Effects of physical education interventions on cognition and academic performance outcomes in children and adolescents: a systematic review and meta-analysis

Participation in physical activity and sport in adolescent girls from Middle Eastern backgrounds

OBJECTIVES

This study investigated the barriers and facilitators to physical activity and sport participation among adolescent girls from Middle Eastern backgrounds. These factors were explored through the perspectives of both adolescent girls and parents of adolescent girls, living in Australia.

DESIGN

A qualitative study design was used to understand perceived barriers and facilitators to physical activity and sport in adolescent girls. Participants were 18 adolescent girls and 9 parents of adolescent girls, all of Middle Eastern backgrounds, living in Western Sydney, Australia. Data were collected through five focus groups and four one-on-one interviews, separated for girls and parents. Data were analysed using an inductive approach and thematic analysis.

RESULTS

Three main themes (family, social support, religion and culture) and nine subthemes were identified. The main facilitators for physical activity and sport included the values and presence of an active family role model, religion to encourage lifelong physical activity skills, and promotion of physical activity from peers, school, and social media. The predominant barriers to physical activity and sport included established cultural norms and traditional gender roles, which were often influenced by religion and culture, and extended time using technology.

CONCLUSION

The findings of the current study show the complex relationships between family, religion, and culture when promoting physical and sport participation. Such factors highlight the need to develop culturally tailored physical activity interventions that consider the perceived barriers and facilitators for adolescent girls' participation from Middle Eastern backgrounds.

Academic achievement and healthy lifestyle habits in primary school children: an interventional study

Purposes

First, to examine the relationship between primary school children's academic achievement and healthy lifestyle habits. Second, to evaluate the effectiveness of two different 5-month physical education interventions (traditional physical education vs. coordinative physical education) on children's academic achievement. Third, to examine whether variations of anthropometric variables, fitness level, gross motor coordination, physical activity level, sedentary time, attentional performance, fruit and vegetable consumption, meal frequency and type of physical education intervention could predict children's academic achievement variations.

Methods

Before and after the intervention, Italian language and mathematics skills, anthropometric variables (weight, height, body fat percentage, BMI), physical fitness (aerobic fitness, muscular strength, flexibility), gross motor coordination, attentional performance (processing speed, concentration performance, performance accuracy, attentional and inhibitory control), physical activity level, sedentary time and eating habits (meal frequency, fruit and vegetable consumption) were assessed in 161 Italian primary school children, randomly assigned to a traditional physical education group or to a coordinative physical education group.

Results

Physical activity level, gross motor coordination and aerobic fitness moderately predicted mathematics skill (R2 = 17%). Moreover, physical activity level, aerobic fitness and muscular strength moderately predicted Italian language skill (R2 = 21%). Intervention type differently affected academic achievement. Specifically, Italian language and mathematics skills significantly improved only after traditional intervention. Fruit consumption increase was positively associated with the improvement in academic achievement. Coordinative physical education intervention was associated with a lower probability of improvement in Italian language and mathematical skills.

Conclusion

Motor ability and lifestyle habits may have a positive influence on academic achievement in children. Unexpectedly, traditional physical education intervention resulted to be more effective on both Italian language and mathematical skills.

Exploring the mediating role of promoting school physical activity on the relationship between low socioeconomic status and academic achievement and school climate: evidence from 4,990 Chilean schools

There is evidence that promoting school physical activity (PSPA) benefits children and adolescents, but little is understood about how this promotion may relate to academic achievement and school climate across varying levels of socioeconomic status (SES). Hence, the study aimed to address this knowledge gap by examining two main objectives: (1) determining the association between PSPA and academic achievement and school climate according to schools' SES and (2) exploring the potential mediating role of PSPA in the relationship between schools' SES and academic achievement and school climate. This cross-sectional study at the school level focused on 4,990 schools (including public, subsidized, and private schools) that participated in the National Educational Study 2018 (Chile), which was applied to primary schoolchildren (4th grade, aged 8-10 years). Schools were divided into non-PSPA (n = 4,280) and PSPA (n = 710) during the year 2018. Changes in academic achievement from 2017 to 2018 and school climate were considered. PSPA was associated with improvements in maths (low-SES OR: 1.80, p < 0.001) and reading (middle-SES OR: 1.45, p = 0.029; low-SES OR: 1.47, p < 0.001). The indirect effect (IE) showed that PSPA partially mediated the relationship between SES and academic achievement in reading (IE = 1.017; SE = 0.12; 95%CI, -1.27, -0.77), maths (IE = -1.019; SE = 0.12; 95%CI, -1.25, -0.78), and school climate (IE = -0.46; SE = 0.52; 95%CI, -0.56, -0.35). In conclusion, PSPA was linked to positive changes in academic achievement, especially among low SES, and PSPA presented a potential mediating role in the relationship between SES of schools and academic achievement and school climate.

Investigating the Potential of a Conversational Agent (Phyllis) to Support Adolescent Health and Overcome Barriers to Physical Activity: Co-Design Study

BACKGROUND

Conversational agents (CAs) are a promising solution to support people in improving physical activity (PA) behaviors. However, there is a lack of CAs targeted at adolescents that aim to provide support to overcome barriers to PA. This study reports the results of the co-design, development, and evaluation of a prototype CA called "Phyllis" to support adolescents in overcoming barriers to PA with the aim of improving PA behaviors. The study presents one of the first theory-driven CAs that use existing research, a theoretical framework, and a behavior change model.

OBJECTIVE

The aim of the study is to use a mixed methods approach to investigate the potential of a CA to support adolescents in overcoming barriers to PA and enhance their confidence and motivation to engage in PA.

METHODS

The methodology involved co-designing with 8 adolescents to create a relational and persuasive CA with a suitable persona and dialogue. The CA was evaluated to determine its acceptability, usability, and effectiveness, with 46 adolescents participating in the study via a web-based survey.

RESULTS

The co-design participants were students aged 11 to 13 years, with a sex distribution of 56% (5/9) female and 44% (4/9) male, representing diverse ethnic backgrounds. Participants reported 37 specific barriers to PA, and the most common barriers included a "lack of confidence," "fear of failure," and a "lack of motivation." The CA's persona, named "Phyllis," was co-designed with input from the students, reflecting their preferences for a friendly, understanding, and intelligent personality. Users engaged in 61 conversations with Phyllis and reported a positive user experience, and 73% of them expressed a definite intention to use the fully functional CA in the future, with a net promoter score indicating a high likelihood of recommendation. Phyllis also performed well, being able to recognize a range of different barriers to PA. The CA's persuasive capacity was evaluated in modules focusing on confidence and motivation, with a significant increase in students' agreement in feeling confident and motivated to engage in PA after interacting with Phyllis. Adolescents also expect to have a personalized experience and be able to personalize all aspects of the CA.

CONCLUSIONS

The results showed high acceptability and a positive user experience, indicating the CA's potential. Promising outcomes were observed, with increasing confidence and motivation for PA. Further research and development are needed to create further interventions to address other barriers to PA and assess long-term behavior change. Addressing concerns regarding bias and privacy is crucial for achieving acceptability in the future. The CA's potential extends to health care systems and multimodal support, providing valuable insights for designing digital health interventions including tackling global inactivity issues among adolescents.

