Sweden, a country with a decentralized public health and welfare system relied on less stringent approaches for handling the crisis. The limited restrictions of Sweden allowed the recreational activities to take place despite the pandemic, which could be attributed to considerations for the public's well-being.

OBJECTIVE

The objective of this study is to investigate municipal approaches for handling and supporting recreational activities during the COVID-19 crisis.

METHODS

We conducted an empirical study (qualitative and quantitative), using an online survey for data collection, with 23 participants. They were representatives holding mostly managerial roles, from 18 distinct municipalities (of 18 counties). A thematic analysis was conducted to analyze open-ended responses, and descriptive statistics was used as a method to summarize the close-ended responses.

RESULTS

In this study, we report on the status of municipalities during the COVID-19 pandemic. The highlighted results show a significant impact on the municipalities as a result of COVID-19, where 78.3% of participants state significant changes due to the pandemic. 88.9% indicate efforts and approaches for supporting recreational activities during COVID-19. Following national guidelines for public's health and safety is indicated by 78.3%. Information and Communications Technologies (ICTs) were considered significant for dealing with COVID-19 as per 87% of participants. Our qualitative results further show details of public's health and safety considerations, efforts to support recreational activities particularly for youth, and ICTs role and requirements. Challenges relating to the usability of ICTs were also highlighted.

CONCLUSIONS

Despite the critique of Sweden's lenient strategy of handling the COVID-19 crisis, our results show significant considerations for both the public's safety and well-being by the municipalities (additionally on a regional and local levels) in this study. Trusting the public with safety guidelines in addition to efforts for publics' safety, supporting public's well-being with approaches for maintaining recreational activities, and giving special care to youth, was the Swedish approach to handling the crisis. Despite having technological solutions in place, challenges using digital solutions and requirements for future development are noted.

Secular trends in 20 m shuttle run test performance of 14- to 15-year-old adolescents from 1995 to 2020

PURPOSE

To investigate whether Finnish adolescents' cardiorespiratory fitness measured using the 20 m shuttle run test (20mSRT) changed between 1995 and 2020 and to examine between-group variation in the five datasets during the past 25 years.

METHODS

Data on five cohorts were collected in 1995 (n = 498), 1998 (n = 796), 2003 (n = 2383), 2010 (n = 1383), and 2020 (n = 719). The 20mSRT was administered, following the exact same protocol, to all cohorts. A general linear contrast model was used to examine cohort differences in the 20mSRT scores. Variation across cohorts was tested using chi-square-based between-group tests.

RESULTS

Girls' 20mSRT scores decreased from 1995 to 2010 and remained stable from 2010 to 2020. Boys' 20mSRT scores decreased continuously from 1995 to 2020. In addition, the variation in girls' 20mSRT scores was larger in the 2020 than 2003 cohort, indicating the growth of SRT differences between individuals in 2020 cohort compared to 2003 cohort. Similarly, boys' scores showed greater variation, especially in the 2010 and 2020 cohorts than in the 1998 cohort.

CONCLUSION

The results of this study showed an overall decline in the cardiorespiratory fitness performance measured by 20mSRT of Finnish adolescents. Boys' scores decreased continuously from 1995 to 2020, whereas girls' scores remained stable after 2010. Examination of the variation in scores further revealed that the gap in scores between the adolescents with the highest and lowest scores increased over time.

Effect of Elite Sport on Physical Activity Practice in the General Population: A Systematic Review

BACKGROUND

Our study investigated the effect of elite sport on physical activity (PA) practice in the general population.

METHODS

Structured Boolean searches were conducted across 5 electronic databases (PubMed, JSTOR, Web of Science, SPORTDiscus, and PsycInfo) from January 2000 to August 2021. Peer-reviewed studies in English were included if the effects of hosting elite sport events, elite sport success, and elite sport role modeling on PA/sport practice in the general population were measured.

RESULTS

We identified 12,563 articles and included 36 articles. Most studies investigated the effect of hosting elite sport events (n = 27), followed by elite sport success (n = 16) and elite sport role modeling (n = 3). Most studies did not observe a positive effect of hosting elite sport events, elite sport success, or elite sport role modeling on PA/sport practice in the general population. No evidence of a lagged effect of elite sport was observed. No evidence of elite sport effects was observed according to age range and geographical scale.

CONCLUSION

There is no evidence supporting the effect of elite sport in increasing PA or sport participation in the general population. Decision makers and policymakers should be aware of this and invest in strategies such as those recommended by the World Health Organization.

University students' overall and domain-specific physical activity during COVID-19: A cross-sectional study in seven ASEAN countries

This research investigated the overall and domain-specific physical activity (PA) of university students in the coronavirus disease 2019 (COVID-19) pandemic. A cross-sectional study was applied to socioeconomic (SE) and PA online data collected from 15,366 students across 17 universities in seven Association of Southeast Asian Nations (ASEAN) countries. Statistical analyses using logistic regressions established SE-PA relationships. Over half (60.3%) of ASEAN university students met age-span specific PA guidelines. Students participated in recreational PA the most, followed by study-related activities and 44.1% of students engaged in >8 hrs/day of sedentary time (ST). Compared to students with a normal body mass index (BMI), students who were underweight (UW), overweight (OW), and obese (OB) respectively, had a 14% (UW odds ratio (OR) = 1.14, p = 0.005), 25% (OW OR = 1.25, p < 0.001), and 24% (OB OR = 1.24, p = 0.005) greater probability of meeting PA guidelines. Those who engaged in active transport and belonged to a sports club (SC) had 42% (SC OR = 0.58, p < 0.001, for both) less probability of meeting the PA guidelines, compared with those who travelled inactively and did not belong to a sports club, respectively. Students who participated in 4-6 sport or exercise activities had ten times more likelihood of meeting PA guidelines (OR = 10.15, p < 0.001), compared with those who did not play any sport or do any exercise. Students who spent >8 hrs/day of ST had 32% (ST OR = 0.68, p < 0.001) less probability of meeting PA guidelines, compared with those who spent <3 hrs of ST. These data showed that over half of ASEAN university students achieved PA guidelines and were highly sedentary during the COVID-19 pandemic. Recreational and study-related activities were important for students to maintain sufficient PA and should be actively promoted within the restrictions imposed during periods of the COVID-19 pandemic lockdowns.

Association between sports participation and overall health in children and adolescents

Emerging evidence revealed that participating in sports may have benefits for health, but the association between sports participation and self-rated overall health has not been clearly established in children and adolescents. The present study aimed to examine the cross-sectional relationships between sports participation and self-rated overall health. A national sample of 42,777 (mean age = 9.4 ± 5.2, 48.3% girls) United States children and adolescents completed self-administered questionnaires and were included in the final analysis. The crude and adjusted odds ratio (ORs) and 95% CI were used to analyze the association between sports participation and self-rated overall health. Results indicated that children and adolescents participated in sports were more likely to report better overall health (OR = 1.92, 95%CI: 1.83, 2.02) compared to those not participating in sports. This study found that sport participation was positively associated with self-rated overall health in children and adolescents. This study offers evidence concerning adolescents' health literacy promotion.

Organized Youth Sports Trajectories and Adult Health Outcomes: The Young Finns Study

INTRODUCTION

This study identified the trajectories of organized youth sports over 9 years in youths aged 9-18 years and examined whether the trajectories predicted physical activity, sedentary behavior, and obesity in midlife.

