Effects of Intra-dialytic, Short-term Resistance Exercise on Physical Fitness, Depression and Dialysis Adequacy

Abstract

This study aims to identify effects of intra-dialytic, short-term strength exercises on physical fitness, depression anddialysis adequacy. In addition, we aim to examine the minimum level of momentum that positive effect is displayedfor each part. The subjects were 27 hemodialysis patients who have no disability in free living. They were allocatedto a moderate amount exercise group and a low amount exercise group. Both groups joined strength exerciseprogram during hemodialysis which was set three times a week for 4 weeks. The exercise program was progressedby warm up, main exercise, and cool down that was designed to use low limb and core muscles. Measurementswere taken before and after the intervention. In physical factor, body composition, physical fitness, physical function,physical activity level and, dialysis adequacy was measured. In psychological part, depression was measured. Asa results, body composition, physical function, physical activity and dialysis adequacy were not changed by exerciseintervention. However, leg strength and agility was increased (p＜0.05) after 4-week moderate amount exerciseprogram. Also, depression was significantly improved (p＜0.05) in both exercise group.
