[Purpose] This study assessed the relationships between peak toe flexor muscle strength, ankle dorsiflexion range of motion, and countermovement jump height. [Subjects and Methods] Eighteen healthy volunteers participated in the study. Each participant completed tests for peak toe flexor muscle strength, ankle dorsiflexion range of motion, and countermovement jump height. [Results] The results showed (1) a moderate correlation between ankle dorsiflexion range of motion and countermovement jump height and (2) a high correlation between peak first toe flexor muscle strength and countermovement jump height. Peak first toe flexor muscle strength and ankle dorsiflexion range of motion are the main contributors to countermovement jump performance. [Conclusion] These findings indicate that the measurement of peak first toe flexor muscle strength and ankle dorsiflexion range of motion may be useful in clinical practice for improving jump performance in athletes training for sports such as volleyball and basketball.
[目的] 本研究评估了趾屈肌峰值肌力、踝关节背屈活动范围和反向运动跳跃高度之间的关系。[对象与方法] 18名健康志愿者参与了本研究。每位参与者完成了趾屈肌峰值肌力、踝关节背屈活动范围和反向运动跳跃高度的测试。[结果] 结果显示：(1) 踝关节背屈活动范围与反向运动跳跃高度之间存在中度相关性；(2) 拇趾屈肌峰值肌力与反向运动跳跃高度之间存在高度相关性。拇趾屈肌峰值肌力和踝关节背屈活动范围是反向运动跳跃表现的主要影响因素。[结论] 这些发现表明，测量拇趾屈肌峰值肌力和踝关节背屈活动范围可能在临床实践中有助于提高排球和篮球等运动项目运动员的跳跃表现。
