CAN VITAMIN D MAKE YOU A BETTER RUNNER?

Vitamin D Replacement Improves Muscle Efficiency

From The ScienceDaily:

A new study shows for the first time a link between vitamin D and muscle efficiency. The findings may explain the fatigue often felt by patients with vitamin D deficiency.

Researchers in the UK investigated phosphocreatine recovery times in patients with vitamin D deficiency. They used magnetic resonance scan to measure phosphocreatine dynamics in response to exercise in the calf muscles of 12 patients with severe vitamin D deficiency before and after treatment with vitamin D. This is the first time a study of this kind has been conducted.

The team found that phosphocreatine recovery significantly improved after the patients took a fixed dose of oral vitamin D for 10-12 weeks. All patients reported an improvement in symptoms of fatigue following supplementation. In a parallel study, the group demonstrated that low Vitamin D levels were associated with reduced mitochondrial function.

The research shows for the first time that vitamin D levels are correlated with muscle efficiency, and that muscle aerobic metabolism improves with Vitamin D supplementation. The mechanisms underpinning this effect are an avenue for future research by the group, who also aim to establish whether vitamin D supplementation could alleviate frailty in the elderly or improve the exercise capacity of athletes.
