Background:

The primary purpose of this study was to describe the association between activity time and step counts in children.

Methods:

Subjects were 590 students (334 girls, 256 boys) with each gender having a mean age of 9.2 ± 1.8 y. All subjects wore the Walk4Life 2505 pedometer for four consecutive weekdays. This pedometer simultaneously measures both step counts and activity time.

Results:

Boys accumulated significantly more minutes of activity time/day (140.9 ± 39.6 vs. 126.3 ± 38.1), steps/day (13,348 ± 4131 vs. 11,702 ± 3923), and steps per min (93.99 ± 5.8 vs. 91.85 ± 5.8) than girls (P < 0.001) Steps/day was a significant predictor of activity time/day (P < 0.0001).

Conclusions:

Boys accumulate more steps per day and more activity time per day than girls. There is a strong association between steps per day and activity time in children. Daily steps per minute as a measure of free living physical activity in children is explored

Background:

National and state organizations have called upon afterschool programs (3–6 PM, ASP) to promote physical activity (PA). Few strategies exist that ASPs can use to increase the PA of children enrolled. This study evaluated a policy-level intervention (Movin’ Afterschool, MAS) designed to increase PA through staff implemented policy-level changes and ongoing technical support.

Methods:

Twelve preexisting community-based ASPs serving 580 children (5–12 yrs, 57% girls) were invited to take part in MAS. Evaluation of children’s PA, staff behaviors (engaged or promote PA, other ASP tasks, general supervising), and environmental features (equipment, organized PA) at baseline (Fall 2010) and postassessment (Spring 2011) were collected using SOPLAY (System for Observing Play and Leisure Activity in Youth) for boys and girls, separately. Random effects models evaluated changes in PA categories (sedentary, walking, vigorous).

Results:

The percentage of boys and girls sedentary decreased by 11.8% and 11.4%, respectively. Girls walking increased by 6.9% while boys vigorous PA increased by 6.5%. Greater increases in vigorous activity were observed as postassessment in organized activities for boys and during indoor activities for girls.

Conclusions:

Findings indicate a policy-level approach targeting staff training and ongoing technical support can produce notable increases in PA within the ASP setting.

Background:

With the rapid increase in obesity rates among youth, efforts to increase physical activity (PA) have become a priority. School-based strategies for PA promotion must be cost-effective, unobtrusive, and linked to improved academic performance. Efforts to maximize recess PA are advocated because of both health and academic benefits. The purpose of this manuscript was to review recess interventions aimed to improve PA among youth, and make recommendations to develop related best practices.

Methods:

An extensive literature search was conducted to include all primary research articles evaluating any recess intervention with PA as an outcome.

Results:

The included 13 interventions represented both settings within the U.S and internationally, among preschools and elementary/primary schools. A variety of strategies were used within the design and implementation of each of the interventions including: added equipment/materials, markings, zones, teacher involvement, active video games, activity of the week, and activity cards. Of the included studies, 95% demonstrated positive outcomes as a result of the recess intervention.

Conclusions:

A number of simple, low-cost strategies can be implemented to maximize the amount of recess time students are allotted. Long-term follow-up studies are warranted for each of the recess strategies identified to be effective.

Background:

The purpose of this study was to determine the effectiveness of Ready for Recess: an elementary school recess intervention targeting staff training (ST) and providing recreational equipment (EQ).

Methods:

Ready for Recess had 4 intervention schools: 1) EQ+ST, 2) EQ, 3) ST, and 4) control. Moderate-to-vigorous physical activity (MVPA) was assessed with accelerometers at the four schools in 257 3rd- to 6th-grade children. Random intercept models for overweight/obese (OWOB) and healthy weight (HW) for boys and girls separately, examined change in percentage of time spent in MVPA during recess across EQ+ST, EQ, and ST compared with the control from baseline to postintervention.

Results:

HW boys receiving EQ+ST increased MVPA by 19.4%, OWOB boys receiving ST increased MVPA by 4.5%, OWOB girls receiving EQ-ST increased MVPA by 6.0%, while HW girls receiving EQ decreased MVPA by 13.6% in comparison with the control.

Conclusions:

Ready for Recess represents a possible means to increase MVPA in OWOB girls/boys, populations least likely to meet MVPA recommendations. However, the effect of the intervention was not uniform across all subgroups.

We used achievement goal theory to examine students’ physical activity (PA) motivation and physical education (PE) enjoyment. Purposes included: 1) determine whether schools with different pedagogical approaches varied in student perceptions of mastery and performance climate dimensions, enjoyment, and PA; 2) examine gender and grade differences in enjoyment and PA; and 3) determine if dimensions of motivational climate predicted enjoyment and PA levels in PE, controlling for gender and grade. Youth (n = 290, 150 girls) from three southeast United States middle schools wore a pedometer and completed a motivational climate and enjoyment questionnaire. Boys were more active and enjoyed PE more than girls, and 7th/8th grade students were more active than 6th grade students. Enjoyment was positively predicted by teacher’s emphasis on two mastery climate dimensions, controlling for gender. PE activity time was predicted by two performance climate dimensions, controlling for gender and grade. Implications for practice are discussed.

Background:

Current recommendations call for adults to be physically active at moderate and/or vigorous intensities. Given the popularity of walking and running, the use of step rates may provide a practical and inexpensive means to evaluate ambulatory intensity. Thus, the purpose of this study was to identify step rate thresholds that correspond to various intensity classifications.

