Blood levels of anabolic (tissue building) and catabolic (tissue breakdown) hormones change during and after vigorous weight-training workouts.
Adrenaline (epinephrine), testosterone and growth hormone, for example, increase when you train hard, but quickly subside after the workout is over. Insulin receptors are extremely sensitive during the first hour of recovery from a workout. These changes, while temporary, may be important for increasing strength following workouts. The structure of the program and the timing of supplement intake determine your capacity to harness these hormone changes to build strength. Small changes in testosterone or muscle growth factors don’t translate immediately into more muscle, but harnessing them systematically every workout may make a difference over months and years of training. Canadian researchers found that increases in anabolic hormones weren’t necessary to build strength. They measured the effects of eight weeks of unilateral weight training (leg press and knee extensions) on muscle building, using the inactive leg as the control. Training increased the size of fast-twitch fibers and total muscle cross-sectional area in the active muscle, with no changes in anabolic or catabolic hormones. The importance of hormone changes during intense weight training is unknown. (European Journal Applied Physiology, 98: 546-555, 2006)
