Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
A 6 week pulse of exercise:
- The resistance training (RT) regime will consist of six exercises targeting upper and lower major muscle groups. The RT intensity will be set at 3 sets of 10 repetitions. The resistance exercises will be progressive in nature whereby if a participant can perform an additional 2 repetitions in the final set for 2 consecutive sessions, the resistance will be increased by 5%. This progressive overload approach is widely used in resistance training programming to maximize the level of adaptation.
- Participants will complete 20 minutes of aerobic exercise (AE) utilizing a variety of exercise modes and equipment. Intensity for the AE will be prescribed at 70-90% of age predicted HR max with the average HR recorded at the end of each aerobic session.
- Participants will complete 3, 60 minute gym sessions each week (consisting of the above), supervised by a senior physiotherapist in the Fiona Stanley Hospital burns gym. Participants have individualised programs. Participants may complete their programs in the gym at the same time, however there will not be formalised group training sessions.

Feasibility: Participants may choose to undertake exercises at their local gym. If they do so, they will be, required to attend FSH at least once per week to enable appropriate progression of their exercises. Where this is not possible they will need to make contact with the supervising physiotherapist via phone to support appropriate progression of their exercise program. At a minimum, participants will need to be able to attend FSH for baseline measures, at the mid-way point, three weeks, and at completion of program (6 weeks) for data collection. Exercise tracking software such as Microsoft Band will be utilised for both groups to quantify activity when not at FSH. Physitrack app will be utilised by participants to record the exercise sessions they complete, in order to monitor adherence to the exercise sessions.
- It is a cross over trial. Participants will be initially randomised into either the control or exercise group. There will be a 4 week 'wash out' period between the control and exercise condition. The control condition will be asked to continue on with their normal activity, which will be tracked with activity monitors.

Statistical methods / analysis
This is a pilot and feasibility study planned to be completed in the FWF fellowship period (1 year). Current assumptions to estimate the sample size for this study, relates to data available from burn patient chronic TNF alpha levels, which were used to inform the assumptions of the calculation. If we had enough funding a sample size of 85 patients (allowing for 15% loss to follow up) would be required to achieve 80% power to detect a change in TNF alpha, with alpha set at 5% and with an effect size of 0.3. However, this is a pilot study (aim to recruit 20 participants), where we will aim to hone the assumptions relating to the sample size to achieve definitive study outcomes and improve the strength of future grant applications to fund other components of this trial.

Summary
Brief summary
The primary aim of the study will be to longitudinally analyse the effect a 6-week pulse of exercise has on the level of inflammatory biomarkers including TNF alpha and a multiplex of other cytokines at different times frames (>1year) after burn. A cross-over trial will be conducted with participants randomised to either an exercise or control condition in the first phase. In the second phase participants will cross over into the alternate condition e.g phase 1 exercise condition participants will change over to the control condition in phase 2. Outcome measurement and blood sampling time points will be pre-intervention, at 3 weeks after commencement of intervention/control and then at 6 weeks (completion of study period 1). These will then be repeated in study period 2 at the same time points. Evidence suggests that exercise directly influences inflammation and immune function therefore we hypothesize the chronic inflammatory load after burn injury will decrease after 6 weeks of exercise.
