Adolescent Sport Participation Research Articles

The key roles of teammates, coaches, and instrumental support in adolescent sports participation: a one-year prospective study.

Sports participation is important for promoting lifelong health and well-being. However, it often declines during adolescence, highlighting the need to understand the factors related to adolescent sports participation. This prospective study examines the associations between different sources (e.g., family, peers, coaches, teachers) and types (e.g., emotional, instrumental, co-participation) of social support and hours of organized sports participation among secondary school students (N = 294). It also explores whether these associations change from the second to the third year of secondary education. Data were collected using questionnaires and anthropometric measurements in October/November 2021 and October/November 2022. Multilevel linear fixed effects regression models were used to analyze relationships between sources and types of social support and sports participation. Additionally, scatterplots illustrated individual variability in these associations. Results showed significant associations for various sources and types of social support with organized sports participation. Social support from teammates and coaches and instrumental support emerged as the strongest predictors of hours of participation. Additionally, we found that the relationships remained stable over time. Yet, substantial individual variability in how social support related to sports participation was also observed. These findings emphasize the importance to promote social support from within the sports environment and to encourage instrumental support. Tailored approaches addressing individual differences are recommended to enhance adolescent sports participation.

Adolescent Sports Participation and Health in Early Adulthood: An Observational Study

We study the impact of teenage sports participation on early-adulthood health using data from the National Study of Youth and Religion. We focus on two primary outcomes measured at ages 23 to 28 (self-rated health and PHQ9 Patient Depression Questionnaire score) and control for several demographic and socioeconomic confounders. To probe the possibility that certain types of sports participation may have larger effects on health than others, we conduct matched observational studies at each level within a hierarchy of exposures. Our hierarchy ranges from broadly defined exposures (e.g., participation in any organized after-school activity) to narrow (e.g., participation in collision sports). We maintained a fixed family-wise error rate using an ordered testing approach that exploits the hierarchical relationships between our exposure definitions. Compared to teenagers who did not participate in any after-school activities, those who participated in sports had statistically significantly better self-rated and mental health outcomes in early adulthood.

Wear and use of prostheses in sport by adolescents with upper limb absence: A preliminary mixed-methods study

Background: There is minimal research on sports participation in adolescents with upper limb absence (ULA) and specifically on the impact of prosthesis provision. Objectives: This study explored using activity monitoring sensors and interviews to gain insight into levels of sport participation and associated prosthesis use in active adolescents with ULA. Study design: A mixed methods study using a convergent parallel design. Methods: Semi-structured interviews and activity diaries were used to investigate sports and related activities undertaken during a 2-week period. Prosthesis wear/use were determined via accelerometers worn on the anatomical and prosthetic wrists throughout; interview data added context. For comparison, accelerometer data and activity diaries were captured from similar aged anatomically intact (AI) participants. Results: Three adolescents with unilateral transradial ULA and 4 AI adolescents were recruited. Two ULA participants wore prostheses during sport (16.2% and 56.5% of the time). The third rarely wore their prosthesis. The ability to participate in sport has a powerful influence on participants' lives, and prostheses were used when participants felt they offered specific benefits. In contrast to AI participants, who showed similar reliance on each of their arms throughout, when wearing a prosthesis, users were heavily reliant on the anatomical arm, including during periods playing sports. Conclusions: Prosthesis use facilitated access to some sports, although they were only used by 2 out of 3 participants for short periods. The methods were acceptable to adolescent individuals with ULA.

Exploring the Link Between Physical Activity, Sports Participation, and Loneliness in Adolescents Before and Into the COVID-19 Pandemic: The HUNT Study, Norway.