The role of parental involvement in academic and sports achievement

According to previous research results and our systematic review on this topic (Kovács et al., 2022), the positive impact of parental involvement on academic achievement was revealed. However, it is unclear how parental involvement in sports contributes to sports performance and academic achievement. In this study, our main questions are about the differences in academic achievement, in participation in sports activity, and in sports results among pupils of parents involved or not involved in sports and education. To answer these questions, a questionnaire survey was conducted among 7th and 8th-grade students learning in three primary schools in a Hungarian city (N = 121). Based on the scale of parental involvement, three groups were differentiated: 1) children of parents not involved in either education or sports (N = 33), 2) children of parents involved in education only (N = 38), and 3) children of parents involved in both education and sports (N = 47). In order to examine this data, cluster and factor analysis, a Chi-square test and ANOVA, and linear regression were used. Our results showed, children of parents involved in both sports and education are overrepresented among students who received awards because of their sports performance (59.6%), among members of sports talent management programs (29.8%), and among those who achieved first place in national sports competitions (47.8%). They also seem to be the ones most intent on staying engaged, in the future, in regular and competitive sport activities (57.4% and 55.3%). On the contrary, the highest percentage of children of parents involved in education belongs to those who were given awards because of excellent academic achievement (71.1%). As far as personality traits are concerned, obsessive passion (OP) is the most characteristic of pupils with non-involved parents (M = 0.37, SD = 0.95) and least characteristic of children with parents involved in education (M = -0.17, SD = 0.94). Belonging to both groups with involved parents can be considered a negative predictor of OP (βt = -0.259* [-1.019, -0.078], βt + s = -0.237* [-0.930, -0.030]). In conclusion, it can be detected that there exists a positive interrelation between parental involvement in sports and education, and the academic and sports performance of their children.

Exploring the link between perceived physical literacy and academic performance outcomes: insights from the EHDLA study

Objective

The aim of this study was to verify the relationship between perceived physical literacy (PPL) and academic performance outcomes among Spanish adolescents aged 12-17 years.

Methods

This cross-sectional study is a secondary examination utilizing data derived from the Eating Healthy and Daily Life Activities (EHDLA) project. The Spanish Perceived Physical Literacy Instrument for Adolescents (S-PPLI) was used to evaluate the PPL of the participants. To determine academic performance, the numerical grades for each subject were added together and then divided by the total number of subjects.

Results

Overall, a positive trend in the association between S-PPLI scores and academic performance was observed. We identified two significant ranges within the S-PPLI scores. First, there was a significant range between 9 and 33 points on the S-PPLI, indicating an inverse association with academic performance. Second, another significant range was observed at scores of 34 points or higher on the S-PPLI, suggesting a positive association with academic performance. Participants with low PPL had the lowest academic performance (mean = 6.4; bias-corrected and accelerated (BCa) bootstrapped 95% confidence interval (CI): 6.2-6.6). Conversely, those adolescents with high PPL had the highest academic performance (mean = 6.9; BCa bootstrapped 95% CI: 6.6-7.1). Significant differences were found between low PPL and medium PPL (p-adjusted = 0.031) and between low PPL and high PPL (p-adjusted = 0.031).

Conclusions

Increased physical literacy could be a relevant factor for achieving greater academic performance in adolescents. This study has potential implications for physical education instructors, school leaders, and healthcare practitioners.

Effects of open and closed skill exercise interventions on executive function in typical children: a meta-analysis

BACKGROUND

The effects of open and closed skill exercise interventions for executive function in children and adolescents have received widespread attention. Open skill refers to the skill of performing motor tasks in an unpredictable environment; closed skill refers to the skill of performing motor tasks in a stable environment. However, the results of related studies are currently controversial and Meta-analysis is urgently needed.

METHODS

After computer searches of CNKI, Wan-Fang, VIP, WOS, PubMed, and EBSCO databases, two researchers independently screened articles, extracted information, and evaluated the quality of the articles. This study was statistical analyzed using Stata 16.0 software.

RESULTS

A total of 31 articles were included, including 2988 typical children. Open, closed, continuous and sequential skills all improved executive function in typical children to varying degrees, but open and sequential skills were more effective in improving executive function, particularly in the former in the working memory (SMD=-0.833, P < 0.001) and in the latter in the inhibitory control (SMD=-0.834, P < 0.001) and cognitive flexibility (SMD=-0.903, P < 0.001). Long-term, moderate- intensity interventions were better than acute, vigorous-intensity interventions for executive function, with long-term interventions reflected in working memory (SMD=-0.579, P < 0.001) and moderate-intensity interventions reflected in all three dimensions of executive function (P < 0.01). Intervention periods, intervention intensity and continuous and sequential skills classified by action structure play a significant moderating role. Better results for long-term, sequential structural action interventions based on open skills (P < 0.001); better results for acute, moderate intensity, sequential structural action interventions based on closed (P < 0.05). Whereas intervention intensity had a non-significant moderating effect in the open skills intervention, both moderate and vigorous intensity had a significant effect on executive function (P < 0.001).

CONCLUSION

Open and closed skills have different levels of facilitation effects on executive function in typical children, but open skills are more effective. The facilitation effects of open and closed skills were moderated by the qualitative characteristics and action structure of the intervention.

The influence of physical education courses integrated with civic education on prosocial behavior among college students: the chain mediating effect of cultural confidence and self-esteem

Objective

This study sought to uncover the relationship between physical education courses integrated with civic education (PECICE) and prosocial behavior among university students. Additionally, we aimed to decipher the mediating roles of cultural confidence and self-esteem within this relationship.

Methods

Employing a questionnaire-based approach, we assessed the relationship among PECICE, cultural confidence, self-esteem, and prosocial behavior in university students. The instrument comprised four distinct scales: the Perceived Effectiveness Scale for PECICE, the Cultural Confidence Scale, the Self-Esteem Scale, and the Prosocial Behavior Scale. Our sample encompassed 293 Chinese college students, consisting of 137 men and 156 women, with an average age of 21.39 years (SD = 2.1).

Results

PECICE demonstrated significant positive associations with cultural confidence (r = 0.29, p < 0.001), self-esteem (r = 0.35, p < 0.001), and prosocial behavior (r = 0.40, p < 0.001). The influence of PECICE on prosocial behavior among university students was mediated through three channels: solely via cultural confidence (mediating effect value: 0.14), solely via self-esteem (mediating effect value: 0.22), and through the combined influence of both cultural confidence and self-esteem (mediating effect value: 0.2).

Conclusion

The intertwined mediating roles of cultural confidence and self-esteem highlight their pivotal significance in enhancing the efficacy of PECICE. These insights offer a valuable reference for both educators and policymakers striving to augment prosocial behavior in university students.

Association Between Daily Physical Education Attendance and Meeting 24-Hour Movement Guidelines in Adolescence and Adulthood

PURPOSE

To investigate the relationship between participation in physical education lessons (PELs), i.e., minutes or frequency per week, and meeting the 24-hour movement guidelines (i.e., physical activity, screen time, and sleep duration) during adolescence (12-17 years old) and adulthood (33-39 years old).

