本研究的目的是使用陳氏被動反覆衝擊式肌力增強器（以下簡稱陳氏增強器）爲訓練工具，讓跆拳道選手接受每秒l次反覆的負重半蹲肌力訓練，探討其訓練效果，期望藉此研究來探討陳氏增強器的訓練效果，以提供教練訓練時參考及儀器改良的依據。在經過四週訓練後，以統計分析得到以下結果：（一）負重半蹲舉最大肌力有顯著進步(p<.05)。（二）30公尺跑、垂直跳高、立定跳遠、折返跑、30秒旋踢等下肢動力有顯著進步(p<.05)。（三）立定三次跳遠沒有顯著進步。（四）實驗組與對照組在動力方面（30秒旋踢）之進步值達顯著(p<.05)，其餘組間並未有顯著差異。

The purpose of this study was to explore the effects of Chen’s passive repeated plyomeric power machine in TKD training. First, the subjects accepted 60RPM squat leg press training, moreover, for the deeper study result of this, hopefully to gain some effects from Chen’s passive repeated plyomeric power machine, and also provide the coaches some references or use for up date the machine later. After four weeks training program, the results of this study were noted as followed: l.Squat let press was improved significant (p<.05). 2.The power of 30m-rui, drop jump, stand jump, triple stand jump, shuttle run, and 30 sec.-front kick were improved significant (p<.05) in lower Extremity. 3.Triple stand jump were not improve too much. 4.The power (30 sec front kick) of experiment group was more improved significant (p<.05) than comparison group, but there was no difference in strength.
