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. K.; Pivarnik, James M.; Mudd, Lanay M.; Biswas, Subir; Pfeiffer, Karin A. – Measurement in Physical Education and Exercise Science, 2016
The purpose of this article is to compare accuracy of activity type prediction models for accelerometers worn on the hip, wrists, and thigh. Forty-four adults performed sedentary, ambulatory, lifestyle, and exercise activities (14 total, 10 categories) for 3-10 minutes each in a 90-minute semi-structured laboratory protocol. Artificial neural…

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…
