Figure 1 Individual responses to insulin of the pulmonary gas exchange and exercise capacities. Filled circles are the means ± SD. *p < 0.01 vs. baseline. DL_CO = lung diffusing capacity for carbon monoxide; D_M = diffusing capacity of the alveolar-capillary membrane; peak VO₂ = oxygen consumption at peak exercise; V_c = pulmonary capillary volume available for gas exchange; VE/VCO₂ slope = slope of the increase in ventilation with respect to carbon dioxide production; VO₂AT = oxygen consumption at the anaerobic threshold.
