Fat mass is negatively associated with the physiological ability of tissue to consume oxygen

Abstract Aims: To describe the relationship between variables related to body composition and peak oxygen uptake ( V ˙ O 2peak) and to verify whether fat mass can affect these relationships. Methods: Eighty participants underwent cardiopulmonary exercise testing to measure V ˙ O 2peak and a body composition assessment to measure fat mass, fat free mass (FFM), and total body mass (BM). Results: There were significant relationships between V ˙ O 2peak relative to FFM (fat free mass) (mL/kgFFM/min) and absolute fat mass (kg) (r=-0.50, p
