  • Values are means ± SD; n, no. of subjects exceptn = 21 for all subjects and 2 for low-intensity group residual volume (RV). FEV1, forced expiratory volume in 1 s; FVC, forced vital capacity; TLC, total lung capacity. Significant difference (P ≤ 0.05):

  • F4-150 from T1;

  • F4-151 T2 vs. T3;

  • T1 vs. T3 and T2 vs. T3.
