Accuracy of Commercially Available Heart Rate Monitors in Athletes

Summary

The purpose of this research is to compare four different heart rate monitors (Apple Watch Nike III,Fitbit Iconic, Garmin Vivosmart HR, Tom Tom Spark 3) to an Electrocardiograph (ECG) machine to determine the accuracy of the devices. Over the last two decades, there has been a proliferation of commercially available heart rate monitors. Elite athletes often use heart rate measurements to monitor training and fitness levels. In response, fitness companies have offered a variety of heart rate monitors to the general public. Previously, chest strap monitors that measured electrical activity were mainly used to track heart rates. More recently, wrist-worn monitors that use an optical sensor (light) to measure heart rate have gained in popularity. While the accuracy of chest strap monitors has been studied, there is currently no data concerning the accuracy of wrist-worn heart rate monitors. Assessment of the monitors' accuracy is important for subjects who rely upon the heart rate measurements to guide their athletic activity.

Interventions

DEVICE

Fitbit Iconic HR and Garmin Vivosmart HR

During testing, participants will wear two different wrist-worn heart rate monitors, the Polar H7 heart rate sensor, and will be connected to an ECG machine. Participants will be asked to perform a series of movements on a treadmill. Heart rate will be assessed under the following conditions: 1. At rest 2. 4 mph 3. 5 mph 4. 6 mph 5. 7 mph 6. 8 mph 7. 9 mph 8. Post-exercise 1 minute 9. Post exercise 2 minutes
