Detailed Description
Study will include 86 dialysis patients. Investigators will first test the strength of lower limbs with sit-to-stand test, handgrip strength, flexibility, balance, submaximal aerobic capacity, physical characteristics and clinical parameters. After that randomization of patients in two groups will be made - one experimental and one active control group. Patients who will refuse to exercise will be invited to a non-randomized inactive control group (without exercise).
The experimental group will attend 3 times weekly a guided functional exercise before the dialysis procedure for 20 minutes and perform a cycling session during dialysis in the first phase of the study, which will last for 8 weeks. During this time experimental group will receive exercise counselling; instructions how to practice at home will be given by examples and training during functional exercise predialysis sessions.
In the second phase of the study for additional eight weeks participants will be instructed to exercise at home using the skills mastered during the first study phase on non-dialysis days, and continue with the program of intradialysis cycling. Investigators will give them advice, monitor and motivate them.
The active control group will perform intradialytic exercise (intradialysis cycling equal to cycling program of experimental group) during dialysis procedure for four months.
The primary end-point of the study is a change in the 10-repetition sit-to-stand test time as a measure of strength of lower extremities.
Exercise program will be run by a kinesiologist. Main hypothesis is that the guided functional exercise under the surveillance of a kinesiologist added to intradialysis cycling program statistically significantly improves patient's physical performance as compared to the program of intradialysis cycling alone.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Functional training and cycling
Participants in this group will perform 20 minutes of functional training before dialysis (in the first 8 weeks) and intradialysis cycling exercise during dialysis.
Participants will also receive exercise counselling; investigators will teach them how to practice at home by practice and examples given during the 20 minutes of functional training pre-dialysis.
In the second phase of additional eight weeks participants will perform the functional training at home on non-dialysis days in addition to intradialysis cycling.
Kinesiologist will monitor, advice and motivate them.
|
First 8 weeks: patients will perform 20 minutes of functional training before their dialysis procedure. The exercise program will be run by kinesiologists, who will also teach patients how to perform exercises on their own at home. During intradialysis cycling 3 times weekly participants will cycle on adapted ergometer. Participants will start with 10 - 15 minutes of cycling and then gradually increase time and intensity up to 45 minutes of duration. Second phase of 8 weeks: participants will no longer perform functional training before dialysis but will be motivated, monitored and advised to perform functional exercise at home on non-dialysis days for 20-30 minutes and continue with cycling sessions during the dialysis procedures three times weekly.

Active Comparator: Cycling
This active control comparator group will perform intradialytic cycling on an adapted ergometer 3 times per week for 4 months without functional training prior to dialysis procedure and without exercise counselling.
|
First 8 weeks: cycling on an adapted ergometer during dialysis; starting with 10 - 15 minutes of cycling and then gradually increasing time and intensity up to 45 minutes of duration. Second 8 weeks: continue with cycling at the target duration and intensity during dialysis.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change in 10 repetition sit-to-stand test time
Time Frame: baseline, 8 weeks and 16 weeks
|
Performance of the sit-to-stand test involves activation of the lower limb muscles; the test measures lower limb strength.
Participants are required to 10 times stand up from and sit down on an armless chair as quickly as possible.
Their arms should be folded across their chest.
