Fig. 2From: Effect of inspiratory muscle-loaded exercise training on peak oxygen uptake and ventilatory response during incremental exercise under normoxia and hypoxiaPercentage of change in respiratory muscle strength after the training period. PImax, maximal inspiratory pressure; PEmax, maximal expiratory pressure; white bar represents the inspiratory muscle-loaded exercise training (IMLET) group; black-bar represents the exercise training (ET) group; * P < 0.05, IMLET vs. ET. Values are mean ± SDBack to article page
