RESUMEN

Introduction: Lack of physical activity (PA) among children living in rural communities is a documented public health problem. Although studies have examined community conditions defined by a rural-urban dichotomy, few have investigated rural community conditions with a concentration of Hispanic/Latino people. This cross-sectional study examined sociodemographic characteristics associated with youth sport (YS) participation and daily PA among children living within concentrated Hispanic/Latino rural U.S. Midwest communities. Methods: During spring 2022, 97% of 3rd-6th grade children (n = 281, aged approximately 8-12 years) attending school in rural Midwestern communities (n = 2) with >50% concentration of Hispanic students participated in the Wellscapes Project, a community randomized trial. Participants completed the Youth Activity Profile and supplemental National Survey of Children's Health questions assessing PA behaviors and YS participation. Caregivers of a subsample of children (n = 215; males, n = 93; females, n = 122) consented to pair their child's survey results with school enrollment records (e.g., free/reduced lunch status and race and ethnicity). Mixed models with community as a random effect examined main and interaction effects of grade, sex, ethnoracial status, and family income on YS participation and these sociodemographic characteristics and YS participation on daily moderate-to-vigorous PA (MVPA). Results: Approximately half of children participated in YS. Non-Hispanic White children (n = 82) were over five times more likely to participate in YS than Hispanic peers (n = 133) (OR = 5.54, 95% CI = 2.64-11.61, p < 0.001). YS participants accumulated 8.3 ± 2.3 more minutes of daily MVPA than non-participants (p < 0.001). Sixth graders, females, and Hispanic children reported lower daily MVPA than comparison groups (p < 0.05). Significant interaction effects on daily MVPA between grade and ethnoracial status (F(3, 204) = 3.04, p = 0.030) were also found. Discussion: Disparities in sport participation and PA outcomes based on sociodemographic characteristics exist among children living in ethnoracially diverse rural communities. Strategies to promote YS participation, including community structural changes, may help reduce PA disparities. The research provides valuable insights for policymakers, public health professionals, and community members to address YS participation barriers, not limited to cost, while considering other PA-promotion efforts to improve child population health.

RESUMEN

ABSTRACT: Children's participation in sport is a critical component to their physical and social development and as such, efforts should be made to provide all children with the opportunity to play. In recent years, there has been an observed shift in the focus of youth sports from that of participation for the health benefits of physical activity and fun to that of winning and competing. As a result, there has been a rise in club sports offerings and a subsequent reduction in recreational sports opportunities. This change presents unique challenges to children's access to sport and may not adequately support their overall physical, social, and emotional development. This commentary will discuss the benefits and barriers to increasing recreational sport opportunities using the Social Ecological Model as a framework. It also will propose solutions that can be implemented at the intrapersonal, interpersonal, organizational, community, and public policy levels to revive recreational sports.

RESUMEN

INTRODUCTION: Healthy People 2030, a U.S. government health initiative, has indicated that increasing youth sports participation to 63.3% is a priority in the U.S. This study quantified the health and economic value of achieving this target. METHODS: An agent-based model developed in 2023 represents each person aged 6-17 years in the U.S. On each simulated day, agents can participate in sports that affect their metabolic and mental health in the model. Each agent can develop different physical and mental health outcomes, associated with direct and indirect costs. RESULTS: Increasing the proportion of youth participating in sports from the most recent participation levels (50.7%) to the Healthy People 2030 target (63.3%) could reduce overweight/obesity prevalence by 3.37% (95% CI=3.35%, 3.39%), resulting in 1.71 million fewer cases of overweight/obesity (95% CI=1.64, 1.77 million). This could avert 352,000 (95% CI=336,200, 367,500) cases of weight-related diseases and gain 1.86 million (95% CI=1.86, 1.87 million) quality-adjusted life years, saving $22.55 billion (95% CI=$22.46, $22.63 billion) in direct medical costs and $25.43 billion (95% CI= $25.25, $25.61 billion) in productivity losses. This would also reduce depression/anxiety symptoms, saving $3.61 billion (95% CI=$3.58, $3.63 billion) in direct medical costs and $28.38 billion (95% CI=$28.20, $28.56 billion) in productivity losses. CONCLUSIONS: This study shows that achieving the Healthy People 2030 objective could save third-party payers, businesses, and society billions of dollars for each cohort of persons aged 6-17 years, savings that would continue to repeat with each new cohort. This suggests that even if a substantial amount is invested toward this objective, such investments could pay for themselves.

