Abstract:


The prevalence of vitamin D insufficiency in athletes is concerning due to the potential negative effects on physical performance. The concept that vitamin D status positively correlates with measures of muscular strength and cardiorespiratory fitness is receiving increased interest among a wide range of athletes. We reviewed published studies that examined the association of vitamin D status with, and the effect of vitamin D supplementation on measures of athletic performance. An increased vitamin D status was associated with improved athletic performance in only one observational study. Several intervention studies demonstrated that the improvement in muscular strength occurs when athletes with low vitamin D status are restored to vitamin D sufficient status. Further research in various athletic populations is needed to establish the role of vitamin D in athletic performance and optimal vitamin D status in athletes.