METHODS

We analyzed data from individuals who participated in Waves I (1994-1995) and V (2016-2018) of the National Longitudinal Study of Adolescent Health. We determined total weekly minutes of PELs and PELs participation by asking how many days adolescents attended PELs in an average week at school, with three possible responses as follows: 0, 1-4, or 5 days/week. Movement behaviors were assessed through self-completed questionnaires in both waves.

RESULTS

Daily PELs participation during adolescence was related to higher odds of meeting five of more weekly sessions of moderate-to-vigorous physical activity and all three guidelines in both sexes compared with adolescents who reported no days of PELs per week (men: incidence rate ratio [IRR] = 1.70, 95% CI 1.02-3.12; women: IRR = 3.81, 95% CI 1.65-8.77). Additionally, each additional weekly hour of PELs increased the likelihood of meeting all three recommendations (men: IRR = 1.11, 95% CI 1.05-1.35; women: IRR = 1.67, 95% CI 1.27-2.24). During adulthood, daily PELs was also related to a higher likelihood of meeting all three recommendations in both sexes (men: IRR = 1.04, 95% CI 1.01-1.07; women: IRR = 1.07, 95% CI 1.00-1.11). Each additional weekly hour of PELs increased the odds of meeting all three recommendations (men: IRR = 1.02, 95% CI 1.01-1.05; women: IRR = 1.03, 95% CI 1.01-1.06).

DISCUSSION

Daily PELs attendance was linked to healthy movement behaviors during adolescence, and these benefits could extend into adulthood.

Effects of Resistance Training on Academic Outcomes in School-Aged Youth: A Systematic Review and Meta-Analysis

BACKGROUND

The primary aim of our systematic review and meta-analysis was to investigate the effect of resistance training on academic outcomes in school-aged youth.

METHODS

We conducted a systematic search of six electronic databases (CINAHL Complete, PsycINFO, SCOPUS, Ovid MEDLINE, SPORTDiscus and EMBASE) with no date restrictions. Studies were eligible if they: (a) included school-aged youth (5-18 years), and (b) examined the effect of resistance training on academic outcomes (i.e., cognitive function, academic achievement, and/or on-task behaviour in the classroom). Risk of bias was assessed using the appropriate Cochrane Risk of Bias Tools, funnel plots and Egger's regression asymmetry tests. A structural equation modelling approach was used to conduct the meta-analysis.

RESULTS

Fifty-three studies were included in our systematic review. Participation in resistance training (ten studies with 53 effect sizes) had a small positive effect on the overall cognitive, academic and on-task behaviours in school-aged youth (standardized mean difference (SMD) 0.19, 95% confidence interval (CI) 0.05-0.32). Resistance training was more effective (SMD 0.26, 95% CI 0.10-0.42) than concurrent training, i.e., the combination of resistance training and aerobic training (SMD 0.11, 95% CI - 0.05-0.28). An additional 43 studies (including 211 effect sizes) examined the association between muscular fitness and cognition or academic achievement, also yielding a positive relationship (SMD 0.13, 95% CI 0.10-0.16).

CONCLUSION

This review provides preliminary evidence that resistance training may improve cognitive function, academic performance, and on-task behaviours in school-aged youth.

Are active school transport and leisure-time physical activity associated with performance and wellbeing at secondary school? A population-based study

BACKGROUND

Physically active pupils may be better and more resilient learners. However, it is unclear whether walking or cycling to school yields similar educational and school-related mental health benefits as leisure-time physical activity. We examined the associations of active school transport and leisure-time moderate-to-vigorous physical activity with perceived academic performance, competency in academic skills, school burnout and school enjoyment.

METHODS

We included 34 103 Finnish adolescents (mean age 15.4 years; 53% girls) from the 2015 School Health Promotion study cohort. For the analyses, we used logistic regression, adjusting for major sociodemographic, environmental, lifestyle and physical activity covariates.

RESULTS

Active school transport was positively associated with educational outcomes and school enjoyment, but not with school burnout. For example, compared with non-active transport, 10-30 min of daily active school transport was linked to 30% [odds ratio (OR) 1.30, 95% confidence interval (CI) 1.21-1.40] and 17% (OR 1.17, 95% CI 1.08-1.27) higher odds of high perceived academic performance and high reading competency, respectively. Leisure-time physical activity was robustly associated with all outcomes. For example, compared with the inactive, the most physically active adolescents had 86% higher odds of high perceived academic performance (OR 1.86, 95% CI 1.66-2.08), 57% higher odds of high competency in mathematics (OR 1.57, 95% CI 1.39-1.77) and 40% lower odds of school burnout (OR 0.60, 95% CI 0.52-0.69).

CONCLUSIONS

Compared with active school transport, leisure-time physical activity was more strongly associated with educational and school-related mental health outcomes. Nevertheless, walking or cycling to school might lead to improvements in classroom performance and school enjoyment.

Are more physical education classes related to less time in leisure-time sedentary behavior? An analysis including adolescents from 73 countries

This study aimed to verify the association between the weekly frequency of physical education (PE) classes and leisure sitting time among adolescents. We analyzed data from 73 countries using the Global School-based Student Health Survey (283,233 adolescents between 11 and 18 years of age). Leisure sitting time and weekly frequency of PE classes were self-reported. Sex, age, and food insecurity were used as covariates and the analyses were stratified by world regions and country income level. Poisson regression models (random-effects meta-analysis) were used for the main analyses. In comparison with 1 PE class per week (reference group), those with no PE classes presented a lower prevalence of ≥ 3 h/d of leisure sitting time (PR [95%CI] = 0.94 [0.91; 0.98]). On the other hand, adolescents with 2 days (PR [95%CI] = 1.06 [1.02; 1.26]), 3-4 days (PR [95%CI] = 1.17 [1.12; 1.22]), and 5 days (PR [95%CI] = 1.08 [1.04; 1.11]) of PE classes presented a higher likelihood of ≥ 3 h/d of leisure sitting time. No clear differences were observed for the different world regions and country income levels. We conclude that a higher weekly frequency of PE classes is associated with increased leisure sitting time among adolescents worldwide.

Facilitators and barriers to physical activity among English adolescents in secondary schools: a mixed method study

Background

It is evident that physical activity (PA) programmes implemented in schools were not effective in improving PA behaviours among adolescents. This study investigated students' perceptions of barriers to PA among inactive English adolescents in secondary schools based on the Capability, Opportunity, Motivation, and Behaviour (COM-B) model, the Behaviour Change Wheel (BCW), and Theoretical Domains Framework (TDF). The study compared barriers faced by inactive and active groups participating in sports and PA in secondary schools to identify sources of behaviour contributing to inactivity.

Methods

A pre-intervention online survey was distributed to affiliated schools by 233 Teaching Schools Alliances (TSAs) as part of the monitoring and evaluation of the Secondary Teacher Training study. Data were cross-tabulated to analyse activity levels and behavioural barriers for active and inactive groups, using the COM-B domains. The research team followed a seven-step process to categorise barriers based on their relevant domain in the TDF mapped to the COM-B.

