Assessing Heart Rate Using Consumer Technology Association Standards

It is difficult for developers, researchers, and consumers to compare results among emerging wearable technology without using a uniform set of standards. This study evaluated the accuracy commercially available heart rate (HR) monitors Consumer Technology Association (CTA) Participants (N = 23) simultaneously wore Polar chest strap (criterion measure), Jabra Elite earbuds, Scosche Rhythm 24 armband, Apple Watch 4, Garmin Forerunner 735 XT during sitting, activities daily living, walking, jogging, running, cycling, totaling 57 min monitored activity. The mean bias was within ±1 bpm, absolute percent error (MAPE) <3% in all six conditions. underestimated HR conditions, except cycling MAPE >10% sedentary, lifestyle, walk-jog, running. ±5 bpm each condition, exceeded 10% walk-jog. <5% In conclusion, only Series 4 displayed acceptable agreement across By employing CTA standards, future will be able make true comparisons devices.
