Abstract
Introduction: Previous research has shown that wrist-worn devices are accurate during structured exercise such as running or walking, but accuracy decreases when it comes to high-intensity interval training (HIIT). The purpose of this study was to investigate the validity of Garmin Forerunner 645 against the gold standards of both the Polar HR chest strap and the Actigraph GT9X during HIIT. I hypothesized the Garmin Forerunner 645 would be statistically different in time spent in HR zones and calories burned when compared to the Polar HR chest strap and Actigraph.
Methods: For three weeks, I collected data by completing three 30 minute HIIT workouts in a week. During each session, I wore the Garmin Forerunner 645, Polar M400 with HR strap and Actigraph. Each device gathered data on time spent in HR zones, average HR, max HR, calories burned, and steps taken. Testing days were separated by 48 hours.
Results: Data collection is currently ongoing and results will be presented at SSD.