The COVID-19 pandemic's effects on adolescents' physical activity, sports involvement, and feelings of loneliness remain inadequately understood. This study aimed to explore the shifts in leisure-time physical activity, sports participation, and loneliness among adolescents before and during the pandemic, positing that the pandemic has led to decreased physical activity and sports engagement, as well as heightened loneliness, where more active adolescents experience lower loneliness levels. This study included a prior four-year follow-up cohort from the same region two decades earlier to explore the existence of typical longitudinal aging effects in a cohort not affected by the pandemic. Prospective and longitudinal data from two cohorts of the Young-HUNT Study two decades apart involving adolescents aged 13-19 years were utilized. The controls were as follows: Cohort 1 from the Young-HUNT1 (YH1) Survey included 2399 adolescents with follow-up in the Young-HUNT2 (YH2) Survey four years later. Cohort 2 included the Young-HUNT4 (YH4) Survey (2017-2019) of 8066 adolescents, with a subset of 1565 participants followed up in the Young-HUNT COVID Survey (YHC) (2021) after exposure to the COVID-19 pandemic and associated restrictions. Changes over time were assessed using McNemar's tests and dependent sample T-tests, while multinomial logistic regression modeled within-individual changes in loneliness, adjusting for age, gender, and other factors. The findings revealed a significant decline in physical activity and sports participation in both cohorts from early to late adolescence. Additionally, there was a considerable increase in reported loneliness, more after exposure to the pandemic and especially among girls, but without any difference in historical initial levels (between cohorts). Inactive adolescents faced a greater risk of increased loneliness, while those participating in sports had a lower risk of loneliness. Physically inactive boys had a higher risk of loneliness compared with physically active boys at both time points in Cohort 2, which was higher than in the control Cohort 1. There was no historical difference between initial assessments. Adolescents experienced a significant decrease in physical activity and sports participation, along with increased loneliness, from early to late adolescence. Given the protective benefits of physical activity against loneliness and the negative longitudinal trends observed, public health initiatives should focus on increasing physical activity and reducing sports drop-out rates among adolescents to combat rising loneliness.

Sport participation, weight status, and physical fitness in French adolescents.

The primary objective of this study was to investigate the associations between sport participation and weight status with physical fitness among French adolescents. The secondary aim was to establish sex- and age-specific physical fitness percentiles for French adolescents. The sample comprised 8084 adolescents (4126 boys, 3958 girls), aged 10-14years. Participants were tested on cardiorespiratory fitness and muscular strength using the following tests: 20-m shuttle run test and handgrip strength test. A questionnaire on organized sport participation was completed. Physical fitness levels were better in boys (P < 0.005). Handgrip strength increased with age whereas 20-m shuttle run performance decreased with age. Overweight and obese adolescents had significantly lower cardiorespiratory fitness levels than their normal-weight peers (P < 0.005), whereas normal-weight adolescents had lower cardiorespiratory fitness than thin adolescents (P < 0.005). Sport participation was higher for boys (57.2% boys vs. 52.8% girls) (P < 0.001). Adolescents who participated in at least one organized sport (either through a club or at school) were fitter than those who did not participate in organized sports (P < 0.005). Adolescents who engaged in organized sports were more active and physically fit than those who did not participate. The fitness benefits of club sports are greater than those provided by school-based sports, highlighting the potential of sports clubs as a key setting for promoting health. What is Known: • Physical fitness is a strong marker of health in children and adolescents. • The last French Report Card highlighted the lack of fitness data and the need for nationwide programs, while showing a significant decline in cardiorespiratory fitness among youth in recent decades.. What is New: • This study reveals that adolescents participating in organized sports have better physical fitness compared to their peers who do not, emphasizing the potential advantages of club sports over school-based activities. • We highlight the need for targeted strategies, particularly for overweight or obese adolescents and girls, to increase participation in organized sports and enhance health outcomes. • The study emphasizes the need to develop policies that improve access to organized sports clubs and expand physical education in schools, aiming to improve CRF in adolescents.

Anatomical medial patellofemoral ligament reconstruction improves sport participation and activity levels in adolescents with recurrent patellar dislocation.

This study aims to evaluate the clinical outcomes of an anatomical medial patellofemoral ligament (MPFL) reconstruction and the effects of concomitant patellofemoral joint injuries and radiological findings on outcomes in adolescents with recurrent patellar dislocation (RPD). Between January 2011 and January 2020, a total of 34 patients (19 males, 15 females; median age: 15.6 years; range, 13 to 17 years) with RPD who underwent anatomic MPFL reconstruction were retrospectively analyzed. Lateral release was performed as indicated. Clinical outcomes were evaluated preoperatively and at the final follow-up using the Visual Analog Scale (VAS), Lysholm, Kujala, and Tegner activity rating scales. Magnetic resonance imaging was performed to detect concomitant injuries such as bone, cartilage, and soft tissue injuries. The mean follow-up was 5±2 years. All postoperative knee functions and activity levels were statistically significantly improved without re-dislocation (p<0.001). There was no statistically significant relationship between the presence and location of cartilage lesions and clinical outcomes (p>0.05). Patients with cartilage lesions had a significantly higher CatonDeschamps index and a higher incidence of bone edema in both the patella and femur than patients without. Anatomic MPFL reconstruction with meticulous physical therapy has successful clinical outcomes, prevents re-dislocation, and increases participation in sports and activity levels in adolescent patients with RPD. Although cartilage injuries are common after RPD, it has no adverse effect on clinical outcomes in the mid-term.

