Abstract
BACKGROUND: Physical and mental health problems are becoming more serious among college students due to lifestyle changes and increased academic stress. Qigong exercise has been regarded as a potentially effective intervention to improve the physical and mental health of college students. METHODS: Eleven databases were searched from their respective inception dates to April 2022. Relevant randomized controlled trials (RCTs) were included. Physical and psychological conditions, including limb muscle strength, flexibility, cardiorespiratory endurance, vital capacity, blood pressure and heart rate, as well as depression, anxiety and mood, were evaluated. The risk of bias was assessed with the Cochrane Collaboration tool. RESULTS: Sixteen randomized controlled trials were included in the meta-analysis. Significant improvements in cardiorespiratory endurance (MD = 3.83, 95% CI: 0.99 to 6.67, P = 0.008) and flexibility (MD = 3.01, 95% CI: 1.21 to 4.81, P = 0.001) were observed. We also observed that Qigong exercise significantly reduced depression and anxiety symptoms (SMD=-0.89, 95% CI: -1.17 to -0.61, P < 0.00001; SMD=-0.78, 95% CI: -1.31 to -0.25, P = 0.004). Nevertheless, no significant effects on muscle strength, vital capacity, blood pressure, heart rate or mood were found. CONCLUSION: Qigong exercise was advantageous for college students in terms of improving flexibility and cardiorespiratory endurance and alleviating depression and anxiety to some extent. However, due to the limited number of eligible trials and the low methodological quality, more well-designed RCTs are needed in the future.
