Activity trackers, pedometers and other technological devices have recently become a popular way for individuals to monitor the amount of physical activity performed daily. Many studies have recently been conducted to determine the validity of various pedometers when used in different stages of physical activity. The purpose of this study is to test the accuracy of the Omron HJ-323u activity tracker by determining whether this particular model of activity tracker can accurately count how many steps someone takes while moving at different speeds. Furthermore this study will determine if there is a relationship between a participant’s body mass and the accuracy of steps recorded, as well as determine if there is a relationship between steps recorded and placement of the activity tracker. 30 college students’ steps were recorded as they walked on a treadmill at speeds of 1.0, 3.0, and 5.0 mph with activity trackers attached at both wrists, both hips, and the chest. Participants also walked twice around a 200m loop while researchers recorded their steps. It was hypothesized that activity trackers placed on the dominant side of the body would record more valid results at all speeds than trackers on the non-dominant side or the chest. Significant results would validate the Omron HJ-323u activity tracker as well as allow the tracker to be used to confidently during exercise to measure performance. This study is ongoing, and results will be available during the poster celebration.
