Lorenzetti，S，Gulay，T，Stoop，M，List，R，Gerber，H，谢伦贝格，F和Stussi，E.限制性和非限制性下蹲时膝关节和髋关节的角度和相应力矩的比较。J Strength Cond Res 26（10）：2829-2836，2012-本研究的目的是比较蹲起时膝关节和髋关节的角度和相应力矩。20名受试者进行了限制性和不受限制的蹲起，杠铃负荷分别为0，1/4和1/2体重。实验装置包括一个动作捕捉系统和2个测力板。使用逆动力学计算力矩。在不受限制的下蹲中，膝关节的最大力矩显著高于限制下蹲中的最大力矩，而髋关节的最大力矩显著低于限制下蹲中的最大力矩。在最低位置，限制性技术的最大膝关节屈曲角度约为86度，非限制性技术的最大膝关节屈曲角度约为106度，而最大髋关节屈曲角度在95度和100度之间。在限制下蹲时，髋部的力矩更大，这表明下背部的负荷更大。旨在加强股四头肌的运动员应该考虑不受限制的下蹲，因为膝盖负荷较大，背部负荷较小。
Lorenzetti, S, Gulay, T, Stoop, M, List, R, Gerber, H, Schellenberg, F, and Stussi, E. Comparison of the angles and corresponding moments in the knee and hip during restricted and unrestricted squats. J Strength Cond Res 26( 10): 2829-2836, 2012-The aim of this study was to compare the angles and corresponding moments in the knee and hip during squats. Twenty subjects performed restricted and unrestricted squats with barbell loads that were 0, 1/4, and 1/2 their body weight. The experimental setup consisted of a motion capture system and 2 force plates. The moments were calculated using inverse dynamics. During the unrestricted squats, the maximum moments in the knee were significantly higher, and those in the hip were significantly lower than during restricted squats. At the lowest position, the maximum knee flexion angles were approximately 86 degrees for the restricted and approximately 106 degrees for the unrestricted techniques, whereas the maximum hip flexion angle was between 95 degrees and 100 degrees. The higher moments in the hip during restricted squats suggest a higher load of the lower back. Athletes who aim to strengthen their quadriceps should consider unrestricted squats because of the larger knee load and smaller back load.