RESUMEN

BACKGROUND: There are little to no data on whether any associations exist between sport specialization and mental health in youth softball athletes. HYPOTHESIS: Highly specialized youth softball athletes will have worse self-reported depression and anxiety symptom scores compared with low and moderate specialized athletes. STUDY DESIGN: Cross-sectional survey. LEVEL OF EVIDENCE: Level 4. METHODS: An online cross-sectional survey was distributed in the fall of 2021 to a national sample of female youth softball athletes between the ages of 12 and 18 years. Sport specialization status was determined using a 3-point specialization scale that classifies either low, moderate, or high. The patient health questionnaire-9 (PHQ-9) and the 7-item general anxiety disorder scale (GAD-7) were used to assess self-reported symptoms of depression and anxiety. Comparison also included sports participation and specialization behaviors between specialization groups. RESULTS: A total of 1283 subjects (mean age, 15.1 ± 1.7 years) fully completed the survey. After adjusting for covariates, lower scores were reported on both the PHQ-9 and GAD-7 by highly specialized athletes compared with moderate or low specialization athletes (PHQ-9, high = 8.6 ± 0.4; moderate = 11.2 ± 0.3; low = 10.9 ± 0.5; P < 0.01; GAD-7, high = 6.5 ± 0.4; moderate = 8.6 ± 0.3; low = 8.4 ± 0.4, P < 0.01). Conversely, higher scores were reported on both scales for athletes who received private softball coaching compared with those who did not (PHQ-9, 11.5 ± 0.3 vs 9.0 ± 0.3; P < 0.01; GAD-7, 8.8 ± 0.3 vs 6.9 ± 0.3, P < 0.01). Finally, athletes who reported an arm overuse injury in the previous year reported higher PHQ-9 scores (10.8 ± 0.3 vs 9.8 ± 0.3; P < 0.01). CONCLUSION: While sport specialization, as measured by the validated 3-point scale, was not associated with increased anxiety and depression symptom scores, other aspects of specialization behavior such as private coaching or overuse injury history were associated with worse scores on these scales, indicating potential concern for anxiety and depression. However, although the differences we observed were statistically significant, they did not exceed the minimal clinically important difference values that have been established for the PHQ-9 (5 points) or GAD-7 (4 points). CLINICAL RELEVANCE: This project is a first step toward understanding the sport specialization behaviors and their influence on the mental health of youth softball athletes. Focusing on investigating specialization behaviors further may reveal to be a better indicator of risk of developing anxiety and depression symptoms compared with utilizing the 3-point specialization scale.

RESUMEN

This study investigated whether dietary supplement acceptance mediated the relationship between supplement use and doping attitudes in youth sports. To this end, we employed a two-wave half-longitudinal design during a sports season (time point one [T1] to time point two [T2]). The sample consisted of 217 elite youth athletes (47% male; mean age = 16.98 years, standard deviation = 0.88) who competed in team sports (43%; N = 93; basketball, floorball, handball, and ice hockey) and individual sports (57%; N = 124; alpine skiing, biathlon, cross-country skiing, swimming, and tennis). The participants were recruited from eight Norwegian sports academy high schools that provide extracurricular, higher-level training and specialization for youth athletes. Results from structural equation modeling analysis indicated that dietary supplement acceptance (T2) mediated the positive relationship between supplement use (T1) and doping attitudes (T2) when accounting for prior levels of the mediator and the outcome variable. These findings suggest that when young athletes used dietary supplements at the start of the season to improve their performance, they were more likely to view the use of supplements as acceptable and to report more favorable attitudes toward doping at the end of the season six months later. For those seeking to prevent doping in youth sports, targeting athletes' views on the acceptable use of dietary supplements may be important.

RESUMEN

CONTEXT: Participation in sports during youth is typically beneficial for mental health. However, it is unclear whether elite sport contexts contribute to greater risk of psychological distress or disorder. The aims of this paper are to highlight conceptual issues that require resolution in future research and practice, and to examine the key factors that may contribute to the mental health of elite youth athletes (EYAs). EVIDENCE ACQUISITION: A narrative overview of the literature combined with the clinical and research expertise of the authors. STUDY DESIGN: Narrative overview. LEVEL OF EVIDENCE: Level 5. RESULTS: EYAs experience a range of biopsychosocial developmental changes that interact with mental health in a multitude of ways. In addition, there are various sport-specific factors that contribute to the mental health of EYAs that may become more prominent in elite contexts. These include - but are not limited to - patterns relating to athlete coping and self-relating styles, the nature of peer, parental, and coach relationships, organizational culture and performance pressures, and mental health service provision and accessibility. CONCLUSION: A range of critical factors across individual, interpersonal, organizational, and societal domains have been shown to contribute to mental health among EYAs. However, this evidence is limited by heterogeneous samples and varied or imprecise terminology regarding what constitutes "youth" and "elite" in sport. Nevertheless, it is clear that EYAs face a range of risks that warrant careful consideration to progress to best practice principles and recommendations for mental health promotion and intervention in elite youth sport. SORT: Level C.

