- Title
Ingestion of 10 grams of whey protein prior to a single bout of resistance exercise does not augment Akt/mTOR pathway signaling compared to carbohydrate.
- Abstract
The article discusses research which determines the effects of a whey protein supplement in male athletes in conjunction with an acute bout of lower body resistance on serum insulin and insulin like growth factor 1 (IGF-1) and Akt/mTOR signaling markers indicative of muscle protein synthesis. The study revealed no significant differences for IGF-1. It showed a significant main effect for serum insulin at 30 minutes post-ingestion and 15 and 120 minutes post-exercise, with no Supplement × Test interaction. It concluded that ingestion of 10 grams whey protein prior to an acute bout of lower body resistance exercise had no significant preferential effect on systemic and cellular signaling markers in untrained individuals compared to carbohydrate.
