The FACIAL Study Pilot

"Healthy participants will be situated on a cycle ergometer fitted with a 12-lead ECG or chest-strap heart rate monitor. Data from the questionnaire will be stored in a study site file in a locked cabinet in an office. Baseline readings will be obtained whilst on the bike for 3 minutes before the subject embarks on a 3-minute warm-up at 50 Watts (W). The workload (watts) on the bike is then increased to a workload that corresponds to a heart rate of 120 bpm (gentle exercise). The workload will then be increased by 25-50W every three minutes until volitional exhaustion. Between each stage, there will be a 30s rest period where the participant will be cycling with minimal resistance (freewheeling) but will be otherwise stationary on the cycle ergometer. Still images of the face and facial video recordings will be taken during a 30s rest period between increases in exercise intensity. A finger-prick blood sample (glucose \& lactate) will be taken at the beginning and every 3 minutes."
