研究问题
Participation in organized sport among senior Masters athletes (aged ≥ 50 years) has increased substantially in recent decades (–).；These athletes represent a rapidly growing population that maintains high levels of training and competition into later life.
方法
The study was approved by the Institutional Review Board (IRB #2022-368), and all participants provided written informed consent prior to participation.；A total of 203 participants (100 female) provided complete demographic and hamstring strength data across both years.；Analyses were restricted to participants with complete demographic and hamstring strength data.；Participants completed a brief questionnaire capturing demographic information and physical activity using the International Physical Activity Questionnaire–Short Form (IPAQ-SF).
核心结论
Males demonstrated greater absolute peak force, with a very large effect size (Cohen's d = 1.54, 95% CI 1.22 to 1.85; mean difference = 85.6 N, 95% CI 70.2 to 100.9; p < 0.001).；Males also demonstrated greater relative peak force, with a moderate effect size (Cohen's d = 0.76, 95% CI 0.47 to 1.04; mean difference = 0.53 N/kg, 95% CI 0.34 to 0.73; p < 0.001).；Age was associated with lower absolute peak force (−2.10 N per year, 95% CI −3.09 to −1.11, p < 0.001). ‖ 结论：These findings provide practical reference values for interpreting eccentric hamstring strength assessments in older athletic populations and may assist clinicians and practitioners involved in athlete monitoring and performance evaluation.
局限
Future work should extend NHE assessment across the adult lifespan and into less physically active populations to better characterize how ageing, training status, and sport participation influence eccentric hamstring strength across later life.；Interpretation of the present findings should nevertheless remain cautious because the analysis was cross-sectional rather than longitudinal, and the observed association between age and strength may not reflect within-person decline over time.；Collectively, these findings support recommendations that asymmetry values should be interpreted within population-specific contexts rather than relying on universal cut-points derived primarily from younger at
