Effect of BMI on Pedometers in Early Adolescents under Free-Living Conditions
The article reports on research which was conducted to determine whether the New Lifestyles NL-2000 (NL) and the Digi- Walker SW-200 (DW) pedometers yield similar step counts as compared with an ankle-mounted criterion, Step Watch 3, when worn by early adolescents in a free-living environment and to study whether body mass index (BMI) percentile affects the accuracy of waist-mounted pedometers in adolescents. They found that The NL and DW recorded fewer steps than the Step Watch 3 in each BMI category and that the NL is a better device for adolescents' steps than the DW, especially for those who are obese.
