VO_2peak and W_max before and after the training period. VO_2peak, peak oxygen uptake; W_max, maximal exercise intensity in the incremental exercise test; pre, pre-training period test; post, post-training period test; N, normoxia; H, hypoxia; IMLET, inspiratory muscle-loaded exercise training group; ET, exercise training group;* P < 0.05 vs. pre-training test. Values are mean ± SD