Who Plays and Who Doesn't? An Intersectional Examination of Disparities in Adolescent Sport and Physical Activity Lesson Participation

PurposeFew reports include more than 1–2 social identities when examining organized sport and physical activity (PA) participation among adolescents. We used a quantitative intersectional approach to examine disparities in adolescent sport and PA lesson participation. MethodsNinth and 11th grade 2022 Minnesota Student Survey participants (N = 62,940) self-reported social identities and team sport and PA lessons. Social identities included sex assigned at birth, gender modality, sexual identity, racial and ethnic identity, access to resources (i.e., economic status), weight status, and mental health/behavioral/emotional problems. We used Exhaustive Chi-square Automatic Interaction Detection to identify prevalence of participation among adolescents with different intersecting social identities. ResultsHalf of the sample played sports and one-quarter participated in PA lessons. Participation varied substantially at the intersections of social identities. Whereas participants in the highest prevalence sports participation groups were predominantly White, heterosexual, and had high resource access, participants in the lowest prevalence groups held multiple marginalized social identities: only 12.8% of adolescents with least access to resources who were questioning their gender identity and sexual identity, or who reported a sexual identity not listed, participated in sports. Regarding PA lessons, youth in the highest prevalence groups were predominantly heterosexual, had highest access to resources, and were youth of color; by comparison, most of the lowest prevalence groups comprised youth who had medium/low resource access and/or high body mass index, and often a diverse sexual, gender, or racial/ethnic identity. DiscussionMultiply marginalized adolescents are under-represented in sports and PA lessons. Organizations should address interlocking barriers to participation.

Shared Decision-Making About Returning to Sport After Recovery From Pediatric Concussion: Clinician Perspectives.

Describe how sports medicine clinicians support decision making about sport participation after concussion recovery with adolescent patients and their parents. Specific areas of inquiry related to how clinicians framed the decision, what factors they considered in how they approached the decision process, and how they navigated discordance within families. Qualitative study. Tertiary care sports medicine clinics at 4 children's hospitals in the United States. Individual interviews were conducted with 17 clinicians practicing in sports medicine settings. N/A. Semi-structured interviews explored clinician approaches to supporting decision making, with the question guide informed by components of the Ottawa Decision Support Framework. Clinicians routinely incorporated aspects of shared decision making (SDM) into their conversations with families. This included ensuring all parties were informed about risk and aligned behind a shared value of adolescent well-being. Mediation strategies were used to manage discordance between adolescents and their parents, and between parents. These strategies aimed to facilitate a decision that was adolescent centered. When clinicians believed that there was a medical benefit to modifying the adolescent's sport participation practices, or when they did not believe the athlete was psychologically ready to return to the sport in which they were injured, they initiated conversations about alternative activities. In such situations, they used persuasive communication practices to encourage families to strongly consider this option. The strengths and strategies used by sports medicine clinicians in this study provide a foundation for guidance or intervention development aimed at supporting SDM after concussion with adolescents and their families.

Beneficial Effects of Exercise on Hypertension-Induced Cardiac Hypertrophy in Adolescents and Young Adults.

