摘要

人體下肢著地碰撞長久以來均是熱門的研究方向，而著地或離地工作在跳躍型態中亦是必備的動作技術，對於著地工作的碰撞傷害與運動表現，經常與勁度作連結。而人體下肢隨著外在環境的影響將不斷的改變適應能力，進而有流暢的運動表現，其主要因素屏除關節的支持作用與肌肉工作效益外，關鍵為勁度的動態調控，說明勁度概念已逐漸受到重視。因此，本研究針對彈簧質量模型與勁度相關研究課題，以運動生物力學的觀點，闡述勁度概念與相關研究發展的應用。提供往後運動科學人員在實務應用與理論整合有更深層的思維。

The lower extremity landing impact is a popular research direction, and jumping pattern of landing or takeoff is a necessary motion technology. The collision injuries and sport performance of lower extremity is often linked with stiffness. Human limb in external environment will continue to change the ability to adapt, and then there is a perfect athletic performance. Besides the role of joint and muscle work, stiffness modulation is a key factor. Description of the stiffness concept has taken seriously. Therefore, this study was to investigate the spring-mass model and stiffness research topics, in view of biomechanics, to explain the concept of stiffness characteristics associated with research and development of applications, in order to provide better ideas to sports science application in analysis and theory of integration.