Results

The findings were derived from one of the most extensive surveys of adolescents ever undertaken involving 200,623 active and 8,231 inactive respondents. The study identified 52 barriers and 68 behaviours that prevent adolescents from participating in PA. Psychological and social barriers were found to affect all activity levels, genders, and ethnic groups, with a lack of confidence and self-consciousness being the most prevalent. Certain demographic groups, such as those from minority ethnic groups and disabled individuals, were found to be overrepresented among inactive populations. The finding of the study indicated that there were common barriers that affected both inactive and active groups, with further similarity when examining barriers between active and inactive girls. The study also found that girls were more likely to experience the main barriers compared to boys, while inactive boys were more likely to encounter these barriers compared to active boys. The findings suggest that common barriers could be addressed across the population, while recognising some differences in demographics, and the need to provide personalised support. Targeted interventions are also suggested for all girls and inactive boys.

Conclusion

This study highlights the range of barriers that impact adolescents and provides insight into potential mechanisms for behaviour change, including intervention functions, policy categories, and evidence-based behaviour change tools. The study highlights the need for further research to address the barriers to PA among adolescents, particularly those who are inactive. Utilising the findings of this study, future research should investigate the effectiveness of novel digital exercise interventions and policies in increasing PA levels among children and adolescents. Complex digital exercise interventions, including conversational AI solutions, could provide personalised tools to identify and revolutionise support around the multitude of barriers that impact adolescents globally."For the purpose of open access, the author has applied a Creative Commons Attribution (CC BY) licence to any Author Accepted Manuscript version arising from this submission."

Effect of physical activity interventions on children's academic performance: a systematic review and meta-analysis

The physical and psychological benefits of physical activity are well established. However, there is no consensus regarding the effects of physical activity on children's academic performance in general and in specific subjects. We conducted this systematic review and meta-analysis to identify forms of physical activity that are suitable for improving the physical activity levels and academic performance of children aged 12 years and under. The PubMed, Web of Science, Embase, and Cochrane Library databases were searched. Included studies had to meet the following criteria: randomized controlled trials examining the effect of physical activity interventions on children's academic performance. Stata 15.1 software was used to conduct the meta-analysis. A total of 16 studies were included, and the results showed that the "physical activity + academic curriculum" format had a positive effect on children's academic performance. Physical activity had a stronger effect on math performance than on reading and spelling performance (SMD = 0.75, 95% CI: 0.30,1.19, P < 0.001).   Conclusion: The impact of physical activity on children's academic performance varies based on the type of physical activity intervention, with "physical activity + academic curriculum" format having a better effect on academic performance. The effect of physical activity interventions on children's academic performance also varies by subject; the effect is strongest for math.    Trial registration: Registration and protocol CRD42022363255. What is Known: • The physical and psychological benefits of physical activity are well established. • Previous meta-analyses have failed to demonstrate the impact of physical activity on the general and subject-specific academic performance of children aged 12 and under. What is New: • The PAAL form of physical activity has a better effect on the academic performance of children aged 12 and under. • The benefit of physical activity also varies by subject, with the greatest effect being observed for math.

Interventions to Address Cardiovascular Risk in Obese Patients: Many Hands Make Light Work

Obesity is a growing public health epidemic worldwide and is implicated in slowing improved life expectancy and increasing cardiovascular (CV) risk; indeed, several obesity-related mechanisms drive structural, functional, humoral, and hemodynamic heart alterations. On the other hand, obesity may indirectly cause CV disease, mediated through different obesity-associated comorbidities. Diet and physical activity are key points in preventing CV disease and reducing CV risk; however, these strategies alone are not always sufficient, so other approaches, such as pharmacological treatments and bariatric surgery, must support them. Moreover, these strategies are associated with improved CV risk factors and effectively reduce the incidence of death and CV events such as myocardial infarction and stroke; consequently, an individualized care plan with a multidisciplinary approach is recommended. More precisely, this review explores several interventions (diet, physical activity, pharmacological and surgical treatments) to address CV risk in obese patients and emphasizes the importance of adherence to treatments.

Barriers and facilitators to physical activity and further digital exercise intervention among inactive British adolescents in secondary schools: a qualitative study with physical education teachers

Background

Previous studies indicated that physical education programs in schools were unsuccessful to ameliorate physical activity (PA) behaviors among adolescents. This study investigated PE teachers' perceptions of barriers and facilitators to PA and further digital exercise interventions among inactive British adolescents in secondary schools based on the Capability, Opportunity, Motivation, and Behavior (COM-B) model, the Behavior Change Wheel (BCW), and Theoretical Domains Framework (TDF).

Method

A qualitative study was conducted among 156 PE teachers in England. deductive thematic analysis approach was applied to analyze data.

Results

A comprehensive perception of PE teachers revealed 21 barriers to PA among inactive adolescents in secondary schools. The study findings show that barriers exist across all categories of the COM-B model in physical opportunity (7), reflective motivation (5), social opportunity (4), psychological capability (4) and physical capability (1). The majority of these barriers were reported in previous studies as being barriers to PA from the perspective of children and adolescents. This shows that the findings are consistent with the views of children and adolescents that participated in these studies. Particular salient barriers for inactive adolescents were reported and greater insight into their experiences was highlighted. The study reported the main sources of behavior, intervention functions, policy functions, and behavior change tools that can be used for future behavior change interventions to support inactive adolescents.

Conclusion

The study recommends using its findings to design interventions for inactive adolescents to achieve recommended levels of physical activity (PA). The study's comprehensive approach and evidence-based solutions provide extensive reference points for future intervention design, informing policy and contributing to enhancing support for inactive adolescents. Further development of digital exercise interventions, including conversational artificial intelligence (AI), is suggested to engage adolescents at scale and provide personalized support to overcome multiple barriers to PA.

The Perception of Volleyball Student-Athletes: Evaluation of Well-Being, Sport Workload, Players' Response, and Academic Demands

Physical activity has been shown to improve the health and well-being of students, athletes and the general population, especially when it is properly monitored and responses are evaluated. However, data are mostly gathered without considering a valuable element, participants' perceptions. Therefore, the objective was to know the perception of volleyball student-athletes when using different monitoring and response tools that assess well-being, workloads, responses to workloads, and academic demands. A qualitative study using semi-structured interviews with female volleyball student-athletes (n = 22) was used to know players' perceptions when using a wellness/well-being questionnaire, session ratings of perceived exertion (sRPE), and countermovement jumps (CMJ), and consider academic demands. Results show that the wellness questionnaire and sRPE increased student-athletes' awareness of well-being and readiness to perform, improved self-evaluation, self-regulation, and self-demand. However, motivation and overcoming challenges were based on the CMJ. Academic demands affected 82% of student-athletes, altering stress, fatigue, and sleep quality. Nonetheless, sport was seen as an activity that helped with academic commitments. Therefore, the wellness questionnaires and the sRPE facilitated self-awareness and positive dispositions toward self-regulation. Simultaneous intensive academic demands and training can produce mutual positive effects if the variables of physical and mental loads are harmonized in the critical academic and sports periods.

