The main function of the respiratory muscles is the movement of the thoracic wall, thus exerting ventilation, and the increase in the work of this muscle is directly proportional to the intensity of the activity performed De Troyer et al. [1-3]. During basal respiration, the slow-twitch fibers are used, while the fast-twitch fibers are recruited because of increased heart rate Sinderby et al. [4]. The diaphragm moves caudal approximately 1 to 3cm. Under conditions of ventilatory effort this incursion can reach up to 10cm. For an adequate work performed by the ventilatory muscles, approximately 1 to 3% of the oxygen consumption (VO2) Kress et al. [5,6].
