A Review of Acute Physical Activity Effects on Brain and Cognition in Children

The effect of diverse sports skills interventions on physical fitness and brain development among Chinese high school students: a cluster randomized controlled trial study protocol

BACKGROUND

During adolescence, research concerning physical fitness and brain development has become a focal point in health and neuroscience. Academic debates on the precise impact of different sports skills on adolescent physical fitness lack consensus. While exercise's positive effects on brain development in children and older adults are well-documented, its specific impact on adolescents remains unexplored. A year-long trial explores how diverse sports skills affect adolescents' physical fitness and brain development. The study has a dual focus: first, to examine the potential correlation between sports skills acquisition and indicators of adolescent physical fitness; and second, to investigate the mechanisms of brain plasticity in adolescents. This comprehensive study is poised to fill knowledge gaps, providing a scientific basis for targeted health interventions in adolescent populations.

METHODS

This study will employ a randomized controlled cluster design involving senior high school students in Shanghai. The expected sample size is approximately 450 students, divided into four experimental groups and a control group. The experimental groups will undergo 1 year of sports skills training in basketball, football, tennis, and martial arts, while the control group will receive regular physical education classes. Prior to intervention, data will be collected on students' physical fitness, sports skills, levels of physical activity, and functional magnetic resonance imaging (fMRI) measurements. Rigorous control of variables will ensure comparability and experimental validity. For data analysis, specialized software tools, including SPSS 18.0, AMOS 18.0, Matlab R2013b, and EXCEL, will be employed for comprehensive analysis and interpretation, validating potential differences between experimental and control groups in various aspects of physical fitness and sports skills.

DISCUSSION

This experiment aims to provide substantial scientific evidence on the impact of sports skills learning on diverse indicators of adolescent physical fitness. In addition, it aims to elucidate the effects of exercise on adolescent brain plasticity and its specific underlying mechanisms. This comprehensive evidence base is poised to serve as a basis for more effective interventions in the future, providing enhanced scientific guidance for promoting holistic adolescent development. It also provides scholars and practitioners with fresh perspectives on adolescent health development.

Effectiveness of school-based active breaks on classroom behavior, executive functions and physical fitness in children and adolescent: a systematic review

Introduction

The classroom environment is ideal for promoting physical activity interventions since children spend most of their day there but often engage in sedentary behavior. Given this context, an emerging trend to promote physical activity is active breaks at school. This systematic review evaluated the effects of school-based physical activity interventions involving active breaks on children and adolescents' classroom behavior, executive functions, and physical fitness.

Methods

This review was guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. A literature search was conducted using PubMed, Web of Science, Scopus, and EBSCOhost. Studies published between January 2010 and August 31, 2023, including participants aged 5 to 18, were included. Interventions involving active breaks and outcomes related to classroom behavior, executive functions, and physical fitness were considered.

Results

Initially, 145 studies were identified, with 22 duplicates excluded. After screening 123 articles by title and abstract, 86 were excluded. Subsequently, 37 articles underwent full-text screening, resulting in 22 included studies. Six studies showed positive effects on classroom behavior; five studies showed improvements in executive functions, and only two studies indicated increases in physical fitness.

Discussion

This review suggests incorporating active breaks during school hours can improve classroom behavior in children and adolescents. However, the effects of active breaks on executive functions and physical fitness are unclear. More research is needed to fully understand the benefits of implementing active break programs in the classroom.

Student perceptions of U.S. based school day physical activity best practices in relation to accelerometer-based sedentary behavior and activity

Objective

To examine associations between student perceptions of school physical activity best practices and accelerometer-based physical activity during school days.

Methods

The sample was 758 students in grades 3rd-4th or 6th-7th (female-58 %; 31 % Black/African American) from 33 schools across five school districts in a Mid-Atlantic state in the U.S. Students completed the Perceptions of the Environment at School survey to assess perceived implementation of 11 school physical activity best practices and wore an Actical ankle accelerometer for 7 days between 2017 and 2019. Accelerometer cutpoints were applied for percent time in sedentary, light, and moderate-vigorous physical activity (MVPA) during school hours. Adjusted mixed effects linear regression models were used to predict percent time in each physical activity category, with separate models for elementary and middle school.