Hypertension-induced cardiac hypertrophy is widely known as a major risk factor for increased cardiovascular morbidity and mortality. Although exercise is proven to exert overall beneficial effects on hypertension and hypertension-induced cardiac hypertrophy, there are some concerns among providers about potential adverse effects induced by intense exercise, especially in hypertensive athletes. We will overview the underlying mechanisms of physiological and pathological hypertrophy and delineate the beneficial effects of exercise in young people with hypertension and consequent hypertrophy. Multiple studies have demonstrated that exercise training, both endurance and resistance types, reduces blood pressure and ameliorates hypertrophy in hypertensives, but certain precautions are required for hypertensive athletes when allowing competitive sports: Elevated blood pressure should be controlled before allowing them to participate in high-intensity exercise. Non-vigorous and recreational exercise are always recommended to promote cardiovascular health. Exercise-induced cardiac adaptation is a benign and favorable response that reverses or attenuates pathological cardiovascular remodeling induced by persistent hypertension. Exercise is the most effective nonpharmacological treatment for hypertensive individuals. Distinction between recreational-level exercise and competitive sports should be recognized by medical providers when allowing sports participation for adolescents and young adults.

Use of physical activity as a coping strategy mediates the association between adolescent team sports participation and emerging adult mental health

PurposeWe explored how team sport participation during adolescence may have prepared emerging adults to use physical activity (PA) as a coping strategy during the COVID-19 pandemic and therefore protect their mental health. MethodsMATCH study participants reported their involvement in team sports from age 11 to 18. At age 20, in the context of the COVID-19 pandemic, they reported their level of positive mental health, strategies to cope with stress, and perception of how helpful these are. Mediation analyses were used to estimate the natural direct effect of number of years of team sport participation during adolescence on emerging adults’ mental health, and the natural indirect effect through using PA as a coping strategy. ResultsData from 454 participants were available. PA was the most prevalent coping strategy reported (51.5%) and 74% of those using this strategy reported it helped a lot. More years of team sport participation during adolescence was associated with higher odds of reporting PA as a coping strategy (OR [95% CI] = 1.012 [1.007; 1.017]) and with higher level of mental health during emerging adulthood (β [95% CI] = 0.059 [0.024; 0.095]). The natural indirect effect suggests that the use of PA as a coping strategy partially explained the association between team sport participation in adolescence and mental health in emerging adulthood (NIE [95% CI] = 0.038 [0.002;0.074]). DiscussionMore team sports participation during adolescence is associated with better mental health during emerging adulthood. This association may operate through using PA to cope with stress.

Sports participation in childhood and adolescence and physical activity intensity in adulthood.

The aim of the present study was to analyze the association between sports participation in childhood and adolescence and the practice of physical activity at different intensities in adulthood, and to verify if some sports participation characteristics such as number of sports; type of sport (individual, collective or a combination of both) and total estimated sports participation time are associated with the different physical activity intensities in adulthood. This is a cross-sectional study. This study included 129 young adults of both sexes aged 18-25 years. Sports participation in childhood (7-10 years) and adolescence (11-17 years) was retrospectively estimated through specific questionnaire. Light, moderate, vigorous and moderate to vigorous intensity physical activity was objectively estimated by accelerometers. To verify the association between SP in childhood and adolescence and BP intensities in adults, multiple linear regression was adopted, with 5% significance. Analyses showed that, in females, sports participation in childhood (β = 0.315; R2 = 0.14; P = 0.020) and persistence in sports participation (β = 0.364; R2 = 0.18; P = 0.007) were positive predictors of vigorous physical activity in adulthood. In addition, the comparison according to the specificities of the sport practice, indicated that participation in two or more sports in childhood, one sport and collective sports in adolescence and at least one year of sports participation throughout childhood and adolescence were associated with longer time in vigorous physical activity intensity and MVPA (minutes/day) in adult females (P < 0.05). It could be concluded that sports participation indicators in childhood and adolescence were considered predictors of vigorous physical activity in adult females. In addition, number of sports, type of sport and practice time in childhood and adolescence seem to predict vigorous and moderate to vigorous levels of physical activity for adult females.

Return to play after head injury in adolescent sports: evaluating football versus other sports.

