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