Summary: While the benefits of physical activity on mental health are well-known, systematic reviews and meta-analyses on its impact on mental illness in adults with COVID-19 are scarce. This study of 25 randomized controlled trials shows that physical activity significantly reduces anxiety (standardized mean difference [SMD] = −0.915; 95% confidence interval [CI] = −1.182 to −0.648; I2 = 82.0%; p < 0.001) and depression (SMD = −0.752; 95% CI = −1.034 to −0.470; I2 = 81.4%; p < 0.001). Traditional Chinese ethnic sports are notably effective. Interventions under 3 weeks best reduce depression, while 3 ≤ 7 weeks optimally reduce anxiety. Sessions ≤5 times weekly, with 30 ≤ 60 min for anxiety and >60 min for depression, yield the best outcomes. These results highlight the specific effectiveness of physical activity in alleviating anxiety and depression in COVID-19 patients.
