History of Changes
  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: Allocation: Randomized
Intervention Model: Crossover Assignment
Masking: Double Blind (Subject, Investigator)
Primary Purpose: Basic Science
Official Title: The Effect of Carbohydrate and Protein Intake on Muscle Protein Synthesis During Endurance Exercise

Further study details as provided by Maastricht University Medical Center:

Primary Outcome Measures:
  • Differences in muscle protein synthesis rates between carbohydrate and carbohydrate + protein. [ Time Frame: 1 day ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Difference in whole-body protein synthesis and breakdown between carbohydrate and carbohydrate plus protein. [ Time Frame: 1 day ] [ Designated as safety issue: No ]
