Why the study?
Chest bands can cause discomfort from friction and pressure while running, raising the question of whether a photoplethysmography watch system could monitor heart rate with equivalent precision.
Does the Polar Vantage M PPG watch accurately monitor heart rate compared to the Polar V800-H10 chest strap in professional runners?
Does the Polar Vantage M PPG watch accurately monitor heart rate compared to the Polar V800-H10 chest strap in professional runners?
The Polar Vantage M PPG watch provides valid heart rate monitoring during running compared to chest straps, provided an initial 2-3 minute calibration period is allowed.
Polar Vantage M shows acceptable agreement after 2-min calibration in runners; extends wrist-PPG validation data but leaves broader adoption open.
Chest bands have been the most used device to monitor heart rate during running. However, some runners feel uncomfortable with the use of bands due to the friction and pressure exerted on the chest. Thus, the aim of this study was to determine if the photoplethysmography (PPG) system Polar Precision Prime used in the Polar Vantage M watch could replace chest bands (Polar V800-H10) to monitor heart rate with the same precision. A group of 37 people, middle-distance and long-distance professional runners, participated in this study. The submaximal speed was determined using 50% of the participants’ maximum speed in the height of their season. The Polar Vantage M reported high correlation ( r > 0.84) and high ICC (ICC > 0.86) when comparing its heart rate monitor with the Polar V800 synchronised with H10 chest strap during recording intervals of more than 2 min. The systematic bias and random error were very small (<1 bpm), especially for the 600 s recording interval (0.26 ± 5.10 bpm). Nevertheless, the error increased for 10 s (−5.13 ± 9.20 bpm), 20 s (−8.65 ± 12.60 bpm) and 30 s (−10.71 ± 14.99 bpm) time intervals. In conclusion, the PPG Polar Precision Prime included in the Polar Vantage M demonstrates that it could be a valid alternative to chest bands for monitoring heart rate while running, taking into account some usage considerations, good strap adjustment and an initial calibration time during the first 2–3 min.
