Assessment centre ⏵ Physical measures ⏵ ECG during exercise
DescriptionThis category contains data on cardio-respiratory fitness, and involves heart-rate monitoring (using a 4-lead electrocardiograph [ECG]; CAM-USB 6.5, Cardiosoft v6.51) during cycle ergometry on a stationary bike (eBike, Firmware v1.7) with a ramp slope that is adapted to the individual based on age, gender, weight and medical history. ECGs were recorded pre-test (15 seconds), during activity (6 minutes) and in recovery (1 minute). The participant's risk category was first calculated to determine what level of activity they should perform or have only a resting ECG performed. The percentage levels of effort during activity were then determined according to their risk category, and their maximum workload was calculated according to age, height, weight, resting heart rate and sex. These measures were introduced to the Assessment Centre towards the end of recruitment.
