Text: Inspiratory muscle training significantly increased PI (max) (59. 2 4. 9 vs 87. 5 6. 5 cmH (2) O, P =. 001) and peak oxygen uptake (14. 4 0. 7 vs 18. 9 0. 8 mLkg (-1) min (-1), P =. 002) ; decreased the peak ventilation (VE) / carbon dioxide production (VCO (2)) ratio (35. 8 0. 8 vs 32. 5 0. 4, P =. 001) and the VE/VCO (2) slope (37. 3 1. 1 vs 31. 3 1. 1, P =. 004) ; increased the HF component (49. 3 4. 1 vs 58. 4 4. 2 normalized units, P =. 004) and decreased the LF component (50. 7 4. 1 vs 41. 6 4. 2 normalized units, P =. 001) of heart rate variability ; decreased muscle sympathetic nerve activity (37. 1 3 vs 29. 5 2. 3 bursts per minute, P =. 001) ; and improved quality of life.
