The purpose of this study was to systematically review the effects of supervised resistance training (RT) programs in people diagnosed with depression or depressive symptoms. The following databases were used to search and retrieve the articles: Cochrane Library, EBSCO, PEDro, PubMed, Scopus and Web of Science. The search was conducted in late June 2020. Search protocol required the title to contain the words depression or depressive or dysthymia. Furthermore, the title, abstract or keywords had to contain the words or expressions: "randomized controlled trial"; and "strength training" or "resistance training" or "resisted training" or "weight training". The screening provided 136 results. After the removal of duplicates, 70 records remained. Further screening of titles and abstracts resulted in the elimination of 57 papers. Therefore, 13 records were eligible for further scrutiny. Of the 13 records, nine were excluded, and the final sample consisted of four articles. Results were highly heterogeneous, with half of the studies showing positive effects of resistance training and half showing no effects. In two of the four combinations, the meta-analysis revealed significant benefits of RT in improving depressive symptoms ( ≤ 0.05). However, considering significant differences with moderate (Effect Size = 0.62) and small (ES = 0.53) effects, the heterogeneity was above 50%, thus suggesting a substantial level. To draw meaningful conclusions, future well-designed randomized controlled trials (RCTs) are needed that focus on understudied RT as a treatment for depression.
本研究旨在系统回顾监督下的抗阻训练（RT）方案对确诊抑郁症或抑郁症状人群的影响。使用以下数据库进行检索：Cochrane 图书馆、EBSCO、PEDro、PubMed、Scopus 和 Web of Science。检索于 2020 年 6 月底进行。检索方案要求标题包含“depression”“depressive”或“dysthymia”字样。此外，标题、摘要或关键词必须包含以下词汇：“randomized controlled trial”和“strength training”或“resistance training”或“resisted training”或“weight training”。筛选提供了 136 个结果。去除重复项后，仍有 70 条记录。进一步筛选标题和摘要后，排除了 57 篇论文。因此，有 13 篇记录符合进一步审查的条件。在这 13 篇记录中，有 9 篇被排除，最终样本包括 4 篇文章。结果高度异质，一半的研究显示抗阻训练有积极影响，一半则没有。在这 4 项组合中的两项中，荟萃分析显示 RT 对改善抑郁症状有显著益处（≤0.05）。然而，考虑到中等（效应量=0.62）和较小（ES=0.53）效应的显著差异，异质性超过 50%，表明存在较大水平。为得出有意义的结论，需要未来设计良好的随机对照试验（RCT）来关注研究不足的 RT 作为抑郁症的治疗方法。
