Is vitamin D especially important for athletes?

A number of studies have shown that vitamin D improves athletic performance. How so? Vitamin D is essential for strong bones, and studies also show that it helps build muscle by increasing the size and number of the fast-twitch muscle fibers that are critical for fast and powerful movements.

More evidence that vitamin D may help athletes comes from the fact that athletic performance peaks during the summer months, when people are exposed to more sunlight and have higher levels of vitamin D in their bodies, whereas performance drops to its lowest point in the darker winter months, when people tend to have less vitamin D.
