Pfeiffer, Karin A.; Lisee, Caroline; Westgate, Bradford S.; Kalfsbeek, Cheyenne; Kuenze, Christopher; Bell, David; Cadmus-Bertram, Lisa; Montoye, Alexander H.K. – Measurement in Physical Education and Exercise Science, 2023
A universal approach to characterizing sport-related physical activity (PA) types in sport settings does not yet exist. Young adults (n = 30), 19-33 years, engaged in a 15-min activity session, performing warm-ups, 3-on-3 soccer, and 3-on-3 basketball. Videos were recorded and manually coded as criterion PA types (walking, running, jumping, rapid…

Martin, Eric M.; True, Larissa; Pfeiffer, Karin A.; Siegel, Shannon R.; Branta, Crystal F.; Wisner, Dave; Haubenstricker, John; Seefeldt, Vern – Measurement in Physical Education and Exercise Science, 2021
Research tracking sport participation from youth to adulthood is relatively rare, as is research that tracks youth sport participation with regard to adult physical activity (PA) levels, especially in the United States. Aims of this study were: 1) To investigate the degree to which sport participation tracked across youth, adolescence, and early…

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…

Pfeiffer, Karin A.; True, Larissa; Martin, Eric; Siegel, Shannon R.; Branta, Crystal F.; Haubenstricker, John; Seefeldt, Vern – Measurement in Physical Education and Exercise Science, 2021
The Michigan State University Motor Performance Study (MPS) was initiated in 1967 and lasted 32 years. Three central components existed: 1) Educational component, in which students experienced applied work with youth; 2) Instructional component, whereby enrolled youth received sport-specific skill instruction; and 3) Research component. The…

Evaluating the Responsiveness of Accelerometry to Detect Change in Physical Activity
Peer reviewed Peer reviewed
Direct linkDirect link
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…
