The intervention programs were conducted twice a week over 6 weeks.Results: Significant improvements in 5-, 10-, and 20-m sprints, as well as the Yo-Yo test, from pretest to posttest in the RSA-15 group (8.17%, 5.92%, 5.02%, and 16.59%) and the RSA-30 group (9.21%, 7.44%, 5.64%, and 18.79%) were observed. Players in the RSA-30 group demonstrated a significant enhancement in maneuverability from pretest to posttest (4.42%). Both the RSA-15 and RSA-30 protocols resulted in enhancements in RSA, particularly in terms of total time (4.71% and 2.30%, respectively), average time (4.71% and 2.30%, respectively), and fastest time (2.97% and 2.32%, respectively). However, only the RSA-15 protocol significantly enhanced the RSA percentage of decrement (24.06%).Conclusion: The present results provide further evidence that, if the primary focus is to maximize RSA performance, RSA-15 should be preferred.

The purpose of this investigation was to characterize the existing sources of surveillance for organized youth sport participation in the United States and highlight knowledge gaps.Methods: We identified nationally representative and free publicly available surveillance data from 2012 to 2022 and report the prevalence of sport participation, the number of sports in which youth participated, and in which specific sports youth participated overall, and by demographic characteristics.Results: Eight surveillance systems met our inclusion criteria. Across systems, estimates ranged from 39.6% to 81.5% of youth participating in any organized sport, with 21.8% to 30.4% of youth participating in one sport. The most common sports were basketball and soccer. Limited information with respect to characteristics of sport participation was collected across systems.Conclusions: Multiple data sources regarding overall organized youth sport participation are available; there is little information further characterizing this participation (eg, setting, volume, specialization), limiting ability to examine important aspects related to public health. Comprehensive, on-going, national surveillance of multiple youth sport domains is needed in the United States to inform sport-promoting policy and ensure equitable provision of quality sport experiences.","PeriodicalId":49712,"journal":{"name":"Pediatric Exercise Science","volume":null,"pages":null},"PeriodicalIF":1.4,"publicationDate":"2024-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142577132","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The intervention involved 20-minute exercise videos, 5 times weekly for 12 weeks, using the UNICEF Kid Power website at home. Feasibility metrics included recruitment (target: 70%), retention (target: 80%), adherence rates, and satisfaction assessed through surveys and interviews. Retention rate-1 was percentage completing posttest surveys, and retention rate-2 was percentage completing posttest accelerometry. Parent logs assessed adherence.Results: Recruitment, retention-1, and retention-2 rates were 73.6%, 93.9%, and 80.5%, respectively. The intervention group had 5 dropouts; wait-list control had none. Sixty-nine percent showed high intervention adherence. Parents consistently expressed satisfaction, finding the intervention enjoyable and beneficial.

Significant differences were identified between the approaching- and circa-PHV groups in 40-m (P = .033, g = 0.89), 50-m (P = .024, g = 1.64), and 60-m (P < .001, g = 0.89) sprint times.