RESUMEN

OBJECTIVE: To systematically map the coach education (CE) component of injury prevention programmes (IPPs) for youth field sports by identifying and synthesising the design, content and facilitation strategies used to address competency drivers and behaviour change. DESIGN: Scoping review. DATA SOURCES: PubMed, PsycInfo, EMBASE, CINAHL, SportDiscus and Google Scholar electronic databases were searched using keywords related to IPPs and youth field sports. ELIGIBILITY CRITERIA FOR SELECTING STUDIES: Studies of IPPs in youth field sports, that provided 'train-the-trainer' education to coaches as designated delivery agents. RESULTS: 20 studies from two field sports (soccer/football; n=17, Rugby Union; n=3) fulfilled the eligibility criteria. Eleven CE interventions occurred in the preseason and 18 occurred at one time-point (single day). Five studies cited use of a behavioural change theory or model in the design of their CE, most frequently the Health Action Process Approach model (n=5); and use of behavioural change techniques varied. Twelve of twenty studies (60%) reported some form of ongoing support to coaches following the CE primary intervention concurrent with IPP implementation. CONCLUSION: CE that occurs on 1 day (one time-point) is most popular for preparing coaches as delivery agents of IPPs in youth field sports. While recognising pragmatic barriers, more expansive in-service training, support and feedback may enhance the effective implementation of IPPs.

RESUMEN

Neuromuscular training warm-up programs can reduce injury rates in youth sports, but they often have poor uptake and adherence. Delivering such programs in school physical education classes may provide greater public health benefit, particularly if they promote improved injury knowledge and prevention beliefs amongst students. The purpose of this secondary analysis of a large cluster-randomized controlled trial was to understand how students' (age 11-15 years) knowledge and beliefs change after exposure to an evidence-informed neuromuscular training warm-up program. Six schools delivered the program for a 12-week period in the initial study year (n=566) and two continued to use it in a subsequent "maintenance" year (n=255). Students completed a knowledge and beliefs questionnaire at baseline, 6-week, and 12-week timepoints. Knowledge scores ranged from 7/10 to 8/10 at all timepoints and students generally believed that injuries are preventable. On average, there was less than a one-point change in knowledge between timepoints and there was no change in the median belief scores. There were no meaningful differences between sexes, grades, or previous injury. These findings highlight that knowledge and beliefs are unlikely to change passively through program exposure. More active strategies are needed to improve injury prevention perceptions in this population.

RESUMEN

From a holistic perspective, the talent development environment (TDE) influences not only the athletic development but also the development of personal skills as well as the wellbeing of elite youth athletes. Alongside research on the effects of broader environmental features on athlete-related talent development (TD) outcomes, the importance of the closer social climate (i.e., teammates, coaches, support staff) is also emphasized. Therefore, the purpose of this study was to examine the relationship between environmental features, the social climate and athlete-related TD outcomes (I). Additionally, an exploratory analysis was conducted to investigate the role of motivational climate and psychological safety in the relationship between environmental features and athlete-related TD outcomes (II). To this end, 345 German elite youth athletes completed an online survey assessing their perceptions of environmental features, coach-created motivational climate, and psychological safety as well as wellbeing, performance satisfaction, and life skills development. The results revealed that environmental features (especially long-term development focus, effective coach-athlete communication, and the social network), motivational climate and psychological safety were all significantly associated with the outcome variables. These findings underline the significance of environmental features for athlete-related TD outcomes of young talented athletes in German elite youth sports. However, the results indicated that motivational climate and psychological safety did not have significant indirect effects on the relationship between TDE features and athlete-related TD outcomes. Thus, it remains to be questioned if and what other processes influence this relationship.