Results

More best practices were perceived by elementary versus middle schoolers (sum score = 3.3 versus 1.5, p < .01). For every additional best practice perceived, elementary schoolers spent 0.64 % less time in sedentary behavior (B = -0.62; SE = 0.27, p = .02), equivalent to ∼12 fewer minutes/week in sedentary behaviors, and 0.58 % more time in light activity (B = 0.58; SE = 0.25, p = .02; ∼10 more minutes/week). No associations observed for middle schoolers or MVPA.

Conclusions

Few best practices were perceived as being implemented in school. Elementary schoolers who perceived more best practices spent more time in light activity and less in sedentary behavior, but this relationship was not found among middle schoolers. Future research should promote implementation of school physical activity best practices and examine the linkage between implementation, student perceptions, and behavior change.Trial Registration: Clinical Trials, NCT03432715; Registered on 02/2/2018.

Unveiling the association between 24-hour movement guidelines and academic engagement in adolescents

BACKGROUND

The aim of this research is to examine the relationship between adherence to different possible combinations of the 24-hour movement guidelines and academic engagement in adolescents.

METHODS

The cross-sectional study involved 742 students (median = 15.00; interquartile range = 3.00), aged 12 to 17 years (422 girls; 56.9%). Physical activity, screen time, sleep duration, and academic engagement were measured using self-report measurements. A generalized additive mixed model and a generalized linear mixed model were used to examine the association between adherence to 24-hour movement guidelines and academic engagement. Age, sex, socioeconomic status, body mass index, and school were considered as covariates.

RESULTS

Students who met all three guidelines showed the highest levels of academic engagement. Conversely, the lowest levels of academic engagement were observed in those who did not meet any of the guidelines. In addition, students' academic engagement was higher as more 24-hour movement guidelines were met.

CONCLUSION

Our results suggest the importance of jointly promoting 24-hour movement guidelines, as it appears to have greater benefits on adolescent academic outcomes.

IMPACT

Not meeting any of the three 24-hour movement guidelines was associated with lower academic engagement. Meeting all three 24-hour movement guidelines was related to higher academic engagement. Previous research has focused on the association between the three 24-hour movement guidelines and academic performance. However, the relationships of these behaviors on academic engagement have been little studied. The results of this study highlight the importance of promoting these three behaviors in adolescent academic outcomes.

Resting-State Functional Connectivity Change in Frontoparietal and Default Mode Networks After Acute Exercise in Youth

BACKGROUND

A single bout of aerobic exercise can provide acute benefits to cognition and emotion in children. Yet, little is known about how acute exercise may impact children's underlying brain networks' resting-state functional connectivity (rsFC).

OBJECTIVE

Using a data-driven multivariate pattern analysis, we investigated the effects of a single dose of exercise on acute rsFC changes in 9-to-13-year-olds.

METHODS

On separate days in a crossover design, participants (N = 21) completed 20-mins of acute treadmill walking at 65-75% heart rate maximum (exercise condition) and seated reading (control condition), with pre- and post-fMRI scans. Multivariate pattern analysis was used to investigate rsFC change between conditions.

RESULTS

Three clusters in the left lateral prefrontal cortex (lPFC) of the frontoparietal network (FPN) had significantly different rsFC after the exercise condition compared to the control condition. Post-hoc analyses revealed that from before to after acute exercise, activity of these FPN clusters became more correlated with bilateral lPFC and the left basal ganglia. Additionally, the left lPFC became more anti-correlated with the precuneus of the default mode network (DMN). An opposite pattern was observed from before to after seated reading.

CONCLUSIONS

The findings suggest that a single dose of exercise increases connectivity within the FPN, FPN integration with subcortical regions involved in movement and cognition, and segregation of FPN and DMN. Such patterns, often associated with healthier cognitive and emotional control, may underlie the transient mental benefits observed following acute exercise in youth.