Increased adolescent sports participation has raised concerns about higher rates of concussions, a prevalent injury among young athletes with potential long-term effects. Discrepancies in concussion recovery and management protocols across various sports underscore a critical issue in youth athletics. This study aimed to examine the relationship between sport type and the number of games missed following a concussion to inform targeted management strategies. Data from 7445 postinjury ImPACT tests for athletes aged 12-22 years, collected from 2009 to 2019, were analyzed across different sports: baseball, basketball, cheerleading, football, ice hockey, lacrosse, soccer, softball, swimming, track and field, volleyball, and wrestling. The number of days and normalized missed games (NMG), a metric accounting for the different number of games in a season for different sports, were used to evaluate the effect of concussions across different sports. ANOVA, t-tests, and linear regression analyses were performed to model the effect of sport type on games missed in a season while controlling for sex, age, concussion history, diagnosed learning disability (DLD), and attention-deficit/hyperactivity disorder (ADHD). Multivariable linear regression analysis demonstrated that football participation significantly increased NMG (β 1.681, 95% CI 0.807-2.554; p < 0.001) and days missed (β 1.637, 95% CI 1.044-2.231; p < 0.001) after head injury. Concussion diagnoses were also found to significantly increase NMG (β 2.344, 95% CI 1.629-3.059; p < 0.001) and days missed (β 1.560, 95% CI 1.074-2.045; p < 0.001), as well as history of prior concussion (NMG: β 7.791, 95% CI 7.368-8.215; p < 0.001; days missed: β 5.232, 95% CI 4.945-5.520; p < 0.001). In contrast, factors such as age, sex, DLD, ADHD, and concussions causing loss of consciousness did not significantly affect NMG or days missed. ANOVA with Tukey Honest Significant Difference indicated that compared with football, ice hockey (mean difference [MD] 5.4 days, p = 0.011) and track and field (MD 4.1 days, p = 0.006) were associated with significantly more days being missed after head injury. Conversely, basketball (MD -3.0, p < 0.001) and volleyball (MD -2.6, p = 0.005) were associated with fewer missed games. Adolescents playing football missed fewer days and games after concussion than other contact and noncontact sports, including ice hockey and track and field, raising questions about variations in return-to-play protocols and cultural attitudes within sports. Further research is needed to determine the factors affecting games missed across sport types in adolescent athletics and return-to-play protocols.

Research on the Promotion Mechanism of Sports Participation in Children and Adolescents Based on Social Cognitive Theory

This study aims to explore the promotion mechanism of children and adolescents' sports participation, based on social cognitive theory. By analyzing the theoretical framework of social cognitive theory, this study aims to gain a deeper understanding of the internal mechanisms of children and adolescents' participation in sports, and provide theoretical support for promoting their physical and mental health development. The study adopted various research methods, including literature review, expert interviews, observation, and teaching experiments, to systematically analyze the elements and promotion mechanisms of children and adolescents' participation in sports. The research results show that social cognitive theory plays a crucial role in interpreting children and adolescents' sports participation behavior, cognitive processes, and emotional experiences. In terms of practice, research has proposed multiple strategies, including innovating the teaching mode of physical education for children and adolescents, integrating sports training camps with social cognitive theory, and designing intervention programs for children and adolescents in sports participation based on social cognitive theory. Future research directions include providing diverse role models, encouraging diverse ways of social participation, and establishing a positive sense of social identity to further promote the practice and development of sports participation among children and adolescents.

Association between sports participation and resilience in school-attending students: a cross-sectional study.

This research sought to identify the association between sports participation and resilience in children and adolescents as a means to enhance mental health. A comprehensive survey was carried out, encompassing primary, middle, and high school students from chosen educational institutions. The analytical sample comprised 67,281 students of school age. Sports participation and resilience were evaluated using validated assessment tools, while relevant covariates, such as sex and school grade, were assessed through self-reported questionnaires. Generalized Linear Models were applied to ascertain the association between sports participation and resilience for the entire sample, and separately for subgroups divided by gender or school grade, after controlling for covariates. Among the 67,281 school students, males constituted 51.9% of the sample. Approximately 47.1% of the entire sample reported no sports participation, and the average resilience score was 24.7. The regression model analysis revealed that, in the entire sample, increased in sports participation was linked to higher resilience scores (odds ratio [OR] for 1-3 times per month: 1.20, 95%CI: 1.16-1.24; OR for 1-2 times per week: 1.38, 95%CI: 1.33-1.43; OR for 3 times or more per week: 1.72, 95%CI: 1.65-1.79). Analyses stratified by gender and school grade indicated that sports participation was consistently associated with greater resilience. This study provides cross-sectional evidence supporting the positive association between sports participation and the resilience of children and adolescents, underscoring the potential of encouraging sports participation as a strategy for promoting mental health resilience. The findings presented herein should be subject to further confirmation or refutation in future research endeavors.

