Relative Sarcopenia and Cardiometabolic Risk in Young Adults With Obesity

CPET studies will be performed in the Cardiovascular Performance Program exercise lab at MGH. Subjects will undergo CPET on an upright cycle ergometer with continual measurement of metabolic gas exchange via a commercially available metabolic cart as well as heart rate and blood pressure. Exercise will proceed according to a maximal effort clinical protocol. Subjects will then undergo a standardized 30-min work load on the upright cycle ergometer based on the results of the maximal effort clinical protocol.