RESUMEN

Purpose: Despite the known health and wellbeing benefits of taking part in sport for children and adolescents, it is reported that sports participation declines during adolescence. The purpose of this study was to explore current organized youth sport participation rates across Europe for both males and females and update current understanding. Method: Sport participation registration data was collected for 18 sports from 27 countries. In total, participation data was collected from over 5 million young people from Under 8s (U8s) to Under 18s (U18s). Differences in the participation rates between age categories were investigated using a generalized linear mixed effects model. Results: Overall, males were four times more likely to participate in organised youth sport than females' participants, with this trend apparent across all age categories and across most sports. There was a significant decrease across sports in participation rates for males during adolescence from U14-U16 and U16-U18. There was a significant decrease in participation rates for females from U14-U16 for most sports except but an increase in participation rates from U16-U18 for 12 out of 18 sports. Soccer (1262%), wrestling (391%) and boxing (209%) were the sports that had greater male sport participation rates. In contrast, dance sports (86%) and volleyball (63%) had more female participants than males. This research shows male sports participation is significantly greater than female in youth sport across Europe. Conclusion: Furthermore, findings showed that for both male and female participants, participation rates increased from U8-U14 for the majority of sports followed by reduced participation rates during adolescence. Findings of this research can be used by national governing bodies and sporting organizations to inform youth sport participation initiatives.

RESUMEN

BACKGROUND: Sport-related concussion (SRC) has been shown to induce cerebral neurophysiological deficits, quantifiable with electroencephalography (EEG). As the adolescent brain is undergoing rapid neurodevelopment, it is fundamental to understand both the short- and long-term ramifications SRC may have on neuronal functioning. The current systematic review sought to amalgamate the literature regarding both acute/subacute (≤28 days) and chronic (>28 days) effects of SRC in adolescents via EEG and the diagnostic accuracy of this tool. METHODS: The review was registered within the Prospero database (CRD42021275256). Search strategies were created and input into the PubMed database, where three authors completed all screening. Risk of bias assessments were completed using the Scottish Intercollegiate Guideline Network and Methodological Index for Non-Randomized Studies. RESULTS: A total of 128 articles were identified; however, only seven satisfied all inclusion criteria. The studies ranged from 2012 to 2021 and included sample sizes of 21 to 81 participants, albeit only ∼14% of the included athletes were females. The studies displayed low-to-high levels of bias due to the small sample sizes and preliminary nature of most investigations. Although heterogeneous methods, tasks, and analytical techniques were used, 86% of the studies found differences compared with control athletes, in both the symptomatic and asymptomatic phases of SRC. One study used raw EEG data as a diagnostic indicator demonstrating promise; however, more research and standardization are a necessity. CONCLUSIONS: Collectively, the findings highlight the utility of EEG in assessing adolescent SRC; however, future studies should consider important covariates including biological sex, maturation status, and development.

RESUMEN

Recently, the Tactical Assessment Instrument in Football (TAIS) was developed to address football's tactical requirements in terms of game phases, learners' roles, and organizational levels of play. In this study, we sought to evaluate the psychometric properties of this existing instrument in the Physical Education (PE) context and for youth sport teams (ages 8-12 years). Our research design involved: (a) participants playing 37 football games, (b) assessing participants via observation with the TAIS and (c) conducting psychometric analysis on the obtained assessment data. For the psychometric analysis, we carried out our work in four phases: (a) a statistical analysis of the evaluation criteria, (b) analysis of the instrument's structural dimensions, (c) internal item reliability analysis, and (d) provision of evidence for external validity. Participants were 592 children (156 girls, 436 boys; ages 8-12 years) from 74 PE classes or sport teams (from three institutional contexts - schools, community-based sports, and sports clubs) in Spain. We selected 12 tactical criteria and grouped them into four theoretical dimensions (appropriate attack, inappropriate attack, appropriate defense, inappropriate defense) to confirm the instrument's structural dimensions. The Cronbach alpha and Omega McDonald coefficients were greater than .70. The TAIS discriminated between participants from the three institutional contexts, offering evidence of the instrument's external validity. Thus, the TAIS now has sufficient psychometric support for assessing learning of football tactics in PE and youth sport teams. This instrument facilitates an ecological assessment of youth players' understanding of football tactics through four theoretical tactical dimensions and 12 criteria involving information about four learners' roles (both attack and defense, on- and off-the-ball) and three organizational tactical levels of play (whole team, small groups of learners, and individual learners).

