Clinical Safety for the Inspiratory Muscle Training

The aim of this study is evaluate the clinical, hemodynamic and electrocardiographic responses during an inspiratory muscle training session during a single cardiopulmonary rehabilitation session program. An electrocardiogram will be continuously recorded and the heart rate (HR) and blood pressure (BP) will be evaluated before, during and immediately after a single inspiratory muscle training (IMT) session, consisting of two series of 15 cycles, with one-minute intervals between sets and an initial load of at least 30% of the initial maximal inspiratory pressure (MIP).
