Objectives: To integrate and explore the effects of exercise on depression in older people by a systematic literature review and meta-analysis. Methods: The electronic databases PubMed, CINAHL, Cochrane Library, Index to Taiwan Periodical Literature System, and National Digital Library of Thesis and Dissertations were searched for articles published between 2004 and 2019 in Taiwan. This study used the level of evidence outlined in the article by Melnyk and Fineout- Overholt (2005) for the interventional study. A meta-analysis was applied using the RevMan 5.3 to examine the effects of the exercise interventions on depression in older people. Results: This study included 13 articles in the analysis. In total, 1477 participants (exercise: 720; control: 757, 95% confidence interval [-0.45, -0.10], Z = 3.14, p = 0.002) showed a combined effect of -0.27, indicating that exercise intervention could improve the degree of depression in older people. According to the subgroup analysis, the intervention time is 'two or three times a week for at least 24 weeks', and the participant belongs to the 'elderly community,' which can effectively alleviate the degree of depression. Conclusions: Exercise can improve the degree of depression in older people. The recommended exercise protocol of older people in the community is that it should last for 'at least 24 weeks', and include 'exercise twice or three times a week' to alleviate their depression. More empirical studies are suggested in the future to provide a clearer analysis and discuss the factors of types of activity interventions, duration of exercise interventions, number of weekly interventions, and demographic characteristics (race, age, and degrees of depression).