Changes in Sports Participation, Specialization, and Burnout From 7th to 12th Grade: Final Results From a 6-Year Longitudinal Study.

Previous studies show alarming rates of burnout and dropout from sports participation and physical activity in the youth population. Early sports specialization may increase the risk of injury, burnout, and eventual dropout from sports. Sports participation will decrease, specialization will increase, and burnout will increase from junior high to high school. Prospective longitudinal study. Level 2b. The graduating class of 2023 was surveyed longitudinally in the fall of each school year from 7th to 12th grade (n = 35-77 from middle to high school based on new enrollment participants and attrition). Survey questions asked about sports participation, specialization, and burnout. Responses were analyzed by grade level using mixed effects linear and logistic regression accounting for repeated measures. The number of days per week in which students engaged in at least 60 minutes of strenuous exercise progressively decreased from 7th through 12th grade from 4.0 to 2.3 days per week (P < 0.01). The percentage of students participating in sports also decreased from 7th to 12th grade from 82% to 39% (P < 0.01). More students stopped participating in a sport (38% vs 22% to 29%, P = 0.04), quit a sport to focus on a single sport (60% vs 46% to 49%, P = 0.01), or reported that 1 sport was most important to them (71% vs 54% to 67%, P = 0.06) in 9th grade. Burnout in sports did not differ significantly by grade level (19% to 23%, P > 0.99). In contrast, burnout in school was significantly more common in high school (54% to 69%) compared with middle school (36%, P < 0.01). Burnout in school was higher in female students compared with male students (68% vs 38%, P < 0.01). Organized sports participation and general physical activity decreased from middle to high school, with the entry into high school at 9th grade being a time at which a significant number of students dropped other sports to specialize in a single sport or stopped participating. Burnout in sports did not appear to increase with age; however, there was an increase in school-related burnout as students transitioned from middle to high school. Our results highlight the need for continued research into sports participation, specialization, and burnout in adolescents. In addition, health professionals and the community (parents, coaches, teachers) supporting youth athletes may consider positive interventions during the periods of transition from middle to high school to include facilitating different tracks of sports participation (including a developmental or recreational model of play) to reduce dropout from sport and supportive measures to lessen burnout from sports and from school.

A Review of the Impact of Sporting Role Model-Led Interventions on Physical Activity and Sport Participation of Female Youth

There is a lack of evidence of on the impact of how sporting role models (SRM) influence adolescent physical activity (PA) and/or sport participation (SP) levels. The main aim of this review was to identify SRM-led interventions and highlight the evidence of impact of SRMs on female adolescents’ participation in PA and/or SP. A systematic review of peer-reviewed literature using key search terms was completed using electronic databases (APA PsycInfo, SPORTDiscus, and PubMed). The inclusion criteria were as follows: (a) Participants were ≤18 years old, (b) results were reported for female participants, (c) the study included an intervention arm/element, (d) an SRM or equivalent terminology was used as part of the intervention, (e) PA levels and/or SP was evaluated, and (f) peer-reviewed articles published in English. A total of 7,169 peer-reviewed articles were identified and screened. A systematic review of grey literature to identify SRM programs was also carried out through Google search engine, direct contact with relevant sporting organizations, and with authors who had written about role models, and 45 programs were identified. Identified documents were screened using the same inclusion criteria as described above. The results identified one peer-reviewed and 15 grey literature programs, all of which were deemed to be of poor quality. The programs revealed a lack of theoretical base and rigor in methodology, no objective PA or SP assessment, poor demographic context of participants and role models, and lack of evaluation.

