目的:本研究目的是探討社區中老年人族群以健走運動方式,對其生活品質之影響。方法:本研究採類實驗性研究設計(quasi-experimental design),以方便取樣方式選取非規律運動者,分為;實驗組(健走運動介入組)計12名,對照組(未參加健走運動組)為31名。收案時間為:2007年8月至2008年5月止(共計36週)。採用SPSS 13.0版進行統計分析。結果:實驗組進行36週的運動介入活動後發現;生活品質在整體生理功能面向與整體心理功能面向得分情形普遍高於介入前的得分,其中社會功能構面達顯著改善(61.1 vs. 93.6 分, p = .007)。然而對照組一般健康狀況、活力狀況、社會功能構面與整體心理功能面向得分明顯下降,均達顯著差異;以混合設計雙因子變異數分析,顯示整體心理面向、活力狀況與社會功能具有交互作用,然後執行單純主要效果檢定可得知實驗組經運動介入後對於社會功能構面仍有正面的改善。結論:整體而言,經由36週的社區型健走運動介入能有效提升中老年人之生活品質的改善。
Purpose: This study investigated the effects of a community exercise-walking intervention on quality of life in a population of community-dwelling middle-aged and elderly individuals. Methods: Researchers used a quasi-experimental design to recruit and enroll subjects. Participation criteria excluded subjects who exercised regularly. Subjects were assigned by convenience sampling method to either an experimental group (i.e., exercise-walking intervention group, N = 12) or control group (i.e., no-exercise group, N = 31). Researchers conducted the intervention over 36 consecutive weeks between August 2007 and May 2008 and analyzed data using SPSS version 13.0 statistical software. Results: Researchers used changes in the two quality of life indicators of Physical Component Summary (PCS) and Mental Component Summary (MCS) to evaluate intervention effectiveness. Experimental group post-intervention scores were significantly higher than control group scores. The experimental group recorded a significant improvement in the Social Function indicator (61.1 vs. 93.6, p = .007), while various control group quality of life scores including General Health, Vitality, Social Function and MCS saw general declines. A mixed-design two-way ANOVA found an interaction effect among the three variables MCS, Vitality and Social Function. After conducting a simple main effect test, we found that the significantly positive effect on the Social Function indicator of the intervention remained. Conclusions: Results support the effectiveness of a 36-week community exercise-walking intervention in improving the quality of life of middle-aged and elderly in the community.
