Accuracy of Heart-Rate-Recovery Parameters Assessed From a Wrist-Worn Photoplethysmography Monitor (Polar Unite).
Int J Sports Physiol Perform

Purpose: The accuracy of heart rate (HR) measured with a wrist-worn photoplethysmography (PPG) monitor is altered during rest-exercise and exercise-rest transitions, which questions the validity of postexercise HR-recovery (HRR) parameters estimated from this device.
Methods: Thirty participants (50% female) randomly performed two 13-minute sequences (3' rest, 5' submaximal-intensity exercise, and 5' passive recovery) on treadmill and bicycle ergometers. HR was measured concomitantly with a 10-lead electrocardiogram (ECG) and a wrist-worn PPG monitor (Polar Unite).
Article Synopsis
- The accuracy of heart rate readings from wrist photoplethysmography monitors can be influenced by the tightness of the wristband, arm movements, and the type of physical activity (steady-state vs. transitioning).
- Thirty participants performed exercises on a treadmill and bicycle while heart rates were measured using different devices, including a 10-lead ECG and wrist monitors set at varying tightness levels.
- Results indicated that tighter wristbands and different exercise phases significantly improve the correlation and reduce measurement errors between wrist monitors and the ECG, highlighting the importance of proper wristband fitting for accurate heart rate monitoring.
