Insulin effects on strength, and exercise performance

Exogenous insulin significantly boosts the rate of glucose metabolism in training athletes along with a substantial increases in the peak V-02. Insulin is thought to enhance performance by increasing protein synthesis, reducing protein catabolism, and facilitating the transfer of certain amino acids in human skeletal muscle. Insulin-treated athletes are perceived to have lean body mass because physiological hyperinsulinemia in human skeletal muscle improves the activity of amino acid transport, which in turn promotes protein synthesis. Insulin stimulates the transport of amino acids into cells and also controls glucose metabolism. It decreases lipolysis and increases lipogenesis which is why bodybuilders and athletes use rhGH in conjunction with it as to offset this negative effect while maximizing protein synthesis. The athletes extrapolated the physiology of the diabetic patient in the sporting arena because they are interested in the suppression of proteolysis. Insulin administration is found to be protein anabolic in the insulin-resistant state of chronic renal failure. It inhibits proteolysis and when administered along with amino acids, it enhances net protein synthesis. Exogenous insulin injection creates an in-vivo hyperinsulinemic clamp, boosting muscle glycogen before and during the recovery phases of intense exercise. Power, strength, and stamina are all expected to increase as a result, and it might also speed up the healing process after intense physical activity. Second, insulin is expected to increase muscle mass by preventing the breakdown of muscle protein when consumed along with high carb-protein diet. Although a limited number of studies do suggest that insulin medication can be abused as a pharmacological treatment to boost strength and performance in young, healthy people or athletes, a recent assessment of the research argues that this is only applicable to a small group of "drug-naïve" individuals.