METHODS

Self-reported organized youth sports trajectories were identified for participants between 1980 and 1989 (N=3,474). Accelerometer-derived physical activity was quantified for participants (n=1,349) in 2018-2020. Sociodemographic, physical activity, and TV viewing data were collected through questionnaires either at baselines or follow-up. Adult BMI was calculated to clarify obesity. Associations of organized youth sports trajectories with adult physical activity, sedentary behavior, and obesity were evaluated using mixture models, which were stratified by sex and conducted in 2022.

RESULTS

Three organized youth sports trajectories were identified for boys and girls (sustained high-sports participation, 12.0%/7.5%; sustained moderate-sports participation, 14.0%/13.3%; and low-sports/nonparticipation, 74.0%/79.2%). Boys sustaining both moderate- and high-sports participation had higher levels of adult self-reported physical activity (β=0.59, p=0.007; β=0.69, p<0.001) than low-sports/nonparticipating boys. Girls sustaining both moderate- and high-sports participation accumulated more total physical activity (β=113.4, p=0.009; β=144.3, p=0.002), moderate-to-vigorous physical activity (β=7.86, p=0.016; β=14.01, p<0.001), step counts (β=1,020, p=0.003; β=1,045, p=0.005), and self-reported physical activity (β=0.79, p<0001; β=0.63, p=0.003) in midlife than their low-sports/nonparticipating counterparts. Girls sustaining moderate-sports participation accumulated more light-intensity physical activity (β=19.79, p=0.012) and less sedentary time (β= -27.65, p=0.002), and those sustaining high-sports participation had lower obesity prevalence (OR=0.41, p=0.009) 40 years later than low-sports/nonparticipating girls.

CONCLUSIONS

Sustained participation in organized youth sports is independently predictive of physical activity patterns, sedentary time, and obesity in midlife, especially in girls, thus contributing to the development of a healthy and active lifestyle across the life course.

Does it fit better? Measures of physical activity among adolescents in relation to health indicators

BACKGROUND

Measuring physical activity (PA) is one of the pillars of successful health promotion; however, we struggle to find a tool enabling the identification of risk groups. The current standard approach of assessing moderate-to-vigorous physical activity (MVPA) every day does this inadequately. The aim of this study is to explore whether three other indicators of adolescents' PA can identify such risk groups in a better way.

METHODS

We used data on 888 11- to 15-year-old adolescents (mean age = 13.5, 56% boys) from the Health Behaviour in School-aged Children study conducted in 2018 in Slovakia. Sufficient PA was indicated by the following four indicators: (i) MVPA every day, (ii) MVPA 5-7 days a week, (iii) engagement in organized sports (team or individual) and (iv) combining MVPA 5-7 days a week and engagement in organized sports. We used binary logistic regression analysis to assess the association of various indicators of adolescents' PA with body composition, cardiovascular fitness and self-rated health (SRH), considering age and gender.

RESULTS

Being active based on various indicators was associated with better health outcomes, with the strongest associations for the indicator combining MVPA 5-7 days a week and engagement in organized sports. The only exceptions were the non-significant associations of active adolescents (being active 5-7 days per week or engaged in organized sports) with cardiovascular fitness and SRH.

CONCLUSIONS

Measuring PA using an indicator that combines MVPA 5-7 days a week and engagement in organized sports is the most valid using three health indicators as criteria.

Psychosocial aspects of sports medicine in pediatric athletes: Current concepts in the 21st century

Behavioral aspects of organized sports activity for pediatric athletes are considered in a world consumed with winning at all costs. In the first part of this treatise, we deal with a number of themes faced by our children in their sports play. These concepts include the lure of sports, sports attrition, the mental health of pediatric athletes (i.e., effects of stress, anxiety, depression, suicide in athletes, ADHD and stimulants, coping with injuries, drug use, and eating disorders), violence in sports (i.e., concepts of the abused athlete including sexual abuse), dealing with supervisors (i.e., coaches, parents), peers, the talented athlete, early sports specialization and sports clubs. In the second part of this discussion, we cover ergolytic agents consumed by young athletes in attempts to win at all costs. Sports doping agents covered include anabolic steroids (anabolic-androgenic steroids or AAS), androstenedione, dehydroepiandrostenedione (DHEA), human growth hormone (hGH; also its human recombinant homologue: rhGH), clenbuterol, creatine, gamma hydroxybutyrate (GHB), amphetamines, caffeine and ephedrine. Also considered are blood doping that includes erythropoietin (EPO) and concepts of gene doping. In the last section of this discussion, we look at disabled pediatric athletes that include such concepts as athletes with spinal cord injuries (SCIs), myelomeningocele, cerebral palsy, wheelchair athletes, and amputee athletes; also covered are pediatric athletes with visual impairment, deafness, and those with intellectual disability including Down syndrome. In addition, concepts of autonomic dysreflexia, boosting and atlantoaxial instability are emphasized. We conclude that clinicians and society should protect our precious pediatric athletes who face many challenges in their involvement with organized sports in a world obsessed with winning. There is much we can do to help our young athletes find benefit from sports play while avoiding or blunting negative consequences of organized sport activities.

Time Trends of Step-Determined Physical Activity Among Adolescents With Different Activity Levels in Czech Republic

BACKGROUND

This study aimed to present step-determined physical activity trends in adolescents with different activity levels over a period of 10 years.

METHODS

Pedometers were used to monitor weekly physical activity in 1855 boys and 2648 girls aged 15-19 years recruited from 155 schools in the Czech Republic between 2009 and 2018. Trends for average steps/day and percent of accumulating various levels of steps/day (<10,000, 10,000-13,000, and >13,000 steps/d) were analyzed by sex.

RESULTS

There was a statistically significant decrease in average steps/day between 2009-2010 and 2017-2018 in boys from 12,355 (3936) steps/d to 10,054 (3730) steps/d and girls from 11,501 (3278) steps/d to 10,216 (3288) steps/d. The percent accumulating <10,000 steps/d increased by 21% in boys and 12% in girls. The percent achieving >13,000 steps/d decreased by 17% in boys and 10% in girls.

CONCLUSIONS

Objectively collected evidence indicates an overall decrease in Czech adolescents' steps/day over a 10-year period concurrent with an increase in the percent of boys and girls accumulating <10,000 steps/d. These trends are concerning as they portend a decline in physical activity as adolescents transition to adulthood and continue to age, which also may have major health implications.

Development of the health promoting sports club-national audit tool

Background

Sports clubs have requested support from national governing authorities to invest in health promotion (HP), by developing policies, guidelines and dedicated funding. This article outlines the development of a national audit tool to review policies development and implementation to support HP in sports clubs.

Methods

A five-step process was undertaken by an international project team: (i) a rapid literature review to identify items assessing policies in physical activity, HP and sports, (ii) a thematic analysis to categorize items, (iii) a Delphi method to analyze item relevance, country specificity, reformulation, validation and organization, (iv) face validity through an online survey and in-depth interviews with expert representatives on physical activity and sports and (v) audit tool finalization though project team consensus.

