Wearable heart monitor8/11/2023 It’s often challenging to compare the accuracy of wearables across multiple studies as each one may have a different design and population. The study was conducted at The Sleep Lab at CQUniversity’s Appleton Institute for Behavioural Sciences in Wayville, South Australia and participants were fitted with all six wearable devices along with ECG and polysomnography (PSG), the gold-standard of sleep tracking. CQUniversity independently examined the validity of six commonly used wearables (WHOOP 3.0, Oura Ring Generation 2, Apple Watch S6, Garmin Forerunner 245 Music, Polar Vantage V, and Somfit) for assessing sleep, heart rate, and heart rate variability during sleep. ![]() VALIDATION OF SIX WEARABLE DEVICESĪIS is a government-funded agency and global leader in high performance, supporting Australian athletes on their journey to achieve international success. This new research reviewed the day-to-day variability of HR and HRV, finding that WHOOP measurements also had a high level of reliability. The study also found that WHOOP was excellent in identifying sleep when compared to the gold-standard polysomnography (PSG) and outperformed the other devices in calculating total time asleep.ĪIS also funded a second study published in Sensors focused specifically on the reliability of WHOOP 3.0 for use in guiding training. By contrast, other wearables scored between 41% and 96% in HR accuracy and 24% and 69% in HRV accuracy. The study found that WHOOP is 99.7% accurate in measuring heart rate and 99% accurate* in measuring heart rate variability – levels of accuracy that surpassed all other wearables in the study. The Australian Institute of Sport (AIS) funded an independent, third-party study conducted by Central Queensland University (CQUniversity) which was recently published in Sensors, a leading international, peer-reviewed journal, examining the accuracy of six different wearable devices for estimating HR, HRV, and sleep. Heart rate variability (HRV) and heart rate (HR) are two metrics for which accuracy and reliability are vital as they are at the heart of all of the WHOOP scores. ![]() However, recommendations across sleep, recovery, and training are only actionable if the underlying physiological data are accurate and reliable. Wearable technology has the power to help people better understand their bodies and improve their health through personalized insights.
