Abstract

Five throwers from the Australian Institute of Sport volunteered to participate in this study. These athletes undertook a weight training circuit after being assigned to a pre-determined diet and amino acid supplement program. Each athlete took part in six programs (one per week), each program varying with regard to diet, amino acid and placebo intake. The purpose of this study was to investigate the effect of the interaction of diet, amino acid supplements and exercise on the release of growth hormone (GH). Of the six programs used, exercising in the fasted state resulted in a sevenfold increase in GH release over a program where food was eaten before exercising. The addition of amino acid supplements did not significantly enhance the release of GH under specified dietary conditions. Training in the fasted state would appear to optimise the release of GH.
