本研究的主要目的是探討老年人從事不同休閒運動型態，在不同高度站立平衡控制能力效果之比較。研究以從事太極拳、網球和游泳運動的65至74歲男性老年人為實驗對象，並以 Catsys2000 平衡測量系統記錄與分析，每組各18人（共54人）進行雙足張眼站立 60秒及各組中隨機抽取6人（共18人）進行單足張眼站立 30 秒的靜態平衡控制能力，實驗參加者均須站立於平地、1/4 身高及1/2 身高等三種高度的平台測試。3×3 混合設計二因子變異數分析比較平均擺動距離、橫軸擺動距離、矢狀軸擺動距離、擺動面積、擺動速度和擺動強度等平衡控制參數，統計的顯著水準設定為 α= .05。研究結果顯示老年人雙足站立平衡控制能力，在不同休閒運動、不同站立高度均沒有顯著差異（p>.05）。在單足站立平衡控制能力方面，從事太極拳運動老人的平衡控制表現，在平均擺動距離、矢狀軸擺動距離、擺動面積、擺動速度和擺動強度等參數均優於游泳及網球運動（p<.05）。根據研究結果，雖然不同休閒運動老年人在雙足站立都有相同的控制能力，但是，本研究也建議從事網球與游泳運動的老年人應於運動期間考慮加入單足站立平衡的動作控制訓練。
The purpose of this study was to investigate the quiet balance control abilities of old people, involved in different recreational activities, at various heights. Three groups of volunteers, ranging in ages sixty-five to seventy-four, participated in Tai-Chi Quan, tennis, and swimming. Eighteen old people from each group were asked to stand using both feet with eyes open for 60 seconds. Six people from each group were chosen randomly, and asked to stand using one foot with eyes open for 30 seconds. The Catsys 2000 system was used to record and analyze the balance control abilities while the participants stood on ground, on a platform a quarter of participants’ height, and on a platform half of participants’ height. The difference for the parameters of balance control ability included: mean sway, transversal X, sagittal Y, sway area, sway velocity and sway intensity were analyzed by mixed design, 3(recreational activity)×3(treatment), two-way ANOVA with an alpha level of .05. The results of this study indicated that there was no significant difference (p>.05) between the three groups when using both feet at any height. The quiet one-foot stance balance functions included: mean sway, sagittal Y, sway area, sway velocity and sway intensity showed that those who participated in the Tai-Chi Quan exercise
were significantly better than those who participated in tennis or swimming (p<.05). These findings indicate that old people in the habit of engaging in these three recreational activities have equal balance control while standing on both feet. It suggests that old people who play tennis and swimming should consider including more one-leg balance control exercise in their program.
