Trial Review

Please note the ANZCTR will be unattended from Friday 20 December 2024 for the holidays. The Registry will re-open on Tuesday 7 January 2025. Submissions and updates will not be processed during that time.

Description of intervention(s) / exposure
The aim of this study is to determine the impact of a progressive Accredited Exercise Physiologists (AEP) led resistance and aerobic training program on time to dialysis efficiency in haemodialysis patients as well as assess the impact of the intervention on nutritional status, body composition, physical function and quality of life.

Participants will perform a progressive exercise program at the satellite haemodialysis unit (pre dialysis and intra-dialysis exercises) for 17 weeks (i.e. 3 days / week for 17 weeks or until at least 180 minutes of physical activity per week has been achieved). The exercise will be led (in person) by an Accredited Exercise Physiologist with support from exercise physiology students. The pre dialysis exercise will be small group exercise sessions facilitated in person by an exercise physiologist. Tailored pre dialysis resistance training exercises will be prescribed for each patient to last 30 minutes including warm up and cool down. The program will target the major upper and lower body muscle groups, intensity will be progressively increased to ensure program progression and promote physiological adaptation. Intensity will be manipulated from the participant’s predicted Repetition Maximum (RM) or 60-75% of predicted RM, using 1-2 sets per exercise.

The intra-dialysis aerobic exercise sessions will include warm up, aerobic conditioning and cool down components using cycling on an arm/leg ergometer, as well as integrating basic body movements while seated to promote continuous aerobic exercise for a minimum of 30 minutes. The aerobic component of the intervention will commence within 1½ hours of starting HD treatment at an intensity of 55-70% of Heart Rate Maximum (HRmax), preferably above 60% HRmax, or a rating of 11-13 using the Borg Rating of Perceived exertion (RPE) scale.

Participants will work towards achieving 180 minutes of exercise / week.

The pre dialysis exercise will be small group exercise session led by an exercise physiologist. The on dialysis exercise will be individualised to each patients own capacity and facilitated in person by the exercise physiologist.

Patients will follow procedures, activities, and/or processes in accordance with their perceived capacity as directed by the exercise physiologist.

Comparator / control treatment
Prospective cohort study (pre / post study design). The outcome measures will be collected from participants before and after completion of the exercise program so that changes can be quantified.

Outcomes
Primary outcome [1] 301881 0
time on dialysis to achieve dialysis adequacy with the intervention. Dialysis adequacy will be assessed by pre and post dialysis change in urea. Urea is a middle molecular weight molecule that readily crosses the dialysis membrane and the clearance of this molecule from the blood during dialysis is the standard measure of dialysis efficacy.

Dialysis adequacy will be assessed by the single pool model of urea kinetics (spKt/V) and the urea reduction ratio (URR). the equation used to estimate urea clearance in this research project is the Jindal single pool model of urea kinetics (spKt/V). The spKt/V will be taken from the dialysis machine and the URR will be calculated by collecting pre and post dialysis urea pre intervention and once / month during the 4 month intervention taken on the say day as the routine monthly dialysis blood test.

The primary outcome will measure the effect of exercise on dialysis adequacy assessed by change in SpKt/V and URR.
Timepoint [1] 301881 0
The exercise intervention will run for 17 weeks. the primary outcome will be assessed at time zero and then monthly across the 17 week intervention (e.g. 5 times in total).
Secondary outcome [1] 334182 0
change in nutrition adequacy assessed by a 2 day food recall including one dialysis day and one non dialysis day, Food Frequency Questionnaire (FFQ) (Australian Eating Survey), and Patient Generated Subjective Global Assessment (PG-SGA).
Timepoint [1] 334182 0
time zero and at completion of the intervention (at 17 weeks)
Secondary outcome [2] 335816 0
change in body composition assessed using Dual-energy X-ray absorptiometry (DEXA);
Timepoint [2] 335816 0
time zero and at completion of the intervention (at 17 weeks)
Secondary outcome [3] 335817 0
change in physical function assessed by the short physical performance battery, box and block test, 6 minute walk test and 2 minute step test
Timepoint [3] 335817 0
time zero and at completion of the intervention (at 17 weeks)
Secondary outcome [4] 335818 0

Timepoint [4] 335818 0
