SportsMetrics训练对ACL损伤风险相关生物力学和功能表现的影响：系统综述和Meta分析
简介
这项系统综述与meta分析纳入9项研究、310名以女性为主的运动员，评估SportsMetrics训练（SMT）对ACL损伤相关生物力学缺陷和功能表现的影响。SMT与动态膝外翻（SMD -1.09，p<0.0001）和LESS（SMD -1.08，p<0.0001）的变化相关，敏捷、动态平衡、爆发力和速度亦有改善，核心力量变化不显著（SMD 0.57，p=0…
英文摘要
BACKGROUND: This meta-analysis aimed to evaluate the effects of SportsMetrics training (SMT) on ACL injury-related biomechanical deficits and functional performance outcomes in athletes. METHODS: Literature searches were conducted in four databases from inception to May 10, 2026. The RoB 2 and ROBINS-I tools were used to assess the risk of bias, while meta-analyses and sensitivity analyses were performed using CMA 4 software. The GRADE approach was applied to evaluate the quality of evidence. Primary outcomes were dynamic knee valgus (DKV) and the Landing Error Scoring System (LESS). Secondary outcomes included core strength, agility, dynamic balance, speed, and power. RESULTS: Nine studies (310 athletes, predominantly female) were included. SMT was associated with changes in surrogate biomechanical outcomes, including DKV (SMD: -1.09, p < 0.0001) and LESS (SMD: -1.08, p < 0.0001), as well as functional performance outcomes: agility, dynamic balance, power, and speed. Core strength (SMD: 0.57, p = 0.154) showed non-significant changes. CONCLUSIONS: SMT was associated with improvements in several biomechanical and functional outcomes. Higher-quality RCTs and prospective injury registration outcomes are required to confirm these findings. However, the relationship between improvements in these surrogate outcomes and actual ACL injury reduction remains unestablished. TRIAL REGISTRATION: This study was a priori registered at PROSPERO (CRD420261389110).
