Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Other interventions - Structured Exercise program
Treatment: Drugs - Cholecalciferol (25-Hydroxyvitamin D)
Other interventions - Usual exercise

Active Comparator: Structured exercise program - Participants will be randomised at 3 months into either this group or the comparator of usual exercise.

Experimental: Vitamin D - Cholecalciferol 2000U per day will be given to all participants for the duration of the study

Placebo Comparator: Usual exercise - Participants randomised to this arm, at 3 months, will continue on their usual exercise routine


Other interventions: Structured Exercise program
30 minutes on an exercise bicycle during every dialysis

Treatment: Drugs: Cholecalciferol (25-Hydroxyvitamin D)
Cholecalciferol 2000U per day will be given for duration of study to all participants

Other interventions: Usual exercise
Participants randomised to this arm at 3 months will continue on their usual exercise routine for the remaining 3 months
