Values are means ± SE. ERV, expiratory reserve volume; FEF_25-75, forced expiratory flow from 25 to 75% of forced vital capacity (FVC); FEV₁, forced expiratory flow in 1 s; HDL, high-density cholesterol; IC, inspiratory capacity; LDL, low-density cholesterol; RBC, red blood cells; $\text{S}{\text{p}}_{{\text{O}}_2}$, oxygen saturation; SVC, slow vital capacity; WBC, white blood cells. N = 8.
