A feasibility study of interval training in people with chronic kidney disease

Background: Patients receiving haemodialysis often become lethargic, fatigued, and sedentary, performing minimal exercise; resulting in reduced physical fitness. Haemodialysis tends to impact on patients sleeping habits, quality of life, biochemical blood markers and nutritional status. Aims: This study was conducted as a joint venture between Armidale Rural Referral Hospital (ARRH) and the University of New England to assess the feasibility and possible benefits of interval exercise training in haemodialysis patients, as a pilot for a larger trial. There is no previous research on the effects of interval exercise training in people with CKD receiving haemodialysis. Methods: The participants were five haemodialysis patients at ARRH who had been receiving dialysis for at least two months, aged between 18 and 75 years. Patients were assessed using six minute walktest (6MWT), Epworth Sleepiness Scale, Kidney Disease Quality of Life Short Form questionnaire and routine blood tests. The participants underwent a two month observation period followed by two months interval exercise training whilst on haemodialysis. The study participants acted as their own controls. Results: An interval exercise program was provided to the haemodialysis patients. Improvement trends were seen in the 6MWT distance, exercise performance, daytime sleepiness and quality of life. Implications for clinical practice: This study demonstrated the positive interaction between allied health departments to improve and promote the health of haemodialysis patients. There is feasibility for future collaboration between university and the health district to address service and skills gaps.
