INTRODUCTION: The chronic kidney disease (CKD) is due to a renal injury and progressive and irreversible loss of kidney function. Hemodialysis replace partially this function with the objective of correcting the metabolic changes in the DRC. To monitor the adequacy of dialysis is determined the Kt/V - rate of clearance of urea per session of dialysis. The exercise of moderate intensity has been of fundamental importance for improving the adverse effects of dialysis treatment. OBJECTIVES: To evaluate Kt/V in persons with CKD submitted the isotonic exercise of low intensity during hemodialysis. MATERIALS AND METHODS: It was analyzed data from 15 volunteers with CKD, both sexes, submitted to dialysis three times a week. After two hours of the start of dialysis, was applied a protocol of isotonic exercises with low intensity of upper and lower limbs lasting 30 minutes, for a period of three months. The values of Kt/V were compared in the period of three months without exercise and after three months (monthly average). The paired Student t test was used for statistical analysis (p < 0.05). RESULTS: The average values of Kt/V within three months without exercise was 1.13 ± 0.11 and after implementation of the program of exercises was 1.29 ± 0.12 (p < 0.05). CONCLUSION: The program of isotonic exercises of low intensity in patients with CKD applied during the session of dialysis improved the efficiency dialysis.
