ETS Tanning Bed Blog

This month, the American College of Sports Medicine published an article in their Medicine & Science in Sports & Exercise journal that says vitamin D can actually help athletic performance .

While a few sessions of indoor tanning isn't going to turn you into Shawn Johnson or Michael Phelps, the article, titled 'Athletic Performance and Vitamin D' , found that because vitamin D is actually a steroid hormone that regulates over a thousand vitamin D-responsive genes, it may postively affect athletic performance. The article cited a number of studies, including a German study that found increased exposure to UV-B rays improves athletic performance.

Other cited studies found that athletic performance peaks seasonally with those peaks corresponding to prolonged exposure to sunshine, UV-B rays and vitamin D. Another study mentioned in the article found that regular sunshine and optimal vitamin D levels can actually increase the number and size of Type II muscle fibers - the muscle fibers known as our "fast twitch" fibers which are key for athletes.

Athletes who already participate in outdoor sports — long-distance runners, cyclists, baseball players and soccer players — have plenty of vitamin D, but it's the indoor and winter athletes who could probably use the extra vitamin D boost to aid their performance.

And because vitamin D deficiencies can actually be dangerous for an athlete (for all of us, actually), resulting in bone loss, increased risk of injury and a weakened immune system, it's critical that these sports enthusiasts keep a close eye on their vitamin D levels.

So, what does this mean for our Olympic athletes? Will we see our luge and speed skating teams preparing for Vancouver 2010 with indoor tanning sessions and lots of sunshine? Maybe. I can tell you this much - sunshine and UV-B rays aren't illegal.
