Effect of a mindfulness programme training to prevent the sport injury and improve the performance of semi-professional soccer players.

OBJECTIVE: Mindfulness improves psychological outcomes. We examined whether greater mindfulness scores were associated with reduced injury rates in soccer players, as well as improved performance at both the individual and team level. METHOD: This was a parallel-group, pre- and post-test, randomised controlled pilot trial. Forty-five male amateur soccer players from Tehran, Iran, were randomly assigned into experimental (n=23) and control groups (n=22). Outcomes were scores on the mindfulness sport inventory, as well as injury rates and recovery as assessed by a physiotherapist using standardised criteria. Expert observers assessed the effect on individual and team performance. Data were analysed using mixed analysis of variance and, where indicated, its non-parametric alternative, the Friedman test. RESULTS: Significantly greater mindfulness scores in the intervention group were associated with both reduced injury and improved performance. CONCLUSION: Mindfulness training shows promise in preventing injury and improving performance. The intervention could be applied to other sports and be helpful in clinical settings given the importance of exercise in promoting psychological well-being.
