Doing research on GH-IGF axis may elucidate further the mechanism of training-induced muscle mass, cardiac hypertrophy and improvement of the body composition. It also has a special significance to the detection of exogenous growth hormone misuse in athletes. Effects of exercise and pre-exercise feeding on the GH-IGF axis were discussed in detail.
