Effects of Exercise and Energy Balance on 24-hour Blood Glucose Control

During the exercise session, subjects will exercise at 65% of VO2peak. One hour after the exercise session, participants will eat a standardized dinner which will NOT include the energy expended from their exercise session (- 350 kcal).

During the exercise session, subjects will use a mouthpiece and nose clip (which will allow all of their expired air to pass through the metabolic cart for analysis of oxygen consumption and carbon dioxide production) for \~5 min at the beginning, middle and toward the end of exercise to verify they are exercising at 65% of VO2peak. This will allow us to accurately measure energy expenditure (kcal) during exercise. One hour after the exercise session, participants will eat a standardized dinner which includes the energy expended from their exercise session (+ 350 kcal).
