The role of intradialytic aerobic training in improved functional capacity and cognitive function in patients with chronic kidney disease on hemodialysis

Abstract

Objective: To evaluate the effect of intradialytic aerobic training on functional and cognitive function in patients with chronic kidney disease (CKD) on hemodialysis (HD). Methods: We selected eight patients on HD Facility. We conducted an exercise test (Bruce protocol) on a treadmill to exclude patients with coronary artery disease, obtain the values of maximum heart rate (MHR) and assess aerobic capacity through the maximum volume of oxygen consumption (VO2max) estimated Patients were tested for 6-minute walk (6MWT) to assess functional capacity For screening cognitive function, patients answered the instrument Mini Mental State Examination (MMSE). The ability patients were included in a protocol with intradialytic aerobic training on a cycle ergometer. The exercise was conducted during the first hour of the HD session, 30 minutes, three times a week for four months. Was used the 65-75% of maximum heart rate training range, controlled by frequency heart counter FS2 Polar. All assessments were repeated at the end of the training program. «T» test was applied and the results were presented as mean ± SD. Results: The results showed an improvement in aerobic capacity (p=0.03), accompanied by improved functional capacity (p=0.02) and cognitive function (p=0.01). (Tabel Presented) Conclusion: We found that intradialitic aerobic training has a beneficial effect on functional and cognitive function in CKD patients on HD.
