目的：本研究針對社區中老年人進行運動介入，以了解運動介入對生理、心理和記憶功能的影響。方法：本研究共招募16位55歲以上社區的中老年人（運動組），參與24週，每週一次，一次90分鐘的社區型團體運動介入，並招募未參與團體運動之控制組(13人)。兩組於介入前後、進行生理體能評估、心理功能（活動量和生活品質）、和記憶力的評估。結果：分析組內比較結果顯示，在部分生理指標、記憶力、生活品質項目，運動組相較於控制組有顯著地改善 (ps < .025)，但在其他生理、記憶評估並未見顯著差異。結論：本研究結果顯示社區型團體運動可增進社區中老年人的生理、記憶、心理功能，但成效可能受頻率、強度、及個人生活環境因素影響。

Objective: The purpose of this study was to assess the effects of a community-based group exercise program on the physical, psychological, and memory functions in middle-aged and elderly population. Methods: A total of 16 participants were enrolled in the community-based exercise training group as the experimental group. The exercise training program was 90 minutes once a week for a total of 24 weeks. Thirteen community residents, who did not participate in any kind of exercise program, volunteered to participate in the control group and maintained their daily routine during the study. Both groups were tested with physical, psychological, and memory functions at the baseline phase, the middle and the end of the program. Two-way repeated measured analysis of variance was used to examine the group and time effects. Paired t test were used within each group to analyze the change in the middle and the end of the program. Results: The experimental group had significant improvement on the waist and hip measures, the strength of lower body, immediate and delayed memory, and some domains in SF-36 (ps < .05). Conclusion: This study supports that the effects of the 24-weeks community exercise group, in a regimen of 90 minutes session, once a week, can improve the physical function, memory, and quality of life in the middle-aged and elderly population.