The Effects of Cognitively Challenging Physical Activity Games versus Health-Related Fitness Activities on Students' Executive Functions and Situational Interest in Physical Education: A Group-Randomized Controlled Trial

This study compared cognitively challenging physical activity games and health-related fitness activities in terms of their effects on students' executive functions and situational interest in physical education. A total of 102 fourth- and fifth-grade students (56 boys, 46 girls) participated in this study. A group-randomized controlled trial design involving an acute experiment was used. Two intact classes of students (one fourth-grade and one fifth-grade) were randomly assigned to each one of the three groups. Students in Group 1 participated in cognitively challenging physical activity games, students in Group 2 participated in activities for developing their health-related fitness, and Group 3 students were the control group without physical education. Executive functions were measured pre- and post-intervention with the design fluency test, whereas situational interest was only measured post-intervention with the situational interest scale. Group 1 students who played cognitively challenging physical activity games had increased their executive functions' scores more than the Group 2 students involved in health-related fitness activities. Students of both these groups outperformed control group students. Moreover, Group 1 students reported higher levels of instant enjoyment and total interest than Group 2 students. The results of this study suggest that cognitively challenging physical activity games can be an effective means for enhancing executive functions, and motivate students to be involved in interesting and enjoyable forms of physical activity.

Cross-cultural adaptation, reliability, and validation of the Spanish perceived physical literacy instrument for adolescents (S-PPLI)

Objective

The aim of this study was to examine the reliability and validity of the Spanish Perceived Physical Literacy Instrument (S-PPLI) questionnaire in Spanish adolescents.

Method

The participants of this study were 360 Spanish adolescents (aged 12-17 years) from three secondary schools in the Region of Murcia (Spain). A cultural adaptation process of the original version of the PPLI questionnaire was developed. Confirmatory factor analysis was applied to test the three-factor structure of physical literacy. Intraclass correlation coefficients were computed to estimate the test-retest concordance.

Results

Using a confirmatory factor analysis, the factor loading of all items above the standard of 0.40 ranged from 0.53 to 0.77, suggesting that the observed variables sufficiently represented the latent variables. Analyses for convergent validity showed average variance extracted values that ranged from 0.40 to 0.52 and composite reliability values higher than 0.60. All the correlations were below the recommended cutoff point of 0.85, which indicated that the three physical literacy factors achieved adequate discriminant validity. Intraclass correlation coefficients ranged from 0.62 to 0.79 (p < 0.001 for all items), which indicated moderate/good reliability.

Conclusions

Our results suggest that the S-PPLI is a valid and reliable measure of physical literacy among Spanish adolescents.

Effects of a games-based physical education lesson on cognitive function in adolescents

Despite the importance of physical education (PE) lessons for physical activity in adolescents, the acute cognitive responses to PE lessons have not been explored; a gap in the literature that this study addresses. Following familiarisation, 76 (39 female) adolescents (12.2 ± 0.4 y) completed two trials (60 min games-based PE lesson and 60 min academic lesson) separated by 7-d in a counterbalanced, crossover design. Attention, executive function, working memory, and perception were assessed 30 min before, immediately post, and 45 min post-lesson in both trials. Participants were split into high-and low-fit groups based on a gender-specific median split of distance run on the multi-stage fitness test. Furthermore, participants were split into high and low MVPA groups based on a gender-specific median split of MVPA time (time spent &gt;64% HR max) during the PE lesson. Overall, a 60 min games-based PE lesson had no effect on perception, working memory, attention, or executive function in adolescents (all p &gt; 0.05) unless MVPA time is high. The physical activity-cognition relationship was moderated by MVPA, as working memory improved post-PE lesson in adolescents who completed more MVPA during their PE lesson (time*trial*MVPA interaction, p &lt; 0.05, partial η2 = 0.119). Furthermore, high-fit adolescents displayed superior cognitive function than their low-fit counterparts, across all domains of cognitive function (main effect of fitness, all p &lt; 0.05, partial η2 0.014–0.121). This study provides novel evidence that MVPA time moderates the cognitive response to a games-based PE lesson; and emphasises that higher levels of fitness are beneficial for cognitive function in adolescents.

News of the Pedagogical Models in Physical Education-A Quick Review

In the last two decades, research has proliferated in the field of pedagogical models used in school Physical Education. The growth is so high that it is necessary to do a quick review to know which models currently exist and which are emerging. The objective of this work is to collect all the models or pedagogical approaches present in the scientific literature related to school Physical Education and to make known, to the scientific and academic community, its main purposes and characteristics. A quick review of the literature found in the Web of Science and Scopus databases has been carried out using "pedagogical model" and "Physical Education" as descriptors. The results revealed a total of 19 pedagogical approaches that record scientific evidence linked to their application in the classroom. It was detected that some models or approaches were more scientifically supported than others, as is the case for Cooperative Learning, Sports Education, or Teaching Games for Understanding, while others barely registered in international scientific literature. It was concluded that researchers need to work together with Physical Education teachers to analyze the effectiveness of all these approaches. School teachers are also encouraged to vary their pedagogical approach depending on the content they are working on and the positive effects they are looking for in the psychic, motor, affective-emotional, and social domains of the students. Finally, it is proposed to researchers who promote new models or approaches a greater clarity of these to facilitate their application in the field of school Physical Education, since some difficulty has been detected in the practical application of some approaches.

Physical activity and exercise for cancer-related cognitive impairment among individuals affected by childhood cancer: a systematic review and meta-analysis

BACKGROUND

Individuals affected by childhood cancer can have cognitive dysfunction that persists into adulthood and negatively affects quality of life. In this study, we aimed to evaluate the effects of physical activity and exercise on cognitive function among individuals affected by childhood cancer.

METHODS

In this systematic review and meta-analysis, we searched seven databases (CINAHL Plus, Cochrane Library, Embase, MEDLINE, PsycINFO, SPORTDiscus, and Web of Science) and two clinical trial registries (ClinicalTrials.gov and the International Clinical Trials Registry Platform) for randomised controlled trials (RCTs) and non-randomised studies of interventions (NRSIs) published (or registered) from database inception to Jan 30, 2022, with no language restrictions. We included studies that compared the effects of physical activity or exercise interventions with controls (no intervention or usual care) on cognitive function among individuals diagnosed with any type of cancer at age 0-19 years. Two reviewers (JDKB and FR) independently screened records for eligibility and searched references of the selected studies; extracted study-level data from published reports; and assessed study risk of bias of RCTs and NRSIs using the Cochrane risk of bias tool for randomised trials (RoB 2) and Risk Of Bias In Non-randomised Studies-of Interventions (ROBINS-I) tools, certainty of the evidence using the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) approach, and any adverse events. We used intention-to-treat data and unpublished data if available. Cognitive function was assessed by standardised cognitive performance measures (primary outcome) and by validated patient-reported measures (secondary outcome). A random-effects meta-analysis model using the inverse-variance and Hartung-Knapp methods was used to calculate pooled estimates (Hedges' g) and 95% CI values. We estimated the heterogeneity variance by the restricted maximum likelihood method and calculated I² values to measure heterogeneity. We examined funnel plots and used Egger's regression test to assess for publication bias. This study is registered with PROSPERO, CRD42021261061.

