What happens to the body with “detraining”?
During “detraining”, the body suffers a decrease in the cross-sectional area of the muscle fibers, becoming visible after only a couple of weeks of inactivity. Strength loss also occurs largely due to the degeneration of motor units. Detraining also causes the body’s natural testosterone levels to fall. Sometimes headaches, insomnia, feelings of exhaustion, loss of appetite, increased tension, mood disturbances, and depression also accompany total abstinence of training due to the lowered levels of testosterone and beta-endorphin.
