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.

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.

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.

Summary
Brief summary
This study aims to determine if immediate exercise therapy can improve health by reducing initial adverse effects during the initial phase of AST and if this provides superior benefits to delayed exercise therapy.

Who is it for?
You may be eligible to join this study if you are a man with prostate cancer who is about to initiate AST.

Trial details.
Participants in this trial will be randomly (by chance) allocated to one of two groups. One group will immediately undergo supervised exercise training 3 times per week for 6 months. This involves aerobic (walking/jogging, cycling, rowing), resistance (lifting weights), and impact (hopping, jumping) exercises and then monitored (without training) for a further 6months. The other group will be assigned to usual care for the first 6 months. After this time participants in this group will commence the exercise program for the next 6 months.

Participants will have measurements of bone mineral density, body composition, blood markers, blood pressure, arterial stiffness taken at 4 occasions (baseline, 3-, 6-, and 12-months). Participants will also complete tests of their muscle strength, balance and physical function as well as complete a series of questionnaires at these time points.