Results

Eight sources were reviewed with 269 items identified. Items were coded into 25 categories with 3 broad themes: policies, actors and settings-based approach. The Delphi study extracted and refined 50 items and categorized them into 10 sections. After revisions from 22 surveys and 8 interviews, consensus was reached by the international project team on 41 items categorized into 11 sections: Role of ministry or department; Policies; Communication; Implementation and Dissemination; Evaluation and Measurement methods; Sub-national-level policies; Funding and Coordination; Participative approach; Actors and Stakeholders; National sporting events; Case studies and Implicated stakeholders.

Conclusion

To progress HP in the sports club context it is necessary to understand existing national-level policies. This national audit tool will aid in monitoring and assessing national policies for health promoting sports clubs.

Physical Activity Policies for Children and Adolescents in Brazil: Analysis for the Report Card Brazil on Physical Activity for Children and Adolescents

The aim of this study was to investigate physical activity (PA) policies in Brazil through current actions/programs to promote PA for children and adolescents. All 23 official websites of federal government agencies in Brazil [eighteen ministries, two secretariats (linked to ministries) and three ministry equivalent agencies] were visited. All programs/actions were analyzed according to indicators of the Global Matrix project from the Active Healthy Kids Global Alliance (AHKGA) and the Health Enhancing PA Policy Audit Tool, version 2, recommended by the World Health Organization. Furthermore, we used the analysis of "Strengths, Weaknesses, Opportunities and Threats" (SWOT) for the policies. Seventeen programs/actions included the promotion of PA for children and adolescents in Brazil, however, none of them had this as their main objective, and none were planned as a public policy action aimed at the promotion of PA. The overall score of the assessment instrument was 37 (out of a total of 100), which classifies Brazil as having a D+ grade according to AHKGA criteria. Brazil needs to define PA as a state policy so that the actions identified in this study can have positive effects on children and adolescents.

Sports participation and preterm birth: a nationwide birth cohort in Japan

BACKGROUND

Children born preterm may be less physically active than children born term because of neurocognitive problems, reduced lung function, and poor physical fitness. We evaluated sports participation of children and adolescents who had been born preterm (<37 weeks) and early term (37-38 weeks) in 2001.

METHODS

Data from a nationwide longitudinal survey (n = 47,015, including 2375 children born preterm) were analyzed. As indicators of sports participation, we used responses to questions about participation in sports clubs at 7 and 10 years old and in extracurricular school sports at 15 years old.

RESULTS

Children born very preterm (25-31 weeks) and moderately to late preterm (32-36 weeks) were less likely to participate in sports clubs at 7, 10, and 15 years old than children born full term (39-41 weeks). Compared with children born full term, the adjusted risk ratios for participation in extracurricular school sports at 15 years old were 0.86 (95% confidence interval: 0.75-0.98) for children born very preterm, 0.92 (0.88-0.97) for children born moderately to late preterm, and 1.00 (0.98-1.02) for children born early term.

CONCLUSIONS

Our findings suggest that preterm birth is associated with less participation in organized sports during childhood and adolescence than full-term birth.

IMPACT

Research investigating associations between preterm birth and physical activity among children born in the 2000s is limited. This study shows that preterm birth was associated with less participation in organized sports during childhood and adolescence than full-term birth, especially in boys, and the participation in organized sports of children born preterm decreased as gestation shortened. During childhood, boys born early term were also less likely to participate in organized sports than boys born full term, suggesting a continuum with preterm births. These findings offer important additional insights into the limited evidence available for predicting future health outcomes for preterm infants.

Changes in the continuous leaping performance of Finnish adolescents between 1979 and 2020

The aims of this secular trend design study were: 1) to investigate whether the continuous leaping performance of Finnish adolescents (mean age 14.99 ± .61 years) changed between 6 data sets collected between 1979 and 2020, and 2) to analyse if variation in leaping performance increased from 1979 to 2020. The data for this secular trend study of 6 cohorts were collected in 1979 (n = 599), 1995 (n = 498), 1998 (n = 796), 2003 (n = 2383), 2010 (n = 1383), and 2020 (n = 719). All cohorts performed the 5-leaps test, following the same protocol. Between-cohort differences in scores were analysed using a General Linear Contrast Model. Between-cohort differences in variance were tested using Chi-square-based between-group tests. Sex, age, and BMI were used as covariates in the secular trend analyses. Continuous leaping performance demonstrated a decreasing trend in both girls and boys. Specifically, girls' scores were stable between 1979 and 1995, decreased from 1995 to 2010 and remained stable thereafter. Boys leaping performance improved from 1979 to 1995, was stable until 2003, and had declined by 2020. Within-group variation in continuous leaping was greater in girls and boys during the first decades of the 21st century than previously.

Development of Cardiorespiratory Fitness in Children in the Transition From Kindergarten to Basic School According to Participation in Organized Sports

Purpose: This study examined the development of cardiorespiratory fitness (CRF) in children in the transition from kindergarten to basic school according to participation in organized sports and estimated the associations of CRF and body composition indices during the transition from childhood to preadolescence.

Methods: Children participated in the three-staged study (kindergarten, 6.6 years, n = 212; 1st grade, 7.6 years, n = 136; and 5th grade, 11.5 years, n = 142) for 5 years and were categorized into three groups according to their participation in organized sports in the study period (whole period, episodically, and never). Cardiorespiratory fitness was assessed by performing a 20-m shuttle run test, while body composition was measured by skinfold thicknesses, and physical activity was registered with an accelerometer. International gender- and age-specific CRF reference normativities were also used to characterize the participants.

Results: Children who participated consistently in organized sports had significantly higher CRF levels and lower body fatness (31.3 ± 13.5 laps in 20 m shuttle run; 21.1% ± 6.3% body fat) in 11.5 years than in children who had never participated in sports clubs (20.7 ± 12.0 laps in 20-m shuttle run; 26.1% ± 6.8% body fat). Body composition and CRF did not associate in consistently trained children. The proportion of 5th grade children demonstrating age-appropriate healthy CRF was almost threefold higher in the group of consistent sports training among both boys and girls than among non-members of sports clubs.

Conclusion: Consistent attendance in organized sports in childhood and early preadolescence ensures higher CRF and healthier body composition than in children who had no experience of organized sports.

The Influence of Obesity on Nutrition and Physical Activity during COVID-19 Pandemic: A Case-Control Study