Selecting an appropriate control group for studying the effects of exercise on cognitive performance

Differences in expectations between experimental and control groups can influence the outcomes of exercise interventions, emphasizing the need to match expectations across study groups. This online study examined whether the expectations to improve the performance of different cognitive tasks differ between various activities commonly used in research on the effects of exercise and cognitive function. Two hundred and five middle-aged adults performed two reaction-time tasks and one memory task. They were then asked to rate, on a 1-5 Likert scale, their expectations to improve performance in those tasks should they engage in six types of activities for three months: brisk walking, resistance exercise, stretching and balance exercises, watching videos with lectures on art, history, and science, a program of relaxation techniques, and yoga/tai chi/meditation. Results revealed that the highest expectations for improvement were associated with relaxation techniques and yoga/tai chi/meditation. Some activities, such as brisk walking and stretch and balance exercises, shared similar expectations. Previous knowledge of the possible beneficial effects of exercise on cognitive performance also led to higher expectations. To establish causal relationships, researchers should strive to use activities that share similar expectations to improve performance for the experimental and control groups. The findings of this study provide such activity pairs. Finally, researchers should also try to match participants with and without prior knowledge of the benefits of exercise to cognitive function between experimental and control groups.

An active break program (ACTIVA-MENTE) at elementary schools in Chile: study protocol for a pilot cluster randomized controlled trial

Background

Physical inactivity is prevalent in childhood. Schools can be an ideal context to promote the regular practice of physical activity since children spend there a large part of the day. In this sense, an emerging and current trend is active breaks at school. This article presents a study protocol that seeks to assess the feasibility and effectiveness of an intervention with active breaks (ACTIVA-MENTE program) in a school context on physical activity, on-task classroom behavior, and the physical activity enjoyment in schoolchildren.

Methods

The protocol includes children aged 10 to 11 years. Two groups will be randomized (intervention and control groups). The intervention group will use the active break program, ACTIVA-MENTE, which consists of the application of a 4-min, 30-s video with moderate to vigorous-intensity physical activity. These breaks will be taken 6 times a day in the classes for 6 weeks. The total physical activity will be measured with accelerometers (Actigraph wGT3X-BT), the on-task behavior through the Direct Behavior Rating Scale and the level of enjoyment through the Physical Activity Enjoyment Scale.

Discussion

Previous research reported that active breaks have positive results in physical activity levels. This study will be one of the few to design active breaks through videos without depending on the presence of a physical education teacher and it can also provide new findings on the effectiveness of an active break's structure (e.g., types of exercises and intensity) on the indicated outcomes.

Expected results

It is expected that the ACTIVA-MENTE program can be a suitable program for school settings, potentially increasing physical activity levels, and the commitment to the task, as well as be a pleasant moment for the students.

Association of physical activity and fitness with executive function among preschoolers

It is well-documented in the literature that high levels of regular physical activity (PA), low levels of sedentary behavior (SB), and high levels of cardiorespiratory fitness (CRF) are associated with superior cognitive functioning, especially with regard to older populations. However, concerning other age groups (e.g., preschoolers) the available evidence documenting such a positive relationship is relatively scarce. Thus, this study aimed to investigate the association of time spent in different PA intensity zones and CRF with executive functions (EFs) in preschool-age children. To this end, preschoolers (n = 127) aged 3 to 6 years were recruited from 9 kindergarten classes in 2 districts of Shenzhen, China. The amount and the intensity of PA were assessed via accelerometry, and the CRF level was quantified by the 20-meter shuttle run test. EFs including inhibitory control and working memory were assessed using the one-on-one iPad-based Early Year Toolbox. Results suggested that children who had a higher CRF level ("impulse control" scores: β = 0.34, p < .001; "Go" accuracy: β = 0.31, p < .001; "No-Go" accuracy: β =0.28, < .001) and spentmore time in moderate-to-vigorous physical activity (MVPA) ("impulse control" scores: β = 0.50, p < .001; No-Go" accuracy: β = 0.52, p < .001) had higher scores on inhibitory control tasks, and those who had a higher CRF level had higher scores on a working memory task (β = 0.24, p < .05). The findings are discussed in light of the positive roles of MVPA and CRF for promoting EFs, but also consider the disproportionate association of PA and CRF with working memory relative to inhibition.

Does exposure to nature make children more intelligent? Analysis in Polish children with and without ADHD

