This review article found a strong correlation between vitamin D sufficiency and optimal muscle function. They found that increasing levels of vitamin D reduced inflammation, pain, and myopathy while increasing muscle protein synthesis, ATP concentration, strength, jump height, jump velocity, jump power, exercise capacity, and physical performance.

This double-blind placebo-controlled study in ultra-marathon runners found that supplementation with 2000 IU of vitamin D daily decreased post-exercise skeletal muscle biomarkers levels including post-exercise (TN max) and 1 h post-exercise troponin, 1 h post-exercise myoglobin concentration, and TNF-α levels. 24 hour post exercise creatine kinase activity was also significantly lower in the supplemented group compared to the placebo. This suggests that vitamin D supplementation might play an important role in prevention of skeletal muscle injuries following exercise with eccentric muscle contraction in athletes.

This study of elite ballet dancers found that supplementation with 2000 IU of vitamin D daily for 4 months improved strength and jump height and reduced risk of injury. Significant increases were noted for the intervention group for isometric strength (18.7%) and vertical jump (7.1%). The intervention group also sustained significantly less injuries than the controls during the study period.

This review of 11 studies found that vitamin D supplementation for periods of more than 1 week with a minimum dose of 2000 IU/day appears to be an effective strategy for attenuating muscle damage and inflammation after exercise.

Journal of Sports Sciences
This placebo-controlled study that gave athletes and healthy non-athletes 5000 IU of vitamin D per day for 8 weeks found that there was a significant increase in 10 m sprint times and vertical-jump in the vitamin D group whereas the placebo showed no change. This suggests that inadequate vitamin D concentration may be detrimental to musculoskeletal performance in athletes.

This review explores how vitamin D plays an important role in the bidirectional relationship observed between sleep and pain. The authors conclude that supplementation of vitamin D may have a therapeutic role, not only in sleep disorders but also in the prevention and treatment of chronic pain conditions.

Nutrition Research Reviews
This review describes the molecular role of vitamin D in skeletal muscle tissue function and metabolism, specifically in relation to proliferation, differentiation and the protein synthesis processes. Substantial evidence suggests that vitamin D may have the potential to modulate protein synthesis, mitochondrial metabolism as well as energy production, which is likely to make an impact on muscle strength, function and performance.
