Exercise has been shown to reduce symptoms of anxiety, but few studies have studied exercise in individuals preselected because of their high anxiety.
The objective of this study is to review and critically evaluate studies of exercise training in adults with either high levels of anxiety or an anxiety disorder.
We conducted a systematic review of randomized clinical trials (RCTs) in which anxious adults were randomized to an exercise or nonexercise control condition. Data were extracted concerning anxiety outcomes and study design. Existing meta-analyses were also reviewed.
Evidence from 12 RCTs suggested benefits of exercise, for select groups, similar to established treatments and greater than placebo. However, most studies had significant methodological limitations, including small sample sizes, concurrent therapies, and inadequate assessment of adherence and fitness levels.
Exercise may be a useful treatment for anxiety, but lack of data from rigorous, methodologically sound RCTs precludes any definitive conclusions about its effectiveness.
运动已被证明可减轻焦虑症状，但很少有研究针对因焦虑水平高而预先选定的个体进行运动研究。
本研究的目的是回顾并批判性地评估针对焦虑水平高或患有焦虑症的成年人进行运动训练的研究。
我们对随机临床试验（RCT）进行了系统回顾，其中焦虑的成年人被随机分配到运动组或非运动对照组。提取了有关焦虑结果和研究设计的数据。还回顾了现有的荟萃分析。
12项随机对照试验的证据表明，运动对特定群体有益，类似于既定治疗方法，且优于安慰剂。然而，大多数研究存在重大方法学局限性，包括样本量小、同时进行的疗法以及对依从性和健康水平的评估不足。
运动可能是治疗焦虑的有效方法，但缺乏来自严格、方法合理的随机对照试验的数据，无法就其有效性得出任何明确结论。
