The Effect of Taekwondo on Depression: A Meta-Analysis

Depression is a prevalent mental health disorder with adverse effects on both physical and psychological health. Taekwondo is posited to exert a positive influence on depression, yet its efficacy warrants further verification.

This study employed meta-analysis to quantify the intervention effect of Taekwondo on depression. Concurrently, based on subgroup analysis results, an optimal intervention program was suggested. Multiple databases were searched, including English (Web of Science, PubMed), Chinese (CNKI, WANFANG DATA), and Korean (RISS, KISS, DBPIA), to retrieve randomized controlled trials (RCTs) studying Taekwondo's impact on depression, published up to Jan 2024. The Cochrane bias risk tool version 2 (RoB 2.0) was utilized for literature bias risk assessment. Comprehensive Meta-Analysis software facilitated the meta-analysis, subgroup analysis, and publication bias evaluation.

Fifteen articles, encompassing 1945 participants, were included in the study. The primary findings indicated a significant reduction in depression risk due to Taekwondo intervention (Effect Size [ES]=-0.635, P<0.001). Subgroup analysis revealed the most substantial intervention effects in elderly individuals (ES=-1.025, P=0.004) and women (ES=-1.114, P=0.009). Taekwondo exercises, when conducted over 12 wk (ES=-0.922, P<0.001), three times per week (ES=-0.729, P<0.001), for 60 min per session (ES=-0.980, P=0.003), and at low intensity (ES= -1.777, P=0.024), yielded the greatest depression mitigation effects.

Taekwondo is an effective means to alleviate depression, particularly in older women. The study recommends a low-intensity Taekwondo exercise regimen, consisting of 60-minute sessions, three times weekly for 12 wk, as an optimal exercise prescription for best outcomes.
