Two Different Renal Rehabilitation Protocols in Hemodialysis Patients

Summary

This clinical trial will investigate how two different intradialytic exercise programs affect health in older adults with chronic kidney disease receiving regular hemodialysis. One group will perform aerobic exercise (cycling) combined with inspiratory muscle training, another group will perform resistance (strength) exercises combined with inspiratory muscle training, and a third control group will receive standard medical care without structured exercise. Men and women over 60 years of age on regular hemodialysis will be recruited from the kidney dialysis department and will exercise three times per week for three months.

Conditions

• Hemodialysis

Interventions

DEVICE

aerobic exercise

Aerobic exercise: by bicycle ergomete 5-minute warm-up before exercise and a 5-minute cool-down following exercise at intensity (40-65%HR max) were carried out each time. In addition, the exercise was performed in the first half of the dialysis session over a 3 months period for 3 sessions a week

DEVICE

resistance exercise

Dynamic closed- and open-chain resistance exercises performed by the patients' quadriceps and hamstring muscles. Patients started at 50% of their initial one-repetition maximum (1-RM) with 5 repetitions for each exercise and later progressed to three sets of 8 repetitions at 70% of their 1-RM according to the patient's Borg scale of exertion; training loads were increased when patients could comfortably complete three sets with good form.

DEVICE

inspiratory muscle training

Inspiratory muscle training at 60% of maximal inspiratory pressure for 30 minutes/session, 3 days a week, for 3 months Each patient breathes through a separate mouthpiece. The resistance is adjusted at 60% of the maximum inspiratory pressure detected from the maximum inspiratory pressure meter and is marked on the training device. A single training session consists of five sets, each containing five inspirations, with a total of twenty-five breaths with one minute of recovery between each set. The resistance was adjusted every week to be 60% of the new maximum inspiratory pressure and if it remained the same, the subject continued to train at the level of the previous week.
