Abstract: Accurate measurement of energy expenditure, distance, and speed are desired by many runners.There are many commercially available devices for measuring these components in overground running.Purpose: The purpose of this research study was to compare the accuracy of distance, speed, and energy expenditure of overground running with two different devices: the Garmin Forerunner 405CX GPS and the Nike + iPod.Methods: Subjects consisted of 15 runners recruited from the Cleveland running community.The subjects were composed of 9 males and 6 females ranging in age from 18-55 years old.After a quarter mile calibration, the subjects ran a 3 mile measured course on an outdoor path.All devices were started simultaneously and compared.Inferential statistics (one-way ANOVA) was used to analyze the data.Results: A significant difference for energy expenditure was seen between the GPS and indirect calorimeter (p=.007) and also between the GPS and the Nike (p=.008).A significant difference in distance was seen between the Nike and the measured distance (p=.0001) and the GPS to the Nike (p=.0001).Conclusion: The GPS unit can be an accurate measuring tool for distance and the Nike can be accurate for measuring energy expenditure in overground running.
