The authors examined the relationship between the maximum recoverable lean angle via the tether-release method with early- or late-phase rate of torque development (RTD) and maximum torque of lower-limb muscle groups in 56 young healthy adults. Maximal isometric torque and RTD at the hip, knee, and ankle were recorded. The RTD at 50-ms intervals up to 250 ms from force onset was calculated. The results of a stepwise multiple regression analysis, early RTD for hip flexion, and knee flexion were chosen as predictive variables for the maximum recoverable lean angle. The present study suggests that some of the early RTD in the lower limb muscles, but not the maximum isometric torque, can predict the maximum recoverable lean angle.

向前坠落恢复平衡与扭矩降低的下肢率之间的关系。

作者研究了通过系绳释放法获得的最大可恢复倾斜角与早期或晚期扭矩形成率（RTD）以及56名年轻健康成年人下肢肌肉组最大扭矩之间的关系。记录臀部，膝盖和脚踝的最大等距扭矩和RTD。从力开始到最大250毫秒，以50毫秒间隔计算RTD。逐步多元回归分析的结果，髋关节屈曲的早期RTD和膝关节屈曲被选作最大可恢复倾斜角的预测变量。本研究表明，下肢肌肉中的某些早期RTD可以预测最大可恢复倾斜角，但不能预测最大等距扭矩。
