Overview
Brief Summary
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.
Detailed Description
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.

Outcomes
Primary Outcomes
Assessment of percentage of patients who were retained throughout the intervention arm of the study
Time Frame: Total duration of study per participant is expected to be 13 to 14 weeks
To be measured as percentage.
Assessment of percentage of patients who were compliant with the intervention arm of the study. To be guided by FitBit monitor use.
Time Frame: Total duration of study per participant is expected to be 13 to 14 weeks
This assessment will be measured as percentage of patients who met compliance targets with the intervention arm for the study.
To assess the effects of bariatric surgery on skeletal muscle ultrasound thickness.
Time Frame: Total duration of study per participant is expected to be 13 to 14 weeks
This will be assessed using muscle ultrasound and units (mm)
To assess the effects of bariatric surgery on skeletal muscle cross sectional area (cm2)
Time Frame: Total duration of study per participant is expected to be 13 to 14 weeks
This will be assessed using muscle ultrasound
Assessment of number of patients who were recruited to the study
Time Frame: Total duration of study per participant is expected to be 13 to 14 weeks
This assessment will be measured as a simple numeric value
Secondary Outcomes
- Fasting glucose(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.)
- Skeletal muscle architecture (fibre length)(Total duration of study per participant is expected to be 13 to 14 weeks, ultrasounds will be performed at each in-person study day. performed on each in-person study day)
- Muscle fatigability (maximum voluntary contractions)(Total duration of study per participant is expected to be 13 to 14 weeks, each assessment for this outcome will take place at the in-person study days.)
- Balance using the Timed Up and Go (TUG) test(Total duration of study per participant is expected to be 13 to 14 weeks, these assessments will be performed at each in-person study day.)

- Lean body mass using BIA and D3 creatine(Total duration of study per participant is expected to be 13 to 14 weeks, each participant will be provided with the resources to facilitate these assessments at their in-person study days, urine collections will be returned later..)
- Motor control in force tracking(Total duration of study per participant is expected to be 13 to 14 weeks, these assessments will be performed at each in-person study day.)
- Predicted maximum oxygen consumption (VO2 max) in step box test(Total duration of study per participant is expected to be 13 to 14 weeks, these assessments will be performed at each in-person study day.)
- Skin fold and body circumference measurements(Total duration of study per participant is expected to be 13 to 14 weeks, these assessments will be performed at each in-person study day.)
- Quality of life measurements using IPAQ questionnaire(Total duration of study per participant is expected to be 13 to 14 weeks, these assessments will be performed at each in-person study day.)
- Skeletal muscle architecture (pennation angle)(Total duration of study per participant is expected to be 13 to 14 weeks, these assessments will be performed at each in-person study day.)
- insulin resistance (HOMA-IR)(Total duration of study per participant is expected to be 13 to 14 weeks, these assessments will be performed at each in-person study day.)
- Quality of life measurements using SF-36 questionnaire(Total duration of study per participant is expected to be 13 to 14 weeks, these assessments will be performed at each in-person study day.)
