Predicting Dropout From Organized Football: A Prospective 4-Year Study Among Adolescent and Young Adult Football Players

Previous studies have shown that enjoyment is one of the key predictors of dropout from organized sport, including organized football. However, prospective studies, particularly studies focused on long-term dropout, are largely lacking. Drawing on the basic principles of interdependence theory, in the present prospective study among 1,762 adolescent and young adult football players (27.1% women, mean age 17.74 years, SD = 1.35), we tested the predictive value of sport enjoyment, perceived alternatives, and restraining forces on football players' short-term (6 months) and long-term (4 years) dropout from organized football. As anticipated, the results of the logistic regression and follow-up analyses indicate that players' enjoyment was the main predictor of (short-term and long-term) dropout. In addition, relative to remainers, dropouts perceived more alternatives in terms of other sports, had fewer family members involved in their football club, and were older at the time they started playing organized football. We conclude that particularly measures aimed at enhancing sport enjoyment may prevent players from dropping out from organized football in both the short and long term. In addition, dropout rates may be reduced by attracting and engaging youth at a very young age (from 6 years), and their siblings, parents, and other family members as well.

Does Public Investment Contribute to Increasing Institutional and Interpersonal Trust?: Place-Based Policies for Sports and Cultural Activities in Cali, Colombia

This paper studies the effect of two place-based policies implemented in Cali, Colombia on social capital and trust. We use the CaliBRANDO survey to account for institutional and interpersonal trust, matching neighborhood of residence and where policies are applied. We set up a difference-in-difference model to estimate the impact of the policies on the indexes that measure trust. We nd that the organized sport policy improves institutional trust by about 4%. Our results are significant for soccer and basketball and not significant for futsal and other activities. The evidence does not support an effect of nightlights on trust.

Sociodemographic Correlates of Organized Sports Participation in a Sample of Middle School Students in China

Background: Organized sport participation (OSP) is considered as one method with the potential to increase overall physical activity (PA) levels in young people. It is essential to understand the correlates of OSP to inform future PA interventions.Purpose: This study aimed to explore the sociodemographic correlates of OSP among middle school students from the Nanjing City of China.Methods: A total of 7,097 adolescents (50.1% girls) aged 12–15 years from Nanjing, China, were recruited in this survey. Self-reported data on sex, grade, race, residence areas, proficient sport skills, and parental highest education were obtained. OSP was assessed by the question asked in the questionnaire on whether participants were involved in any “sports club or team” with the binary answer options of “yes” and “no,” for statistical analysis purposes. Generalized linear models were used to determine the correlates of OSP.Results: Only 16.6% reported participating in any organized sport over the past whole year, while boys (OR = 1.34, 95% CI: 1.18–1.53) and 7th graders (OR = 1.40, 95% CI: 1.18–1.65) were more likely to participate in organized sport. Adolescents being Han ethnicity were less likely to either participate in organized sport (OR = 0.60, 95% CI: 0.40–0.92), or masterless (one or two) proficient sport skills [OR (one) = 0.27, 95%CI: 0.20–0.37; OR (two) = 0.43, 95% CI: 0.36–0.50]. Besides, both residence area and parental highest education were not significantly associated with OSP among the participating adolescents.Conclusion: The current study confirmed that only one-sixth of adolescents participate in the organized sport over the past year. At-risk population subgroups include girls, older adolescents, being Han ethnicity, and those proficient in fewer sport skills. Sex, grades, race, and proficient sport skills were significant correlates of OSP. School, community, and families need to provide more resources and support for disadvantaged populations in OSP.

Age of Early Specialization, Competitive Volume, Injury, and Sleep Habits in Youth Sport: A Preliminary Study of US Youth Basketball

