Assessments were made on the first working day after hemodialysis, following notification and consent of the medical teams. Patients initially underwent anthropometric measurements and vital signs, later carried out the assessment of peripheral muscle strength, pulmonary function test, submaximal exercise capacity and quality of life questionnaire and depression. After these procedures, the patients were randomized to select HG or LG by opaque envelopes. These evaluations were performed at baseline and after 12 sessions of completion of the protocol.