Methods:

Oxygen consumption was measured at rest and during 10 minute treadmill walking and running trials at 6 standardized speeds (54, 80, 107, 134, 161, and 188 m·min-1) in 9 men and 10 women (28.8 ± 6.8 yrs). Two observers counted the participants’ steps at each treadmill speed. Linear and nonlinear regression analyses were used to develop prediction equations to ascertain step rate thresholds at various intensities.

Results:

Nonlinear regression analysis of the metabolic cost versus step rates across all treadmill speeds yielded the highest R 2 values for men (R 2 = .91) and women (R 2 = .79). For men, the nonlinear analysis yielded 94 and 125 step·min-1 for moderate and vigorous intensities, respectively. For women, 99 and 135 step·min-1 corresponded with moderate and vigorous intensities, respectively.

Conclusions:

Promoting a step rate of 100 step·min-1 may serve as a practical public health recommendation to exercise at moderate intensity.

Siedentop and Locke (1997) proposed three critical elements that must exist in our profession to make a difference and achieve systemic success in physical education (SSPE): (a) quality PE in the schools, (b) effective physical education teacher education (PETE) programs, and (c) a working relationship between the two. Using Cuban’s (1992) curriculum change and stability framework, this qualitative study examines the existence of a program that has achieved all three elements in the southwestern US. For over three decades some seventy-two teachers in dozens of schools have yearly served over 40,000 children. This study revealed a fully functioning model consisting of four key, interdependent components driven by a system of accountability measures. The results of the SSPE model—quality PE for children—is achieved by (a) district-wide mandated curriculum, methodologies and language, (b) well-defined district PE coordinator roles, (c) a partnership university, and (d) frequent, ongoing professional development. Results of this study strengthen Siedentop and Locke’s (1997) recommendation for collaborative efforts between universities and partner school districts and provide a model to guide and manage the curriculum change process in K-6 PE.

Background:

After-school programs (ASPs) across the nation have been asked to increase the amount of activity children accumulate during such programs. Policies/standards that benchmark the amount of total activity (light-to-vigorous physical activity, LVPA) and moderate-to-vigorous physical activity (MVPA) accumulated in an ASP have been developed. Little is known about the prevalence of children meeting these goals.

Methods:

Children (N = 812, 6 to 12 y old) attending 19 ASPs wore accelerometers for 4 days while attending an ASP. LVPA and MVPA were dichotomized according to existing ASP policies/standards. Data on whether a policy/standard was met were compared between gender, age, BMI, race/ethnicity, and ASP-type (faith-, school-, community-based) using mixed-model logistic-regression.

Results:

The prevalence of meeting an LVPA policy/standard ranged from 75.4% (National Afterschool Association [NAA], 20% of program time spent in LVPA) to 97.8% (NAA, 20% of time in attendance spent in LVPA), and meeting an MVPA policy/standard ranged from 0.3% (California, 60 min MVPA/d) to 26.9% (North Carolina, 20% of attendance spent in MVPA). Boys, younger children, nonwhites, and children attending faithor community-based ASPs were more likely to meet any policy/standard.

Conclusion:

Current practice in ASPs is sufficient to meet LVPA policies/standards but insufficient to meet MVPA policy/standards. Efforts must be directed toward identifying the most appropriate policy/standard and strategies to meet it.

Background:

Recess is an important component of a Comprehensive School Physical Activity Program, providing approximately 1268 and 914 steps for boys and girls, respectively, within a 15-minute time period. The purpose of this study was to determine the contribution of unstructured recess on children’s school-day physical activity levels and to examine if recess and school-day physical activity levels varied by BMI, gender, and grade level.

Methods:

One-hundred sixty third- to fifth-grade students from 2 elementary schools wore pedometers during 4 recess periods.

Results:

Recess accounted for 17% to 44% of school-day step counts. There was a significant main effect for grade level, but not for BMI or gender, on the percentage of school-day steps accumulated during recess.

Conclusions:

A 15-minute recess makes a valuable contribution to children’s school-day physical activity, especially for the least active children. More research is warranted to determine environmental influences on children’s recess physical activity.

Little is known about the exact contribution of physical education (PE) to total daily physical activity (PA) among children and adolescents. Therefore, the purpose of this study was to describe the PA of middle school students during PE and non-PE days and determine if children would compensate for a lack of PE by increasing their PA later in the day. Two hundred seventy nine students (159 boys, 120 girls) wore pedometers (Walk4Life LS252, Plainfield, IL) during 5 school days, with at least two of the days including scheduled PE. The least (~1,575; 31% increase), moderately (~2,650; 20% increase), and most highly active students (~5,950; 34% increase) accumulated significantly more daily step counts on days when they participated in PE. Nearly three times the percent of boys (37%) and more than two times the percent of girls (61%) met the recommended steps/day guidelines on days when PE was offered. Rather than a compensatory effect, the most highly active students were more active on school days with PE, even after accounting for the steps they accrued in PE. The evidence is consistent with other studies that have found that PE contributes meaningfully to daily PA, that youth do not compensate when they are not provided opportunities to be physically active in school-based programs, and some youth are stimulated to be more active when they participate in school-based PA programs.