Obesity is one of the important risk factors for a severe course of COVID-19. Maintaining a healthy body weight through diet and physical activity is a reasonable approach to preventing a SARS-CoV-2 infection or in alleviating its course. The goal of the study was to determine the influence of obesity on nutrition and physical activity during the COVID-19 pandemic. A total of 964 respondents, including 227 individuals with a body mass index (BMI) ≥30 kg/m2 were evaluated in this study. In the case of 482 respondents, including 105 individuals (21.8%) with BMI ≥ 30 kg/m2, the data were collected during the pandemic period from 1 June to 31 August 2020. The remaining 482 individuals were the “pre-pandemic” group, selected via propensity score matching (PSM) out of the 723 National Health Program study participants whose data was collected in 2017−2019. The evaluated dietary health factors were quantitatively similar in patients with BMI of either <30 kg/m2 or ≥30 kg/m2 and showed no significant changes during the pandemic. The diets of those who suffered from obesity prior to the pandemic showed the evaluated unhealthy nutritional factors to be less pronounced in comparison with those of individuals with BMI < 30 kg/m2. During the pandemic, the BMI ≥ 30 kg/m2 group showed a significant increase in the overall calorie intake (by 319 kcal; p = 0.001) and an increased consumption of total carbohydrates 299.3 ± 83.8 vs. 252.0 ± 101.5; p = 0.000), sucrose (51.7 ± 30.0 vs. 71.6 ± 49.9; p = 0.000), plant protein (26.3 ± 12.1 vs. 29.3 ± 8.3; p = 0.040), total fat (73.1 ± 42.6 vs. 84.9 ± 29.6; p = 0.011) and saturated fatty acids (29.5 ± 16.4 vs. 34.3 ± 13.9; p = 0.014) in comparison with the pre-pandemic period. The energy and nutritional value of the diets of BMI < 30 kg/m2 individuals did not change between the pre-pandemic and pandemic period. Before the pandemic, the level of leisure physical activity of the BMI ≥ 30 kg/m2 group was significantly lower than of those with BMI < 30 kg/m2. Such differences were not observed in the levels of physical activity at work or school. The pandemic did not alter the amount of physical activity either during leisure time or at work/school in individuals with BMI ≥ 30 kg/m2. However, respondents without obesity exercised significantly less during the pandemic than before. In conclusion, the pandemic altered the diets and levels of physical activity in the Polish population, with dietary changes observed in individuals with BMI ≥ 30 kg/m2 and changes in physical activity observed in those with BMI < 30 kg/m2.

Out-of-School Sports Participation Is Positively Associated with Physical Literacy, but What about Physical Education? A Cross-Sectional Gender-Stratified Analysis during the COVID-19 Pandemic among High-School Adolescents

Physical literacy (PL) is one of the main concepts related to lifelong physical activity (PA) and physical fitness (PF), but there is a lack of information on factors that might be associated with PL in adolescents from southeastern Europe. This study aimed to evaluate the associations between PF, participation and achievement in physical education (PE), out-of-school participation in sports, and PL in high school adolescents from Croatia. Participants were 298 high school students aged 14−18 years (191 females). Variables included school age, PE grade, sports participation, anthropometric indices, four PF tests, and PL (evidenced by CAPL-2-knowledge and understanding questionnaire (CAPL-2-KU) and PLAYself questionnaire). Gender-stratified analyses of differences were conducted using the t-test for independent samples or the Mann-Whitney test. Associations between variables were calculated with Pearson’s product moment correlation or Spearman’s rank order correlation. PF was positively correlated CAPL-2-KU in both genders. PE grade was significantly associated with PLAYself score (Pearson’s correlation = 0.36 and 0.38, p < 0.001 for boys and girls, respectively) but not with the CAPL-2-KU score. School age was not correlated with PL among boys, but there was a significant but negligible correlation between CAPL-2-KU and school age in girls (<2% of the common variance). Adolescents involved in sports had better PL and PF compared with adolescents not involved in sports. In conclusion, participation in out-of-school sports offers a good base for developing PL. Although this study took part over the COVID-19 pandemic period when the regular PE curriculum was significantly altered, the poor associations between school age and PL could lead to the assumption that the current PE curriculum does not allow for improvement of PL in later high school age, which warrants further investigation.

Factors associated with a low level of physical activity in adolescents from La Rioja (Spain)

INTRODUCTION

Compliance with the recommendations regarding physical activity by adolescents is poor despite its proven benefits on their health.

OBJECTIVE

The objective of this study was to analyse the physical activity engagement in an adolescent population, evaluating its relationship with various indicators of physical and psychological health, as well as the influence of different sociodemographic variables as potential predictors.

METHODS

A cross-sectional study was applied to a sample of 761 students (14.51 ± 1.63 years) from 25 schools in La Rioja (Spain). Physical activity engagement, hours of nightly sleep, maximum oxygen uptake, health-related quality of life, self-esteem, body image satisfaction, adherence to the Mediterranean diet, body mass index, academic performance and various sociodemographic factors were analysed for all participants.

RESULTS

Being older, being a girl, having a low/medium socioeconomic level, living in unfavourable environments for practicing physical activity, not doing extracurricular sports activities, and being dissatisfied with body image were all predictors of a low physical activity engagement. Likewise, physical activity engagement reported positive associations with health-related quality of life, self-esteem, hours of nightly sleep, adherence to the Mediterranean diet and maximum oxygen uptake.

CONCLUSIONS

Interventions aimed at promoting physical activity must take into account these predictive factors, trying to favor their performance, especially in the most vulnerable groups.

Are There Common Correlates of Adolescents' Sport Participation and Screen Time?

Objective: This study aimed to identify intrapersonal, interpersonal, and environmental correlates of leisure-time participation in sports and examine whether they are also associated with screen-time among adolescents. Methods: Adolescents from eight schools in Victoria, Australia were recruited for this study. Participants (n = 400) comprised of an even distribution of boys (51%) and girls (49%) aged 12-16 years. Their engagement in leisure-time activities (including sports and screen-time) and 13 potential correlates were self-reported. Multinomial logistic regression analyses examined correlates of sports and screen-time participation categories, accounting for clustering by school and adjusting for significant sociodemographic characteristics. Results: The majority (76%) participated in leisure-time sports and exceeded screen-time recommendations (<2 h/day) on both weekdays (69%) and weekend days (85%). Greater internal motivation for sports was positively associated with sports participation and inversely associated with screen-time on weekend days, respectively. Fewer barriers, positive family and coach support and more neighborhood sporting opportunities were significantly associated with greater sports participation. Neighborhood social norms were inversely associated with sports participation. Preference for sports was associated with less weekday and weekend screen-time. Friend support for sports was inversely associated with weekday screen-time. Access to sports facilities in the local neighborhood was associated with more weekday and weekend screen-time. Conclusion: Internal motivation for sports was associated with both sports participation and less screen-time. Preference for leisure-time sports and friend support for sports were associated with less screen-time. Future research should continue to explore common correlates of multiple leisure-time behaviors to inform the development of effective intervention strategies.

"I Gave Up Football and I Had No Intention of Ever Going Back": Retrospective Experiences of Victims of Bullying in Youth Sport

Bullying is a global issue that, beyond school, is present in different social contexts, such as sport environments. The main objective of this study was to get to know the experiences of victims of bullying in sport throughout their youth sport training. Semi-structured interviews to four Spanish women and seven Spanish men were carried out, within an age range of 17–27 (M_age = 21 years, SD = 3.69). The following main themes were established by means of a hierarchical content analysis: (a) “bullying characterization,” (b) “dealing with bullying,” and (c) “consequences of bullying.” The results show the presence of physical, verbal and social bullying in the sport context, with the changing room being the space where this type of behavior is most frequently developed. Most victims show an internal attribution (self-blame) for the bullying event, related to their motor skills and their personal physical and psychological characteristics. Double victimization can be observed, at the sport club and at the educational center. Passive strategies are used to deal with the situation, while little support is shown by sport agents (teammates and coaches). The victims, as a consequence of the bullying experience, suffer from short and long-term negative effects on a psychosocial level. The study highlights the necessity to design and implement programs focused on the prevention, detection and intervention of bullying for sport organizations, bearing in mind all the agents that make them up (coaches, management teams, families, and players). Furthermore, the importance of promoting the creation of safe sport environments, free from any kind of violence, is emphasized.

