Effect Of Actigraph's Low Frequency Extension For Estimating Steps And Physical Activity Intensity, Yuri Feito, Lyndsey M. Hornbuckle, Lauren A. Reid, Scott E. Crouter

Faculty Articles

This study examined the effects of the ActiGraph’s (AG) low-frequency extension (LFE) filter on steps and physical activity classification in the free-living environment. Thirty-four African-American women (age, 24.5±5.2 years; BMI, 24.9±4.5 kg/m2) had daily activity measured simultaneously with an AG-GT3X+ accelerometer and a New Lifestyles NL-800 pedometer for seven days. Steps per day (steps/day) and time (minutes/day) spent in sedentary, light, and moderate-to-vigorous physical activity (MVPA) were examined with and without the LFE filter (AG-LFE and AG-N, respectively). The AG-LFE recorded more total steps (13,723±4,983 steps/day) compared to AG-N and NL-800 (6,172±2,838 and 5,817±3,037 steps/day, respectively; p<0.001). Compared to the AG-N, the AG-LFE estimated less time in sedentary behaviors (518.7±92.1 vs. 504.2±105.4 min/day, respectively; p<0.001), and more time in light (247.7±70.4 vs. 279.1±74.7 min/day, respectively; p<0.001) and MVPA (18.9±16.9 vs. 21.5±18.2 min/day, respectively; p<0.001), respectively. These data suggest that steps and physical activity classifications will be affected when using the ActiGraph with and without the LFE filter. Future research should investigate the accuracy of these measures using the LFE filter.

Stretched Too Thin?: The Relationship Between Insufficient Resource Allocation And Physical Education Instructional Time And Assessment Practices, Lindsey Turner, Tyler G. Johnson, Hannah G. Calvert, Frank J. Chaloupka

Kinesiology Faculty Publications and Presentations

With provisions in the Every Student Succeeds Act, attention to physical education (PE) programs in school will be crucial for developing well-rounded students. We assessed the availability of resources that have the potential to impact PE (staffing, continuing education, annual PE equipment budgets) in a nationally-representative sample of 640 U.S. public elementary schools. Higher student-to-PE teacher ratios were associated with students not receiving adequate instruction. Equipment budgets were minimal (median = $500) and 30% of schools had no budget at all. Additional financial support from federal and state education agencies would help schools to better meet recommendations for PE.
