The Impact Of Stand-Biased Desks On After-School Physical Activity Behaviors In Children, Nathan Tokarek
The Impact Of Stand-Biased Desks On After-School Physical Activity Behaviors In Children, Nathan Tokarek
Theses and Dissertations
The purpose of this study was to assess changes in after-school time spent performing sedentary behavior (SB), light intensity physical activity (LPA), and moderate to vigorous-intensity physical activity (MVPA) among elementary school children in response to the introduction of stand-biased desks in the classroom. Thirty-one 6th grade participants randomly assigned by their teacher to a traditional (CON) or stand-biased (INT) desk provided complete accelerometer data. After-school PA and SB were measured on four consecutive weekdays at baseline and 10-weeks. Wilcoxon Rank Sum Tests were used to detect significant differences (p<0.10) in changes in the proportion of after-school wear time performing SB and PA between groups. Results suggested no significant differences in changes in after-school time performing SB (p=0.770), LPA (p=0.740), or MVPA (p=0.470). Significant differences in the change in moderate PA (INT: -1.4%; CON: -0.2%, p=0.093) were detected. Stand-biased desks were not detrimental to children’s after-school PA and SB.

Examining Fifth-Grade In-School Physical Activity Patterns And How Many Days Of Monitoring Are Needed, Tyler R. Langosch
Theses and Dissertations
PURPOSE: The purpose of the study was to examine in-school physical activity patterns among fifth-grade students residing in a Midwestern community. Variables observed were minutes of vigorous + activity, vigorous activity, moderate activity, easy activity and very easy activity along with steps and calories expended. A secondary purpose of this study was to determine the minimum number of days necessary to estimate mean physical activity levels, as both moderate-to-vigorous physical activity (MVPA) and steps per day, in fifth-grade students using objective physical activity monitors across two semesters. METHODS: Activity patterns were assessed during two school semesters, spring (N = 82 …
