Trial of Hemodialysis Based Exercise for Strength Improvement Study

Not Applicable
Conditions
End Stage Renal Disease
Interventions
Other: resistance training
Other: aerobic exercise
Registration Number
NCT01962597
Lead Sponsor
St. Joseph's Healthcare Hamilton
Brief Summary

Study Hypothesis: The combination of aerobic and resistance exercise training will improve walking speed compared to either individual intervention.

Brief Summary:

Sixty hemodialysis participants who meet inclusion and exclusion criteria will be randomized to 20 weeks of supervised exercise, using either: (i) on-dialysis aerobic exercise using a bike ergometer; (ii) pre-dialysis leg strength training using weights; or (iii) both. The primary outcome is walking speed over 4-metres. Secondary outcomes will include:

(i) short physical performance battery; (ii) health-related quality of life \[EuroQOL-5D-5L\]; (iii) Dialysis recovery time; (iv) Nottingham extended activities of daily living (EADL) index; (v) Leg strength; (vi) body composition and anthropometry.