Previous studies have shown that exposure to nature and physical activity (PA) may be associated with higher intelligence in children. We examined whether there is an association between lifelong exposure to greenspace and bluespace and intelligence in children aged 10-13 with and without attention deficit hyperactivity disorder (ADHD), and whether PA mediates this association. The sample (N = 714) was collected within the NeuroSmog case-control study, where children with (N = 206) and without ADHD (N = 508) were recruited from 18 towns in Southern Poland. Nature exposure was estimated as the sum of the z-scores of the objective and perceived measures. Objective greenspace exposure was defined as the percentage of grass and tree cover in 500 m and 1 km buffers around lifelong residential addresses, respectively. Objective bluespace exposure was defined as the percentage of water cover in 500 m and 1 km buffers. Perceived greenspace/bluespace was measured as the parent-rated availability, quality, and use of greenspace/bluespace. Intelligence was assessed using the Polish version of the Stanford-Binet Intelligence Scales, 5th edition (SB5). SB5 Full Scale Intelligence Quotient (IQ), Nonverbal IQ, Verbal IQ, five factor and ten subtest scores were analysed as outcomes. The associations between nature and IQ scores were assessed by linear regressions separately for cases and controls, adjusting the models for sex, parental education, and urbanicity. Structural equation modeling was implemented to test whether PA mediated the association between nature and intelligence. None of the greenspace or bluespace measures were consistently associated with intelligence. PA was not found to be a mediator. We did not find evidence that higher lifelong nature exposure is associated with higher intelligence in Polish schoolchildren with or without ADHD. This casts doubts on whether exposure to nature has relevant influence on IQ.

Acute enhancement of executive functions through cognitively challenging physical activity games in elementary physical education

This study examined the effects of cognitively challenging physical activity games on students’ executive functions and situational interest in physical education. Participants were 144 fourth- and fifth-grade students (75 boys, 69 girls) from four elementary schools. A four-group, repeated measures, cross-over quasi-experimental design was used in this acute experiment including a physical education session. One fourth- and one fifth-grade class from each school were randomly assigned to Group 1 with cognitively challenging physical activity games, Group 2 with a session for teaching soccer skills, Group 3 with a session for teaching track and field skills, and Group 4 (waiting-list control group) with cognitively challenging physical activity games after the post-test. Pre- and post-test measures for executive functions and a post-test measure for situational interest were included. Group 1 students, who were involved in cognitively challenging physical activity games, improved their scores in the executive functions more than students who participated in the sessions with soccer or track and field skills and waiting-list control group students. The positive effects on students’ executive functions were replicated when the cognitively challenging physical activity games session was implemented in the waiting-list control group. Some improvements on executive functions for students who participated in the soccer skills session were found. Students who played the cognitively challenging physical activity games reported higher scores on novelty compared to students in the soccer or track and field groups. These results support the effectiveness of the cognitive challenging physical activity games for triggering students’ executive functions in physical education.

Exposure to greenspace and bluespace and cognitive functioning in children - A systematic review

BACKGROUND

The field of greenspace and bluespace research in relation to cognitive outcomes is rapidly growing. Several systematic reviews have already been published on this topic but none of them are specific to cognitive outcomes in the entire age range of children. Moreover, only a few of them have examined the effects of bluespace in addition to greenspace. Also, theses reviews are focused either only on observational studies or experimental studies. Our systematic review focuses on cognitive outcomes in relation to greenspace and bluespace in children and adolescents aged 0-18; it captures both observational and experimental studies. Cognitive outcomes are presented according to an evidence-based taxonomy of human cognitive abilities: the Cattell-Horn-Carroll (CHC) theory.

METHODS

We conducted searches in the PubMed and PsychInfo databases, from their inception dates to 17 December 2021. We used three-text terms related to outcome, exposure, and population as well as MeSH terms for outcome and population. Further, the reference lists and existing reviews were searched ("snowball" search) until 21 April 2022 to detect additional studies. For the results reporting, we followed the updated guidelines of the Preferred Reporting Items for Systematic reviews and Meta Analyses (PRISMA). We included observational and experimental studies on greenspace or bluespace exposure in relation to cognitive functioning, published in English, German, or Polish. Two reviewers independently checked study eligibility and extracted data. Two reviewers evaluated the risk of bias according to the Office of Health Assessment and Translation (OHAT) tool. At all stages, discrepancies between the two reviewers were solved via discussion with a third reviewer.

