However, there is a limited understanding of the underlying mechanism in this relationship between PE and physical activity (PA). This study aimed to examine how the quality of PE in high school is associated with future physical activity engagement in young adulthood and whether physical literacy is a mediator in this relationship. A group of 280 college students (62.1% women; M_age = 20.09, SD = 2.04) were recruited from 11 universities in the United States. The students filled out an online survey measuring the quality of PE in high school, leisure-time physical activity, and physical literacy. A path analysis revealed a good fit of the mediation model with sex as a covariate (χ²/df = 1.73, <i>p</i> = .02; CFI = 0.99; IFI = 0.99; TLI = 0.98; RMSEA = 0.05, 90% CI [0.02, 0.08]). Quality of PE has a significant direct association (β = 0.12) with physical activity and an indirect association with physical activity through physical literacy (β = 0.05). The findings illustrate that high-quality high school PE is associated with physical activity directly and indirectly through physical literacy. It is critical to provide high-quality high school PE by addressing the environment, curriculum, instruction, and assessment to develop physical literacy and physical activity participation. Improving physical literacy through high-quality PE and other settings (e.g., school sports and community clubs) is a viable way to promote PA participation.</p>","PeriodicalId":94191,"journal":{"name":"Research quarterly for exercise and sport","volume":" ","pages":"1-10"},"PeriodicalIF":0.0,"publicationDate":"2025-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143813225","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Athletic activity for adults with disabilities requires adaptation to their physical and/or intellectual limitations.

Ten qualitative interviews with 5 players from the US and 5 from Scandinavia explored player experiences with adaptive team sports. The authors assessed overall health once using the World Health Organization Quality of Life Survey (WHOQOL-BREF).

WHOQOL-BREF means averaged 60 points for all four domains, no significant differences existed between US and Scandinavian players. Heart rate data demonstrated a significant increase in heart rate during scrimmage compared to rest. <b>Conclusion:</b> Adaptive team sports provided participants with valuable social interaction, decreased isolation, and increased opportunities for mentorship and advocacy.
