Background: Emerging evidence indicates that the provision or experience of “variety” may be an important determinant of physical activity behavior. Variety refers to diverse endeavors, opportunities, or tasks and, in the context of physical activity, has been examined as a feature of an activity or environment (i.e., variety support) and an experience (i.e., one’s felt experience or perceived variety). Objective: The primary aim of our review was to synthesize studies investigating the provision or experience of variety in physical activity settings on health and well-being, behaviors, and motivation. Our secondary aim was to examine quantitative data reporting on different facets of variety in physical activity settings. Methods: We conducted a systematic search of five electronic databases (Scopus, SPORTDiscus, Science Direct, MEDLINE, and the Human Kinetics Library) to identify studies providing a quantitative or qualitative assessment of variety in physical activity settings. Results: We identified 5,576 potentially relevant articles to examine. After title and abstract screening (and removal of duplicates), 74 articles remained for full-text screening, from which 28 studies were deemed eligible. Our findings from qualitative and quantitative (experimental and cross-sectional) studies demonstrate that the provision and experience of variety relates to participation and engagement in physical activity, motivation for exercise and physical activity, and well-being outcomes. Our results also indicate that the provision of variety can increase enjoyment, interest (i.e., motivation), and adherence to a physical activity program. Conclusion: Our findings support the assertion that variety should be considered during planning, implementation, and evaluation of physical activity programs. Additional experimental studies are needed to gain a better understanding of how elements of physical activity and exercise programs, delivery, and environment can be manipulated to increase variety and foster participation in physical activity.

背景：新出现的证据表明，“多样性”的提供或体验可能是身体活动行为的重要决定因素。多样性是指不同的努力、机会或任务，在体育活动的背景下，多样性已被视为活动或环境（即多样性支持）和体验（即一个人的感受体验或感知多样性）的特征。 目的： 我们审查的主要目的是综合研究调查在健康和福祉、行为和动机方面提供或体验各种体育活动设置。我们的次要目标是检查有关身体活动环境中多样性不同方面的定量数据报告。方法：我们对五个电子数据库（Scopus、SPORTDiscus、Science Direct、MEDLINE 和 Human Kinetics Library）进行了系统搜索，以确定对体育活动设置的多样性进行定量或定性评估的研究。结果： 我们确定了 5,576 篇可能相关的文章进行检查。经过标题和摘要筛选（并删除重复项）后，仍有 74 篇文章需要进行全文筛选，其中 28 项研究被认为符合条件。我们的定性和定量（实验和横断面）研究结果表明，多样性的提供和体验与身体活动的参与和参与、锻炼和身体活动的动机以及幸福感结果有关。我们的结果还表明，提供多样性可以增加乐趣、兴趣（即动力）和坚持体育活动计划。结论： 我们的研究结果支持这样的断言，即在体育活动计划的规划、实施和评估过程中应考虑多样性。需要进行更多的实验研究，以更好地了解如何操纵身体活动和锻炼计划、交付和环境的要素，以增加多样性和促进身体活动的参与。
