規律運動對老年女性在平地行走與上下階梯的影響

Abstract

目的：藉由平地行走、上下階梯三種日常生活動作，了解規律運動對老年女性在平衡控制上的差異。方法：本研究是以20名65~75歲之健康老年女性，分為規律運動組(平均年齡：67.20±2.53歲)與非規律運動組(平均年齡：67.10±3.35歲)為受試者，以三維動作分析系統擷取老年女性平地行走與上下階梯之動作數據，以測力板同步收取足底壓力中心。以二因子混和設計區分有無規律運動與不同動作(平地行走與上下階梯)對老年女性的平衡控制上是否有差異，顯著水準為α = .05。結果：規律運動組與非規律運動組在各項參數上均無差異。但在不同動作上，平地行走之前後方向之身體質心移動範圍與身體質心速度為三種動作中最高(p<.05)；下階梯之左右方向身體質心移動範圍與身體質心速度為三種動作中最高(p<.05)，但左右方向之壓力中心移動範圍為三種動作中最小(p<.05)。結論：根據本研究的分類，有無規律運動不會影響老年女性的平衡控制表現。Purpose: To compare the effect of regular exercise for female elders by balance control during walking, stair ascent and decent. Method: 20 healthy female elders (age: 65~75) were divided into exercise group (age: 67.20±2.53) and non-exercise group (age:67.10±3.35). A 3D motion analysis system was used to capture and record movements of the elderly female participants during walking, stair ascent and decent. And a force platform was used to collect the data of center of pressure synchronously. The different in parameters were tested by two way mix design ANOVA, the significant level was as α = .05. Result: There were non-significant differences between two groups during walking, stair ascent and decent. But, there were significant differences among movements (walking, stair ascent and decent). Anterior-posterior direction of COM displacement and COM velocity was greater during walking (p<.05). Medial-lateral direction of COM displacement and COM velocity was greater (p<.05) and medial-lateral of COP displacement was smaller during stair decent (p<.05). Conclusion: Based on the criterion of dividing the groups, the regular exercise did not have the effect on the ability of balance control for female elders.
