Design outcomes
Primary
| Measure | Time frame |
|---|---|
| A composite primary endpoint of change in anaerobic threshold determined via cardiopulmonary exercise testing (CPET) (Hedges g effect size: 1.32) and whole-body muscle mass measured by dual-energy X-ray absorptiometry (DXA) (Hedges g effect size: 1.1) measured at baseline, pre-op (approx. 4 weeks after baseline) and 6 weeks post-op (approx. 10 weeks after baseline) | — |
Secondary
| Measure | Time frame |
|---|---|
| All outcome measures except those detailed otherwise will be measured at baseline, pre-op (approx. 4 weeks after baseline) and 6 weeks post-op (approx. 10 weeks after baseline): 1. Muscle protein synthesis determined via laboratory analysis of vastus lateralis muscle and saliva collection in conjunction with consumption of D2O 2. Muscle protein breakdown determined via blood sample analysis and 3-methylhistidine tracer consumption 3. Whole-body contractile mass determined via urine sample analysis and D3-creatine tracer consumption 4. VO2 peak determined via CPET 5. VL muscle architecture determined via muscle ultrasound 6. Neuromuscular function determined via electromyography 7. Mitochondrial respiration determined via Oroboros analysis of vastus lateralis biopsies 8. Anabolic cell signalling determined via Western blotting analysis of vastus lateralis biopsies 9. Clinical outcomes determined via hospital data at the end of the study (approx. 10 weeks), or earlier if information becomes available 10. Dietary intake determined by analysis of a 4-day diet diary undertaken at four timepoints: prior to the first assessment (baseline assessment), during the intervention period (week 0-4), immediately post-operation (approx. week 4-5), and 3 weeks after the operation (approx. week 7-8) 11. Functionality (including physical activity) determined via a 6-minute walk test, handgrip strength, a short performance physical battery test (measuring balance, chair-rise ability and natural gait speed), a vertical jump test (using a G-Walk [Gait and Motion Technology Ltd, Bury St Edmunds] device), exercise assessments, Duke Activity Status Questionnaire, and leg-extensions measured via dynamometery 12. Habitual activity determined using a wearable device (ActivPAL™ monitor) at four timepoints: prior to the first assessment (baseline assessment), during the intervention period (week 0-4), immediately post-operation (approx. week 4-5), and 3 weeks after the operation (approx. week 7- | — |
