本研究的主要目的是評估體操選手與一般非運動員之平衡能力的差異性，實驗對象共分為二組：體操選手組包括10名大專體育院校體操代表隊男選手(22.2±2.6歲)，運動年齡至少5年；非運動員組包括10名一般非體育科系男學生(21.4±0.5歲)。測試前先請受試者隨意踢擊足球二次，以判定受試者的支撐腳。靜態站姿穩定性測試所使用的實驗儀器是碼表，不穩定性靜態平衡能力評估是使用平衡測定器及K.A.T.-2000平衡測量儀。主要計算人體左右擺動次數和靜態平衡指數；不穩定性動態平衡能力評估是利用K.A.T.-2000平衡測量儀來測試動態平衡指數。研究結果顯示：一、靜態站姿穩定性測試結果，體操選手組與非運動員組幾乎相同。二、不穩定性靜態平衡能力評估結果，體操選手組顯著優於非運動員組(p<.05)。三、體操選手組的不穩定性動態平衡能力顯著優於非運動員組(p<.05)。由研究結果得知：經過較有規律之訓練的體操選手，其本體感覺接受器、內耳前庭系統及視覺神經系統亦經較頻繁的刺激，因此，專項運動所需的平衡能力優於一般料系非運動員。

This study investigated the balance ability of elite gymnasts and non-athletes. The subjects consisted of two groups. The gymnasts group consisted of ten elite gymnasts with mean age 22,2±2.6 years and the second group consisted of ten non-athletes with a mean age of 21.4±0.5 years. The subjects were asked to kick a ball with a single leg twice before the commencement of the test. The leg selected to kick the ball was defined as the dominant leg, while the other leg was referred to as the supporting leg. The results of this study were summarized as followed: (1) the static standing steadiness of the gymnasts group was better than that of the non-athletes group, (2) the unstable static balance ability of gymnasts group was significantly better than that of the non-athletes group, (3) the unstable dynamic balance ability of gymnasts was significantly better than that of the non-athletes group. Based on the findings of this study, it is suggested that regular sport training could significantly enhance balance ability.
