Document Summary

Lecture 22 - nutritional interventions to attenuate muscle wasting. Specific amino acids (leucine, glycine, and citrulline) Protein/aa intake to enhance adaptations to diet and exercise interventions. Rda vs. recommended amount of protein intake. Glycogen is one of the determinants of exercise performance: high carbohydrate feeding. To optimize body substrate stores before exercise/competition. To enhance substrate availability during exercise and spare muscle glycogen stores and optimize performance. To increase the rate of glycogen synthesis in the recovery phase. To increase muscle protein synthesis and muscle repair and reduce muscle damage. Betahmb well known supplement derivative of leucine. Suggested you take in atp -> has beneficial affect on muscle. Solid = received supplements of betahmb + atp 12 weeks of high intensity resistance training: gained 14% of their lean mass. How likely is this true: compared to injecting anabolic steroids, like testosterone, and claiming that it has a greater affect is highly unlikely.
