Abstract
【Purpose】The aim of this study was to clarify the effects of resistance training (RT) during hemodialysis (HD) therapy on physical function and nutritional status in patients receiving HD with malnutrition. 【Methods】We studied 75 ambulant HD patients (47 male, 28 female, age 63±13 years old). They were divided into 2 groups according to the Geriatric Nutrition Risk Index (GNRI) at the beginning of RT : 19 patients in the MN group (GNRI<91) and 56 patients in the C group (GNRI≧91). We assessed Short Physical Performance Battery (SPPB) and performed Life Space Assessment (LSA) as indicators of physical function, as well as measuring serum albumin (Alb) and GNRI as indicators of nutritional status at the beginning and after 9-month RT during HD therapy. 【Results】SPPB score, LSA score, Alb and GNRI at the beginning of RT in the MN group were significantly lower than those in the C group (p<0.05). However, SPPB score, LSA score, Alb and GNRI after 9-month RT in the MN group were significantly improved (p<0.05), at which time SPPB score and LSA score no longer differed significantly between the MN group and the C group. 【Conclusion】RT during HD therapy is feasible for improving physical function and nutritional status in hemodialysis patients with malnutrition.
