Influence of carbohydrate-protein beverage on cycling endurance and indices of muscle disruption.

Unlabelled: Carbohydrate-protein (CHO+Pro) beverages reportedly improve endurance and indices of muscle disruption, but it is unclear whether these effects are related to total energy intake or specific effects of protein.

Purpose: The authors examined effects of CHO+Pro on time to exhaustion and markers of muscle disruption compared with placebo (PLA) and carbohydrate beverages matched for carbohydrate (CHO) and total calories (CHO+CHO).

Methods: Eleven male cyclists completed 4 rides to exhaustion at 75% VO2peak.
