Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The participants will undertake a test of their physical function and exercise (mobilisation). Although the exercise is considered usual physiotherapy care after cardiac surgery, completing the test of physical function is not part of usual care.
The test of physical function will be the short physical performance battery and will include a measure of walking speed, lower limb strength assessment during a sit-to-stand activity and a measure of balance.
The exercise undertaken will be walking performed on the ward, the distance and intensity determined by the physiotherapist. The exercise prescription and completion of the short physical performance battery will be administered by the participant's treating physiotherapist.
The exercise and test of physical activity will take approximately 20 minutes maximum to complete and will be undertaken at Day 3 post cardiac surgery, on the ward.
During the exercise and test of physical function, cardiorespiratory parameters (heart rate, respiratory rate and oxygen saturation) will be measured and the levels of perceived exertion and dyspnoea will be recorded.

Timepoint [1] 374102 0
Day 3 post cardiac surgery
Secondary outcome [2] 374877 0
Results of the Short Physical Performance Battery test. This will be measured by the participants' treating physiotherapist and will include measures of walking speed over 4 metres, standing balance and lower limb strength tested by repetitive sit-to-stand activities
Timepoint [2] 374877 0
Day 3 post cardiac surgery
Secondary outcome [3] 375144 0

Statistical methods / analysis
Data will be described using mean±SD or median±interquartile range depending on the data distribution. Relationship between cardiorespiratory parameters and exercise intensity and cardiorespiratory parameters and the SPPB total score will be analysed by Spearman’s rho or Pearson’s correlation coefficient, with alpha set at 0.05
