Introduction: Peripheral artery disease is an important part of the complications of chronic kidney disease. Measuring Ankle-Brachial Index (ABI) is the most reliable method of diagnosing this disease. According to studies, physical activity can affect the physical condition and quality of life of hemodialysis patients by affecting the function of blood vessels and the efficiency of hemodialysis. In this study, the effect of intradialytic aerobic exercise on ABI, quality of life, and dialysis adequacy was investigated.
Methods: In this study, 30 hemodialysis patients (with a mean age of 56 ± 4.02 years) were selected from dialysis treatment centers. Patients were divided into two Exercise (15 people) and Control (15 people) groups. The exercise group participated in 12 weeks of aerobic exercise (recumbent pedaling) during dialysis, but the control group underwent the usual treatment routine. Before and after the end of the exercise period, measured data were collected and statistical analysis was performed using SPSS software.
Results: Results: Results show that there was a significant difference in the mean ABI (P=0.018), dialysis adequacy (P=0.004), health-related quality of life (P=0.000), physical performance (P=0.000), relationships (P=0.000) and sleep quality (P=0.006) between the Exercise and Control groups before and after the intervention. Also, There was a significant relationship between ABI changes and quality of life (P=0.05) and between dialysis adequacy and quality of life (P=0.025), but no significant relationship was observed between ABI and dialysis adequacy (P=0/920).
Conclusion: Intradialytic Aerobic exercise has a significant effect on reducing ABI, increasing dialysis adequacy, and the patient's quality of life. Therefore, this type of exercise can be used as an important strategy to reduce heart disease and improve the quality of life of hemodialysis patients.
