The effects of an exercise training in hemodialysis patients

The purpose of this study was to investigate the effect of exercise training on work capacity, psychologic functions and quality of life in hemodialysis patients. Forteen hemodialysis patients, 3 males, 11 females, age ranged from $23{\sim}58$ years($42.3{\pm}0.4$) were selected and assessed using a modified Bruce protocol on a treadmill. The 3 months supervised exercise training consisted of 60 minites session thrice weekly on the treadmill, bicycle and arm ergometer at $40{\sim}60%$ of maximum $O_2$ consumption. The changes of maximum $O_2$ consumption, psychologic test and quality of life questionnaire in 14 patients before and after 3 months exercise training have been measured. The mean maximum $O_2$ consumption($VO_2$ max) of exercises increased by 23% after training(pre-and postexercise $26.3{\pm}4.6ml$/kg/min vs $29.8{\pm}4.9ml$/kg/min, p=0.013). There was significant reduction in anxiety score(p=0.004) and significant improvement in quality of life score(p=0.031) after training. The result of this study indicated that a structured exercise training for hemodialysis patients provides many benefits. These result suggest the exercise training can improve the work capacity, psychologic functions and quality of life outcomes in hemodialysis patients.
