Description of intervention(s) / exposure
Men with Metastatic Castrate-resistant Prostate Cancer (MCRPC) who are receiving a tapered high-intensity exercise intervention plus psychosocial support will be observed for 24 months within the larger 'INTense Exercise foR surVivAL Among Men With Metastatic Castrate-Resistant Prostate Cancer (INTERVAL)' (Trial ID: NCT02730338) clinical trial. Changes in cardiovascular function will be observed and periodically tested within this 24-month period.

Participants randomised to the intervention arm within the GAP4 INTERVAL clinical trial (Trial ID: NCT02730338) will undertake 24 months of high intensity interval training. Participants will be required to complete three one-hour exercise sessions per week in either a university strength and conditioning gym or in the participant’s community/home. Each session will include a combination of high intensity aerobic and resistance exercises.

The exercise intervention will taper from fully supervised (month 1), to partially supervised (months 2-12) to fully self-managed (months 13-24). Supervised sessions will either be individual or group-based and will be supervised by an Accredited Exercise Physiologist (AEP). Participants will be provided with tailored exercise programs, designed by an AEP, for the duration of the intervention. These tailored exercise programs will be reviewed after each exercise session and will take into account each participant’s disease-status, exercise performance and exercise preferences. Programs will be delivered via a computer/phone application and thus can be accessed both at the gym and during self-managed sessions. Participants will be instructed on how to use the application during their first supervised training session.

Intervention participants will also receive psychosocial support, in the form of monthly newsletters, which will address prostate cancer-specific lifestyle factors/topics e.g. sexual health, dietary guidance.

Comparator / control treatment
Men with Metastatic Castrate-resistant Prostate Cancer (MCRPC) who are receiving psychosocial support alone will be observed for 24 months within the larger 'INTense Exercise foR surVivAL Among Men With Metastatic Castrate-Resistant Prostate Cancer (INTERVAL)' (Trial ID: NCT02730338) clinical trial. Changes in cardiovascular function will be observed and periodically tested within this 24-month period.

Men randomised to the control arm within the GAP4 INTERVAL clinical trial (Trial ID: NCT02730338) will receive 24 months of psychosocial support only. Psychosocial support will be provided in the form of monthly newsletters, which will address prostate cancer-specific lifestyle factors/topics e.g. sexual health, dietary guidance.

Participants who are screened through the GAP4 INTERVAL clinical trial (Trial ID: NCT02730338) who do not wish to consent to participate in the clinical trial (hereafter referred to as Non-GAP4/NG4) and who are still eligible for the sub-study, will be invited to form an extension of the control group for the sub-study.

Statistical methods / analysis
All participants in the sub-study will be recruited through the GAP4 INTERVAL clinical trial (Trail ID: Trial ID: NCT02730338). Approximately 60 participants randomised at a 1:1 ratio with Metastatic Castrate-Resistance Prostate Cancer will be recruited and allocated to the School of Human Movement and Nutrition Sciences, University of Queensland, St Lucia site.

Therefore, the sample size for this sub-study has been defined as a convenience sample as the sub-study will be provided with a pre-determined number of possible participants. Similar sample sizes are also commonly used in studies which investigate differences in the primary outcome for this sub-study.

All raw data will be analysed via relevant software packages. Statistical analyses of raw data will be conducted on IBM SPPS Statistics for iOS. Analysis of normal distribution, within and between group differences over the five time points will be conducted.
