Anterior cruciate ligament (ACL) rupture is one of the most common injuries in playing rugby. The aim of this study was to assess the effect of a custom-designed training program on changes in dynamic knee valgus angle (DKV) and Reactive Strength Index (RSI), which are the main risk factors, in a group of female Rugby-7 players. A total of 16 professional Rugby-7 players completed an 8-week KAT program intervention, which was incorporated twice a week throughout this time. In both the pre- and post-tests, dynamic knee valgus was assessed during the drop jump (DJ) test using the frontal plane projection angle (FPPA) method. The jumps were analyzed using Dartfish 2024 software. The post-tests revealed an increase in RSI values ( 0.0496; SD = 1.25 ± 0.44 vs. 1.40 ± 0.35) and a reduction in valgus of the left knee joint ( 0.01; SD = 9.08 ± 11.86 vs.0.00 ± 7.42). The correlation between RSI and the valgus angle produced inconclusive results (rs = -0.69; < 0.01; rs = -0.35; 0.25; rs = -0.38; 0.2; rs = -0.2; 0.51). Cohen's d = -0.37964. The training program proved effective in improving RSI scores and reducing the valgus angle of the left lower limb, which functioned as the supporting leg. These findings potential KAT implementation as a warm-up routine in professional women's rugby clubs.
前交叉韧带（ACL）断裂是橄榄球运动中最常见的损伤之一。本研究的目的是评估一项定制训练计划对一组女子七人制橄榄球运动员动态膝外翻角度（DKV）和反应力量指数（RSI）变化的影响，这两个指标是主要风险因素。共有16名职业七人制橄榄球运动员完成了为期8周的KAT计划干预，在此期间每周进行两次干预。在测试前和测试后，均使用额面投影角（FPPA）方法在纵跳（DJ）测试中评估动态膝外翻情况。使用Dartfish 2024软件对跳跃动作进行分析。测试后结果显示，RSI值有所增加（0.0496；标准差=1.25±0.44对1.40±0.35），左膝关节外翻角度减小（0.01；标准差=9.08±11.86对0.00±7.42）。RSI与外翻角度之间的相关性结果不明确（rs=-0.69；<0.01；rs=-0.35；0.25；rs=-0.38；0.2；rs=-0.2；0.51）。科恩d值=-0.37964。该训练计划被证明可有效提高RSI得分并减小作为支撑腿的左下肢外翻角度。这些发现表明KAT计划有望在职业女子橄榄球俱乐部中作为热身训练实施。
