Arms Assigned Interventions
Active Comparator: Structured exercise program
Participants will be randomised at 3 months into either this group or the comparator of usual exercise.
Other: Structured Exercise program
30 minutes on an exercise bicycle during every dialysis
Experimental: Vitamin D
Cholecalciferol 2000U per day will be given to all participants for the duration of the study
Drug: Cholecalciferol (25-Hydroxyvitamin D)
Cholecalciferol 2000U per day will be given for duration of study to all participants
Placebo Comparator: Usual exercise
Participants randomised to this arm, at 3 months, will continue on their usual exercise routine
Other: Usual exercise
Participants randomised to this arm at 3 months will continue on their usual exercise routine for the remaining 3 months
