Brief Summary:
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 or disease Intervention/treatment Phase
Healthy Dietary Supplement: carbohydrate and protein Not Applicable

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 12 participants
Allocation: Randomized
Intervention Model: Crossover Assignment
Masking: Double (Participant, Investigator)
Primary Purpose: Basic Science
Official Title: The Effect of Carbohydrate and Protein Intake on Muscle Protein Synthesis During Endurance Exercise
Study Start Date : August 2008
Actual Primary Completion Date : February 2009
Actual Study Completion Date : February 2009

Arm Intervention/treatment
Experimental: 1 Dietary Supplement: carbohydrate and protein
The intake of carbohydrate and protein during endurance type exercise



Primary Outcome Measures :
  1. Differences in muscle protein synthesis rates between carbohydrate and carbohydrate + protein. [ Time Frame: 1 day ]

Secondary Outcome Measures :
  1. Difference in whole-body protein synthesis and breakdown between carbohydrate and carbohydrate plus protein. [ Time Frame: 1 day ]
