Does Vitamin D Affect Strength?

This week, I want to share an interesting finding involving Vitamin D deficiency in elite Danish swimmers.

Most people with a basic understanding of nutrition know that Vitamin D is very important for bone health and metabolism. However, the discovery of Vitamin D receptors in muscle cells may indicate that it may also play a role in muscle contraction and athletic performance.

Recently, a study conducted on elite Danish swimmers reported an association between Vitamin D status and muscular strength. The main finding was that muscular strength as assessed by hand grip, was significantly higher in swimmers with sufficient Vitamin D status.

Now the most common way to get Vitamin D is through direct exposure to ultraviolet radiation from the sun, the rest having to come through diet and supplementation. Now I find this interesting, because it’s not uncommon for the sun to take a vacation for a while during Canadian winters. In addition, with swimmers training indoors for hours a day, they might find it especially difficult to meet their daily requirements during the winter months.
