Do Post-Exercise Hormones Increase Muscle Strength?


Working out may boost your testosterone and growth hormone naturally, but does that lead to increased muscle strength?

Not according to two new studies by researchers at McMaster University. While the levels of those hormones in the blood do jump after resistance exercise, they don’t play a large role in stimulating muscle growth.

 In one study, published in Journal of Applied Physiology, the researchers looked at the difference between men and women after intense resistance leg exercise. Men, of course, showed a much larger increase in their testosterone—45 times greater.

The muscles of both men and women, however, built new muscle proteins at about the same pace.
