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.
十名训练有素的男性排球运动员进行了单腿和双腿垂直反跳动作。记录了地面反作用力、摄像数据和肌电图数据。单腿跳的跳跃高度是双腿跳的58.5%。单腿跳时髋关节和踝关节的平均净扭矩更高。单腿跳时踝关节的净功率输出极高。这种高功率输出是由于单腿跳时腓肠肌两头的激活水平较高。股内侧肌也发现了较高的激活水平。复杂动作跳跃的单侧和双侧表现之间的这些差异与基于等长和等速实验的文献报道的差异一致。
