Participants were equally randomized to either an experimental group (n = 20) performing supervised DS exercises five times weekly or a control group (n = 20) maintaining regular training. Comprehensive assessments conducted at baseline, 4, 8, and 12 weeks demonstrated that the intervention group achieved statistically significant improvements in: hip range of motion (ROM) (dominant leg: 3.01 effect size [ES], p ≤ 0.001; non-dominant leg: 3.06 ES, p ≤ 0.001), pain reduction (ES = 0.85, p ≤ 0.001), dynamic balance (dominant leg: 0.30 ES, p ≤ 0.001), and countermovement jump performance (ES = 0.31, p ≤ 0.001). No significant enhancements were observed in 20-meter sprint times or agility test performance (p > 0.05). The subsequent 4-week detraining period resulted in partial but significant loss of gains across multiple outcomes including hip ROM (dominant: 0.80 ES; non-dominant: 0.64 ES, both p ≤ 0.001) and pain relief (ES = 0.40, p ≤ 0.001), indicating that sustained clinical benefits require ongoing implementation of the stretching protocol. These findings support the utility of DS for managing LBP in football athletes while highlighting the importance of program continuity.","PeriodicalId":17066,"journal":{"name":"Journal of Sports Sciences","volume":" ","pages":"1572-1586"},"PeriodicalIF":2.3,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144225808","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Authentic leadership, an emerging leadership style characterised by self-awareness, transparency, moral behaviour, and balanced processing, may hold potential value in mitigating athlete burnout. However, longitudinal research exploring the reciprocal relationship between authentic leadership and athlete burnout at the individual level remains scarce, particularly regarding the underlying mechanisms, such as psychological capital and empathy . Empirical studies on these pathways are still insufficient. In this study, researchers adopted a longitudinal design and constructed a Random Intercept Cross-Lagged Panel Model (RI-CLPM) and a Linear Mixed Model (LMM) to examine the relationship between authentic leadership and athlete burnout from both intra-individual and interpersonal perspectives. From March 2024 to November 2024, a total of 441 athletes (Mage = 20.28, SD = 2.08) completed three waves of assessments. The results indicated that: (a) authentic leadership and athlete burnout were bidirectionally related; (b) authentic leadership indirectly predicted athlete burnout through psychological capital; and (c) empathy moderated the relationship between psychological capital and athlete burnout. These findings provide longitudinal empirical evidence for the reciprocal influence between authentic leadership and athlete burnout and offer new theoretical insights into the psychological regulation processes of individuals in competitive sports. .","PeriodicalId":17066,"journal":{"name":"Journal of Sports Sciences","volume":" ","pages":"1685-1701"},"PeriodicalIF":2.3,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144285077","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Throughout the lifespan, relative power had its peak at 14 years, declined until age 20 and then declined further but slower until the maximum age of 64 years. Absolute power remained fairly stable until age 45 after which it slowly declined until maximum age.

Our methodology consisted of two Delphi survey rounds and an expert panel meeting using modified Nominal Group Technique.

The COS included the Squat Jump Test (paired with accelerometery-based instrumentation) and the Timed Up-and-Go Test for the function and function and activities domain, respectively. No test was identified for the participation domain, however, experts proposed using daily-life accelerometery until more suitable outcome measures are defined and validated.
