The studies that have been performed on respira­tory muscle endurance are based on the capacity of the respiratory muscles to sustain and generate high levels of pressure. The most common test consists of generating a pressure against a given resistive inspi­ratory load. In our study, we used the Nickerson, Keens and Kelsen methods, that consist [...]

It can be seen in Table 1 that there is evidence that the patients suffered a moderate obstruction of air flow and the volumes are increased. Three of the patients had a Deo of less than 80 percent due to clinical and radiologic signs of pulmonary emphy­sema. The average TLIM of the sample was 3.7 [...]

Sample The study was conducted on eight male patients with COPD in stable phase, that is, the patients had not shown any symptoms of acute relapse in a period of at least two months prior to the study. The average age was 60.57 ±7.59 years, the height was 162.14 ±10.43 cm, and the weight was [...]

To or some years now, resistive inhalational loads have been used to evaluate the endurance capacity of the inspiratory musculature under exertion. The capacity to sustain the muscular exertion required to inhale depends on the force and duration of the inhalational muscle contraction, which is determined by the pressure-time ratio. It is known that healthy [...]
