Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Immediate Exercise Group:
The physical exercise intervention program will include 12 weeks of resistance (i.e. lifting weights) and aerobic exercise (e.g. walking, jogging, cycling) undertaken 3 times per week in an exercise clinic. Exercise sessions will take approximately 60 minutes and will be conducted in small groups under the supervision of an accredited exercise physiologist. Participants will also receive 3 one-on-one 45 minute consultations with a dietician during weeks 1, 2 and 3 of the intervention. These consultations will involve advice about nutritional intake for healthy fat loss, maximising gains in muscle as well as reducing whole body inflammatory state. Attendance rates and exercise training logs will be used to monitor adherence with the intervention.

Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Central randomisation by computer. Written informed consent will be required prior to any testing or randomisation. subjects who dropout prior to completing baseline testing will not be randomised
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation by a randomisation table created by a computer sequence. Randomisation is at the level of the individual patient and will be stratified by age and sex.
