The purpose of this project is to assess the effects of bariatric surgery on muscle structure and function as well as investigating the feasibility of undertaking an exercise intervention post-surgery.
A single-centre feasibility research programme based at the Royal Derby Hospital centre of the University of Nottingham. This is an exploratory and feasibility study. Muscle structure and function of 12 patients will be assessed before bariatric surgery and at 6 weeks, and then 10 weeks, after surgery. After 6 weeks, participants will be randomised into two groups. Group 1 will undergo a 4 week Resistance Exercise Training (RET). Group 2 will undergo standard care procedure. The total duration of programme we are aiming for is 13-14 weeks prior to bariatric surgery and exercise intervention for 4 weeks after bariatric surgery.

|---|---|---|---|
| Group 1 Resistance Exercise Therapy Feasibility | Active Comparator | One group who have been randomised to receive 4 weeks of Resistance Exercise Therapy to explore the feasibility of introducing such a programme in the bariatric population. |

| Resistance Exercise Therapy | Other | 4 weeks of Resistance Exercise Therapy. This is a 4 week resistance exercise training programme that can be completed at home. The programme is designed to be progressive. It was designed by a bariatric physiotherapist and an exercise physiologist. This exercise programme will be discussed at the screening visit, educational material will be provided to the participants who are randomised to the intervention RET group. Safety advice will be given to each eligible participant to ensure that if they feel unwell, develop chest pain/tightness, then they must seek advice from GP/urgent care if necessary. The exercises will need to be performed at least three times a week. Compliance will be monitored with Fitbit downloads at each visit. Fitbits will be worn during exercise sessions only. |

| Measure | Description | Time Frame |
|---|---|---|
| Fasting glucose | These results will be undertaken by analysing blood samples taken by venepuncture of participants. Units will be mmol . | Total duration of study per participant is expected to be 13 to 14 weeks, there will be bloods taken on each in-person study day. Plan is for 3 of these days, screening bloods will be reviewed from the NHS interface. |
