Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Progressive Resistance Training (PRT).
The PRT intervention will include 8 machine-based/free-weight exercises involving the upper and lower body and the trunk. The intervention will be prescribed with a warm-up set followed by 3 sets of 8 repetitions at 80% of their current capacity.

Participants will train 3 days per week, for 12 weeks. Each session will last approximately 45-60 minutes. Participants will exercise in a University based gymnasium, Participants will be fully supervised throughout the whole intervention period.

Exercises will include leg press, knee extension, knee flexion, chest press, seated row, triceps, hip abduction, and plantar flexion initially. Total session time will be approximately 45 min, with a ratio of no more than 1 trainer for 4 participants. Participants will be progressed continuously throughout the intervention, guided by one repetition maximum (1RM) strength testing every 2 weeks to maintain intensity at least 80% of current maximum capacity.

Participants in this group will also remain under the usual care of their GP for the management of their depression and metabolic syndrome

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Randomisation will occur by contacting the holder of the allocation schedule who is at central administration site and not otherwise involved with the study
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
We will use a concealed, computer-generated sequence (www.randomization.com) of randomly permuted variable blocks, stratified by sex, age (40-59; 60+) and current treatment for depression (yes/no). Randomisation will occur at the completion of the baseline assessment.

Efficacy
Statistical methods / analysis
An intention-to-treat analytic strategy will be utilised, inclusive of all participants randomised, regardless of dropout. All outcomes will be analysed using linear mixed effects models with repeated measures. Main effects of PRT, TIME and PRTxTIME will be entered, and models adjusted for covariates selected a priori (age, sex, treatment for major depressive disorder) as well as additional confounders associated with the dependent variable of interest. Significance will be set at a=0.05 for primary and pre-specified secondary outcomes, with unspecified outcomes undergoing Bonferroni adjustment.
