18週下肢閉鎖式運動對高齡者行走能力與健康效益之初步探討－以台中市某社區為例

緒論：老化是必然的過程，尤其是下肢肌力退化；容易造成行走表現下降，進而影響生活品質。因此，老年人應該從事可提升行走能力與健康的體適能訓練，來提高生活品質。故本研究將介入18週的下肢閉鎖式運動來探討運動介入後對高齡者的行走能力與健康效益的影響。方法：招募40位65歲以上的高齡者，男性27位、女性13位，在介入18週下肢閉鎖式運動訓練之前、後進行行走效能及身體健康指標檢測，包身高、體重、身體質量指數、腰圍、臀圍及下肢肌力測試和10公尺行走測試，以成對樣本t-test比較之差異。結果：高齡者以下肢閉鎖式運動進行18週後其行走效能方面有明顯改善。研究對象在10公尺步行測試達到統計上顯著差異(p＜.05)，徒手下肢肌力測試則沒有差異；而在收縮壓、舒張壓、身體質量指數、腰圍、臀圍項目方面其前、後測亦無差異。結論：下肢閉鎖式運動對於高齡者的行走能力與健康狀況確實有幫助，期望未來可作為高齡者運動指導之參考。

Introduction: Aging is an essential process, especially the muscle strength of lower extremities gradually decline. It reduces the walking ability and quality of life. Therefore, Older should do fitness training which improves the walk ability and life quality. The purpose of the investigation was to research the effect of eighteen-week lower extremities close-chain exercise for elders' walking ability and health condition. Method: Recruited 40 elders whose ages were above 65, 27 males and 13 females. Before and after intervention, we evaluated their walking ability and health condition, including systolic pressure, diastolic pressure, weight, body mass index (BMI), waist circumference, hip circumference, muscle strength of lower extremities and 10 meters walking test. We analyzed the differences by paired t-test. Results: The walking ability improved after eighteen-week intervention. The walking ability was statistically significant. (p＜.05). In lower extremities muscle strength was no significant differences. Also, there was no statistically significant relationship between systolic pressure, diastolic pressure, weight, BMI, waist circumference, and hip circumference. Conclusion: Eighteen-week lower extremities close-chain exercise was really helpful for elder's walking ability and health condition. We hope that the program could be the reference of instruction of the elder's exercise.
