Effect of Intradialytic Supine Ergometer Exercise on Hemodialysis Patients with Different Nutritional Status

Abstract

It is important for hemodialysis patients to exercise while their nutritional status is being monitored. This study aimed to examine the difference in physical exercise function and the effect of exercise intervention in hemodialysis patients who were divided into two groups (high-nutrition and lownutrition groups) based on the serum albumin levels. Method: A total of 26 outpatients (18 men and 8 women) undergoing hemodialysis (age: 66 ± 10 years) were included in this study. The patients' body composition data (weight, body mass index, percentage of body fat, fat-free mass, and total body water) and physical functions (grip strength, knee extensor strength, openeyed one-legged standing time, long sitting trunk anteflexion, and 6-minute walking distance [6MWD] test) were measured. The intervention was supine ergometer exercise during hemodialysis, and the patients exercised for 30 minutes during hemodialysis thrice a week. The intervention period was three months. Results: Compared to the high-nutrition group, the low-nutrition group showed a significant decrease in muscle strength. Furthermore, long sitting trunk anteflexion in the high-nutrition group and 6MWD in the low-nutrition group improved significantly after the intervention. Conclusion:The result of this study may indicate that 6MD can be improved by exercise during dialysis, regardless of nutritional status. It is said that low nutritional status has a negative impact on survival rate; thus, considering the impact on survival rate, it is hemodialysis patients with a low nutritional status that should be considered to introduce more active exercise during dialysis.

An intradialytic aerobic exercise program ameliorates frailty and improves dialysis adequacy and quality of life among hemodialysis patients: a randomized controlled trial

“…an increase in serum albumin and pre-albumin [1]. The serum albumin concentration is a crucial dialysis-related nutritional factor that reflects protein-energy wasting, muscle strength, and physical function in connection with intradialytic exercise training [2,4,5]. However, there is insufficient evidence of intradialytic aerobic exercise combined with nutritional factors to improve body composition parameters [5].…”

Therefore, this study hypothesized that an intradialytic aerobic exercise program combined with the nutritional factor of the serum albumin concentration affects frailty, dialysis adequacy, body composition parameters, and QoL among hemodialysis patients.…”
