"All subjects wore a three lead ECG and Polar H7 chest strap monitor and two different randomly assigned wrist worn HR monitors. These included the Apple Watch III, Fitbit Iconic, Garmin Vivosmart HR, and Tom Tom Spark 3. Once all devices were on, they were asked to run at the following speeds on a treadmill (in mph): 4, 5, 6, 7, 8, and 9 for two min. HR was assessed on all devices and agreement among measurements determined with Lin’s concordance correlation coefficient (CCC) (rc). The Polar H7 chest strap had the greatest agreement with the ECG (rc=98). This was followed by the Apple Watch III (rc=96). The Fitbit Iconic, Garmin Vivosmart HR, and Tom Tom Spark 3 all had the same level of agreement (rc=89). The Polar H7 chest strap was the most accurate, and the Apple Watch was superior among watches. For endurance athletes and their coaches, a chest strap device or Apple Watch may be the best choice for guiding workouts and performance."
