The objective of this study was to examine the effects of obesity on the oxygen (O2) cost of breathing using the eucapnic voluntary hyperpnea (EVH) technique in 10 and 11-year-old children. Seventeen children (8 without and 9 with obesity) underwent EVH trials at two levels of ventilation for assessing the O2 cost of breathing (slope of oxygen uptake, V̇O2 vs. minute ventilation) and a dual energy x-ray absorptiometry scan. Resting and EVH V̇O2 was higher in children with obesity when compared with children without obesity (P=0.0096). The O2 cost of breathing did not statistically differ between children without (2.09 ± 0.46mL/L) and with obesity (2.08 ± 0.64mL/L, P=0.99), but the intercept was significantly greater in children with obesity. Chest mass explained 85% of the variance in resting V̇O2 in children with obesity. Higher resting energy requirements, attributable to increased chest mass, can increase the absolute metabolic costs of exercise and hyperpnea in children with obesity.