RESULTS

Records identified from PubMed (n = 2030) and PsycINFO (n = 1168) were deduplicated and screened. Twenty one reports were first selected. The "snowball" search revealed 16 additional reports. Altogether, 39 studies (17 experimental and 22 observational) published in 37 reports were qualified. The data extraction showed that the methodology used in the studies was heterogenous and the findings were inconsistent. The majority of the studies investigated attentional functioning, which we subdivided into two categories according to the CHC theory: attentional control and reaction and decision speed (12 studies) and attentional control and processing speed (10 studies). Eleven studies investigated working memory and/or short-term memory that we categorized as CHC working memory capacity. Nine studies investigated intellectual functioning, which we categorized as CHC general ability, fluid reasoning, and comprehension-knowledge. Two studies investigated visual-spatial skills, which we categorized as CHC visual processing and psychomotor speed. One study measured parent-reported attention; two studies examined early childhood/cognitive development; three studies examined decision-making and self-regulation, which can be categorized as several CHC theory abilities.

DISCUSSION

The heterogeneity of the included studies does not permit clear conclusions for our review. In accordance with previous systematic reviews, greenspace and bluespace were not more strongly related to a particular domain of cognitive functioning than other cognitive domains, and no effects of age or type of exposure assessment on the association between nature and cognition were detected. Further research is needed, including state-of-the-art of assessment of cognitive outcomes and diverse exposure assessment methods within both observational and experimental approaches. Expertise will be required in several domains, such as environmental epidemiology, cognitive psychology, and neuropsychology. Systematic review registration number (INPLASY): 202220018.

Effect of Physical Exercise in Real-World Settings on Executive Function of Typical Children and Adolescents: A Systematic Review

OBJECTIVE

The aim of this paper is to provide a systematic review of research on physical exercise in real-world settings on executive function of typical children and adolescents.

METHODS

The CNKI, WOS, PubMed, ScienceDirect, and SPORTDiscus databases were searched by computer. Two researchers independently screened the literature, extracted data, and evaluated the risk of bias in the included literature. Statistical analysis was performed using frequency and percentage and the χ² test.

RESULTS

A total of 49 articles was included. Acute (moderate intensity lasting 30-50 min) and long-term (interventions of moderate intensity of 30-50 min at least 3 times a week for 17 weeks or more) physical exercises in real-world settings have positive intervention effects on executive function. Furthermore, for acute interventions, closed skills are more efficient for inhibitory control, open skills are more efficient for working memory and cognitive flexibility, and open-continuous and closed-sequential skills are the most efficient; long-term interventions with open skills, sequential skills, and open-sequential skills are more effective.

CONCLUSION

Physical exercise in real-world settings has a good promotion effect on typical children and adolescents, and motor skills with open and/or sequential attributes are more helpful in improving executive function.

A mixed method investigation of teacher-identified barriers, facilitators and recommendations to implementing daily physical activity in Ontario elementary schools

Background

Fewer than 17% of children worldwide are meeting the international recommendations for daily physical activity. Since most children are in school for the bulk of their day, the classroom has been identified as an ideal space to incorporate physical activity opportunities. In Ontario (Canada), the Daily Physical Activity (DPA) policy aims to ensure all elementary school children receive a minimum of 20 min of moderate to vigorous physical activity each school day during instructional time. However, a 2015 evaluation found that only half of Ontario teachers were meeting this expectation; this work advocated for additional research to monitor implementation and its predictors and to further identify fidelity recommendations. Thus, the current study investigated contemporary factors influencing DPA fidelity in Ontario elementary schools and provides teacher-identified recommendations to support DPA implementation.

Methods

The first part of the study was a quantitative approach surveying 186 elementary school teachers across Ontario. Descriptive statistics including frequencies and means were used to characterize barriers, facilitators, and recommendations to DPA implementation. Spearman’s correlations were used to assess the relation between the likelihood of DPA implementation and intrapersonal factors of gender, teaching experience, prior DPA training and personal physical activity participation. The second part of the study consisted of a qualitative approach using teacher interviews to explore in-depth teachers’ recommendations to support DPA implementation. A thematic analysis was used to analyze the transcripts and identify recommendations for DPA.

Results

Survey results showed that only 23% of teachers met the mandated 20 min of DPA per day. Barriers to implementation included space and time constraints, inadequate training, student behavioural issues and low self-efficacy. Gender, teaching experience and prior DPA training were not related to the likelihood of DPA implementation. Teachers who rated themselves as more physically fit were more likely to implement DPA. Teacher interviews elucidated key areas for improving DPA implementation including greater DPA training opportunities, resources, community partnerships, accountability and strategies that support school-wide implementation.

Conclusion

The current study demonstrated that fidelity to the DPA policy in Ontario elementary schools is on the decline. This work highlights unique factors implicated in DPA fidelity and brings to the forefront teacher recommendations to improve DPA implementation.

