虽然许多初步研究已经证明了身体活动（PA）的心理健康益处，但以前没有定量综合研究过增加PA的干预措施的焦虑结果。这项荟萃分析整合了现有的研究，从干预措施，以增加健康成人中的PA焦虑的结果。广泛的文献检索定位了已发表和未发表的具有焦虑结局的PA干预研究。符合条件的研究报告了旨在增加无焦虑症的健康成人PA的干预措施的结果。数据编码来自主要研究。完成随机效应荟萃分析程序。采用荟萃分析ANOVA和回归模拟进行探索性调节分析，以确定报告、方法、样本或干预特征是否与焦虑结局差异相关。对来自19份合格报告的3，289例受试者的数据进行了综合。两组比较的总体平均焦虑效应量（d指数）为0.22，具有显著异质性（Q = 32.15）。探索性主持人分析发现，在包括较大样本的研究中，焦虑改善效应量较大，将受试者随机分配至治疗和对照条件，仅针对PA行为而不是多种健康行为，包括监督锻炼（与家庭PA），使用中等或高强度而不是低强度PA，并建议受试者在干预后在健身设施（与家庭）锻炼。这些研究结果表明，一些干预措施可以减少健康成年人的焦虑症状。探索性调节分析为未来的主要研究提供了可能的方向，以比较随机试验中的干预措施，以确认因果关系。
Although numerous primary studies have documented the mental health benefits of physical activity (PA), no previous quantitative synthesis has examined anxiety outcomes of interventions to increase PA. This meta-analysis integrates extant research about anxiety outcomes from interventions to increase PA among healthy adults. Extensive literature searching located published and unpublished PA intervention studies with anxiety outcomes. Eligible studies reported findings from interventions designed to increase PA delivered to healthy adults without anxiety disorders. Data were coded from primary studies. Random-effects meta-analytic procedures were completed. Exploratory moderator analyses using meta-analysis ANOVA and regression analogues were conducted to determine if report, methods, sample, or intervention characteristics were associated with differences in anxiety outcomes. Data were synthesized across 3,289 subjects from 19 eligible reports. The overall mean anxiety effect size (d-index) for two-group comparisons was 0.22 with significant heterogeneity (Q = 32.15). Exploratory moderator analyses found larger anxiety improvement effect sizes among studies that included larger samples, used random allocation of subjects to treatment and control conditions, targeted only PA behavior instead of multiple health behaviors, included supervised exercise (vs. home-based PA), used moderate or high-intensity instead of low-intensity PA, and suggested subjects exercise at a fitness facility (vs. home) following interventions. These findings document that some interventions can decrease anxiety symptoms among healthy adults. Exploratory moderator analyses suggest possible directions for future primary research to compare interventions in randomized trials to confirm causal relationships.
