Effect of Intradialytic Resistance Versus Aerobic Exercise on Cardiovascular System in Patients on Regular Hemodialysis

Обзор

The purpose of the study is to compare the effect of resistance exercise and aerobic exercise on intradialytic hypotension in patients undergoing hemodialysis.

Подробное описание

Chronic kidney disease (CKD) is one of the leading causes of global morbidity and mortality. In the 2019 Global Burden of Disease study, CKD was among the top ten risks associated with the highest number of deaths worldwide, with a death toll of 3.16 million deaths.

Patients undergoing dialysis in Egypt in 2020 are mostly men (59%), and half of them are aged ≥55 years. Hypertension is the most common cause of end-stage kidney disease at 41%, followed by diabetes at 14%, whereas glomerulonephritis is the primary diagnosis in 3% of patients undergoing dialysis.

Hemodialysis (HD), continuous ambulatory peritoneal dialysis, and kidney transplantation are the three main modalities of renal replacement therapy. Hypotension is the most reported complication of routine outpatient HD treatments.

Toxic substances, also called uremic toxins, in the blood result in malaise, paraesthesia, mental impairment, peripheral circulatory disturbance, and muscle dysfunction.

While patients exercise during dialysis, those toxins move through the dialyzer with a large flux from the tissue to the vascular compartment. It results in increased muscle blood flow and opened capillary surface area. Besides, the intradialytic exercise showed not only better adoption and adherence but also a lower drop-out and greater compliance.

So, this study will investigate the effect of resistance and aerobic exercises on intradialytic hypotension in patients undergoing hemodialysis. thus, may affect the quality of life in chronic kidney disease dialysis patients. The results of this study may shed light on which of the selected exercises can decrease the risk of Intradialytic hypotension to help dialysis patients. To our knowledge, there are no previous similar studies.

  Patients with chronic kidney disease will receive an intradialytic aerobic exercise for 12 weeks (3 sessions/ week). Duration: 30 minutes during the first 2 hours of each dialysis session using a stationary bicycle ergometer in a supine position or seated position. Time of session: The warming up and the cooling down phase consists of 5:10 minutes of slow Pedaling. the main exercise phase consisted of 20 minutes of cycling. Intensity: The use of the Borg's Scale of Perceived Exertion (RPE) sc