Exploring the Acute Effects of the Daily Mile™ vs. Shuttle Runs on Children’s Cognitive and Affective Responses

Background: This study investigated the acute effects of two physical activity (PA) bouts on children’s cognitive and affective responses. Methods: Twenty-nine participants (16 boys and 13 girls; M_age = 9.34 years, SD = 0.48), using a within-subjects crossover design, performed three 15-min conditions: (a) TDM—The Daily Mile™; (b) 12 repeated 30–45-s shuttle runs at ≥ 85% HR_MAX; and (c) a sedentary control condition. Cognitive performance (i.e., Stroop, Digit Span, and Corsi blocks) was measured before PA and 1 and 30 min post-PA. Felt Arousal and Feeling Scale self-report scales were administered before, during, and after PA. Results: The results show no changes following the TDM condition relative to the sedentary control condition in cognitive responses. However, when comparing the shuttle runs condition to the sedentary control condition, participants showed higher arousal, an improved reaction time, and lower self-reported pleasure at 1 min post-PA. Nevertheless, at 30 min post-PA, participants’ pleasure values were higher in the shuttle runs condition than they were before PA. Conclusions: When comparing PA conditions, shuttle runs enhanced reaction time and might thus be seen as an option to implement or modify PA opportunities in school settings.

Relationship between Physical Activity and Emotional Regulation Strategies in Early Adulthood: Mediating Effects of Cortical Thickness

We investigated the relationship between physical activity (PA) and emotional regulation strategies among college students to establish the mediating role of cortical thickness. A total of 60 university students (18−20 years old) were enrolled in this study. The International Physical Activity Questionnaire (IPAQ-L) was used to estimate PA levels. Based on the International Physical Activity Working Group standards, PA levels were divided into low, medium, and high PA groups; emotional regulation strategies were determined by the Emotion Regulation Questionnaire (ERQ), including the Cognitive Reappraisal Scale (CR) and the Expressive Suppression Scale (ES). Structural magnetic resonance imaging (MRI) was used to measure cortical thickness. Differences in use of the ES strategy among high, medium, and low PA groups were not marked. However, compared to the low PA group, the CR strategy was frequently used in the high PA group, with a thicker right hemisphere rostral anterior cingulate cortex (rrACC). PA levels were positively correlated with thickness of the rrACC cortex (r = 0.398, p = 0.002 < 0.05) and CR strategy (r = 0.398, p = 0.002 < 0.05), and negatively correlated with the ES strategy (r = −0.348, p = 0.007 < 0.05). The rrACC cortical thickness played a partial mediating role in the relationship between PA and CR strategy, accounting for 33.1% of total effect values. These findings indicate that although the negative correlation between PA and ES was not significant, the positive correlation between PA with CR was significant, and rrACC thickness played a partial mediating role in the relationship between PA and CR, providing new evidence toward comprehensively revealing the relationship between PA, rrACC cortical thickness, and emotion regulation strategies.

Physical Education with Eduball Stimulates Non-Native Language Learning in Primary School Students

Although the neuronal mechanisms of action and cognition are related, the division of intellectual and physical lessons is standard in schools. This is surprising, because numerous studies show that integrating physical education (PE) with teaching content stimulates critical skills. For example, several experiments indicate that Eduball-based PE (i.e., lessons in a sports hall during which students play team mini-games with educational balls with printed letters, numbers, and other signs) develops mathematical and language competencies. At the same time, the Eduball method does not slow down learners’ physical development. However, we have little knowledge about the effects of such techniques on non-native language learning. Consequently, the absence of incorporating core academic subjects into PE in dual-language schools or during foreign language education is exceptionally high. Here, we replicated the Eduball experiment, but with the goal of testing this method for non-native language learning. Thus, the intervention occurred in a dual-language primary school and we evaluated second language (L2) learning. As before, we used the technique of parallel groups (experimental and control); in both groups, there were three 45-min PE classes per week. In the experimental class, two of them were held using Eduball. After a half-year experiment, children from the experimental group (one second-grade, N = 14) improved their non-native language skills significantly more than their peers from the control group (one second-grade, N = 12). These findings demonstrate that Eduball-type intervention stimulates non-native language learning in children. Hence, our report suggests that specific body training forms can support L2 learning.

