'The Little Engine That Could': A Qualitative Study of Medical Service Access and Effectiveness among Adolescent Athletics Athletes Competing at the Highest International Level

Health Systems in High-Performance Sport: Key Functions to Protect Health and Optimize Performance in Elite Athletes

Enabling athletes to achieve peak performances while also maintaining high levels of health is contextually complex. We aim to describe what a 'health system' is and apply the essential functions of stewardship, financing, provision of services and resource generation to an Australian high-performance sport context. We introduce a fifth function that health systems should not detract from athletes' ability to achieve their sports goals. We describe how these functions aim to achieve four overall outcomes of safeguarding the health of the athletes, responding to expectations, providing financial and social protection against the costs of ill health, and efficient use of resources. Lastly, we conclude with key challenges and potential solutions for developing an integrated health system within the overall performance system in high-performance sport.

Sports Physiology in Adolescent Track-and-Field Athletes: A Narrative Review

The present study aimed to review the physiological aspects of adolescent track-and-field (TAF) athletes. A search of Scopus on 27/12/2022 using the syntax ABS (track-and-field) AND ABS (children) OR ABS (adolescent) showed 121 documents, and 45 were considered for further analysis. In addition, handsearching was conducted to identify Russian literature missing in Scopus. Differences were shown in performance characteristics among disciplines, especially between throwers and the other athletes. The sex difference in performance (ie, a better performance in boys than in girls) started in early adolescence. A relative age effect was more pronounced in athletes under 13 years old. Despite the wide use of nutritional supplements, an insufficient intake of vitamins has been found. The age of training onset and body weight were identified as risk factors for problems with menarche. The inclusion of track-and-field training programs in physical education was beneficial for health and physical fitness. The need to collaborate closely with parents and coaches was identified, especially, regarding education in topics such as the age of training onset, relative age effect, and doping. In conclusion, the existence of many disciplines with different anthropometric and physiological characteristics highlighted the need for a discipline-specific approach.

Injury acknowledgement by reduction of sports load in world-leading athletics (track and field) athletes varies with their musculoskeletal health literacy and the socioeconomic environment

Objective

Although injury burden prompts elite athletics (track and field) athletes to engage in injury management, little is known about their health literacy. We investigated musculoskeletal (MS) health literacy in world-leading athletics athletes and associations with prechampionship injury acknowledgement by reduction of training load in different socioeconomic environments.

Methods

Adult and youth athletics athletes (n=1785) preparing for World Championships were invited to complete the Literacy in Musculoskeletal Problems instrument and report acknowledgement of injury by reduction in training load during prechampionship tapering. Their socioeconomic standing was estimated through the Human Development Index of their home country. Demographic differences were examined using χ2tests and determinants of injury acknowledgement assessed using logistic regression.

Results

Complete data were obtained from 780 athletes (43.7%) with 26% demonstrating sufficient MS health literacy, higher in adult (41%) than youth (13%) athletes (p<0.001). Adult athletes at the uppermost socioeconomic level showed higher MS health literacy than athletes at lower socioeconomic levels (p<0.001). At the uppermost socioeconomic level, adult athletes with sufficient MS health literacy had increased likelihood of acknowledging an injury by reduction in training load compared with peers demonstrating insufficient MS health literacy (OR=2.45; 95% CI 1.33–4.53). Athletes at middle socioeconomic levels with sufficient MS health literacy had decreased likelihood for acknowledging an injury during tapering (OR=0.29; 95% CI 0.11–0.78).

Conclusions

The prevalence of sufficient MS health literacy in world-leading athletics athletes is low. Associations between MS health literacy and injury acknowledgement in these athletes vary with the resourcefulness of the socioeconomic environment, implying that health literacy and resources for medical and performance support should be ascertained concurrently.

