About this trial
This project examines whether consuming a high-protein or high-carbohydrate beverage before exercise in the heat impacts metabolism and heat balance during exercise, with the following research questions:
1. Does a high-protein vs. high-carbohydrate pre-exercise drink impact metabolism and body temperature responses during a treadmill walking in the heat? 2. Does a high-protein or high-carbohydrate drink change oxygen use and heat production during treadmill walking in the heat?
