Lower Levels Of Vigorous Activity Research Articles

Program Evaluation of Environmental and Policy Approaches to Physical Activity Promotion in a Lower Income Latinx School District in Southeast Los Angeles.

There is alarming population wide prevalence of low adolescent physical activity as this represents a risk factor for later chronic disease development. There is evidence to suggest that schools with strong wellness policies have students that are more frequently active. We designed an intervention to enhance students’ physical activity levels in five majority Latinx, underserved school districts. Evaluation consisted of assessment of written quality of school-district wellness policies; observation of student’s physical activity during leisure times; and after-school program practices and policies. We examined one of these district’s results more closely, the only participating district with a community coalition, and extracted lessons learned. On the physical activity section of the wellness policy, this district covered a moderate extent of recommended content areas using weak language. Compared to previous reports, we identified low vigorous activity levels for girls and boys at baseline (respectively, 12% and 18%). Finally, we identified that of four after school program sites assessed at baseline, no program reported the recommended 50% or more of program time dedicated to physical activity. Based on these evaluation findings, additional strategies are urgently needed to encourage all students and particularly more girls to be physically active throughout the school day.

Persistent socio-demographic differences in physical activity among Scottish schoolchildren 1990–2002

Regular participation in physical activity can have significant health gains in terms of physical and psychological wellbeing but there is evidence to suggest that many young people are not sufficiently active to benefit their health. This paper examines the socio-demographic patterning of leisure-time vigorous physical activity among Scottish schoolchildren between 1990 and 2002. The Health Behaviour in School-Aged Children survey of 11-, 13- and 15-year-old schoolchildren has been carried out in Scotland since 1990 at four-yearly intervals. Levels of vigorous physical activity were measured in relation to gender, age and socio-economic status (SES). Girls reported lower levels of vigorous physical activity than boys and this gender difference persisted throughout the four survey years, irrespective of changes in overall levels of physical activity. Vigorous physical activity was also consistently lower among lower SES groups and older adolescents. The effect of gender was greatest, with high-SES girls reporting lower levels of vigorous activity than low-SES boys, and low-SES girls being the least active overall. Scottish adolescent females, especially those from low SES groups, may be at particular risk of the adverse health effects associated with low levels of physical activity. Health promotion programmes to promote physical activity need to address these persistent gender and socio-economic inequalities.

Maturation, Gender, and Video Game Playing Are Related to Physical Activity Intensity in Adolescents: The Muscatine Study

This study examined average daily physical activity and discrete activity intensities in 102 adolescents (age M = 15 yr). Dependent physical activity variables were constructed from minute-by-minute movement counts measured during 4 consecutive days of accelerometry. Independent variables included gender, sexual maturation, TV viewing, and video playing. The stability of 4 days of activity measures ranged from R = .66 to 30. Video game playing was inversely associated with average daily movement for boys (r = −.38) and girls (r = −.55). Boys at all levels of sexual maturation had higher levels of activity than girls. Late and postpubertal boys and girls were more sedentary, had lower levels of vigorous activity, and lower levels of average daily movement than boys and girls in midpuberty.
