Study information
Scientific title
The effect of resistance training and aerobic exercise on vascular stiffness, novel cardiovascular risk markers, aerobic capacity, muscle strength and incidence of complications in the first year of renal transplantation. A randomised controlled study
Acronym
ExeRT Trial (EXErcise in Renal Transplant Trial)
Study hypothesis
Physical activity and exercise plays a beneficial role in maintaining the health in those with chronic illnesses however poor physical functioning among patients with chronic kidney disease is well-recognised. The use of modern immunosuppressant therapies have improved the life-expectancy of kidney grafts, however, risks of secondary complications such as diabetes, cardiovascular disease and obesity are an associated risk. It has been established that recipients of kidney transplants increase their physical activity level in the subsequent years after transplantation due to improved quality of life; however within that time they do not reach the level of physical activity of those of age matched healthy controls. Regular aerobic exercise helps to prevent and treat cardiovascular disease and to prevent and reverse arterial stiffening. Resistance training is also an important physical activity that can prevent or treat lifestyle-related diseases. However, high-intensity resistance training reduces arterial compliance and increases arterial stiffness, although this is not a universal finding. That is, regular aerobic exercise increases, whereas high-intensity resistance training decreases arterial compliance. This project will examine the effect and timing of aerobic exercise and resistance training exercise delivered in a 24-week supervised outpatient class setting, on vascular stiffness, aerobic capacity, functional ability, transplant outcomes and quality of life in patients who have received a kidney transplant. The project aims to provide evidence for the importance of exercise for patients that have received a kidney transplant and encourage the commissioning of physiotherapy services for this patient group.

Condition
Topic: Renal disorders; Subtopic: Renal disorders; Disease: All Renal disorders
Intervention
Aerobic training: AT will predominantly be on stationary exercise cycles at 80% hear rate reserve.
Resistance Training: Resistance training will use RT machines training large muscle groups (e.g. bench press, latissimus pulldown, bicep curl, triceps pull down,leg press, knee extension, hamstring curl, calf raises). Intensity will be 80% of 1RM, building up to 3 sets of 10 reps.; Study Entry : Single Randomisation only