The Study on Impact of Parental Sports Behavior on Adolescent Students' Sports Participation from the Perspective of Family Environment

The Study on Impact of Parental Sports Behavior on Adolescent Students' Sports Participation from the Perspective of Family Environment

Pre-analysis protocol for an observational study on the effects of adolescent sports participation on health in early adulthood

Abstract: We will study the impact of adolescent sports participation on early-adulthood health using longitudinal data from the National Study of Youth and Religion. We focus on two primary outcomes measured at ages 23–28 — self-rated health and total score on the PHQ9 Patient Depression Questionnaire — and control for several potential confounders related to demographics and family socioeconomic status. Comparing outcomes between sports participants and matched non-sports participants with similar confounders is straightforward. Unfortunately, an analysis based on such a broad exposure cannot probe the possibility that participation in certain types of sports (e.g., collision sports like football or soccer) may have larger effects on health than others. In this study, we introduce a hierarchy of exposure definitions, ranging from broad (participation in any after-school organized activity) to narrow (e.g., participation in limited-contact sports). We will perform separate matched observational studies, one for each definition, to estimate the health effects of several levels of sports participation. In order to conduct these studies while maintaining a fixed family-wise error rate, we deployed an ordered testing approach that exploits the logical relationships between exposure definitions. Our study will also consider several secondary outcomes including body mass index, life satisfaction, and problematic drinking behavior.

Youth Preseason Performance on the Sport Concussion Assessment Tool 5 Across Multiple Sports.

To examine preseason Sport Concussion Assessment Tool 5 (SCAT5) performance of adolescent sport participants by environment (in-person/virtual), sex, age, concussion history, collision/noncollision sport participation, and self-reported medical diagnoses. Cross-sectional. Canadian community and high-school sport settings. Three thousand eight hundred five adolescent (2493 male, 1275 female, and 37 did not disclose; 11- to 19-year-old) sport participants. Sport Concussion Assessment Tool 5 administration method (in-person/virtual), sex (male/female/unreported), age (years), concussion history (0/1/2/3+), collision/noncollision sport participant, and self-reported medical diagnoses [attention deficit disorder or attention-deficit/hyperactivity disorder, headache/migraine, learning disability, and psychiatric disorder (ie, anxiety/depression/other)]. Preseason SCAT5 outcomes including total number of symptoms (TNS; /22), symptom severity score (SSS; /132), Standardized Assessment of Concussion (SAC; /50), and modified Balance Error Scoring System (mBESS; /30). Multiple multilevel linear or Poisson regression complete case analyses adjusting for clustering and robust standard errors, with β-coefficients (95% CI) back-transformed to indicate an increase/decrease in SCAT5 subdomains when relevant for clinical interpretation. Virtual (V) performance was associated with fewer symptoms reported [TNS Difference V-IP = -1.53 (95% CI, -2.22 to -0.85)], lower SSS [-2.49 (95% CI, -4.41 to -0.58)], and fewer mBESS errors (IP) [-0.52 (95% CI, -0.77 to -0.27)] compared with in-person. For every one-year increase in age, more symptoms [TNS = 0.22 (95% CI, 0.01-0.44)], higher SSS [0.52 (95% CI, 0.01-1.06)], higher SAC [0.27 (95% CI, 0.15-0.38), and poorer balance [mBESS = -0.19 (-0.28 to -0.09)] were observed. Differences between males and females were also seen across all SCAT5 outcomes. Individuals reporting any medical diagnosis or 3+ concussion history also reported more symptoms (TNS) and higher SSS than those who did not. Administration environment, sex, age, concussion history, and medical diagnoses were associated with SCAT5 subdomains and are important considerations when interpreting the SCAT5 results.

Evolution of perceptions of motivational climates in youth soccer development and a comparison of opinions between families and players

Motivation is one of the general variables with the greatest influence on behaviour, making it essential to understand the perspectives of various stakeholders as well as the theories that examine it. Furthermore, it stands as one of the primary causes of dropout in adolescent sports participation. The primary objective of this research is to ascertain the assessment of the motivational climate from both players and families in youth football development categories. Specific objectives include validating whether the adaptation of the SMS and AGSYS questionnaires yields congruent results, comparing the perspectives of families and players regarding the motivational climate, and finally, examining the opinions and evolution of the motivational climate among players across different age categories. The sample consisted of 143 individuals from the top-tier teams in youth development stages at the Cuarte Sports Club (Zaragoza, Spain). Descriptive and inferential statistics were employed using the SPSS 22.0 statistical software. The findings indicate that the adaptation of both questionnaires does not measure the same constructs, significant differences exist in the opinions of families and players, and lastly, cadet-level players demonstrate distinct opinions in comparison to other age categories.
