12週小型抗力球運動對高齡者跌倒風險的影響：以足底壓力為指標

The Effect of 12-Weeks Small Fit Ball Exercise for Falling Risk of Elderly: Foot Pressure as Indicators

本研究主要探討介入12週小型抗力球運動，進行平衡與肌力訓練對於高齡者行走時足底壓力分佈是否有改善。招募36位65歲以上的高齡者，分為實驗組（18位）與控制組（18位）。實驗組參加為期12週的小型抗力球運動；控制組則維持以往的日常活動。所有高齡者在本研究介入前、後皆進行行走時足底壓力分佈測量。以獨立樣本t檢定和單因子共變數分析比較兩組高齡者行走時足底壓力分佈的差異。結果發現實驗組的雙腳在大腳趾足底壓力（T1）、前足足底壓力（M1+M2+M3）及外側中足足底壓力（MF）比控制組達顯著改善。由此可知，本研究的運動介入，改善了高齡者行走時足底壓力分佈，讓高齡者在身體的控制上更加穩定，適合作為預防跌倒的運動介入。

The aim of this study was to investigate whether 12-weeks small fit ball exercise processing balance and muscle strength training improved foot pressure of elderly. 36 elderly people above 65 years old were divided into the exercise group (n=18) and the control group (n=18). The exercise group participated the 12-weeks small fit ball exercise program, and the control group maintained ordinary lifestyle. All subjects were measured for foot pressure before and after exercise program intervention. We used independent t-test and one-way ANCOVA to compare the difference of foot pressure data between the exercise group and the control group. We found the exercise group in both foot pressure of hallux (T1), forefoot (M1+M2+M3), lateral midfoot (MF) were significantly better than the control group (p<0.05). It means that the intervention of 12-weeks small fit ball exercise can improve foot pressure of elderly, and make body control of elderly more stable. Therefore, 12-weeks small fit ball exercise of this study can be used as elderly falling preventive exercise.