FINDINGS

We screened 12 425 titles and abstracts, which resulted in full-text assessment of 131 potentially relevant reports. We evaluated 22 unique studies (16 RCTs and six NRSIs) with data on 1277 individuals affected by childhood cancer and low-to-moderate risk of bias. Of the 1277 individuals, 674 [52·8%] were male and 603 [47·2%] were female; median age at study start was 12 (IQR 11-14) years, median time since the end of cancer treatment was 2·5 (IQR -1·1 to 3·0) years, and median intervention period was 12 [IQR 10-24] weeks. There was moderate-quality evidence that, compared with control, physical activity and exercise improved cognitive performance measures (five RCTs; Hedges' g 0·40 [95% CI 0·07-0·73], p=0·027; I²=18%) and patient-reported measures of cognitive function (13 RCTs; Hedges' g 0·26 [0·09-0·43], p=0·0070; I²=40%). No evidence of publication bias was found. Nine mild adverse events were reported.

INTERPRETATION

There is moderate-certainty evidence that physical activity and exercise improves cognitive function among individuals affected by childhood cancer, which supports the use of physical activity for managing cancer-related cognitive impairment.

The association between meeting physical activity guidelines and academic performance among junior high school adolescents in China-evidence from the China education tracking survey

Purpose

To examine how well Chinese adolescents meet the physical exercise time and screen time recommendations in the Physical Activity Guidelines for Chinese Residents (2021), and the relationship between adolescents' physical exercise time, screen time and their academic performance.

Method

Daily physical exercise time, screen time and academic performance were collected from Grade 8 adolescents (n = 9,449). Academic performance included standardized scores on Chinese, Math and English tests and responses to the School Life Experience Scale.

Results

Meeting the physical activity time and screen time in the Physical Activity Guidelines for Chinese Residents was associated with adolescents' academic performance. Specifically, having at least 60 min of physical exercise per day was associated with adolescents' school life experiences compared to adolescents who did not meet the physical exercise time and screen time in the Chinese Residents' Physical Activity Guidelines. Less than 2  h of cumulative screen time per day was associated with adolescent mathematics test scores, English test scores and school life experiences. Meeting both physical exercise time and screen time to be recommended had more significant effects on adolescents' mathematics, Chinese, English and school life experiences. Meeting both the physical exercise time and screen time recommendations in the Physical Activity Guidelines for Chinese Residents was more significantly associated with boys' mathematics test scores, Chinese test scores and School life experience. Meeting both the physical exercise time and screen time requirements in the Physical Activity Guidelines for Chinese Residents had a more significant effect on School life experience for girls.

Conclusion

Physical exercise participation of at least 60 min per day and/or less than 2  h of cumulative screen time per day were both associated with adolescent academic performance. Stakeholders should actively promote adolescents to follow the Physical Activity Guidelines for Chinese Residents (2021).

Motor skills and cognitive benefits in children and adolescents: Relationship, mechanism and perspectives

OBJECTIVE

There is a strong interaction between motor skills and cognitive benefits for children and young people. The aim of this paper is to explore the relationship between motor skill types and their development and the cognitive benefits of children and adolescents. In turn, on this basis, it proposes pathways and mechanisms by which motor skills improve cognition, and provide a basis for subsequent teaching of skills that follow the laws of brain cognitive development.

METHODS

This paper summarizes the research on the relationship between different types of motor skills and their development and cognitive benefits of children and adolescents. Based on these relationships, pathways, and mechanisms for motor skills to improve cognition are tentatively proposed.

RESULTS

There is an overall pattern of "open > closed, strategy > interception, sequence > continuous" between motor skill types and the cognitive benefits of children and adolescents. Long-term motor skill learning practice is accompanied by increased cognitive benefits as skill proficiency increases. The dynamic interaction between motor skills and physical activity exposes children and adolescents to environmental stimuli and interpersonal interactions of varying complexity, promoting the development of agility, coordination and cardiorespiratory fitness, enhancing their motor experience, which in turn improves brain structure and functional activity.

CONCLUSION

Motor skills training promote cognitive efficiency in children and adolescents. Motor skill interventions that are open-ended, strategic and sequential in nature are more effective. Environmental stimuli, interpersonal interaction, agility, coordination, and cardiorespiratory fitness can be considered as skill attribute moderators of motor skills to improve cognition.

The Effects of a Cognitively Challenging Physical Activity Intervention on School Children's Executive Functions and Motivational Regulations

This study examined the effects of a physical education intervention consisting of cognitively challenging physical activity games on school children's executive functions and motivational regulations. Ninety-nine fourth- and fifth-grade children participated in this two-group, repeated measures, quasi-experimental study with a cross-over design. Children's executive functions (measured with the design fluency and Stroop and flanker tests) and motivational regulations were measured pre- and post-intervention and one month later. At post-test, the experimental group children outperformed the waiting-list control group children in all design fluency test conditions and accuracy in the Stroop and flanker tests. Both groups improved from pre- to post-intervention their speed (reaction time) in the Stroop and flanker tests. The waiting-list control group children, after receiving the intervention, improved their performance in the executive function tests except for Stroop test accuracy and flanker test speed. The positive effects were reduced significantly one month after the end of the intervention but remained significantly higher compared to pre-intervention. No intervention effects were found for the motivational regulations. These results showed that the intervention had positive effects on children's executive functions and supported the new shift of designing physical activity programs for developing combinedly children's physical and cognitive development.

Global Matrix 4.0 physical activity report cards grades for children and adolescents: A comparison among 15 Asian countries and regions

Background

/Objective: This paper aimed to compare the report card grades among 15 Asian jurisdictions participating in the Global Matrix 4.0, and to explore differences in regional cultural and policy factors related to physical activity behaviors.

Methods

All participating jurisdictions followed a harmonized process to develop a country report card. Ten required common indicators were assessed, including five behavioral indicators (Overall Physical Activity, Organized Sport and Physical Activity, Active Play, Active Transportation, Sedentary Behavior), four sources of influence indicators (Family and Peers, School, Community and Environment, and Government), and an outcome indicator (Physical Fitness). Letter grades, ranging from A+ to F or incomplete (INC), were assigned to the indicators based on the predefined benchmarks and grading rubric, and were converted to numerical scale for analyses.

Results

The country average scores ranged from F (Indonesia) to B- (Japan), with C+/C/C- the most prevalent grades. The mean behavioral score (D+) was lower than sources of influence score (C+). Poor grades (D or F) were observed for Overall Physical Activity among 73.3% (11/15) of the jurisdictions. Government was the indicator with the highest proportion of A or B grades (66.7%), followed by School (53.3%). Physical Fitness (n = 10) and Active Play (n = 8) were two indicators with the largest number of INC grades.

Conclusions

Poor grades for physical activity and sedentary behavior were generally found in Asian jurisdictions. The better, though modest, grades on the sources of influence have not been translated into favorable behaviors among children and adolescents. The findings also suggested surveillance gaps for physical fitness, active play, and organized sport participation. National-level investments and action plans are needed to ensure physical activity interventions are developed, effectively implemented, and regularly evaluated in multiple settings.

Ringing the bell for quality P.E.: What are the realities of remote physical education?

BACKGROUND

To date, few data on the quality and quantity of online physical education (P.E.) during the COVID-19 pandemic have been published. We assessed activity in online classes and reported allocated curriculum time for P.E. in a multi-national sample of European children (6-18 years).

