Moderate-to-vigorous Physical Activity (moderate-to-vigorou + physical_activity)
Selected AbstractsLeisure-Time Physical Activity in Elementary Schools: Analysis of Contextual ConditionsJOURNAL OF SCHOOL HEALTH, Issue 10 2010Thomas L. McKenzie PHD BACKGROUND: Little is known about children's leisure-time physical activity (PA) at school and how it is associated with contextual variables. The purpose of this study was to objectively assess children's voluntary PA during 3 daily periods and examine modifiable contextual factors. METHODS: We conducted SOPLAY (System for Observing Play and Leisure Activity in Youth) observations before school, during recess, and at lunchtime in 137 targeted activity areas in 13 elementary schools over 18 months. During observations, each child was coded as Sedentary, Walking, or Vigorous, and simultaneous entries were made for area characteristics (accessibility, usability, presence of supervision, loose equipment, and organized activities). Logistic regression analysis was used to test associations between PA and area characteristics. RESULTS: Assessors made 2349 area visits and observed 36,995 children. Boys had more moderate-to-vigorous physical activity (MVPA; 66.2 vs 60.0%, p < .001) and more vigorous PA (29.8 vs 24.6%; p < .001) than girls. Areas were typically accessible and usable, but provided organized activities infrequently (16.5%). Odds of engaging in MVPA were greater during lunch and recess than before school and in areas with play equipment (p < .05). CONCLUSIONS: Children accrued a substantial amount of voluntary PA during leisure time at school. Their PA would likely be increased if school playground equipment was more readily available and if supervisors were taught to provide active games and promote PA rather than suppress it.

Gonzalez-Suarez MD ABSTRACT Background:, Little is known about pre-pubescent Filipino children's involvement in moderate-to-vigorous physical activity (MVPA). There are international guidelines regarding required levels of MVPA for healthy children. Methods:, This study describes participation of 11- to 12-year-olds in randomly selected public and private schools in San Juan, Metromanila, in MVPA and sports during a school day. The Filipino-modified Physical Activity Questionnaire for Older Children (F_PAQ_C) was administered in English and Filipino. Additional data was collected on sex, age, type of school, and amount of time spent using television and computers. Children's self-assessment of physical activities (1 question in the F_PAQ_C) was correlated with their cumulative F_PAQ_C score. Results:, Three hundred eighty subjects (167 boys, 213 girls) participated. Participation in MVPA varied between sex and age groups, from 56.1% to 65.0%. Fewer than 10% of participants were very active. The children were more active during physical education classes than at recess or lunch, after class, or in the evening. Walking for exercise, jumping, jogging and running, free play, and dance were most common. Boys, younger children, and private school students most commonly engaged in MVPA. Self-assessed physical activity had modest correlation (r2= 0.21) with cumulative F_PAQ_C score, after adjusting for sex, age, and school type. Conclusion:, Most children were not physically active during the school day, except in physical education classes. To reduce the gap between recommended and current activity levels, more opportunities should be provided for preteen Filipino children to engage in MVPA during and after school.

The case study school was one of 12 randomly assigned to the intervention group. The study intervention was based on the premise that a successful intervention is developed and tailored by teachers and staff to fit the context of their school. Intervention guidelines (Essential Elements) and the Coordinated School Health Program (CSHP) model were used to direct intervention activities for physical education, health education, school environment, school health services, faculty/staff health promotion, and family/community involvement. All girls at the case study school received the intervention. A team of school employees provided leadership to develop and implement the intervention in collaboration with a university project staff. Data collected over a two-year period were used to describe changes that occurred in each CSHP area. Key changes were made in the school environment, curricula, policies, and practices. Qualitative measures showed girls more involved in physical activity. Quantitative measures taken in eighth grade, and repeated with the same set of girls in ninth grade, showed increases in both moderate-to-vigorous physical activity (p = < .01) and vigorous physical activity (p = .04). Other schools can use this case to modify components of the CSHP model to increase physical activity among high school girls. [source] Predicting physical activity and outcome expectations in cancer survivors: an application of Self-Determination TheoryPSYCHO-ONCOLOGY, Issue 7 2006Philip M. Wilson Abstract The purpose of this study was to examine the contributions of autonomous and controlled motives drawn from Self-Determination Theory (SDT; Intrinsic Motivation and Self-determination in Human Behavior. Plenum Press: New York, 1985; Handbook of Self-determination Research. University of Rochester Press: New York, 2002) towards predicting physical activity behaviours and outcome expectations in adult cancer survivors. Participants were cancer-survivors (N=220) and a non-cancer comparison cohort (N=220) who completed an adapted version of the Treatment Self-Regulation Questionnaire modified for physical activity behaviour (TSRQ-PA), an assessment of the number of minutes engaged in moderate-to-vigorous physical activity (MVPA) weekly, and the anticipated outcomes expected from regular physical activity (OE). Simultaneous multiple regression analyses indicated that autonomous motives was the dominant predictor of OEs across both cancer and non-cancer cohorts (R2adj=0.29,0.43), while MVPA was predicted by autonomous (,'s ranged from 0.21 to 0.34) and controlled (,'s ranged from ,0.04 to ,0.23) motives after controlling for demographic considerations. Cancer status (cancer versus no cancer) did not moderate the motivation,physical activity relationship. Collectively, these findings suggest that the distinction between autonomous and controlled motives is useful and compliments a growing body of evidence supporting SDT as a framework for understanding motivational processes in physical activity contexts with cancer survivors.

[source] Trends in body mass in Swedish adolescents between 2001 and 2007ACTA PAEDIATRICA, Issue 3 2009Örjan B Ekblom Abstract Aim: (1) Compare BMI standard deviation scores (BMIsds) in 16-year olds in 2001 and 2007 to assess trends. (2) Describe tracking of BMIsds between ages 10 and 16 years, in a longitudinal 6-year follow-up. (3) Identify possible predictors in 2001 for high BMIsds in 2007 and increase in BMIsds between 2001 and 2007. Methods: A six-year follow-up study on 296 subjects, aged 10 years at baseline and a panel study among 16-year olds. BMIsds was used as the main outcome. Results. No difference in BMIsds in 16-year-old adolescents was found between 2001 and 2007. Strong tracking (r = 0.80, 95% CI: 0.75,0.84) was found for BMIsds between ages 10 and 16 years. Low aerobic capacity and high BMIsds at age 10 years predicted overweight at age 16 years. High BMIsds in 2001 predicted a decline in BMIsds (OR: 0.58, 95% CI: 0.43,0.76) and high level of self-reported moderate-to-vigorous physical activity predicted an increased BMIsds (OR: 1.38, 95% CI: 1.13,1.67). Conclusion: There was no difference in prevalence of overweight plus obesity between the 2001 and 2007 samples. Normal weight and good aerobic fitness in 10-year-old children seems to decrease the risk of elevated relative BMI in 16-year olds. [source] | ||||||||||
