Increasing Physical Activity in Schools: Strategies for School Health Practitioners.

Background. Colorado passed House Bill 11-1069 in 2011 requiring all public elementary schools to provide students with a minimum of 30 minutes of physical activity (PA) per school day (Physical Activity Expectation in Schools, 2011). The purpose of this article is to describe the results of a 3-year initiative to increase opportunities for PA and to provide recommendations for school health practitioners implementing similar programming. Intervention. In 2014, 13 school districts were funded to increase student PA during school hours and before and after school hours. Intervention activities spanned all components of the Comprehensive School Physical Activity Program framework. An evaluation was conducted to estimate the number of schools providing at least 30 minutes of PA a day. A mixed methods evaluation design was implemented that included tracking the number of minutes of PA provided before, during, and after school and semistructured interviews with school health coordinators. Results. In Year 1, an average of 48 minutes of PA were provided per day. By the end of year 3, the average minutes of PA doubled to 90 minutes per day. Teachers and staff identified professional development and administrator support as key components to incorporating more PA throughout the school day. Conclusions. Health promotion interventions in schools can increase access to PA opportunities for students. Sustainability of PA efforts in schools is dependent on funding to support professional development for teachers and staff and building administrative support for school-based PA.

A Profile of Active Transportation in Colorado Public Schools, 2014-2015.

Active transportation (AT) may represent an ideal opportunity to accumulate physical activity (PA). Thus, the purpose of this study was to describe the AT profile among students from two Colorado school districts. Students completed a survey on AT resulting in a final dataset (n = 3738) from which descriptive and inferential statics were calculated. Respondents were 11.32 ± 2.82 years of age (Boys = 48.27 %; Girls = 51.73 %). Most students (87.29 %) traveled to or from school via automobile, while 11.17 % walked and 1.53 % biked. Boys rode bicycles to school significantly more (p < 0.0001) than girls, and when walking, accumulated significantly more time (p = 0.02) than females. When examining by grade level significant differences were found for days/week walking (p = 0.0002) to school and biking (p < 0.001) to school. High school students accumulated significantly (p < 0.0001) more time walking to school than middle or elementary school students. Similarly, high school students spent more time biking (p < 0.0001) to school than middle school and elementary school respondents. These findings indicate that travel to school by automobile is still the dominant mode of travel for most public school students. Further, males were generally more likely to obtain extra time in AT. Moreover, older students were more likely to engage in AT, and to spend more time during their AT.

An Evaluation of an Unstructured and Structured Approach to Increasing Recess Physical Activity.

BACKGROUND: The purpose of this study was to evaluate an unstructured and a structured program designed to increase physical activity (PA). The unstructured program increased the amount of equipment during recess, whereas the structured program introduced activities to students. METHODS: PA was observed using the System for Observing Play and Leisure Activity in Youth (SOPLAY) in two school districts in Colorado. Researchers recorded baseline and follow-up observations for sedentary activity, moderate PA, and vigorous PA, as well as for available equipment for the unstructured program. Observations from schools were aggregated for data analyses at the district level. RESULTS: For the program increasing equipment, moderate PA and vigorous PA increased, while sedentary behavior decreased. For the structured program, moderate PA and vigorous PA did not increase, whereas sedentary behaviors increased following the program. CONCLUSIONS: Other variables are likely influencing student PA during recess, such as teachers' interaction with students or the fidelity of the program. Results indicate that funding and implementing a program aimed at increasing PA will not necessarily accomplish that goal, and additional research should be performed to determine the best practice for increasing PA.

Intensity of commonly-reported classroom-based physical activity opportunities in public schools.

The purpose of this study was to examine the intensity levels of PA opportunities offered in public school classrooms. Schools (N = 101) in school districts (N = 25) reported PA opportunities offered in classrooms using an online data collection tool over a two-year period (2014-2016). Using a randomized sampling technique, 20-30% of teachers in each school were selected each week to report PA in their classroom. These responses resulted in N = 18,210 usable responses. A researcher determined the intensity of PA opportunities using the 2011 Compendium of Physical Activities as a guideline; two additional researchers confirmed the coded categories. A descriptive analysis of PA opportunities was conducted to describe the proportion of opportunities whose intensity levels were light (LPA), moderate (MPA), vigorous (VPA), sedentary (SED), and those of unknown intensity. Chi-square analyses were utilized to examine differences between proportions of intensity levels offered by semester. Kruskal-Wallace tests were utilized to examine differences in proportion of physical activity opportunity intensity offered by grade level. Most PA opportunities were MPA (58.7%), followed by VPA (17.6%) and LPA (11.5%). Few responses were SED (0.5%), and 11.6% were of indeterminate intensity. A greater proportion of more physically intense activities reported during the fall versus spring semesters (p < 0.0001). Differences in the intensity levels of PA offered by grade also differed, with a trend of decreasing intensity as grade level increased (p < 0.0001). This study provides insight into the PA actually occurring in classrooms; a previously underexplored construct of school-based PA.
