简要总结
The aim of the study is to determine the effect of functional exercise and training counseling by kinesiotherapist in addition to the basic exercise program of cycling during dialysis on physical performance of dialysis patients.
详细描述
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.

研究组 & 干预措施
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.
干预措施: Functional training and cycling (Other)
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.

结局指标
主要结局
Change in 10 repetition sit-to-stand test time
时间窗: 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.
次要结局
- Change in 6-minute walk test distance(baseline, 8 weeks and 16 weeks)
- Change in serum interleukin-6 (IL-6)(baseline, 8 weeks and 16 weeks)
- Change in lean and fat body mass(baseline, 8 weeks and 16 weeks)
- Change in Stork balance test time(baseline, 8 weeks, 16 weeks)
- Change in sit-and-reach test distance(baseline, 8 weeks, 16 weeks)
