Postpartum Exercise and Return to Fitness: Optimise Readiness for Military Mums (PERFORM) (PERFORM)
The Efficacy of a Post-Partum Physical Development Programme on Occupational Physical Performance and Musculoskeletal Health

Intervention / Treatment
Detailed Description
In an independent groups study design, the aim was to investigate the efficacy of a postpartum physical development programme on core reconnection (i.e., pelvic floor function, core strength/stability and urogynaecological measures), occupational physical performance, musculoskeletal health, and psychological health/wellbeing in servicewomen. Given that policy guidance is urgently needed regarding the safe return of servicewomen to functional occupational fitness, the aim of our proposed research is to inform the appropriate physical preparation of servicewomen in the postpartum period.
Participants at selected sites around the Royal Military Academy at Sandhurst will receive usual care/no formal intervention (acting as a control group [CON]) and participants at different sites around Army Headquarters will receive usual care and additionally complete an 18-week phased physical development (rehabilitation and training) programme between weeks 6 and 24 postpartum (acting as the intervention group [INT]). If recruitment numbers are low at the main sites (Aldershot and Tidworth) we will seek to recruit participants to INT from Bulford, Middle Wallop, Larkhill and Marlborough Lines for INT and to CON from Sandhurst, Odiham, Pirbright, Keogh, Minley, Deepcut as well as locations outside of the named INT sites. The geographical separation of sites was deemed to be important for maintaining differences between intervention and control group activity.
The investigators have designed a phased 18-week physical development programme to train both rehabilitative and performance enhancement elements of physical preparation. The rehabilitation element of the programme will specifically target pelvic floor function and core strength and stability (known collectively as Core Reconnection training) from weeks 6 to 24 postpartum, and the training element of the programme will contain resistance and high-intensity interval training (HIIT) from weeks 12 to 24 postpartum
The aim of this research is to investigate the effectiveness of a tailored rehabilitation and physical preparation programme for postpartum women on:
- Occupational fitness performance;
- Female health assessments (i.e., urinary incontinence, pelvic floor strength);
- Musculoskeletal health;
- Psychological health and wellbeing.

The World Health Organisation Quality of Life Questionnaire (WHOQOL-BREF) will be given to participants in paper.
The WHOQOL-BREF provides an overall quality of life/wellbeing score and allows calculation of a score for each of the four sub-scales (physical health, psychological, social relationships and environment).
The four domain scores are scaled in a positive direction (higher score equal higher quality of life).
The mean score of items within each domain is used to calculate the domain score.

Time Frame: The Edinburgh Post Natal Depression Scale will be measured at weeks 6, 12 and 24 postpartum.
|
The Edinburgh Post Natal Depression Scale (EPDS) asks participants to answer questions by reflecting on the past 7 days.
The questionnaire produces a total score of postnatal depression symptoms (range 0-30) with a score of 13 and above indicating likelihood of a depressive illness of varying severity
|
The Edinburgh Post Natal Depression Scale will be measured at weeks 6, 12 and 24 postpartum.
|

|
Body composition will be measured at weeks 6 and 24 postpartum.
|
Bone Health Changes Between 6 and 24 Weeks Postpartum
Time Frame: Bone health will be measured at weeks 6 and 24 postpartum.
|
Bone microarchitecture will be determined at weeks 6 and 24 by a HRpQCT scan; two scans of the tibia (distal 4% and 30% site) will be performed on the non-dominant leg to assess training-induced changes in bone microarchitecture and density.
|
Bone health will be measured at weeks 6 and 24 postpartum.
|
Tendon Properties Changes Between 6, 12 and 24 Weeks Postpartum
Time Frame: Tendon properties will be measured at weeks 6, 12 and 24 postpartum.
|
Tendon stiffness and young's modulus will be measured using ultrasonography with a linear array probe.
Patella tendon length and elongation will be calculated as the distance from the apex of the patellar and the shadow created by a fixed marker.
Patella tendon stiffness will be calculated by dividing knee extensor torque by the estimated patella tendon moment arm.
Knee extensor torque will be calculated as the sum of the measured knee extension torque and the antagonistic torque, estimated through the root mean square of the biceps femoris muscle electromyography signal.
Force-elongation data will be fitted with to a second order polynomial curve to determine patella tendon stiffness.
Tendon CSA will be assessed along the full resting length of the tendon on the axial plane through ultrasonography.
Young's modulus will then be calculated as tendon stiffness multiplied by the ratio of tendon length over tendon cross-sectional area.
|
Tendon properties will be measured at weeks 6, 12 and 24 postpartum.
|
Muscle Architecture Changes Between 6, 12 and 24 Weeks Postpartum
Time Frame: Muscle architecture will be measured at weeks 6, 12 and 24 postpartum.
|
Fascicle length of the vastus lateralis will be assessed at weeks 6, 12 and 24 by the acquisition and analysis of images taken using B-mode ultrasonography (MyLab Omega, Esaote, UK), with a linear array probe.
Images will be obtained with the participant lying at rest in a supine position.
Images will be taken at 50% of the length of the vastus lateralis and at the midsagittal line of the muscle.
The transducer will be aligned to the fascicle plane to allow optimal capture of the fascicles.
|
Muscle architecture will be measured at weeks 6, 12 and 24 postpartum.
|
Muscle Protein and Collagen Turnover Changes Between 12 and 18 Weeks Postpartum
Time Frame: : Muscle protein and collagen turnover will be measured at weeks 12 and 18 postpartum.
|
Muscle protein/collagen turnover will be measured from blood, saliva and skeletal muscle biopsy samples.
Participants will provide a saliva sample before being given a drink of 'heavy' water (D2O); water that is enriched with a metabolic isotope tracer that can be used to evaluate the rate of protein and collagen turnover by determining the rate of tracer incorporation into muscle tissue.
The muscle biopsy will be used to measure the incorporation of deuterated alanine into muscle tissue over time and enable the calculation of the fractional rate of muscle protein synthesis by mass spectrometry.
|
: Muscle protein and collagen turnover will be measured at weeks 12 and 18 postpartum.
|
Muscle Mass Changes Between 6, 12, 18 and 24 Weeks Postpartum

We intend to estimate whole-body muscle mass using D3-Creatine (D3-Cr), measured in urine at weeks 6, 12, 18 and 24 postpartum.
Using a creatine-tracer measure of muscle mass, Urine D3-creatine and D3-creatinine and unlabelled creatine and creatinine will be measured by liquid chromatography/mass spectrometry, which will allow the calculation of total body creatine pool size and muscle mass.
|
Muscle mass will be measured at weeks 6, 12,18 and 24 postpartum.
|
Muscle Breakdown Changes Between 12 and 18 Weeks Postpartum
Time Frame: Muscle breakdown will be measured at weeks 12 and 18 postpartum
|
We intend to estimate muscle breakdown using D3-3-methylhistidine (D3-3MH), measured in urine at weeks 12 and 18 postpartum.
Isotopic enrichment of D3-3MH in urine will be measured by gas chromatography/mass spectrometry, which will allow the calculation of muscle protein breakdown.
|
Muscle breakdown will be measured at weeks 12 and 18 postpartum