Surveillance of physical activity and sedentary behaviour in czech children and adolescents: a scoping review of the literature from the past two decades

BACKGROUND

This study aimed to map the available evidence related to physical activity (PA) and sedentary behaviour (SB) in Czech children and adolescents and suggest future directions and improvements to strengthen the surveillance of PA and SB in the Czech Republic.

METHODS

The search of articles published between January 2000 and December 2020 included the Medline and Medvik databases and a manual search in eight Czech journals related to the topic. This review followed the "Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews".

RESULTS

Out of 350 identified articles, 79 articles met the criteria for selection and referred to 27 studies. The majority of the articles were cross-sectional (89%), approximately two-thirds of the articles (61%) examined only PA, and half of the articles (51%) employed device-based assessments. Approximately 47% of the articles reported the prevalence of physical inactivity on the basis of inconsistently defined recommendations. Approximately 14%, 23%, and 10% of the articles focused on active transportation, organized PA (including physical education or leisure-time PA), and parent-child PA, respectively.

CONCLUSIONS

Future studies need to focus on longitudinal design and interventions, randomly selected samples, a mix of device-based and self-reported methods, and the recognition of health-related 24-hour time use patterns. This review advocates the government-supported development of a national surveillance system that will help to reduce insufficient PA and excessive SB.

Dauerhaftes Sporttreiben im Sportverein und motorische Entwicklung: Ergebnisse der MoMo-Längsschnittstudie (2003–2017)

Bereits im Kindes- und Jugendalter gilt die motorische Leistungsfähigkeit als wichtiger Gesundheitsmarker. Auf Basis von Daten der Motorik Modul-Studie wird in diesem Artikel längsschnittlich über die Jahre 2003–2017 untersucht, inwieweit sich Sportvereinsmitglieder, die konstant im Sportverein aktiv waren, hinsichtlich ihrer motorischen Entwicklung von denjenigen unterscheiden, die nie im Sportverein aktiv waren. Es wurden Daten aus drei Messwellen untersucht: T1 (2003–2006), T2 (2009–2012) und T3 (2014–2017). Aus insgesamt N = 1092 Teilnehmenden, von denen über T1 bis T3 Daten zur Motorik vorlagen, wurden all diejenigen mit konstanter Mitgliedschaft und Nicht-Mitgliedschaft im Sportverein über drei Messwellen ausgewählt. Das sind 46 % der Gesamtstichprobe (N = 498). Von den N = 498 Teilnehmer*innen (Alter T1: 8,9 ± 3,8 Jahre, T2: 15,1 ± 3,9 Jahre, T3: 20,3 ± 4,0 Jahre) waren 15 % dauerhafte Sportvereinsmitglieder mit Wettkampfengagement, 53 % dauerhafte Sportvereinsmitglieder ohne Wettkampfengagement sowie 32 % dauerhaft Sportvereinsabstinente. Zur Ermittlung der motorischen Leistungsfähigkeit wurden konditionelle und koordinative Fähigkeiten anhand des MoMo-Testprofils erhoben (Kondition: Standweitsprung, Liegestütz, Fahrrad-Ausdauertest, Koordination: Seitliches Hin- und Herspringen, Einbeinstand, Balancieren rückwärts). Die Unterschiede in der Entwicklung wurden anhand von alters- und geschlechtsadjustierten Perzentilen mittels Varianzanalysen mit Messwiederholung berechnet, mit dem Sozialstatus als Kovariate. Innerhalb der Sportvereinsmitglieder waren Teilnehmende mit niedrigem Sozialstatus deutlich unterrepräsentiert. Insgesamt betrachtet, ist die Entwicklung der koordinativen und konditionellen Fähigkeiten bei Sportvereinsmitgliedern als signifikant besser zu beurteilen im Vergleich zu Sportvereinsabstinenten (Modell Koordination * Sportverein: df = 3,870 | F = 2,931 | p = 0,021 | ETA = 0,015 | f = 0,123; Modell Kondition * Sportverein: df = 4 | F = 3,794 | p = 0,005 | ETA = 0,048 | f = 0,225). Die Ergebnisse untermauern die Wichtigkeit der Sportvereine für die motorische Entwicklung von Kindern, Jugendlichen und jungen Erwachsenen in Deutschland.

Five-Year Changes in Community-Level Sport Participation, and the Role of Gender Strategies

Background: The rate of participation in community-based sport by boys and men has been double that of girls and women. Contributing to this is the fact that some sports have been traditionally male-only or at least very male-dominated.

Aim: The aim of this study was to investigate changes in participation in sport by sex and age across 10 major sports in Australia over a 5-year period. In conjunction with the analysis of participation trends, the gender strategies that were developed and implemented during this time are reviewed.

Methods: This study encompassed all sport participants registered with one of 10 State Sporting Associations in Victoria, Australia in 2015 and in 2019. Participation rates by region, age and sex were calculated. State sport and health policies relating to female participation in sport were reviewed.

Results: There were 749,037 registrations in 2015 and 868,266 in 2019. A comparison between 2015 and 2019 shows increases in participation for women and girls across all age groups (4–84 years), and highest increases for those aged 4 (6.6%) and 5–9 (4.7%). For boys there was a considerable decrease in participation for those aged 5–9 years (−3.8%).

Discussion: This study provides evidence that whilst participation in sport is still dominated by males, the gap might be gradually closing and this is in line with recent strategies and investments into sport and wider cultural developments in society. The implications of these findings are discussed.

Influence of an increased number of physical education lessons on the motor performance of adolescents-A non-interventional cohort study

Increasing the amount of regular physical education lessons in school is currently discussed in many countries in order to increase physical activity in youth. The purpose of this study was to compare the motor performance of pupils from an observation group participating in a school trial of two additional physical education lessons (5 lessons of each 50 min/week) without a specific intervention program to a control group with a regular amount of three physical education lessons (3 lessons of each 50 min/week) as indicated by the standard Austrian school curriculum. In this cohort study motor performance of 140 adolescents (12.7±0.5 years) was assessed by means of the German Motor Performance Test 6–18 over a period of 1.5 years with measurement time points before (T1), after eight months (T2) and at the end of the observation period (T3). Two- and three-way mixed analysis of variance were used to detect time, group and interaction effects. Although the observation group demonstrated a higher total motor performance score at all time points (P = 0.005), the improvement over time in total motor performance (P < 0.001) was more pronounced in the control group. Girls and boys developed differently over time (time*gender interaction: P = 0.001), whereby group allocation did not affect this interaction (time*gender*group: P = 0.167). Anyway, girls of control group tend to benefit most of additional physical education lessons. Sports club members scored significantly higher in motor performance across the observation period (P = 0.018) irrespective of group allocation. These findings indicate that there could be a ceiling effect in what the pupils could achieve in terms of motor performance as the pupils of the observation group might have reached this point earlier than their counterparts in the control group. Nevertheless, sports club membership seems to reveal some benefits. Whether improving quality and specificity of the single physical lessons might be superior to merely adding additional ones needs to be confirmed in future studies.

