ABSTRACT

We examined the relationships between heights of different vertical jumps and isometric single-joint strength characteristics of ankle, knee, hip, and trunk joints in young male soccer players (n = 117). The highest peak torque and rate of torque development (RTD) outcomes were in low to moderate correlation with jump heights (r = 0.25–0.50). The correlations were generally higher for bilateral than unilateral jumps. Linear regression models accounted for 33–35% and 24.5 of the variance in bilateral and unilateral jump height, respectively. Hip extension peak torque, ankle RTD and trunk lateral flexion peak torque were most consistently included in the regression models. Our results suggest the that single-joint isometric testing does not seem to be useful to detect weaknesses related to vertical jump performance. The relative importance of individual lower limb joints for vertical jumping seems comparable. Trunk strength should not be neglected as the determinant of jumping performance.

摘要

我们研究了年轻男性足球运动员不同垂直跳跃的高度与踝、膝、髋和躯干关节等长单关节力量特征之间的关系（n = 117）。最高峰扭矩和扭矩发展率（RTD）结果与跳跃高度（r= 0.25–0.50)。双侧跳跃的相关性通常高于单侧跳跃。线性回归模型分别占双边和单边跳跃高度方差的 33-35% 和 24.5。髋关节伸展峰值扭矩、踝关节 RTD 和躯干侧屈峰值扭矩最一致地包含在回归模型中。我们的结果表明，单关节等长测试似乎对检测与垂直跳跃表现相关的弱点没有用处。单个下肢关节对垂直跳跃的相对重要性似乎相当。作为跳跃表现的决定因素，不应忽视躯干力量。