RESUMEN

OBJECTIVES: Parents of youth sport athletes report a variety of stressors associated with their child's participation in youth sport settings. However, research examining associations between parents' stressors and relevant outcomes is limited due to the lack of a comprehensive and validated measure of parents' stressors in youth sport. Therefore, the purpose of this research was to develop and provide preliminary validation of the Stressors among Parents in Youth Sport Survey (SPYSS). METHOD: In Study 1 we developed an initial version of the survey and tested the factor structure of the scale using exploratory and confirmatory factor analyses with a sample of 1187 Canadian parents of minor hockey athletes. In Study 2, we administered the SPYSS to an independent sample of 783 parents with children participating in multiple sports, who also completed measures of parent stress and well-being, as well as parent-athlete outcomes, to establish convergent and divergent validity evidence and test associations with relevant outcomes for youth sport parents. RESULTS: The results from Study 1 supported the development of a 42-item survey of parental stressors in youth sport. Results from Study 2 provided further evidence for the factor structure and validity evidence of a measure assessing parental stressors in youth sport. CONCLUSIONS: The SPYSS assesses the frequency and intensity of a variety of stressors relevant for parents of youth sport athletes. The measure may be a useful tool for researchers, sport organizations, and practitioners to assess, monitor, and target the stressors experienced by parents in youth sport settings.

RESUMEN

Interpersonal coach-and parent development programmes (CDP and PDP, respectively), have the goal to foster positive youth sport experiences through high-quality relations between coaches, parents, and youth athletes. In this paper we systematically reviewed the extant literature and estimate the overall magnitude of such programmes and how they can inform future interventions. Specifically, we aimed to: (a) conduct a systematic review on the literature of interpersonal CDPs and PDPs within the youth sport context; (b) examine the effects of such interventions on youth athlete outcomes via a meta-analysis. English written peer-reviewed publications and grey literature was identified through electronic search in databases and manual searches of reference lists. By utilising a priori criteria for inclusion and exclusion, 33 studies describing interpersonal CDPs, and PDPs were identified in the systematic review. Studies that presented required data for estimation of Hedge's g effect sizes were included in the meta-analysis (k = 27). By and large, the included studies used a quasi-experimental design (58%), sampled from team sports (79%), and reported several delivery methods (e.g., workshops, audio feedback, observations, peer group discussions) and outcome measures (e.g., anxiety, autonomous motivation, self-confidence). Some interventions were based on the same delivery protocols (e.g., Coach Effectiveness Training, Mastery Approach to Coaching) or theoretical frameworks (e.g., Achievement Goal Theory, Self-Determination Theory). The meta-analysis showed statistically significant small, and medium, effect sizes on a subsample of youth athlete outcomes (e.g., task-related climate, fun and enjoyment, anxiety), indicating that coach interpersonal skills can contribute to positive youth sport experiences. Theory-based interpersonal CDPs and PDPs are recommended to expand the knowledge in this field of research.

RESUMEN

The objective of this study is to detect any performance factors in athletics throws between 1997 and 2015 in 662 throwers (15.67 ± 1.01 years of the National Program for Sports Technification of the Royal Spanish Athletics Federation using Machine Learning methods by means of algorithms (Logistic Regression, Random Forest and XG Boost). When examining the importance of the variables with reference to performance, the triple jump (0.20) stands out over the rest of the variables: backward overhead shot throw (0.14), arm span (0.11), vertical jump (0.10), body mass (0.20), height (0.07) and flexibility (0.03). In each discipline the triple jump takes the lead in shot put (0.20), discus (0.21) and hammer (0.29) throws, while backward overhead shot throw does in javelin, the variables rearranging themselves in a particular way depending on the discipline. These findings enable the early detection of potential talents as well as their subsequent sport specialization (AU)


El estudio aborda la detección de factores de rendimiento en los lanzamientos atléticos utilizando técnicas de Machine Learning, en 662 lanzadores (15,67 ± 1,01 años) del Programa Nacional de Tecnificación Deportiva de la Real Federación Española de Atletismo entre 1997 y 2015, mediante diferentes algoritmos (Logistic Regression, Random Forest y XGBoost). Al medir la importancia de las variables en función del rendimiento, el triple salto (0,20) destaca sobre el resto de variables: lanzamiento dorsal (0,14), envergadura (0,11), salto vertical (0,10), masa corporal, estatura (0,07) y flexibilidad (0,03). En cada disciplina, el triple salto encabeza la importancia en los lanzamientos de peso (0,20), disco (0,21) y martillo (0,29), mientras que el lanzamiento dorsal lo hace en la jabalina (0,20). Las variables se reordenande forma particular modificando su importancia para cada disciplina. Estos hallazgos permiten mejorar la detección inicial de posibles talentos, así como su posterior especialización deportiva (AU)

