Electromiography Study in the Respiratory Muscle Training in Human Lymphotropic Virus Type 1

The first training session each week will be held at the LAERF under the direct supervision of the investigator and the other two home-based training sessions under the supervisor's distance supervision. They will receive the Threshold® IMT linear loading device, and guidelines for handling, posture and asepsis. The initial training load for each participant will be adjusted to 25% of PiMáx. Participants will be trained and instructed to do the exercise program on their own at home. Once a week, during the return to the laboratory the researcher will determine the new values for load (1st week 25%, 2nd week 35%, 3rd week 40%, 4th week 45%, 5th week 50%).
