Functional status and dyspnea as performance of activities of daily living after physical and inspiratory muscle training in patients with chronic obstructive pulmonary disease


IBICT - Instituto Brasileiro de Informação em Ciência e Tecnologia




Background: Exercise training improves exercise capacity, the performance of activities of daily living, decreases dyspnea, and enhances the inspiratory muscle strength in patients with COPD. Less is known on ventilatory and metabolic responses ( E, O2) during the execution activities of daily life (ADL) in patients going through physical training with additional or non-additional inspiratory muscle training (IMT). Aim: This study aims to compare changes on E and O2 responses, dyspnea, oxygen saturation and ADL time during a standard set of ADL tasks after two different training programs. Methods: A set of 5 ADL using a metabolic system (making bed, taking shower, brushing teeth and combing hair, lifting and lowering containers on a shelf above eye level and below the pelvic waist) was performed by 28 patients with COPD before and after the whole protocol. Patients were divided into two groups. One performed aerobic training, lower limbs (LL) resistive exercise and respiratory exercise (GPT) and the other aerobic training, resistive exercise of LL and an additional IMT (GPT+IMT). 13 composing the GPT (age 67.17.3yrs, FEV1 43.04.0%pred) and 15 patients composing the GPT+IMT (age 67.411.7yrs, FEV1 51.03.0%pred). Results: Both groups had a significant reduction (p<0.05) of E, O2 and Borg and a significant improvement of SpO2 during the ADL set within them showing benefits of physical training on performance of ADL. However, adding IMT did not show additional benefits in those variables between groups. There was a significant difference (p<0.05) in PImax in both groups and between them. On the other hand, although there are no differences between groups, both of them improved their performance in the cardiopulmonary test and six minute walking distance. Conclusion: The pulmonary rehabilitation reduces metabolic cost of common tasks of daily life as both groups improved their performance in the ADL set and, even with IMT, additional benefits were not perceived.
