Post-workout beverage provides whey protein and micronutrients.
whey protein……
— includes cysteine…….which increases glutathione
— gluthatione increased more with whey protein
— better increase in insulin compared to caseinate
— better muscle protein synthesis in whey compared to caseinate
— higher blood levels of essential amino acids in whey compared to caseinate
— higher blood levels of leucine in whey compared to caseinate
— The two main whey proteins……a-lactalbumin and ß-lactoglobulin
—– enhances neutrophil function, increases lymphocytes
– alpha-lactalbumin…..contains tripeptide [Glycine-Leucine-Phenylalanine]
—– enhances macrophage function
– alpha-lactalbumin…..high tryptophan content has neurological impact

“These data indicate that liquid carbohydrate plus essential amino acid ingestion ingestion enhances muscle anabolism following resistance training to a greater extent than either carbohydrate or essential amino acids consumed independently. The synergistic effect of liquid carbohydrate plus essential amino acid ingestion maximises the anabolic response……”
