Effect of Intradialytic cycling exercise on 2 minutes walking test and VO2max in chronic kidney disease patients

Abstract

Patients with end stage CKD are characterized by low levels of physical activity and ongoing decline in physical function, especially with routine hemodialysis (HD). Physical inactivity significantly increases the risk of morbidity and mortality in patients with HD. Two Minute Walking Test (2MWT) and VO2 max are parameters that can be used to evaluate functional capacity and cardiopulmonary fitness. Exercise can improve cardiovascular ability, dialysis effectiveness, physical function, and health-related quality of life in patients undergoing HD. This study aimed to investigate the effect of intradialytic cycling exercise on the 2MWT and VO2max in CKD patients undergoing hemodialysis Thirty CKD patients participated in this study. From the total, 4 subjects dropped out, leaving twenty-six CKD patients. Subjects divided into exercise and control groups were able to follow the study until the end. The exercise group did a low-intensity intradialytic cycling exercise program for 12 weeks. Both groups were given education about physical function and cardiopulmonary fitness in CKD patients and continued drug therapy and diet as before. 2MWT and VO2max were evaluated before and after the intervention.
