Effects of different carbohydrates and protein recovery mixtures on exogenous and endogenous substrate oxidation during subsequent exercise

Background A randomized, double-blind, placebo-controlled study was performed to evaluate the effect of adding protein (PRO) to a recovery mixture on exogenous and endogenous substrate oxidation during post-recovery exercise. Many studies have shown that carbohydrates (CHO) effectively restore glycogen post-exercise [1]. Some have also suggested that the addition of PRO to a CHO drink may produce further improvements [2]. CHO and PRO ingestion during recovery may result in higher CHO oxidation during subsequent exercise, which may be more beneficial to endurance performance because of preservation of endogenous substrates [3].
