Dynamic knee valgus (DKV), commonly observed during functional movements, is recognized as a key biomechanical factor contributing to the risk of anterior cruciate ligament (ACL) injury. Given its importance in injury prevention, this study aimed to investigate the effects of a warm-up program on jump-landing pattern and lumbopelvic function in female basketball players exhibiting dynamic knee valgus. The present study employed a quasi-experimental design. Thirty female basketball players with DKV were screened using the single-leg landing (SLL) test and subsequently randomized into control (n = 15) and experimental (n = 15) groups. The jump-landing test was utilized to assess the jump-landing pattern, whereas the forward step-down (FSD) test was implemented to evaluate lumbopelvic function. The experimental group participated in the STOP-X warm-up program over 8 weeks, whereas the control group continued with their traditional warm-up routine. Data were analyzed using a 2 × 2 repeated measures ANOVA, followed by Bonferroni post hoc tests, with statistical significance set at P < 0.05. All analyses were conducted using SPSS version 26. The results revealed significant differences in maximum flexion (F = 20.73; P = 0.001; effect size (ES) = 0.42, percentage change (PC) = ↑4.48%), initial valgus (F = 90.12; P = 0.001; ES = 0.76, PC = ↓32.56%), maximum valgus (F = 151.6; P = 0.001; ES = 0.84, PC = ↓52.86%), and FSD (F = 22.82; P = 0.001; ES = 0.44, PC = ↓51.45%) in the experimental group compared to the control group after following the STOP-X warm-up program. However, no significant impact was observed for the initial flexion (P = 0.49, ES = 0.01) variable. Implementing the warm-up injury prevention program significantly improves jump-landing pattern and optimizes lumbopelvic function. Therefore, it is recommended that coaches incorporate this program in place of traditional basketball warm-up routines. Such an approach may enhance athletic performance while reducing the risk of knee injuries associated with improper landing techniques.Trial registration No: IRCT20231230060574N1, (date of registration on 04/01/2024) registered in the Iranian Registry of Clinical Trials.
动态膝外翻（DKV）在功能性运动中较为常见，被认为是导致前交叉韧带（ACL）损伤风险的关键生物力学因素。鉴于其在预防损伤方面的重要性，本研究旨在调查一项热身计划对表现出动态膝外翻的女性篮球运动员的跳落模式和腰骨盆功能的影响。本研究采用了准实验设计。通过单腿落地（SLL）测试筛选出30名患有DKV的女性篮球运动员，随后随机分为对照组（n = 15）和实验组（n = 15）。跳落测试用于评估跳落模式，而向前下台阶（FSD）测试则用于评估腰骨盆功能。实验组在8周内参与了STOP-X热身计划，而对照组继续其传统的热身常规。数据使用2×2重复测量方差分析进行分析，随后进行Bonferroni事后检验，统计学显著性设定为P < 0.05。所有分析均使用SPSS 26版本进行。结果显示，在遵循STOP-X热身计划后，实验组与对照组相比，在最大屈曲（F = 20.73；P = 0.001；效应大小（ES）= 0.42，百分比变化（PC）=↑4.48%）、初始外翻（F = 90.12；P = 0.001；ES = 0.76，PC =↓32.56%）、最大外翻（F = 151.6；P = 0.001；ES = 0.84，PC =↓52.86%）和FSD（F = 22.82；P = 0.001；ES = 0.44，PC =↓51.45%）方面存在显著差异。然而，对于初始屈曲（P = 0.49，ES = 0.01）变量未观察到显著影响。实施热身预防损伤计划可显著改善跳落模式并优化腰骨盆功能。因此，建议教练采用该计划取代传统篮球热身常规。这种方法可能会提高运动表现，同时降低与不正确落地技术相关的膝盖受伤风险。试验注册号：IRCT20231230060574N1，（于2024年1月4日注册），在伊朗临床试验注册中心注册。