METHODS

Data from two online surveys were analysed. A total of 8395 children were included in the first round (May-June 2020) and 24 302 in the second round (January-February 2021).

RESULTS

Activity levels during P.E. classes were low in spring 2020, particularly among the youngest children and in certain countries. 27.9% of students did not do any online P.E. and 15.7% were hardly ever very active. Only 18.4% were always very active and 14.9% reported being very active quite often. In winter 2020, we observed a large variability in the allocated curriculum time for P.E. In many countries, this was lower than the compulsory requirements. Only 65.7% of respondents had the same number of P.E. lessons than before pandemic, while 23.8% had less P.E., and 6.8% claimed to have no P.E. lessons. Rates for no P.E. were especially high among secondary school students, and in large cities and megapolises.

CONCLUSIONS

During the COVID-19 pandemic, European children were provided much less P.E. in quantity and quality than before the pandemic. Countermeasures are needed to ensure that these changes do not become permanent. Particular attention is needed in large cities and megapolises. The critical role of P.E. for students' health and development must be strengthened in the school system.

Physical exercise ameliorates memory impairment in offspring of old mice

For humans, maternal old age means the age of 35 or older at the time of childbirth. Maternal metabolism not only affects the cognitive function of the offspring, but also affects their physical and neurological development. This study aims to elucidate the effects of exercise training on spatial learning memory, neurogenesis, and apoptosis in the off-spring of old mice. Using mice, the offspring of old mothers showed impaired spatial learning memory, decreased brain-derived neurotrophic factor and postsynaptic density protein 95 levels, suppressed neurogenesis, and increased hippocampal apoptotic cell death. In contrast, the offspring of the old mothers had improved spatial learning memory, increased brain-derived neurotrophic factor and postsynaptic density protein 95 levels, increased neurogenesis, and decreased hippocampal apoptotic cell death when they received exercise training. The present results indicate that there is apparent spatial learning memory impairment among the offspring of old mothers, but by contrast, exercise can ameliorate spatial learning memory impairment. Exercise can be an effective countermeasure against memory decline in the offspring of old mothers.

What Drives Quality Physical Education? A Systematic Review and Meta-Analysis of Learning and Development Effects From Physical Education-Based Interventions

Objective

To determine the effects of learning interventions aimed at optimizing the quality of physical education (PE) on psychomotor, cognitive, affective and social learning outcomes in children and adolescents.

Design

A systematic review and meta-analysis.

Data Sources

After searching PsycInfo, ERIC, and SportDiscus electronic databases, we identified 135 eligible studies published between January 1, 1995 to May 1, 2021.

Eligibility Criteria for Selecting Studies

We included randomized controlled trials, quasi-experimental studies, and controlled trials that assessed the effect of a PE-based intervention against one of the four identified learning domains in youth at school (aged 5–18 years).

Results

One hundred and thirty five (135) studies with over 42,500 participants and 193 calculated effect sizes were included in the study. The mean effect across all the learning and development outcomes was small to medium (Cohen's d = 0.32, 95% confidence interval [CI] (0.27–0.37). When adjusted for publication bias using the Duval and Tweedie Trim and Fill Method, this mean effect size increased to d = 0.40 (CI = 0.34–0.46). Effect sizes varied significantly based on learning and development outcomes. Interventions that consistently report above or below the mean d = 0.40 effect are identified based on learning outcome. The greatest effects across interventions were witnessed in psychomotor learning outcomes (d = 0.52) followed by affective (d = 0.47), social (d = 0.32), and cognitive (d = 0.17) learning outcomes. A minority (&lt;10%) of PE interventions captured by this systematic review and meta-analysis reported having a negative effect on student learning and development.

Conclusion

The interventions with the greatest effects on student learning and development were dependant on the learning domains. Some PE interventions with a pedagogical focus such as games-based approaches, TARGET/Mastery Teaching, and Sport Education were found to be strong investments across multiple domains. The evidence is limited however by consistency in intervention dosage, study design, and data collection instruments. The study received no internal or external funding and was not prospectively registered.

The Impact of the Daily Mile™ on School Pupils' Fitness, Cognition, and Wellbeing: Findings From Longer Term Participation

Background

School based running programmes, such as The Daily Mile™, positively impact pupils' physical health, however, there is limited evidence on psychological health. Additionally, current evidence is mostly limited to examining the acute impact. The present study examined the longer term impact of running programmes on pupil cognition, wellbeing, and fitness.

Method

Data from 6,908 school pupils (mean age 10.2 ± 0.7 years), who were participating in a citizen science project, was examined. Class teachers provided information about participation in school based running programmes. Participants completed computer-based tasks of inhibition, verbal and visual-spatial working memory, as well as the Children's Feeling scale and Felt arousal scale to determine subjective wellbeing. A multistage 20-m shuttle run test was used to estimate fitness.

Results

From our total sample of 6,908 school pupils, 474 participants had been taking part in a running programme for <2 months (Shorter term participation); 1,004 participants had Longer Term participation (>3 months); and 5,430 did not take part in a running programme. The Longer Term participation group had higher fitness levels than both other groups and this remained significant when adjusted for age, sex and SES. Moderated regression analysis found that for the Shorter Term participation group, higher shuttle distance was associated with better visual-spatial working memory. Effect sizes were small though.

Conclusion

We identified small and selective positive impact of participation in school based running programmes on fitness and cognition. While no long term benefit was identified for cognition or wellbeing, the impact on fitness and short term benefit suggest schools should consider participation.

A Sustainable Swedish School Intervention with Extra Aerobic Exercise—Its Organization and Effects on Physical Fitness and Academic Achievement

A large majority of Swedish children do not reach the recommended daily activity level. Some, but not all, studies show that extra physical activity may have positive effects on children’s school performance, physical fitness and health. The present purpose was to offer pupils from the 7th to the 8th grade extra aerobic exercise led by physical education teachers and to evaluate the effects on aerobic fitness, muscle strength, school grades and health. The hypothesis was that extra aerobic exercise would improve physical fitness, school grades and health. In the two-year project, 122 pupils aged 13–14 years from three schools constituted an aerobic group with 30 min extra exercise sessions (≥70% maximal heart rate) twice weekly. A control group of 26 pupils was included. All 148 pupils also had regular 60 min physical education lessons (2/week). A moderate to large significant effect size (via partial eta-squared) of the interaction effect for the aerobic group compared to the control group over time was generally seen for aerobic fitness, the muscle strength test with push-ups, school grades in Swedish, English and physical education, and in average school grade for four school subjects combined, thus also including mathematics. Within the aerobic group, significant improvements were also shown for aerobic fitness, endurance and strength of abdominal and leg muscles, and the total physical test index during the two-year project. The control group showed no corresponding improvement in these parameters. Improvements in school grades were generally seen among both sexes in the aerobic group, whereas improvements in physical capacity were distinctly more pronounced among boys and seldom among girls. A similar pattern with significant improvement in several school grades was noted in all three intervention schools, although one of the schools had a distinctly larger proportion of children who immigrated to Sweden. The aerobic group showed significantly higher ratings (with a small to moderate effect size) on several questions about physical self-perception than the control group at the end of the 8th grade. This teacher-led school intervention generated a sustainable project with improvements in physical fitness and school grades. The project might act as an inspiration for other schools to increase physical activity to improve physical fitness and possibly school grades.

