Training Is In Your Genes

More energy. Better weight management. A leaner physique. Regular training does a lot for you. But what does consistent long-term training do for your body at the gene level? Scientists from Victoria University in Australia wanted to know. So they performed gene microarray analysis on well-trained endurance athletes, strength athletes and a control group of coach potatoes. 263 genes were expressed differently between trained and untrained subjects. Only 21 genes were different between the endurance and strength athletes.

The Bigger Picture: This study shows how the body co-regulates genes over an extended time period to adapt to the rigors of consistent exercise. It also underscores the importance of changing your routine every 6 to 8 weeks or so. If you favor strength training, try running for a change of pace. If you're the kind of person who bikes 30 miles a day, see what develops under a set of plates.
