Vitamin D and Muscle Strength

Vitamin D and Muscle Strength

Ed, a Chattanooga fitness devotee, did 285 chin-ups trying to break a record in 2005. He quit chin ups because, as he said, they were so difficult.

Later, learning his vitamin D levels were low (12 nanograms/milliliter) he worked to raise his vitamin D levels to 40 ng/ml by January of 2007. Ed started doing chin ups again, only this time he quickly found it was much easier than before. Ed says this week (March 2007) he completed 300 chin ups “and it was almost easy!”

Ed was explaining his personal discovery about vitamin D to Dr. John Cannell, captain of the Vitamin D Council website. Dr. Cannell had just released his “Peak Athletic Performance and Vitamin D” online report. And one wonders if the next performance enhancing “drug” will be vitamin D at the 2008 Olympics.

Dr. Cannell researched medical literature going back a number of decades. He writes that the Germans and Russians who won many Olympic medals in the 1960s and 1970s were convinced vitamin D improves athletic performance. If not deficient, you may not notice any improvement, but most people have sub-optimal levels of vitamin D.

Dr. Cannell cites a 1938 study where vitamin D-producing ultraviolet lamps were used to improve 100-meter dash times from 13.63 to 12.62 seconds. A 1945 study showed that UV radiation for up to 2 minutes, three times a week, improved cardiovascular fitness scores by 19% compared to 2% in non-irradiated students in a physical education class.

Is Vit D related to getting sunshine?
So get out there and get a Tan guys.

No wonder we’ve been having problems winning medals over here in Blighty.

Maybe in the run up to 2012 we should be pro-active in increasing global warming and see our athletes performances go through the roof?

Yes. But global warming will submerge the warm currents under cold fresh glacier water and make it colder than ever there! Part of the Bush conspiracy to hog all the medals for the USA!

Was that fast in 1938? Does that mean contemporary sprinters will go from 9.77 to 8.77 seconds if they take more vitamin D?

UV light helps your body synthesize vitamins so there definitely should be benefits.

yeah I would assume the great improvement would be due to a severe deficiency, which would make sense during that time period, but I am not sure.