Background: Concerns for youth sports in the United States often focus on early sport specialization, overemphasis on competition, injuries, and burnout. Little research has addressed relationships among the preceding and other concerns, including time away from organized sport, sleep, and perceptions of physical and psychological well-being. Hypothesis: There is an association between reported competitive gameplay volume and specialization, injury, and fatigue among elite youth basketball players. Study Design: Cross-sectional study; convenience sample. Level of Evidence: Level 4. Methods: An anonymous questionnaire was administered to a convenience sample of youth basketball players between 13 and 18 years of age from across the United States. Participants were queried about multiple factors, including the extent of their participation in organized basketball and other sports, time away from organized basketball, injury, sleep, and feelings of exhaustion related to basketball participation. Results: A total of 772 participants (145 girls, 627 boys) completed a survey. All participants played for a select or elite club basketball team and/or a high school basketball team. Overall, 49% played more than 50 games within the past year. A total of 73% were specialized in basketball, 58% prior to age 14 years, and 35% prior to age 11 years. In all, 70% reported less than 1 month away from organized basketball within the past year, and 28% reported no time away. A total of 54% reported sleeping less than the recommended 8 hours each night during the school year. Within the prior year, 55% reported feeling physically exhausted and 45% reported feeling mentally exhausted from basketball. Regression analysis did not find any significant relationships between early specialization prior to age 14 years and basketball-related injury or feelings of mental or physical exhaustion. Conclusion: In this select group of youth basketball players, the majority specialized in basketball prior to age 14 years and reported a large number of competitive events with little time away from organized basketball. Clinical Relevance: The results from a sample of highly competitive youth basketball players indicate issues that warrant further attention and research regarding the potential impact of specialization, frequent competitions, lack of time away from organized sport, and perceptions of well-being in young athletes.

12 A qualitative study of factors that helped prepare athletes for Special Olympics sport programs

Primary Subject area Developmental Paediatrics Background Special Olympics (SO) is working to introduce more child and youth programs provincially and improve currently available programs. To date, there is little research published surrounding the experiences of SO athletes. Given the aim of SO to improve and grow the experience and health of youth, the present study explores the experiences of SO athletes and caregivers to understand what prepares athletes for SO programs and competition. Objectives 1. To describe the experience of SO athletes and caregivers and understand what best prepared them for their involvement in organized sport and physical activity. 2. To offer evidence-based strategies for creating an inclusive and encouraging environment for sports and physical activity for healthy active living and/or preparation for SO involvement. Design/Methods Both athletes and caregivers participated in semi-structured, conversation-based interviews. Eight English-speaking athletes involved in a variety of sports from around the province were interviewed, and four of these interviews included caregivers. Interviews were transcribed and coded using thematic analysis. Results Five themes were identified throughout these interviews. The importance of a supportive environment emerged as a strong theme. Athletes valued the support of caregivers, coaches, and other players and felt this helped them improve and garner more enjoyment from their sport. Many athletes and caregivers discussed what motivated them to get involved and stay involved in SO. Common motivators included: a healthy, active lifestyle, friendships, and social skills. Barriers to involvement also were commonly discussed and included parental support, transportation, dissemination of information, and health concerns. Additionally, many athletes and caregivers felt that early involvement, starting with the basics, was important for developing skills to help transition to sports and competition. Finally, types of programming, including non-specialized vs. specialized activities, were discussed. Advantages of non-specialized activities included more time for practice and integration into society. Conclusion It is important that programs create a supportive environment, as this helps athletes improve and leads to further enjoyment. There is benefit to participation in non-specialized activities. Future programs could consider the addition of inclusive activities, or promotion of these activities. The motivators for involvement should be encouraged, including friendships/social skills and a healthy/active lifestyle. The barriers identified should be addressed when developing programming. Early involvement and learning basic motor skills play an important role in preparing athletes for sports, and competition and may lead to further involvement in sports. Early participation should be encouraged, and programs should find ways to reach more of this population, possibly through schools or physicians.

The Viability of Cross-Country Running Appearing in the Winter Olympic Games

Today, cross-country running celebrates over 200 years of being a practiced, organized sport. Originally adapted as a form of imitation fox hunting by schoolboys in England, it is now a globally sanctioned program governed by World Athletics, which oversees marathon running, track and field, and other athletics events. First introduced to the International Olympic Committee by Percy Fischer, a member of the Olympic track committee of the Amateur Athletics Association in October 1910, cross-country running appeared three times on the program for the Summer Olympic Games in 1912, 1920, and 1924 as both a team and individually-scored event. Due to the overwhelming popularity of track and field and marathon events in the current Olympic Games program in the summer, recent attention has turned to promoting cross-country running––largely practiced in the autumnal and winter months the world over––for inclusion on the Winter Olympic Games schedule. Despite a history of nearly 100 years of efforts for reinclusion back into the Olympics, cross-country running has had difficulty in gaining traction for support for the winter program, largely due to the winter olympic charter mandating all sports be practiced exclusively on snow or ice.