RESUMEN

Background: The degree of deterioration in sarcopenia parameters may be affected by a person's level of physical activity (PA) and sedentary behavior (SB). Our study focused on examining the PA and SB of active older adults including those with and without history of sports in youth. Methods: Forty-four participants (20 men and 24 women, mean age of total sample 76.1 ± 5.2 years) were included in analysis of PA, SB habits and sarcopenia parameters, determined by skeletal muscle index, hand-grip strength, gait speed, Timed Up and Go tests (TUG). PA and SB were recorded with accelerometers. Our primary aim was to compare participants with (AH) or without a sport history in youth (NAH), in their sarcopenia parameters and PA and SB habits. Results: When divided participants in two groups (AH and NAH) and adjusting for age, we have detected the differences for skeletal muscle index (p = 0.007) and hand-grip strength (p = 0.004) in favor of participants who were engaged in sports in youth. We did not find any differences in PA and SB habits between the AH and NAH groups. After adjusting for age, participants with a higher number of daily steps, longer moderate to vigorous physical activity (MVPA) bouts, a higher number of MVPA bouts in a day and higher overall MVPA engagement achieved better results in hand-grip strength and TUG. Participants with lower SB had better TUG and gait speed results. Conclusions: Our findings suggest that engaging in sports activities in youth can make a difference with sarcopenia parameters. Although we found no differences in PA and SB habits between participants with AH and NAH, participants with an athlete history performed better results in sarcopenia parameters.

RESUMEN

Perfectionistic pressure from coaches and parents is likely to contribute to the development of perfectionism in youth athletes. However, if and how perfectionistic pressure from coaches and parents interact to predict the development of perfectionism is unknown. With this in mind, the present study tested a new model - the 2 × 2 Model of Perfectionistic Pressure - that focuses on the different combinations of perfectionistic pressure youth athletes can experience. Four within-person combinations of perfectionistic pressure are identified and compared: Pure coach pressure (high coach pressure/low parental pressure), pure parental pressure (low coach pressure/high parental pressure), mixed pressure (high coach pressure/high parental pressure), and low pressure (low coach pressure/low parental pressure). To test the model, a sample of 210 youth athletes (M age = 14.68 years) completed measures of perfectionistic strivings, perfectionistic concerns, coach pressure to be perfect, and parental pressure to be perfect. Moderated hierarchical regression and simple slopes analyses revealed that mixed pressure was related to the highest levels of both perfectionistic strivings and perfectionistic concerns. The findings provide initial evidence for the new model and suggests it will be useful in studying the development of perfectionism and other outcomes in sport.

RESUMEN

Using short-term longitudinal data, the primary goal of the present study was to examine the interplay between adolescents' sports-related intrapersonal (e.g., sports values) and interpersonal factors (e.g., perceived parental involvement) in relation to sports dropout. A secondary goal was to explore the direction of effects in the association between intra- and interpersonal factors. A total of 420 adolescents (39% girls, Mage = 14.06; SDage = 0.33) responded to a set of survey questions over two consecutive years. Results from structural equation modeling suggested that parental involvement predicted adolescents' dropout one year later, via sports values. Further, the results suggested that the direction of influence is mainly from parents to adolescents. Overall, the findings indicate that adolescents whose parents attend their practices and games perceive sports activities as fun, important and useful; as a result, adolescents are less likely to dropout. The findings offer an improved understanding of how parents' behaviors may influence adolescents' dropout of organized sports.

RESUMEN

Some sports coaches not only invest considerable time and energy in their athletes, but also attach their self-worth to the successes and failures of their athletes. Grounded in Self-Determination Theory, the present study aimed to examine the theoretical predictors and outcomes of such Athlete-Invested Contingent Self-worth (AICS). Results from a cross-sectional study (Study 1; N = 740, Mage = 34.37 years) and an experimental vignette-based study among youth sports coaches (Study 2; N = 318, Mage = 38.94 years) indicated that AICS was positively related to a controlling coaching style and negatively related to a structuring style. Study 1 showed that a perceived evaluative club board was positively related to AICS, and Study 2 further demonstrated that poor performance was negatively associated with AICS and that an evaluative climate was related to AICS through experiences of need frustration. The discussion focuses on the pitfalls of coaches' contingent self-worth for the development of their athletes.