Can Primary School Mathematics Performance Be Predicted by Longitudinal Changes in Physical Fitness and Activity Indicators?

Objective

To determine to what extent physical fitness indicators and/or moderate to vigorous physical activity (MVPA) may account for final mathematics academic performance (AP_math) awarded at the end of primary school.

Methods

School-aged youth were sampled in a repeated-measures, longitudinal design in Grade 6 (∼11 years), and again in Grade 9 (∼14 years). The youth (N = 231, 111 girls) completed a fitness test battery consisting of: flamingo balance test, standing long jump, backward obstacle course, plate tapping, sit ups, sit and reach, handgrip, and 20-m shuttle run. AP_math scores were obtained for all children at the end of Grade 5, end of Grade 8, and end of Grade 9 (their final year of primary school). In a sub-sample of Grade 6 youth (N = 50, 29 girls), MVPA was measured objectively via SenseWear Pro Armbands (MVPA_OB) for seven consecutive days, with measurements repeated in Grade 9.

Results

Math scores decreased from Grade 6 to 9 for both boys and girls (95%CI: −0.89 to −0.53, p < 0.001). MVPA_OB was reduced by ∼45.7 min (−33%) from Grade 6 to 9 (p < 0.01). Significant main and interaction effects are noted for each fitness indicator (p < 0.05). A backward stepwise multiple regression analysis determined significant shared variance in final AP_math grade to the change scores from Grade 6 to Grade 9 in: ΔAP_math, Δbackward obstacle course, Δsit and reach, and Δsit-ups [R² = 0.494, F(4,180) = 43.67, p < 0.0001]. A second regression was performed only for the youth who completed MVPA_OB measurements. In this sub-sample, MVPA_OB did not significantly contribute to the model.

Conclusion

Longitudinal changes in youth fitness and their delta change in AP_math score accounted for 49.4% of the variance in the final math grade awarded at the end of Grade 9. Aerobic power, upper body strength, and muscular endurance share more common variance to final math grade in boys, whereas whole-body coordination was the more relevant index in girls; this finding suggests that future research exploring the relationship of AP and PF should not be limited to cardiorespiratory fitness, instead encompassing muscular and neuro-muscular components of PF.

Participation in Physical Education Classes and Health-Related Behaviours among Adolescents from 67 Countries

The present study sought to examine the associations between participation in physical education (PE) classes and a range of health-related behaviours among adolescents. Secondary analysis of self-reported data from the Global Student Health Survey, collected between 2010 and 2017 from 222,121 adolescents (N = 117,914 girls; 49.0%; aged 13–17 years) from 67 countries and five world regions, was carried out. Participation in PE classes (0, 1–2, ≥3 days/week) was the independent variable. Physical activity (PA); sedentary behaviour (SB); active travel to school; fruit, vegetables, and alcohol consumption; and smoking; as well as adopting ≥5 of these healthy behaviours; were the dependent variables. Complex samples logistic regressions were performed to explore the associations between participation in PE classes and health-related behaviours. The results revealed that 18.2% of adolescents did not take part in PE classes. A total of 56.7% and 25.1% of adolescents reported participating in PE classes on 1–2 and ≥3 days/week, respectively. Only 26.8% of adolescents adopted ≥5 healthy behaviours. Participation in PE classes was positively associated with PA, active travel, fruit consumption, and vegetable consumption (only for ≥3 days/week), but was negatively associated with meeting SB recommendations, and with not smoking (only for girls and ≥3 days/week). Overall, PE participation was positively associated with adopting ≥5 healthy behaviours, with favourable results found for those who attended more PE classes. The findings revealed a positive association between participation in PE classes and a range of health-related behaviours among adolescents. This suggests that, worldwide, quality PE should be delivered at least 3 days per week up to daily to promote healthy lifestyles among adolescents.

Motivation and Perceived Motivational Climate by Adolescents in Face-to-Face Physical Education during the COVID-19 Pandemic

The COVID-19 pandemic impacted adolescents’ lives, leading to unprecedented changes in their routines, especially in education. Face-to-face physical education (PE) classes during COVID-19 were affected in organization, possibly conditioning students’ participation, motivation and learning. Based on the achievement goal and self-determination theories, the aim of this study was to analyze and compare the motivational indicators of adolescents in face-to-face PE classes during COVID-19, according to gender, educational level and physical activity (PA). A total of 1369 students participated in the study (621 boys and 748 girls; mean age: 14.4 years; SD: 1.74). Data were collected via an online questionnaire and analyzed using MANCOVAs adjusted for age, pre- and post-COVID-19 PA, socioeconomic status and BMI (Z-score). Differences in achievement goals, motivational climate and motivational regulation levels were found in different groups by gender, PA and educational level, favoring older and more active participants. A more positive motivational profile was found for girls in general and, specifically, for active boys, regarding more self-determined motivations and mastery goal orientations. Overall, this study’s findings suggest that the restrictions related to face-to-face PE classes during the COVID-19 pandemic had a negative impact on students’ motivation.

Differential effects of long-term aerobic versus cognitively-engaging physical activity on children's visuospatial working memory related brain activation: A cluster RCT

Different types of physical activity are thought to differentially affect children's brain activation, via physiological mechanisms, or by activating similar brain areas during physical and cognitive tasks. Despite many behavioral studies relying on these mechanisms, they have been rarely studied. This study looks at both mechanisms simultaneously, by examining effects of two physical activity interventions (aerobic vs. cognitively-engaging) on children's brain activation. Functional Magnetic Resonance Imaging (fMRI) data of 62 children (48.4% boys, mean age 9.2 years) was analyzed. Children's visuospatial working memory related brain activity patterns were tested using a Spatial Span Task before and after the 14-week interventions consisting of four physical education lessons per week. The control group followed their regular program of two lessons per week. Analyses of activation patterns in SPM 12.0 revealed no activation changes between pretest and posttest (p > .05), and no differences between the three conditions in pretest-posttest changes in brain activation (p > .05). Large inter-individual differences were found, suggesting that not every child benefited from the interventions in the same way. To get more insight into the assumed mechanisms, further research is needed to understand whether, when, for whom, and how physical activity results in changed brain activation patterns.

Age and sex effects in physical fitness components of 108,295 third graders including 515 primary schools and 9 cohorts

Children's physical fitness development and related moderating effects of age and sex are well documented, especially boys' and girls' divergence during puberty. The situation might be different during prepuberty. As girls mature approximately two years earlier than boys, we tested a possible convergence of performance with five tests representing four components of physical fitness in a large sample of 108,295 eight-year old third-graders. Within this single prepubertal year of life and irrespective of the test, performance increased linearly with chronological age, and boys outperformed girls to a larger extent in tests requiring muscle mass for successful performance. Tests differed in the magnitude of age effects (gains), but there was no evidence for an interaction between age and sex. Moreover, "physical fitness" of schools correlated at r = 0.48 with their age effect which might imply that "fit schools" promote larger gains; expected secular trends from 2011 to 2019 were replicated.
