The purpose of this study was to determine which variables of the range of motion (ROM) and strength of the hip, and ankle are associated with squat depth. In total, 101 healthy subjects (64 males, 37 females) participated in the study. Outcome measures consisted of the ROM of hip flexion, hip internal rotation, external rotation, ankle dorsiflexion with an extended and flexed knee joint, and strength of the hip flexor and ankle dorsiflexor. Squat depth was measured using SIMI motion analysis software. Pearson correlation was used to determine the relationship between variables and squat depth. Multiple stepwise regression analysis was performed to determine variables associated with squat depth. The multiple regression model indicated that ankle dorsiflexion with a flexed knee and the hip flexion ROM were significantly associated with squat depth in male subjects (R(2) = 0.435) and ankle dorsiflexion with an extended knee and dorsiflexor strength were significantly associated with squat depth in female subjects (R(2) = 0.324). Thus, exercises to increase the ROM of the ankle dorsiflexion, hip flexion, and dorsiflexor strength can be recommended to improve squat performance. Future studies should assess an increased ROM of the ankle dorsiflexion, hip flexion, or dorsiflexor strength effect on deep squat performance.
本研究的目的是确定髋关节和踝关节的活动范围（ROM）及力量的哪些变量与深蹲深度相关。共有101名健康受试者（64名男性，37名女性）参与了该研究。结果测量包括髋关节屈曲、内旋、外旋的ROM，膝关节伸展和屈曲时的踝关节背屈，以及髋屈肌和踝关节背屈肌的力量。使用SIMI运动分析软件测量深蹲深度。采用Pearson相关性分析来确定变量与深蹲深度之间的关系。进行多元逐步回归分析以确定与深蹲深度相关的变量。多元回归模型表明，膝关节屈曲时的踝关节背屈和髋关节屈曲ROM与男性受试者的深蹲深度显著相关（R(2)=0.435），膝关节伸展时的踝关节背屈和背屈肌力量与女性受试者的深蹲深度显著相关（R(2)=0.324）。因此，可推荐进行增加踝关节背屈ROM、髋关节屈曲和背屈肌力量的练习，以改善深蹲表现。未来的研究应评估增加踝关节背屈ROM、髋关节屈曲或背屈肌力量对深度深蹲表现的影响。
