Objective: Investigate differences in ActiGraph GT9X vertical axis counts and step counts with monitors clipped onto the waistband at the hip compared to the three methods of attachment at the traditional waist placement. Methods: Three laboratory-based treadmill test conditions were utilized: (1) 3 mph in blue jeans, (2) 3 mph in athletic shorts, and (3) 6 mph in athletic shorts. Three monitors were attached in different methods to the traditional elastic belt (2 threaded options and 1 clipped), and one accelerometer was clipped onto waistband at the hip. Results: No differences were observed between attachment methods for step counts in any test condition (P > 0.05). When considering physical activity intensity classification accuracy, all attachment methods (100% of the time) generated counts within the same intensity category. Conclusion: Clipping the accelerometer to the waistband produces comparable data to that of the elastic belt (within any threading configuration) and may reduce participant burden.
