Physical activity in green and blue spaces provide physical and mental health benefits in populations of all ages. In this study, we explored the effectiveness of longer-term green and blue physical activity of improving the quality of life. Medline, Pubmed, Embase, and Web of Science databases were searched in September 2020. A systematic review and meta-analysis were conducted using a random-effects model. Moderator analyses were performed to investigate differences in effect sizes. In total, eight randomized controlled trials (RCTs) were selected for a qualitative and quantitative synthesis of quality of life outcomes. Results showed significant increased effects of green and blue physical activity interventions on physical and mental health compared to a control group, but an insignificant effect on the general quality of life. A moderator analysis and meta-regression indicated that the mean age of the experimental group had a significant effect on mental health. This first meta-analysis of RCTs found multiple instances of green and blue physical activity being beneficial to physical and mental health. Engaging in physical activity in green and blue spaces is advocated to improve the quality of life of individuals, health practitioners, urban planning, and policymakers.

绿色和蓝色空间中的体育活动可为所有年龄段的人群提供身心健康方面的好处。在这项研究中，我们探索了长期的绿色和蓝色体育锻炼对改善生活质量的有效性。2020年9月对Medline，Pubmed，Embase和Web of Science数据库进行了搜索。使用随机效应模型进行了系统的综述和荟萃分析。进行主持人分析以研究效应大小的差异。总共选择了八项随机对照试验（RCT），以对生活质量的结果进行定性和定量综合。结果显示，与对照组相比，绿色和蓝色体育锻炼干预对身心健康的影响显着增加，但对总体生活质量的影响却很小。主持人分析和荟萃回归表明，实验组的平均年龄对心理健康有显着影响。首次对RCT进行荟萃分析，发现绿色和蓝色体育活动的多个实例有益于身心健康。提倡在绿色和蓝色空间从事体育活动，以提高个人，卫生从业人员，城市规划和政策制定者的生活质量。
