Voluntary sway is the periodic movement of one's body back and forth. The study aimed to clarify the effects of sway frequency on center of pressure and joint angle during voluntary sway. We measured 10 unrestricted voluntary sway conditions with different frequencies and natural pace conditions. The frequencies ranged from 0.1 to 1 Hz in 0.1-Hz increments. The joint angles and centers of pressure during voluntary sway were compared between the conditions. The joint angle amplitude of the trunk and knee were greater in the slow frequency condition than in the fast frequency condition. The trunk and knee joint angles during voluntary sway were considered to change according to the sway frequency.
自愿摆动是指人的身体前后周期性的运动。本研究旨在阐明在自愿摆动过程中摆动频率对压力中心和关节角度的影响。我们测量了 10 种不同频率和自然步速条件下的无约束自愿摆动情况。频率以 0.1Hz 为增量在 0.1 到 1Hz 之间变化。对不同条件下自愿摆动时的关节角度和压力中心进行了比较。在慢频率条件下，躯干和膝关节的关节角度幅度大于快频率条件。在自愿摆动过程中，躯干和膝关节的角度被认为是根据摆动频率而变化的。
