Comparative Efficacy of Acute Exercise Intervention on Anxiety in Adolescents and Young Adults: A Network Meta‐Analysis

ABSTRACT Acute exercise is a promising non‐pharmacological therapy for alleviating anxiety. However, the effects of different types of acute exercise on anxiety in adolescents and young adults remain unclear. Therefore, our study aims to conduct a network meta‐analysis to compare the effectiveness of various exercise interventions in improving anxiety in adolescents and young adults. We conducted an online literature search in five databases: PubMed, Web of Science, Embase, Cochrane Central Register of Controlled Trials, and PsycINFO. The search was conducted from inception to March 1, 2023, and was limited to English‐language publications. Pairwise and network meta‐analyses were performed using random‐effects models. The Grading of Recommendations Assessment, Development, and Evaluation (GRADE) framework was applied to rate the certainty of evidence. A total of 33 studies involving 1121 participants were included. The network meta‐analysis results revealed that mind–body exercise was the most effective intervention for reducing anxiety in adolescents and young adults (SMD = −0.36, 95% CI: −0.70, −0.03, moderate certainty). Additionally, aerobic exercise (SMD = −0.16, 95% CI: −0.28, −0.03, high certainty) showed significant reduction in anxiety, while resistance exercise (SMD = −0.09, 95% CI: −0.33, 0.14, moderate certainty) and multicomponent exercise (SMD = −0.01, 95% CI: −0.59, 0.57, moderate certainty) did not show significant reduction in anxiety. Moderate certainty evidence suggests that acute mind–body exercise may be the most effective type of exercise for reducing anxiety in adolescents and young adults. Future research should focus on conducting more multi‐arm randomized controlled trials to provide more direct evidence on the relative effectiveness of different exercise interventions.
