HIIT and Protein Study

University of North Carolina at Chapel Hill


Description

The primary purpose of this research study is to understand the effects of increasing protein (EAA) in the diet, with or without high intensity exercise (HIIT) for 8 weeks in overweight/obese individuals on body composition, muscle characteristics, and aspects of metabolism (i.e. how much and type of fuel you burn). A second purpose is to explore how these effects might differ between men and women.