PaLS Study: How Has the COVID-19 Pandemic Influenced Physical Activity and Nutrition? Observations a Year after the Outbreak of the Pandemic

The restrictions implemented to prevent the spread of the SARS-CoV-2 virus have impacted the majority of life domains. To evaluate their potential consequences on physical activity (PA) and dietary habits among Polish undergraduates, a survey consisting of the IPAQ-SF, authors' questions based on the Polish National Institute of Public Health recommendations, and authors' questions scaled -5/0/5 on personal opinion was created and administered between 22 February and 3 April 2021. A total of 1323 students met the study conditions (1021 females, 297 males, 5 did not specify gender, mean age: 22 years old (SD = 4), mean BMI = 22.27 kg/m² (SD = 3.87)). A total of 27.21% of students were in the low, 48.53% in the moderate, and 24.26% in the high PA group. A total of 71.94% estimated that the pandemic had a negative impact on their PA, 8.16% no impact, and 19.9% a positive impact. A total of 35.5% had an insufficient intake of vegetables, 34.3% declared adding salt to meals, and 31.6% ate animal-based products the majority of days in a week or every day. A total of 51.02% assessed the impact of the pandemic on their nutrition as negative, 20.11% did not notice changes, and 28.87% reported a positive impact on their dietary habits. Most of the students saw harmful pandemic effects on their diet and PA compared to the times before restrictions. This can lead to a higher prevalence of non-communicable diseases (NCDs) in the future.

Seasonal changes in the physical activity levels of youth Gaelic football players

This study quantified changes in physical activity (PA) levels attained by adolescents during Gaelic football (GF) participation across two time points in a season and determined if these changes affected their overall daily PA levels. A total of 130 adolescents (65 females;15.3 ± 1.5 years) wore an activPAL accelerometer to determine total moderate PA (MPA), vigorous PA (VPA) and moderate-to-vigorous PA (MVPA) during a seven-day measurement period, including during GF. The PA measurement was completed at "preseason" (T1) and "in-season" (T2) timepoints. Between T1 and T2, females significantly increased time spent in MVPA daily (p < 0.001, d = 0.95), on Gaelic football days (GFDs) (p = 0.036; d = 0.30), on non-Gaelic football days (NGFDs) (p < 0.001; d = 0.43), and during GF (p < 0.001, d = 0.90). Males did not record any significant changes in PA over time (p > 0.05). At T2, there were no significant differences in time spent in MVPA daily, on GFDs and NGFDs, and during GF between the genders (p > 0.05). The results suggest that the change in daily PA levels by females is a consequence of increased MVPA during GF and reduced PA barriers across the season.

Effect of Physical Activity on Adolescent Obesity Status over Time: A Latent Growth Modeling Approach

This study aims to examine the longitudinal influence of physical activity (PA) on obesity among normal-weight adolescents in South Korea. A total of 1347 data samples from the Korean Children and Youth Panel Survey from 2011 to 2014 were used. Latent growth modeling was applied. PA was assessed by the hours spent on PA during physical education (PE) classes in the last week. Body mass index for age was considered to determine obesity status. PA during PE positively predicted the intercept of obesity status, but it was not associated with the slope of obesity status. Although a longitudinal effect of PA was not identified, PA could influence the initial status of obesity. Because obesity in early years could steadily influence future obesity status, early detection and intervention for adolescent obesity are necessary. Moreover, more studies examining the effect of PA during PE on obesity status among adolescents should be conducted to identify the association between PA during PE and obesity status over time.

Youth Perspectives on What Makes a Sports Club a Health-Promoting Setting-Viewed through a Salutogenic Settings-Based Lens

Sports participation has the potential to contribute to young people’s health. A prerequisite for young people to benefit from sports is that they stay in sports. Studies that consider both personal and contextual factors are needed to unpack the broader health-promoting potential of youth sports. The purpose of the study is to contribute to knowledge about the health-promoting potential of young people’s participation in organized sports by exploring youth perspectives on what makes a sports club health-promoting with a focus on health resources that young people consider important for sports club participation. For this cross-sectional study a brief survey was conducted with 15–16 year old students (n = 123) at two schools in Sweden, asking three open-ended questions about their participation in sports. The study used a salutogenic theory-driven analysis in combination with statistical analysis. Five health resources that young people consider important for sports club participation are revealed. On an individual, more ‘swimmer’-related level, these are personal well-being and social relations, including relationally meaningful activities, and on an organizational level, relating to the ‘river’, that sports clubs offer a supportive and well-functioning environment. For sports clubs to be health-promoting settings for young people and thus hopefully to reduce drop-out, we need a more sustainable approach emphasizing drop-in, drop-through, and drop-over as a continuous iterative process. We also need to consider the complexity of sports participation for young people, involving individual, organizational and environmental issues.

Impact of early sports specialisation on paediatric ECG

Athletes of pediatric age are growing in number. They are subject to a number of risks, among them sudden cardiac death (SCD). This study aimed to characterize the pediatric athlete population in Switzerland, to evaluate electrocardiographic findings based on the International Criteria for electrocardiography (ECG) Interpretation in Athletes, and to analyze the association between demographic data, sport type, and ECG changes. Retrospective, observational study of pediatric athletes (less than 18 years old) including medical history, physical examination, and a 12-lead resting ECG. The primary focus was on identification of normal, borderline, and abnormal ECG findings. The secondary observation was the relation between ECG and demographic, anthropometric, sport-related, and clinical data. The 891 athletes (mean 14.8 years, 35% girls) practiced 45 different sports on three different levels, representing all types of static and dynamic composition of the Classification of Sports by Mitchell. There were 75.4% of normal ECG findings, among them most commonly early repolarization, sinus bradycardia, and left ventricular hypertrophy; 4.3% had a borderline finding; 2.1% were abnormal and required further investigations, without SCD-related diagnosis. While the normal ECG findings were related to sex, age, and endurance sports, no such observation was found for borderline or abnormal criteria. Our results in an entirely pediatric population of athletes demonstrate that sex, age, and type of sports correlate with normal ECG findings. Abnormal ECG findings in pediatric athletes are rare. The International Criteria for ECG Interpretation in Athletes are appropriate for this age group.

Educational and Social Exergaming: A Perspective on Physical, Social, and Educational Benefits and Pitfalls of Exergaming at Home During the COVID-19 Pandemic and Afterwards

Physical inactivity and coronavirus disease 2019 (COVID-19) signify two pandemics with negative physical, mental, and economic consequences. Younger and older people have not reached the recommended physical activity level for years. Societal restrictions due to COVID-19 additionally reduce opportunities for physical activity, and they increase social isolation. Here, we outline how playing exergames with others (social exergaming) at home could foster physical and mental health and promote communication and discussions on exergaming. Accordingly, we highlight the educational and social benefits of exergaming at home and delineate the concept of Educational and Social Exergaming (EASE). We outline specific benefits and pitfalls of exergaming regarding its physical and nonphysical effects, including educational values of discussing exergaming experiences and related topics. Moreover, we discuss the relevance of practical guidelines for educational and social exergaming at home as well as prospects for future research. Overall, educational and social exergaming could alleviate several detrimental effects of both pandemics on the health and well-being of people of all ages.

