Specifically, respiratory muscles are also altered in patients with PH. For the treatment of PH, in addition to optimized drug therapy, studies have demonstrated the effects of physical exercise for this population. Although there is no consensus about the best exercise modality, duration, frequency or intensity, physical training promotes benefits in exercise capacity, maximal oxygen capacity (VO2peak) and quality of life. The most recent European guideline [3] recommends supervised exercise in patients with PH who are clinically stable with optimized drug therapy (evidence grade IIa, Level B), but patients often do not have access to supervised physical rehabilitation programs, which Practice a challenge.
