- Abstract
This study aimed to evaluate by surface electromyography the behavior of inspiratory muscles in the muscle training of volunteers with human T-cell lymphotropic virus type 1. This was a clinical trial. Seven volunteers, 58,85 ± 7.21 years old, underwent inspiratory muscle training at home for 4 weeks, 3 times a week, 30 minutes daily by means of a linear load stimulator. The maximum inspiratory pressure data and the surface electromyography data were used for evaluation in the pre (T0), second week (T2) and after the fourth week (T4) training phases. There was a progressive increase in inspiratory muscle strength from T0 to T4 (p = 0.007), as well as an increase in the recruitment of motor units by analyzing the amplitude of the electromyographic signal, being more evident for the sternocleidomastoid muscle (p = 0.12) in comparison to the diaphragm muscle (p = 0.6). During the muscle training inspiratory muscle strength improves with greater recruitment of muscle fibers from the muscles analyzed in the sample.
