本研究的目的是使用二维生物力学模型，在角速度范围为30至210 ° s（-1）的向心等速伸膝过程中检查肌肉和胫股力。5名无膝关节损伤史的男性参与了研究。最大力矩范围为30 deg s（-1）时的226.2 Nm至210 deg s（-1）时的166.4 Nm。最大肌力范围为30 ° s（-1）时的7.5倍体重至210 ° s（-1）时的5.7倍体重。胫股压缩力范围为30 ° s（-1）时的7.5倍体重至210 ° s（-1）时的5.7倍体重，胫股剪切力范围分别为0.9至0.8倍体重，这些结果表明，在最大等速膝关节伸展过程中产生的力相对于其他强大的动态活动显著降低，但高于在最大等速膝关节伸展过程中产生的关节力。简单的步行和骑自行车活动。在关节损伤康复的最后阶段，需要适当的预防措施和等速运动方案的调整。
The purpose of this study was the examination of muscular and tibiofemoral forces during concentric isokinetic knee extension at angular velocities ranging from 30 to 210 deg s(-1) using a two-dimensional biomechanical model. Five males without knee joint injury history participated in the study. The maximum moment ranged from 226.2 Nm at 30 deg s(-1) to 166.4 Nm at 210 deg s(-1). The maximum muscular force ranged from 7.5 times body weight at 30 deg s(-1) to 5.7 at 210 deg s(-1). The compressive tibiofemoral force ranged from 7.5 times body weight at 30 deg s(-1) to 5.7 at 210 deg s(-1) and the shear tibiofemoral force ranged from 0.9 to 0.8 times body weight respectively, These results indicate that the forces developed during maximal isokinetic knee extension are significantly reduced relative to other powerful dynamic activities but are higher than joint forces during simple walking and cycling activities. Appropriate precautions and adjustment of the isokinetic protocol are required in the final phases of joint injury rehabilitation.
