Further study details as provided by University of Manitoba:

Primary Outcome Measures:
  • Aerobic exercise capacity as measured by VO2 peak [ Time Frame: 3 and 6 months ]
  • physical function as measured by sit to stand to sit; sit and reach and 6 minute walk test [ Time Frame: 3 and 6 months ]

Secondary Outcome Measures:
  • quality of life measured by SF36 [ Time Frame: 3 and 6 months ]
  • dialysis adequacy as measured by ktV [ Time Frame: 3 and 6 months ]

Enrollment: 60
Study Start Date: July 2007

Arms Assigned Interventions
Active Comparator: A
Ergometer during hemodialysis
Behavioral: ergometer exercise during hemodialysis
Active Comparator: B
Pedometer use outside of hemodialysis
Behavioral: pedometer activity outside of hemodialysis

Detailed Description:

Study Design:

Prospective, randomized, controlled trial of chronic hemodialysis outpatients within the Manitoba Renal Program.

Potential patients include any individual receiving chronic outpatient hemodialysis in Winnipeg (Seven Oaks, Sherbrook, Central and St. Boniface dialysis units) and the Brandon hemodialysis unit.

Exercise Interventions:

Patients will be block randomized to one of the following 2 interventions:

Group A: Cycling on an ergometer GOAL 60 minutes 3 times per week on hemodialysis for 24 weeks A cycling ergometer will be placed on the floor in front of the patient's dialysis chair or at the foot of the bed (if there are only beds available in that unit). The patient will be allowed to exercise anytime during the first half of each dialysis treatment. Goal frequency will be 3 times per week during their usual scheduled hemodialysis treatments.

Group B: Pedometers This group will each receive a pedometer (StepsCount®) at the onset of the study following exercise testing. They will be educated regarding the technical use of the pedometer and will receive the handout entitled "Pedometer Information Sheet: Get Physically Active One Step at a Time!" They will also receive verbal education regarding use of the pedometer and goal activity levels from the exercise study supervisor.


Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • All adult (>18 years old) patients
  • Treated with hemodialysis for > 3 months
  • Hemoglobin > 100 g/L over the previous 2 months
  • Kt/V > 1.2 for last month and no history of shortened dialysis due to hemodialysis access issues or frequent alarming during dialysis due to poor access will be eligible for the study.
