Abstract：
OBJECTIVE: To determine the treatment effect of resistance training in reducing symptoms of anxiety and depression in young people.
METHODS: We searched MEDLINE, PsychINFO, and PubMed for articles published in English from January 1980 to September 2023 for randomized controlled trials (RCT) that included at least 4 weeks of resistance training, with participants aged 26 years or younger with clinically elevated anxiety and depression symptoms. A random-effects meta-analysis was used to calculate a pooled effect size of resistance training pre-and post-intervention compared to control groups. The quality of evidence was assessed using the Cochrane risk-of-bias 2 (RoB 2) and Grading of Recommendation, Assessment, Development, and Evaluation (GRADE) criteria.
RESULTS: Ten RCTs involving 376 participants (209 females and 127 males) across educational, clinical, and community based setting were eligible for inclusion in the analysis. Resistance training was associated with a significant reduction in depressive (Hedge\'s g = -1.06, 95% CI -1.61 to -0.51, p < .001) and anxiety (Hedge\'s g = -1.02, 95% CI -1.50 to -0.54, p < .001) symptoms. Substantial heterogeneity was observed in the analysis of depression symptoms (I2 = 79%) and anxiety symptoms (I2 = 66%). Six trials had a low risk of bias, four trials showed some concerns. The GRADE analysis demonstrated a high level of certainty for depressive symptoms and a moderate level for anxiety symptoms.
CONCLUSIONS: Resistance training is an effective intervention in reducing depression and anxiety symptoms in young people, delivered across a range of settings. Future trials exploring the effect resistance training interventions with long-term follow up are warranted to understand the outcomes.

摘要：
目的：探讨抗阻训练对减轻青少年焦虑、抑郁症状的治疗效果。
方法：我们搜索了MEDLINE，心理信息,和PubMed从1980年1月至2023年9月以英文发表的关于随机对照试验（RCT）的文章，其中包括至少4周的阻力训练，受试者年龄在26岁或以下，焦虑和抑郁症状临床升高。与对照组相比，使用随机效应荟萃分析来计算干预前后阻力训练的汇总效应大小。使用Cochrane偏见风险2（RoB2）和建议分级评估证据质量，评估,发展,和评估（等级）标准。
结果：十个RCT，涉及376名参与者（209名女性和127名男性），临床,基于社区的环境符合纳入分析的条件.阻力训练与抑郁(Hedge'sg=-1.06,95%CI-1.61至-0.51,p<.001)和焦虑(Hedge'sg=-1.02,95%CI-1.50至-0.54,p<.001)症状的显著减少相关。在抑郁症状（I2=79％）和焦虑症状（I2=66％）的分析中观察到了很大的异质性。六项试验的偏倚风险很低，四项试验显示了一些担忧。GRADE分析显示抑郁症状的确定性很高，焦虑症状的确定性为中等水平。
结论:抗阻训练是减轻青少年抑郁和焦虑症状的有效干预措施,在一系列设置中交付。未来的试验探索阻力训练干预的效果与长期随访是必要的，以了解结果。
