Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Immediate Exercise Group:
The exercise program involves resistance (e.g. lifting weights), aerobic (e.g. walking, cycling, rowing ergometer) and impact-loading (e.g. hopping, jumping) exercises undertaken 3 times per week for 6 months in an exercise clinic. Sessions will take approximately 60 minutes including the warm-up and cool-down periods. The sessions will be conducted in small groups of up to 6-10 participants under the supervision of exercise physiologists. The exercise program will be tailored to each participant. Target intensity will be 60-85% estimated maximum heart (220 – age) for aerobic exercise and 6-12 repetition maximum (i.e. a 6 repetition maximum is how much weight can be lifted 6 times) for resistance exercise.

Comparator / control treatment
Delayed Exercise Group:
Participants will remain on their usual care for the initial 6 months, then will receive the same, 6 month exercise intervention as the Immediate Exercise Group.
Control group
Active

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Central randomization by computer. Written informed consent will be required prior to any testing or randomisation. Subjects who dropout prior to completion of baseline testing will not be randomised.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation by using a randomization table created by a computer software (i.e. computerised sequence generation). Randomisation is at the level of the individual patient, and will be stratified by age and smoking status.
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?



Intervention assignment
Parallel
Other design features
The two groups of participants receive different interventions during the same time span of the study, however the delayed exercise group receive the intervention after 6 months of usual care.
