Abstract:
OBJECTIVES: Exercise has been promoted as a treatment for a variety of psychiatric conditions. The benefits of exercise for depression are widely recognized, but the benefits of exercise for anxiety are uncertain. Although several reviews promoted exercise as a treatment for anxiety, concerns about the quality of studies prompted us to provide a critical review of the recent literature to re-assess the value of exercise for treating anxiety. METHODS AND MATERIALS: We conducted a systematic review of all peer-reviewed randomized clinical trials (RCTs) among adults, published between January 2014 and December 2021, with an exercise intervention and anxiety as the a priori primary outcome. Two reviewers independently extracted data from studies meeting inclusion criteria, including sample characteristics, exercise intervention, control conditions, primary anxiety measure, relevant findings, and methodological quality quantified by PEDro scores. RESULTS: 7240 published studies from CINAHL, EMBASE, MEDLINE, and PsycINFO were screened in April 2022, with 1831 participants across 25 eligible RCTs, of which 13 included elevated anxiety at study entry as an eligibility criterion. Only two of these 13 studies, and five of 12 studies of non-anxious individuals, found anxiety to be reduced unequivocally with exercise. Most studies suffered from significant methodological limitations including concurrent therapies and lack of intention-to-treat analyses. CONCLUSION: There remains considerable uncertainty about the value of exercise in reducing symptoms of anxiety, particularly among anxious individuals. The paucity of methodologically sound studies of patients with anxiety represents a significant gap in our knowledge and calls for more research in the area. Word count: 249.
