    In patients in chronic hemodialysis (CH), aerobic and resistance exercises have been shown to improve fitness, metabolic and cardiovascular parameters.Objective: to evaluate in patients in CH, the impact of a resistance training routine on muscle strength, quality of life and metabolic parameters. Patients and method: thirty one patients from the dialysis unit performed a routine of dynamic and static progressive resistance training for lower body and abdomen, and low-load aerobics with a pedal board in 45 minute sessions, 3 sessions/week for 20 weeks. Weight, glycemia, lipids, 6-minute walk test and SF36 quality of life questionnaire were measured at the beginning and at the end. In seven patients, knee extensor strength was evaluated by means of the maximum voluntary contraction. The Borg scale was used to evaluate load progression.Results: nineteen patients (11M/8F), completed 47 +/- 6.4 sessions. There were no significant differences between baseline and final measurements for the evaluated parameters. The Borg scale increased significantly at weeks 10 (p< 0.05) and 20 (p< 0.01) compared to baseline, indicating that the perception of exercise intensity increased in accordance with increases in intensity in the exercise routines. In 5/8 patients, an increase over 30 meters in the 6-minute walk test was observed. Conclusion: although this exercise routine did not statistically determine significant changes in the evaluated parameters, the increase in walk capacity in some patients is relevant. More studies are needed to establish the type of exercise routine that will benefit these patients.
