10名训练有素的男子排球运动员分别进行单腿和双腿垂直反向跳跃动作。记录地面反作用力、电影数据和肌电图数据。单腿跳的跳跃高度是双腿跳的58.5%。单腿跳跃时髋关节和踝关节的平均净扭矩较高。在单腿跳跃中，踝关节的净功率输出非常高。这种高功率输出是由两个头部的较高激活水平解释的。单腿跳跃中的腓肠肌在M中也发现了更高水平的激活。股内侧肌这些差异之间的单边和双边性能的复杂运动跳跃被证明是在协议的基础上等距和等速实验的文献报道的差异。
Ten well-trained male volleyball players performed one-legged and two-legged vertical countermovement jumps. Ground reaction forces, cinematographic data, and electromyographic data were recorded. Jumping height in one-legged jumps was 58.5% of that reached in two-legged jumps. Mean net torques in hip and ankle joints were higher in one-legged jumps. Net power output in the ankle joint was extremely high in one-legged jumps. This high power output was explained by a higher level of activation in both heads of m. gastrocnemius in the one-legged jump. A higher level of activation was also found in m. vastus medialis. These differences between unilateral and bilateral performance of the complex movement jumping were shown to be in agreement with differences reported in literature based on isometric and isokinetic experiments.
