Will you take a few moments and geek out with me? If you answer no to that question, skip the next two paragraphs which I’m copying from sciencedaily.com (the whole article is here: http://bit.ly/z4urii)
The underlying genetic code in human muscle isn’t changed with exercise, but the DNA molecules within those muscles are chemically and structurally altered in very important ways. Those modifications to the DNA at precise locations appear to be early events in the genetic reprogramming of muscle for strength and, ultimately, in the structural and metabolic benefits of exercise. (Blah blah blah. This would seem significant…)
The DNA changes….known as epigenetic modifications involve the gain or loss of chemical marks ….study shows that the DNA within skeletal muscle …after a burst of exercise bears fewer chemical marks (specifically methyl groups) than it did before exercise. When the researchers made muscles contract in lab dishes, they saw a similar loss of DNA methyl groups. Exposure of isolated muscle to caffeine had the same effect.
Ok, grasshoppers… if you weren’t paying attention (or even if you were), caffeine rocks. Fix that DNA. Chew some Jolt Gum.
