Summary

Arterial calcification is very common in the incident hemodialysis population, ranging 71-83%.Given that cardiovascular disease is a major cause of mortality in the hemodialysis population, medial arterial calcification may contribute through increased risk of sudden death and congestive heart failure. Applanation tonometry is the method of choice to measure pulse wave velocity and pulse wave analysis. The primary objective will be to assess the effect of a 16 week exercise program on aortic pulse wave velocity as the vascular parameter and gait speed as the physical functioning parameter. The secondary objectives will assess the effect of the exercise program on ultrafiltration rates, weight, SBP, DBP, BNP, hsTroponin, serum calcium, phosphate, albumin, glucose, LDL, HDL, TG, glycated hemoglobin, hemoglobin, CRP, micro RNAs (21, 126, 133, 146a, 221/222 and 210) and hospitalizations.

Interventions

BEHAVIORAL

Aerobic Exercise program

The 16-week program will consist of aerobic-type steady-state or interval exercises using a pedals attachable to the dialysis chairs. The purpose will be to slowly increase exercise duration by 5 minute increments to reach the goal of 30 min/treatment. The exercise program during hemodialysis sessions will contain a combination of aerobic and flexibility exercises, about 30 minutes of cycling with 10 minutes of warm up/stretching exercises and 10-15 minutes cool down. The frequency of exercise will be three sessions a week, during the first hour of dialysis treatment for the duration of 16 weeks. Blood pressure and heart continuous monitoring will be carried out during the exercise program. Exercise log sheets will be filled for each session for the 16 weeks.

OTHER

Control

No aerobic exercise is offered but baseline and end of study testing of the outcomes occur
