Abstract titles should be brief and reflect the content of the abstract.
Insufficient physical activity is very common among hemodialysis patients and is associated with various adverse health outcomes. What is more serious is that there is a strong correlation between the physical activity level of hemodialysis patients and the risk of death. Low physical activity levels significantly increase the risk of death, with the risk of death increasing by 62% after one year. While aerobic and resistance exercise are thought to improve health outcomes and mortality rates in these patients, high-quality randomized controlled trials to verify these effects are lacking.
To evaluate the effects of a 3-month intradialytic exercise intervention on physical activity levels and cardiovascular structure and function in hemodialysis patients.This study adopted a single-blind, randomized controlled trial at the Hemodialysis Center of the Second Affiliated Hospital of Air Force Medical University in October 2022. Sixty hemodialysis patients aged ≥18 years were recruited according to the inclusion and exclusion criteria, and randomly divided into the intervention group (aerobic and resistance exercise) and the control group (continued conventional treatment) in a 1:1 ratio. Tests were conducted at baseline and after the intervention. The primary outcome was the change in physical activity levels, including daily step counts measured by Omron pedometer (OMRON-HJ321), the Maximum Activity Score (MAS) and the Adjusted Activity Score (AAS) of the Human Activity Profile from baseline to 12 weeks. The secondary outcomes included changes in cardiovascular function and structure reflected by the left ventricular ejection fraction (LVEF), and the left ventricular mass index (LVMI). This test aims to detect the differences in physical activity levels, cardiovascular function and structure. The study was approved by the university's ethics committee (No. 2021538) and was registered on ClinicalTrials.gov and the registration number is NCT05189795.
During the 12-week intervention period, 7(11%)hemodialysis patients, 4 in the intervention group and 3 in the intervention group, were dropped out. No adverse events were reported. In the primary outcome of physical activity level, there was a significant improvement compared with the control group (P<0.05, see Table 1). The daily step count of the intervention group was observed to have a significant improvement between groups (+1570.95 steps/day). In addition, the MAS score and AAS score of the intervention group both increased (+7.02 points and +10.60 points respectively), while the control group was not affected. After 12 weeks of exercise, the MAS score and AAS score of the intervention group were significantly higher than those of the control group(P<0.05). In the intervention group, the LVEF index reflecting cardiac structure and function improved significantly (+6.50), and LVMI decreased significantly (-13.39). This was achieved within the group through exercise intervention, while the control group was not affected. Similarly, the intervention group was significantly superior to the control group in these two indicators(P<0.05).
Aerobic-resistance exercise elicited multiple beneficial effects in hemodialysis patients, evidenced by improvements in physical activity levels andcardiac structure and function.
