Brief Summary
The purpose of this study is to assess whether the greater performance benefits from ingesting carbohydrate-protein supplements during endurance running, in comparison to the traditionally used carbohydrate supplement, is attributed to the extra calories contained in the carbohydrate-protein supplement or the presence of protein.
