Why the study?
Data on the validity of wearable photoplethysmography heart rate measurements are limited and often restricted to one exercise domain or limited intensities.
Do the Polar OH1 and Fitbit Charge 3 wearable devices accurately measure heart rate compared to a criterion chest strap in healthy adults during various exercise intensities?

Limited validity data across activities leaves open wearable PPG reliability for clinical use; broader validation trials needed.
Do the Polar OH1 and Fitbit Charge 3 wearable devices accurately measure heart rate compared to a criterion chest strap in healthy adults during various exercise intensities?
The Polar OH1 provides valid heart rate measurements across various exercise intensities, whereas the Fitbit Charge 3 is generally inaccurate, especially during cycling and high-intensity sprint exercises.
Muggeridge et al. (2021) studied this question.