Lower calcium and iron intake in adolescent gymnasts: A case of concern for youth sports nutrition

OBJECTIVES

Diet is important for the appropriate development and maturation of young amateur athletes. The aim of this study was to determine whether young gymnasts were consuming adequate amounts of nutrients, particularly calcium and iron.

METHODS

This cross-sectional survey was conducted in Portugal's Almada and Lisbon regions in 2020. To determine if participants' diet was adequate, weight, height, and skinfold measurements were taken. Dietary consumption was examined using two 24-h recalls. We collected data from 66 participants (60% females, 12-18 y of age), of whom 82% had normal weight and 39% had ideal body fat.

RESULTS

The daily total energy intake (TEI) was1605 ± 601 kcal. Of the TEI, 19%, 31%, and 50% were comprised of protein, fat, and carbohydrates, respectively. The most often consumed protein sources were poultry and ultra-processed meat products (52% and 45%, respectively). The average daily consumption of calcium and iron was 626 ± 293 and 9 ± 3 mg, respectively. Only 2 of the 66 participants had calcium intake within recommended levels, and 1of 5 had iron intake within recommended levels, the percentage of which was lower in girls than boys (7.5% versus 38.5%, P < 0.05).

CONCLUSIONS

Despite having a sufficient macronutrient distribution, Portuguese gymnasts consume a high amount of ultra-processed items and a low amount of calcium and iron. The low proportion of female gymnasts with adequate iron consumption is cause for worry in sports nutrition.

Behavioral activation / inhibition systems and lifestyle as predictors of mental disorders in adolescent athletes during Covid19 pandemic

The following study investigates the correlational relationship between behavioral activation/inhibition systems, lifestyle and mental disorders in Adolescent Athletes during the Covid-19 pandemic. Methods: Research methods are descriptive and correlational; “Of the eligible participants who were available during a COVID-19 quarantine period from June through August 2020 (N = 180), the Krejcie and Morgan Sampling Method was used to simplify the process of determining the sample size for a finite population [46], resulting in a calculation of N = 130 sample participants. to respond to Carver & White’s Behavioral activation/inhibition systems Scale (BIS/BAS), Mille’s Lifestyle Questionnaire and Goldberg & Williams’s General Health Questionnaire (GHQ-12). Data was analyzed using linear regression analysis and Pearson’s correlation coefficient. Results: Findings showed a positive correlation of statistical significance between behavioral inhibition systems (BIS) and mental disorders in Adolescent Athletes at the 0.01 level and a negative correlation of statistical significance between scaling components of the behavioral activation systems (BAS), lifestyle and mental disorders in Adolescent Athletes at the 0.05 level. Conclusions: Analyzing the data, it can thus be concluded that whilst behavioral inhibition and activation systems seem to work together to significantly predict mental disorders, lifestyle cannot.

'I always considered I needed injury prevention to become an elite athlete': the road to the Olympics from the athlete and staff perspective

In this study, we explored the perspectives about sports injury prevention of Belgium Olympic level athletes, coaches, managers and healthcare providers from various Olympic sports. We conducted a qualitative study, including 17 semistructured interviews. All interviews were transcribed verbatim and analysed by two independent coders through constant comparative data analysis based on Grounded Theory principles. Our findings overview the athlete's journey to becoming an elite athlete, and how an elite sports context influences and modulates injury prevention practice at this level. Participants described an elite athletic career as a continuous and adaptive evolving process. According to athletes and all stakeholders, sports injury prevention is a learning process shaped by individual experiences. This embodiment provides athletes with insight into the importance of ownership of their bodies and self-awareness. Thus, experience, communication, empowerment, knowledge, education, the elite athlete context and sports culture, all play a fundamental role in sports injury prevention. Our findings support the importance of contextual factors in sports injury prevention in an elite sports context. These results also bring practical implications on how we should approach injury prevention differently along an athlete's journey to becoming an elite athlete. Considering specific contextual factors and influencing the process through awareness, communication and a shared responsibility is essential to develop a healthy and successful athlete.
