An emerging body of evidence has shown the therapeutic effect of both mindful and non-mindful physical exercises on the treatment of depression. The purpose of this study is to examine the effectiveness of mindful and non-mindful physical exercises as an intervention in managing depression or depressive symptoms based on a systematic literature review.
Our review was conducted among five electronic databases to identify randomized controlled trials (RCTs), which tested the effects of mindful or/and non-mindful physical exercises on depression. Studies were classified according to the baseline depression status of participants and its relation to allocation concealment, blinding at outcome assessment, follow-up, and whether intention to treat analysis was employed.
The results based on 12 RCTs indicated that both the mindful and non-mindful physical exercises were effective in their short-term effect in reducing depression levels or depressive symptoms. However, most of studies had methodological problems that only small sample size was used, and the maintenance effects of physical exercise were not reported. Specific comparisons between RCTs on mindful and non-mindful exercises were not performed because of the limitations on the designs.
We recommend that more well-controlled studies have to be conducted in the future to address the short- and long-term effects of physical exercise on alleviating depression. Efforts should be focused on unveiling the differential effects of mindful and non-mindful exercises on depression and the underlying mechanisms of their therapeutic action.
越来越多的证据表明，正念和非正念体育锻炼对抑郁症治疗均有疗效。本研究旨在通过系统文献综述，检验正念和非正念体育锻炼作为干预措施在管理抑郁症或抑郁症状方面的有效性。
我们在五个电子数据库中进行检索，以识别随机对照试验（RCT），这些试验测试了正念或/和非正念体育锻炼对抑郁症的影响。研究根据参与者的基线抑郁状态及其与分配隐藏、结果评估时的盲法、随访以及是否采用意向性分析的关系进行分类。
基于12项随机对照试验的结果表明，正念和非正念体育锻炼在降低抑郁水平或抑郁症状方面均有短期疗效。然而，大多数研究存在方法学问题，仅使用了小样本量，且未报告体育锻炼的维持效果。由于设计上的限制，未对正念和非正念锻炼的随机对照试验进行具体比较。
我们建议未来开展更多严格控制的研究，以探讨体育锻炼对缓解抑郁的短期和长期影响。应致力于揭示正念和非正念锻炼对抑郁症的不同影响及其治疗作用的潜在机制。
