Quantifying Physical Activity Time in First- through Fourth-Grade Physical Education Via Pedometry. (Grants)

Article excerpt

The purpose of this research was to determine criterion step per Minute (SPM) cut points that accurately quantify 10 min of moderate to vigorous physical activity (MVPA) within first-through fourth-grade physical education. Research objectives were to: (a) correlate physical activity measures of pedometry, triaxial accelerometry, and systematic observation; and (b) determine the validity of pedometer SPM and accelerometer vector magnitude (VM) cut points that quantify 10 min of MVPA. A total of 300 participants from the midwestern and southwestern U.S. were grouped into two data pools, first and second grade (n = 135), and third and forth grade (n = 165). Percent of and actual class time engaged in MVPA (i.e., %MVPA and MVPA time) as assessed by observation were the criterion measures (C-SOFIT, Keating et al., 1999), accelerometry VM (Stayhealthy RT3) was the comparison criterion and predictor measure, and pedometry (Yamax SW-651) SPM was the predictor measure. Data were collected from 16 first-and second-grade, and 24 third- and forth-grade lessons that averaged 31.29 [+ or -] 1.68 and 33.04 [+ or -] 6.53 min, respectively. Pearson r coefficients were computed for correlation analyses with alpha set at .01. Linear regression analyses were used to generate a set of SPM and VM cut points to be tested using the Criterion Test Model (Safrit, 1989). …
