摘要

目的：探討有無運動經驗之停經後女性進行團體階梯有氧（GBSA）運動對身體組成與身體功能之影響。方法：已停經且未服用雌激素之健康女性33人（年齡55-70歲）分成有運動經驗組（EGE，9人）、無運動經驗組（EGN，11人）及控制組（CG，13人）。EGE在本研究前4個月內曾接受10週運動介入；本實驗期間EGE與EGN接受中高強度之GBSA介入10週（3次／週、90分鐘／次），CG則不做介入。結果：10週GBSA介入後，EGE與EGN在坐姿起立、2公里走路指數皆顯著優於CG（p＜.05）；EGN在10週坐姿起立之進步率（30.7%）顯著優於EGE（9.7%）與CG（-4.6%）；身體組成無差異。結論：10週運動參與對身體組成無影響，但可顯著提升有運動經驗組及無運動經驗組停經後女性的身體功能表現，其中有運動經驗組在下肢肌力的提升效益高於無運動經驗組。

Purpose: To investigate the effects of group-based step aerobic (GBSA) training on body composition and physical function in postmenopausal women (PMW) with or without exercise experience. Methods: Thirty-three healthy menopaused women (age: 55-70 yrs) without hormone replacement therapy were designated into exercise group with experience (EGE, n=9), exercise group with non-experience (EGN, n=11), and control group (CG, n=13). EGE had experienced 10 weeks exercise program within 4 months before the study. In the study, EGE and EGN performed 90 min of GBSA program 3 times/week for 10 weeks at high-intermediate intensity; CG maintained their regular lifestyle. Body composition (measured by DXA) and physical function (chair-stand test [CS], and 2-km walk test [2KW]) were tested at baseline and 10th week. Results: After 10-week GBSA intervention, the performance of CS and 2KW index both in EGE and EGE were significantly better than that in CG. The change rate of CS in EGN (30.65%) was significantly improved than those in EGE (9.7%) and in CG (-4.6%). There was no difference in body composition. Conclusion: The 10-week GBSA program significantly improves strength of lower extremities and cardiorespiratory endurance in PMW both with and without exercise experience, meanwhile the enhance rate (effective) of the strength of lower extremities in non-exercise experienced PMW was better.