Preschool physical activity and fitness predicts conceptual, verbal and perceptual skills at school

This study investigated longitudinal relationships between physical activity (PA), fitness and cognitive performance at early years. In total, 147 children at the age of 6.6 and 7.6 years participated in the study. PA and sedentary behaviour (SB) were registered with accelerometer. Skinfold thickness measurements were used to assess body composition. Children's cardiorespiratory fitness (CRF), muscular strength and speed-agility fitness was assessed using PREFIT fitness test battery and static balance by EUROFIT test battery. Cognitive skills were measured with modified Boehm-3 test. Linear regression analyses showed that PA at the age of 6.6 years was positively, while SB was negatively associated with the conceptual skills at the age of 7.6 years after adjusting for confounders. Positive associations were observed between CRF, lower-limbs strength relative to fat-free mass, static balance at the age of 6.6 years with perceptual skills at 7.6 years in unadjusted analysis. PA and fitness were not associated with verbal abilities. Physically active lifestyle and CRF, relative explosive strength of the lower limbs, balance at 6.6 years in kindergarten predict conceptual and perceptual skills, but does not predict verbal abilities 1 year later at first grade in school. SB affects negatively conceptual skills.

[Factors associated with a low level of physical activity in adolescents from La Rioja (Spain)]

INTRODUCTION

Compliance with the recommendations regarding physical activity by adolescents is poor despite its proven benefits on their health.

OBJECTIVE

The objective of this study was to analyse the physical activity engagement in an adolescent population, evaluating its relationship with various indicators of physical and psychological health, as well as the influence of different sociodemographic variables as potential predictors.

METHODS

A cross-sectional study was applied to a sample of 761 students (14.51 ± 1.63 years) from 25 schools in La Rioja (Spain). Physical activity engagement, hours of nightly sleep, maximum oxygen uptake, health-related quality of life, self-esteem, body image satisfaction, adherence to the Mediterranean diet, body mass index, academic performance and various sociodemographic factors were analysed for all participants.

RESULTS

Being older, being a girl, having a low/medium socioeconomic level, living in unfavourable environments for practicing physical activity, not doing extracurricular sports activities, and being dissatisfied with body image were all predictors of a low physical activity engagement. Likewise, physical activity engagement reported positive associations with health-related quality of life, self-esteem, hours of nightly sleep, adherence to the Mediterranean diet and maximum oxygen uptake.

CONCLUSIONS

Interventions aimed at promoting physical activity must take into account these predictive factors, trying to favor their performance, especially in the most vulnerable groups.

Organized Sport Participation, Physical Activity, Sleep and Screen Time in 16-Year-Old Adolescents

This study aimed to examine the association of different frequencies of organized sport participation (OSP) with physical activity, cardiorespiratory fitness, body composition, sleep, and screen time among adolescents. A cross-sectional study involving 315 16-year-old adolescents was conducted. OSP was self-reported, being categorized as 0 times a week, less than three times a week, 4-5 times a week, and 6-7 times a week, on average. Screen time was also self-reported but physical activity and sleep duration were objectively measured. Cardiorespiratory fitness and body composition were measured using a maximal cycle ergometer test and a dual-energy X-ray absorptiometry (DXA) scan, respectively. An analysis of covariance revealed a significant association between OSP and physical activity (F (3, 286) = 14.53, p < 0.01), cardiorespiratory fitness (F (3, 236) = 17.64, p < 0.01), screen time (F (3, 294) = 8.14, p < 0.01), body fat percentage (F (3, 292) = 11.84, p < 0.01), and fat free mass (F (3, 290) = 5.76, p < 0.01. No significant association was found between OSP and sleep duration. Post hoc analyses showed that OSP at least four times a week was beneficial to favorable physical activity levels, cardiorespiratory fitness, screen time, and body composition and may therefore serve as a valuable tool in battling unhealthy lifestyle behaviors among adolescents.

The Effect of COVID-19 Lockdown Measures on Physical Activity Levels and Sedentary Behaviour in a Relatively Young Population Living in Kosovo

To abate the spread of the COVID-19 virus, different restriction measures were imperative, limiting the possibility to be engaged in physical activity. Therefore, this study aimed to evaluate the effect of COVID-19 lockdown on physical activity (PA) levels expressed as energy expenditure (MET-min/week) and sedentary behaviour in Kosovo. The possible association between PA levels and other factors was analyzed. 1633 participants (age range: 13 to 63 years; mean: 24.70 ± 9.33 years; body height: 172 ± 10.57 cm; body mass: 69.10 ± 13.80 kg; BMI: 23.09 ± 3.63 kg/m2) participated in the study, categorized by age, gender, BMI, and living area. An online survey, including an adapted version of the IPAQ-SF, was administered once during lockdown to assess PA levels and sedentary behaviour both before and during COVID-19 lockdown. The Wilcoxon signed-rank, Mann-Whitney U and Kruskal-Wallis rank of sum tests were used for statistical analysis. COVID-19 restrictions had a negative impact on the types of and overall PA levels MET-min/week (p < 0.001). Sedentary behaviour significantly increased during COVID-19 restrictions (p < 0.001). Higher decreases in MET-min/week during lockdown were observed among males, young and young adults, overweight, and urban-living participants. Finally, COVID-19 restrictions decreased the PA levels and MET-min/week, and increased sedentary behaviour also in a relatively young cohort. Such differences were dependent on several factors.

[The Person Who Plays Handball Needs the Ball, the Contact and the Community - Changes in Sport Club Activities Due to the COVID-19 Pandemic and its Significance for Sports Clubs]

Ziel der Studie Sportvereine spielen eine wichtige Rolle für die Bewegungs- und damit auch die Gesundheitsförderung in Deutschland. Die vorliegende Studie befasst sich vor dem Hintergrund der Corona-bedingten Einschränkungen mit den Veränderungen in der Angebotsstruktur und deren Bedeutung für die Sportvereine.

Methode Es wurden 15 Experteninterviews mit Vertretern und Vertreterinnen bayerischer Sportvereine geführt. Die Daten wurden transkribiert und mittels thematischer Analyse induktiv ausgewertet.

Ergebnisse Von den Vereinen wurden umfangreiche Aktivitäten entwickelt, um den Mitgliedern auch unter den Rahmenbedingungen der COVID-19-Pandemie Möglichkeiten für sportliche Aktivitäten zu bieten. Die Vereinsmitglieder hätten dabei mit viel Verständnis auf die Veränderungen und Einschränkungen im Angebot reagiert. Die Nutzung der neu geschaffenen digitalen Angebote durch die Mitglieder scheint sich von der Nutzung der realen Kurse zu unterscheiden. Das längerfristige Potenzial der digitalen Angebote wird jedoch weitgehend skeptisch betrachtet. Insbesondere der im Sport normalerweise immanente Gemeinschaftsaspekt würde den Teilnehmenden an digitalen Formaten fehlen.

Schlussfolgerungen Die Anstrengungen der Sportvereine, ein geregeltes Bewegungsprogramm auch unter den Rahmenbedingungen einer Pandemie bereit zu stellen, betont deren Bedeutung für Prävention und Gesundheitsförderung. Aus Public-Health-Sicht bieten die Veränderungen in der Angebotsstruktur darüber hinaus das Potenzial, auch unter normalisierten Rahmenbedingungen beibehalten zu werden. Hierzu sind aber weiterführende Forschungsarbeiten notwendig.

Contrasts in fitness, motor competence and physical activity among children involved in single or multiple sports

Study aim: While there is wide debate around specialization in one sport, there is a lack of information about fitness levels and motor competence of children participating in single or multiple sports.

Material and methods: The study involved 358 fifth-grade children who participated in a set of health-related fitness and motor competence tests over two consecutive years. A subsample of children (n = 109) wore an accelerometer for seven consecutive days. The independent samples t-test and ANCOVA were used to compare differences between single and multi-sport participants in study variables and changes between baseline and follow-up.

