The purpose of this study is to examine the reliability of wireless pedometers in measuring elementary school children’s physical activity. Activity measurement using a wireless pedometer Fitbit ZipTM was compared to activity measurement using Yamax Digi-WalkerTM SW701 for a group of randomly selected 25 children in Grades 3, 4, and 5. Fitbit ZipTM wireless pedometers were found to have an appropriate degree (Nunnally & Bernstein, 1994) of accuracy and reliability compared to the Yamax Digi-WalkerTM SW701 pedometer. The Fitbit ZipTM wireless pedometer collected more step counts than the Yamax Digi-WalkerTM SW701 pedometer; however, the difference was not statistically significant. Participants reported that they preferred wearing the Fitbit ZipTM to the Yamax Digi-WalkerTM SW701 because the Fitbit ZipTM was more comfortable to wear and less likely to fall off. Participants also reported being more motivated to move while wearing the Fitbit ZipTM.