Acute Effects of Various Movement Noise in Differential Learning of Rope Skipping on Brain and Heart Recovery Analyzed by Means of Multiscale Fuzzy Measure Entropy

In search of more detailed explanations for body-mind interactions in physical activity, neural and physiological effects, especially regarding more strenuous sports activities, increasingly attract interest. Little is known about the underlying manifold (neuro-)physiological impacts induced by different motor learning approaches. The various influences on brain or cardiac function are usually studied separately and modeled linearly. Limitations of these models have recently led to a rapidly growing application of nonlinear models. This study aimed to investigate the acute effects of various sequences of rope skipping on irregularity of the electrocardiography (ECG) and electroencephalography (EEG) signals as well as their interaction and whether these depend on different levels of active movement noise, within the framework of differential learning theory. Thirty-two males were randomly and equally distributed to one of four rope skipping conditions with similar cardiovascular but varying coordinative demand. ECG and EEG were measured simultaneously at rest before and immediately after rope skipping for 25 mins. Signal irregularity of ECG and EEG was calculated via the multiscale fuzzy measure entropy (MSFME). Statistically significant ECG and EEG brain area specific changes in MSFME were found with different pace of occurrence depending on the level of active movement noise of the particular rope skipping condition. Interaction analysis of ECG and EEG MSFME specifically revealed an involvement of the frontal, central, and parietal lobe in the interplay with the heart. In addition, the number of interaction effects indicated an inverted U-shaped trend presenting the interaction level of ECG and EEG MSFME dependent on the level of active movement noise. In summary, conducting rope skipping with varying degrees of movement variation appears to affect the irregularity of cardiac and brain signals and their interaction during the recovery phase differently. These findings provide enough incentives to foster further constructive nonlinear research in exercise-recovery relationship and to reconsider the philosophy of classical endurance training.

Physical Activity, Fitness, and Executive Functions in Youth: Effects, Moderators, and Mechanisms

Over the last decade, a growing body of research has examined the link between physical activity, fitness, and cognitive function in children and adolescents. Physical activity experimental research conducted with children and adolescents has identified selectively greater effects for tasks requiring higher order executive functions. As such, the primary aim of our chapter is to provide an overview of findings from systematic reviews and meta-analyses that have examined the effects of physical activity on measures of executive function in child and adolescent populations. We begin our chapter with definitions of key concepts associated with physical activity, fitness and cognitive function. We then provide a synthesis of systematic reviews and meta-analyses that have examined the acute and chronic effect of physical activity on EFs. Following this, we discuss the quantitative (e.g., time, intensity) and qualitative (e.g., type) characteristics of physical activity that may moderate effects. The next section focuses on the neurobiological, psychosocial and behavioral mechanisms responsible for the effect of physical activity on executive functions. We conclude by highlighting the limitations of the existing evidence base and providing recommendations for future research.

Six Weeks of Basketball Combined With Mathematics in Physical Education Classes Can Improve Children's Motivation for Mathematics

This study investigated whether 6 weeks of basketball combined with mathematics once a week in physical education lessons could improve children's motivation for mathematics. Seven hundred fifty-seven children (mean age = 10.4 years, age range: 7–12 years) were randomly selected to have either basketball combined with mathematics once a week (BM) or to have basketball sessions without mathematics (CON). Children in BM and CON motivation for classroom-based mathematics were measured using the Academic Self-Regulation Questionnaire (SRQ-A) before (T0) and after the intervention (T1). Among the BM, levels of intrinsic motivation, feelings of competence, and autonomy were measured using the Post-Experimental Intrinsic Motivation Inventory (IMI) questionnaire acutely after a basketball session combined with mathematics and immediately after a session of classroom-based mathematics. BM had significantly higher acute levels of perceived autonomy (+14.24%, p < 0.0001), competencies (+6.33%, p < 0.0001), and intrinsic motivation (+16.09%, p < 0.0001) during basketball sessions combined with mathematics compared to when having classroom-based mathematics. A significant decrease in the mean for intrinsic motivation was observed from T0 to T1 for CON (−9.38%, p < 0.001), but not for BM (−0.39%, p = 0.98). BM had a more positive development in intrinsic motivation compared to CON from T0 to T1 (p = 0.006), meaning that BM had a positive influence on children's intrinsic motivation for classroom-based mathematics. This study indicates that basketball combined with mathematics is an intrinsically motivating way to practice mathematics, which also has a positive influence on children's general intrinsic motivation for mathematics in the classroom.

