Clevenger, Kimberly A.; Moore, Rebecca W.; Suton, Darijan; Montoye, Alexander H.K.; Trost, Stewart G.; Pfeiffer, Karin A. – Measurement in Physical Education and Exercise Science, 2018
This study examined if accelerometer-based assessments of physical activity were responsive to changes in physical activity level commensurate with performing structured versus unstructured activity in youth. Youth (6-16 years; N = 206) participated in a simulated after-school program that included structured and unstructured games on four…

Montoye, Alexander H.; Pfeiffer, Karin A.; Suton, Darijan; Trost, Stewart G. – Measurement in Physical Education and Exercise Science, 2014
The responsiveness to change of the Actical and ActiGraph accelerometers was assessed in children and adolescents. Participants (N = 208) aged 6 to 16 years completed two simulated free-living protocols, one with primarily light-to-moderate physical activity (PA) and one with mostly moderate-to-vigorous PA. Time in sedentary, light, moderate, and…