Results: Multi-sport participants performed better in shuttle run (baseline/follow-up; p = 0.001/p = 0.006), push-up (p = 0.006/p = 0.036), and five leap tests (p = 0.001/p = 0.009) in baseline than single sport participants among boys. Likewise, multi-sport participants showed significantly more improvement in the throwing and catching combination test between study years among boys F1,159 = 3.570, p = 0.030. Among girls, no differences were found in any study variable between single and multi-sport participants.

Conclusions: From the perspective of fitness and motor competence tests, there are no arguments for participating in just one sport at an early age. Instead, multi-sport participants performed better than single sport participants in the majority of test variables.

[Determinants of health in adolescence: cardiorespiratory fitness and body composition]

Introduction

Introduction: cardiorespiratory fitness and body composition are determining indicators of health status during adolescence. The objective of the study was to analyze the relationship of both parameters with indicators of mental and psychosocial health, lifestyle habits, and sociodemographic variables, establishing their predictive factors. Method: a cross-sectional study was conducted with a representative sample of 761 students (14.51 ± 1.63 years old) from 25 educational centers in a northern region of Spain. Body mass index, maximum oxygen uptake, health-related quality of life, self-esteem, hours of nightly sleep, adherence to the Mediterranean diet, physical activity engagement, academic performance, and different sociodemographic factors were analyzed for all participants. Results: the results determined that being a boy, being younger, sleeping fewer hours at night, and presenting a lower academic performance were predictors of suffering from obesity, while being younger and being a migrant were predictors of being overweight. On the other hand, lower physical activity engagement, poorer academic performance, being a migrant, and not practicing extracurricular sports activities were predictive factors of cardiorespiratory fitness in the risk zone. In addition, the environment for performing physical activity and socioeconomic level also showed associations with cardiorespiratory fitness. Conclusions: given the influence of body composition and cardiorespiratory fitness on the physical and psychosocial health of adolescents, promotion strategies are required that take into account the identified predictors, with special attention to promoting healthy lifestyles.

Physical Activity, Screen Time, and Sleep Duration of Children Aged 6-9 Years in 25 Countries: An Analysis within the WHO European Childhood Obesity Surveillance Initiative (COSI) 2015-2017

BACKGROUND

Children are becoming less physically active as opportunities for safe active play, recreational activities, and active transport decrease. At the same time, sedentary screen-based activities both during school and leisure time are increasing.

OBJECTIVES

This study aimed to evaluate physical activity (PA), screen time, and sleep duration of girls and boys aged 6-9 years in Europe using data from the WHO European Childhood Obesity Surveillance Initiative (COSI).

METHOD

The fourth COSI data collection round was conducted in 2015-2017, using a standardized protocol that included a family form completed by parents with specific questions about their children's PA, screen time, and sleep duration.

RESULTS

Nationally representative data from 25 countries was included and information on the PA behaviour, screen time, and sleep duration of 150,651 children was analysed. Pooled analysis showed that: 79.4% were actively playing for >1 h each day, 53.9% were not members of a sport or dancing club, 50.0% walked or cycled to school each day, 60.2% engaged in screen time for <2 h/day, and 84.9% slept for 9-11 h/night. Country-specific analyses of these behaviours showed pronounced differences, with national prevalences in the range of 61.7-98.3% actively playing for >1 h/day, 8.2-85.6% were not members of a sport or dancing club, 17.7-94.0% walked or cycled to school each day, 32.3-80.0% engaged in screen time for <2 h/day, and 50.0-95.8% slept for 9-11 h/night.

CONCLUSIONS

The prevalence of engagement in PA and the achievement of healthy screen time and sleep duration are heterogenous across the region. Policymakers and other stakeholders, including school administrators and parents, should increase opportunities for young people to participate in daily PA as well as explore solutions to address excessive screen time and short sleep duration to improve the overall physical and mental health and well-being of children.

Sex-Related Differences in the Association of Fundamental Movement Skills and Health and Behavioral Outcomes in Children

This study aimed to assess whether sex moderates the association of fundamental movement skills and health and behavioral outcomes. In 170 children (10.6 ±0.3 years; 98 girls), path analysis was used to assess the associations of fundamental movement skills (Get Skilled, Get Active) with perceived sports competence (Children and Youth—Physical Self-Perception Profile), time spent in vigorous-intensity physical activity, sedentary time, and body mass index z score. For boys, object control skill competence had a direct association with perceived sports competence (β = 0.39; 95% confidence interval, CI [0.21, 0.57]) and an indirect association with sedentary time, through perceived sports competence (β = −0.19; 95% CI [−0.09, −0.32]). No significant association was observed between fundamental movement skills and perceived sports competence for girls, although locomotor skills were found to predict vigorous-intensity physical activity (β = 0.18; 95% CI [0.08, 0.27]). Perceived sports competence was associated with sedentary time, with this being stronger for boys (β = −0.48; 95% CI [−0.64, −0.31]) than girls (β = −0.29; 95% CI [−0.39, −0.19]). The study supports a holistic approach to health-related interventions and highlights a key association of perceived sports competence and the time children spend sedentary.

The physical activity of children and adolescents in Germany 2003-2017: The MoMo-study

With digitalization and virtual entertainment being the megatrends of the 21st century, there is reasonable concern about the role of physical activity (PA) in the daily life of children and adolescents. To identify risk-groups with insufficient PA and to guide interventions, continuous and representative tracking of PA is crucial. In this paper, representative PA data of children and adolescents from the Motorik-Modul (MoMo) baseline study (2003-2006, N = 4,528) is compared to those of Wave 2 (2014-2017, N = 3,708). Participants aged 4-17 were drawn out of 167 sample points in Germany and the data was weighted to ensure representativeness for Germany. Organized (sports clubs and schools) and unorganized (unorganized sports and playing outside) PA was measured by questionnaire and stratified by sex, age, and socioeconomic status. Contrary to common expectation, overall PA remained stable among youths in the past ten years, however, there is an ongoing trend towards organized forms of PA at the expense of unorganized sports and playing outside. Besides different trends in settings, there is inequality in PA distribution among socioeconomic status and gender, unequally pronounced in different settings.

Exercising in Times of Lockdown: An Analysis of the Impact of COVID-19 on Levels and Patterns of Exercise among Adults in Belgium

Countries all over the world implemented lockdowns to counteract COVID-19. These lockdowns heavily limited people’s exercise possibilities. At the same time, experts advocated to remain physically active to prevent future health problems. Based on an online survey, this study examines adults’ exercise levels and patterns during the COVID-19 lockdown in Belgium. Ordinal logistic regression analyses of 13,515 valid and population-weighted responses indicate a general increase in exercise frequencies, as well as in sedentary behavior. Except for people aged 55+, previously low active adults self-reported to exercise more during the lockdown. Among the people who were already high active before COVID-19, those above 55 years old, those with low education, those used to exercise with friends or in a sport club, and those who were not using online tools to exercise, self-reported to exercise less during the lockdown. Having less time, sitting more, and missing the familiar way and competitive element of exercising were the main reasons for a self-reported exercise reduction. Given the health risks associated with physical inactivity, results imply that governments should consider how those who were not reached can be encouraged to exercise during a lockdown. After all, additional COVID-19 lockdowns might be implemented in the future.