Acute Effects of an Afterschool Running and Reading Program on Executive Functioning in Children: An Exploratory Study

Objective: Emerging research within school settings suggests acute forms of physical activity and exercise lead to improvements in executive functioning among children. However, research pertaining to these effects within the afterschool setting remains limited. The primary purpose of this study was to investigate the acute effects of a community-based afterschool running and reading program on executive functioning in 8 to 12-year-old children. Method: Fifty participants were initially recruited to participate in this study. However, due to the COVID-19 pandemic, data collection was terminated prematurely which resulted in a sample size of 15 participants. Participants (N = 10) from School 1 completed two batteries of executive function assessments (i.e., inhibition, switching, and updating) separated by 15-min of running or 15-min of sedentary reading. Whereas, only 5 participants from School 2 completed assessments of executive functioning prior to and following the running portion of the program (due to the early termination of data collection). Results: Overall, executive function scores improved across each assessment following the running condition when compared to the reading condition (School 1). Inhibition scores significantly improved, and these effects were very large (School 1). Across both schools, improvements in executive functioning following the running portion of the program ranged from small-large in effect size. Conclusion: Findings from the present study provide initial evidence for the acute effects of a community-based afterschool running and reading program on executive functioning in children. Future research with larger samples in afterschool settings is recommended to replicate this preliminary work.

New Directions in Exercise Prescription: Is There a Role for Brain-Derived Parameters Obtained by Functional Near-Infrared Spectroscopy?

In the literature, it is well established that regular physical exercise is a powerful strategy to promote brain health and to improve cognitive performance. However, exact knowledge about which exercise prescription would be optimal in the setting of exercise–cognition science is lacking. While there is a strong theoretical rationale for using indicators of internal load (e.g., heart rate) in exercise prescription, the most suitable parameters have yet to be determined. In this perspective article, we discuss the role of brain-derived parameters (e.g., brain activity) as valuable indicators of internal load which can be beneficial for individualizing the exercise prescription in exercise–cognition research. Therefore, we focus on the application of functional near-infrared spectroscopy (fNIRS), since this neuroimaging modality provides specific advantages, making it well suited for monitoring cortical hemodynamics as a proxy of brain activity during physical exercise.

Cognitive-Motor Dual Task Interference Effects on Declarative Memory: A Theory-Based Review

Bouts of exercise performed either prior to or immediately following study periods enhance encoding and learning. Empirical evidence supporting the benefits of interventions that simultaneously pair physical activity with material to be learned is not conclusive, however. A narrative, theory-based review of dual-task experiments evaluated studies in terms of arousal theories, attention theories, cognitive-energetic theories, and entrainment theories. The pattern of the results of these studies suggests that cognitive-motor interference can either impair or enhance memory of semantic information and the manner in which physical activity impacts working memory within executive processing appears to explain disparate outcomes. The integration and timing of physical movements in concert with the type of information to be encoded and remembered appears to be a critical requirement for learning. These observations have implications for the role of physical activity in education, rehabilitation, and gerontological settings.

Active Commute in Relation to Cognition and Academic Achievement in Children and Adolescents: A Systematic Review and Future Recommendations

Active commuting to school (ACS) is an important source of physical activity among children. Recent research has focused on ACS and its benefits on cognition and academic achievement (AA), factors important for success in school. This review aims to synthesize literature on the relationship between ACS and cognition or AA among children and adolescents. Peer-reviewed articles in PubMed, Web of Science, PsycINFO and Cochrane Library assessing ACS with cognition and/or AA among children, until February 2019, were selected. Twelve studies across nine countries (age range 4–18.5 years) were included. One study used accelerometers, whereas all others used self-report measures of ACS. A wide range of objective assessments of cognitive functioning and AA domains were used. Five among eight studies, and four among six found a positive relationship between ACS and cognitive or AA measure, respectively. Four studies found dose–response relationships, and some studies found sex differences. The quantitative analysis found that ACS was not significantly associated with mathematics score (odds ratio = 1.18; CI = 0.40, 3.48). Findings are discussed in terms of methodological issues, potential confounders, and the strength of the evidence. Future studies should conduct longitudinal studies and use objective measures of ACS to understand this relationship further.
