Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The intervention that will be investigated in this project is exercise. Participants in group 1 will have a choice to participate in an exercise intervention (EX) or standard care (CON). Participants in the EX group will perform exercise three times per week for eight weeks. Each exercise session will run for 30 minutes and be performed at a moderate intensity (55-70% heart rate (HR) maximum, 40-59% HR reserve). Participants maximum HR will be measured in baseline testing. All participants will perform exercise at the same RELATIVE intensity. Exercise will be continuous aerobic exercise performed on a stationary recumbent cycle ergometer. All exercise session will be supervised face-to-face by an accredited exercise physiologist. All sessions will be delivered individually. All sessions will be performed at the University of South Australia Clinical Trials Facility. Participant adherence to exercise sessions will be determined by number of sessions attended/number of available sessions (24), using a session attendance checklist. Participant HR will be recorded at the 5, 10 15, 20, 25 and 30 minute mark of each exercise session, to determine adherence to the exercise intensity protocol. Participants in group 2 will undergo the same exercise program, however following a randomised crossover design. Participants in group 2 will be randomised to either an exercise or non-exercise arm first, and then swap into the other group at the completion of the first arm (either exercise and non-exercise). A minimum of 4-weeks wash out will occur before swapping into the other arm, with no maximum wash out period. Testing, outcome measures and exercise procedures will remain exactly the same as per above for group 1.

Comparator / control treatment
Participants in the CON group will undergo standard care treatment. No change to standard care treatment will be made. Standard care includes access to an exercise intervention at the Royal Adelaide Hospital during chemotherapy treatment. No restrictions will be placed on participants regarding the amount of exercise they can perform during the period between baseline and end of intervention testing. Self-reported physical activity will be measured using the International Physical Activity Questionnaire - Short Form, to account for exercise contamination. The exercise intervention included in standard care treatment at the Royal Adelaide Hospital is an individualised exercise intervention involving both aerobic and resistance based exercise, and is offered to participants 3x per week. Attendance to these exercise session is optional. The exercise intervention that will be performed by the EX group is described above, and will consist of continuous aerobic based exercise at moderate intensity, that is relative to the participants baseline exercise testing results.

Prevention
Allocation to intervention
Non-randomised trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Group allocation will be performed by a member of the research team who has no involvement in the screening, enrolment, and baseline testing phases. Therefore, the member of the research team who enrols participants will not be aware of which group the participants will be randomised too.

Efficacy
Statistical methods / analysis
Group 1 will follow a non-randomised, pre-post design, and be presented as a series of case studies. As such, no sample size calculations are relevant for this group. Group 2 following a randomised crossover design. The mean and standard deviation of GLS from each arm of the first three completed participants was used to retrospectively calculate sample size, using a matched-pair t-test. With a standard deviation of the difference in means between groups of 1.53, nine participants were required to provide 80% power to detect a mean difference of 1.7 between groups (10% relative change in GLS from a baseline GLS of -17%), with an alpha of 0.05.
As data will be presented case by case for group 1, no grouped analysis will be performed. All variables will be tabulated and presented as raw values. Relative change from baseline will be calculated for echocardiography and cardiorespiratory fitness variables and presented as a percentage (%). For group 2, continuous variables will be expressed as mean?±?standard deviation. A linear mixed effect model will be used to compare outcomes between (exercise vs control) and within (pre- vs. post-intervention) groups for echocardiographic and cardiorespiratory fitness variables. For all analyses, participant id will be considered as a random effect. All participants who complete at least one arm of the trial will be included in the analysis. Pearson’s (r) correlation will be performed to determine the association between relative change in GLS and VO2peak. All data will be analysed using Stata statistical software (v17.1, Stata Corp, TX, USA).
