Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The intervention will be an exercise programme incorporating both aerobic and resisted exercise for three times per week for a total of approximately 60 minutes per session (40 minutes aerobic, 20 minutes resisted) for a 6 week period. This will be in a small group session (2-3 people) supervised by a physiotherapist.

The aerobic component will be conducted on a treadmill, exercise bike or arm ergometer (depending on preference and/or disability (eg injuries to legs), at an intensity of 80 % of VO2peak established during the initial exercise test.

The resisted exercise, the three repetition maximum (3RM) (maximum weight able to be lifted a maximum of 3 times) will be established and exercise commenced at 60% of the 3RM in the first week. Resisted exercise will be progressed weekly by 5-10% by increasing the number of repetitions or the weights lifted. All resisted exercises will be carried out using variable resistance machines or free weights. Exercises included; bench press, leg press, shoulder press, triceps and biceps curl, seated row, resisted shoulder flexion / abduction, toe raises and hand / grip strengthening.

The intervention group will also receive a stretching program, holding all major joints in a stretched position for 15 seconds twice a day.

Lifestyle
Comparator / control treatment
The control group will complete only the stretching program, holding all major joints in a stretched position for 15 seconds twice a day. This will take 30 minutes per day.

The patient will be initally taught this by a physiotherapist but will then complete this exercise session at home unsupervised.

This will be measured via the metalyzer MetaMax 3B analyser (Cortex:biophysik, GMbH, Germany). Actual % REE will be compared with predicted % REE for BMI and age after an overnight fast, resting conditions and controlled ambient temperature 27 degrees celsius, based on the Respiratory quotient based equation.

Treatment
Allocation to intervention
Non-randomised trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
1. Participants living in Brisbane will be randomly allocated to one of two groups with different levels of exercise
2. Those patients not within travelling distance of Brisbane will be in the control group
3. The patient will be approached by one of the research team and asked for inormed consent
4. The person determining whether or not the patient can be included will not be aware of the randomization group as randomization will be done by a computer
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
A computer generated randomization will be used for participants residing in Brisbane

Efficacy
Statistical methods / analysis
1. A mixed method analysis will compare cortisol levels, plasma glucose, HOMA-IR, High sensitivity C- reactive protein, total cholesterol, triglycerides, high density and lipoprotein cholesterol, low density lipoprotein cholesterol, depression and PTSD scores for group*time.

2. Analysis will be by an intention to treat.

3. Correlation co-efficient between levels of cortisol and depression including change in both these parameters.
