Are Heart Rate Monitor Watches Accurate?
Compared to chest strap monitors (including some of these best Bluetooth heart rate monitors), wrist-based heart rate monitors aren't quite as accurate. Dr. Marc Gillinov, Chairman of the Department of Thoracic and Cardiovascular Surgery at the Cleveland Clinic, explains that wrist-worn heart monitors tend to vary in terms of accuracy.
That's because unlike chest heart rate monitors, which detect and measure the electronic signal that your heart transmits every time it beats, wrist-based monitors rely on optical sensors to measure the blood as it flows through your veins. These readings are less accurate in part because your heart rate is measured when blood is flowing farther from your heart.
Which Watch Has the Most Accurate Heart Rate Monitor?
Ben Pulham, head coach and founder of Coached, explains that placement of your wrist-based monitor is crucial for getting accurate readings. After all, if the monitor is positioned incorrectly or is too loose, it may move around as you exercise, and will ultimately lose its accuracy. Instead, a properly placed wrist-based monitor should feel a bit uncomfortable, as it needs to be securely in place to accurately monitor your heart rate.
If you're looking for the best heart rate monitor watch that doesn't involve wearing a chest strap, we've found a few that stand out from the rest. The Polar Ignite, Garmin Instinct GPS watch and the Suunto 9 all stand out for their athlete-oriented capabilities. Polar's Ignite combines bio-impedance electrodes and optical sensors for more accurate heart rate monitoring, while the Garmin Instinct GPS watch uses dependable optical heart rate technology to provide crucial feedback.
What Is the Best Smartwatch for Heart Monitoring?
The top heart rate monitoring watches look different for everyone. If your focus is more on the performance aspect of the watch, consider a fitness watch that expertly calculates the metrics you need to track your performance. For example, runners and cyclists may look for exercise watches with GPS technology to track distance, cadence and routes.
If your workouts are more water-oriented, you can choose between multiple heart rate monitoring watches for tracking swim workouts. If you're looking for a strapless heart rate monitor, most of these watches stand out for their convenient wrist-based heart rate monitoring.
