ClinicalTrials.gov Identifier:	NCT00604929

Purpose

The present proposal is designed to examine the effect of carbohydrate and protein co-ingestion on muscle protein synthesis during endurance type exercise activities. We hypothesize that muscle protein synthesis is higher when protein is co-ingested during exercise.

Condition	Intervention
Healthy	Dietary Supplement: carbohydrate and protein

Study Type:	Interventional
Study Design:	Basic Science, Randomized, Double Blind (Subject, Investigator), Placebo Control, Crossover Assignment
Official Title:	The Effect of Carbohydrate and Protein Intake on Muscle Protein Synthesis During Endurance Exercise
