Can we skill and activate children through primary school physical education lessons? "Move it Groove it"--a collaborative health promotion intervention.

BACKGROUND: Physical education (PE) lessons are an ideal setting to improve child fundamental movement skills (FMSs) and increase physical activity (PA) for optimal health. Despite this, few studies have assessed the potential to do both simultaneously. The "Move It Groove It" primary school intervention in New South Wales, Australia, had this opportunity. METHODS: A whole school approach to implementation included establishment of school project teams, a teacher "buddy" system, project Web site, teacher training workshops, and small grants for equipment. The quasi-experimental evaluation involved 1,045 year 3 and 4 children (aged 7 to 10 years) in nine intervention and nine control rural primary schools (53% boys/47% girls). It utilised pre- and postobservational surveys of (1) mastery or near mastery levels for each of eight FMSs, (2) proportion of PE lesson time spent in moderate to vigorous PA (MVPA) and vigorous PA (VPA), and (3) teacher- and lesson-related contextual covariates. Data were analysed by hierarchical logistic multiple regression. RESULTS: For FMSs, overall mastery or near mastery level at baseline was 47% ranging from 22.7% for the overarm throw among girls to 75.4% for the static balance among boys. The intervention delivered substantial improvements in every FMS for both genders ranging from 7.2% to 25.7% (13 of 16 comparisons were significant). For PA level, mean MVPA at baseline was 34.7%. Baseline MVPA for boys was 38.7% and for girls was 33.2%. The intervention was associated with a nonsignificant 4.5% increase in MVPA and a significant 3.0% increase in VPA. This translates to a gain of <1 minute of MVPA per average 21-minute lesson. CONCLUSIONS: This is the first study to show that by modifying existing PE lessons, significant improvements in FMS mastery can be gained without adversely affecting children's MVPA and VPA. To increase PA levels, we recommend increasing the number of PE lessons per week.

How active are rural children in Australian physical education?

Physical education lessons offer a venue for children to accrue valuable and health-conferring time being physically active. The first Australian direct observational data are presented on activity of year 3 and 4 children during physical education. Analysis accounts for the nested nature of the data through multi level logistic regression using 13,080 records within 231 lessons within 18 randomly selected schools. Activity was analysed in relation to lesson context (focus of lesson), child gender, school year of child, teacher gender, lesson duration and start time. Children spent 36.7% of a lesson in moderate to vigorous and 12.9% in vigorous activity. Most of the lesson was spent in the context of management/instruction (37.4%), followed by games (25.0%), skill (21.4%), and fitness (14.7%). The highest level of moderate to vigorous activity was observed in the fitness lesson context (61.9%). followed by skill (46.4%), games (42.6%) and management/instruction (17.1%). Moderate to vigorous activity was significantly higher for boys than girls. There was no significant difference in moderate to vigorous activity in lessons led by male or female teachers. However vigorous activity was significantly higher for female led lessons. Children participated in less physical activity during physical education lessons timetabled in the afternoon, compared to physical education lessons time-tabled in the morning. Physical activity levels were not related to lesson duration. Physical education lessons can potentially be more active. However improvement rests on school capacity and may require a health promoting schools approach to implement curricular policy.

Active school playgrounds-myth or reality? Results of the "move it groove it" project.

BACKGROUND: School playgrounds during break times provide potential opportunities for children to be active during the school day. However, there is limited research on how active children really are during these breaks. METHODS: The CAST (Children's Activity Scanning Tool) instrument was developed, validated, and used to assess the percentages of children engaged in moderate to vigorous physical activity (MVPA) and vigorous physical activity (VPA-a subset of MVPA) in 18 primary schools (children ages 5-12) in rural Australia. Related environmental factors were also measured. RESULTS: For a school of median size (200 students), 51.4% of boys and 41.6% of girls were engaged in MVPA while 14.7% of boys and 9.4% of girls were engaged in VPA. Levels of engagement in MVPA and VPA were significantly higher during lunch periods than during recess. MVPA and VPA engagement in smaller schools was significantly higher than in larger schools. CONCLUSIONS: With growing concern about children's physical activity (PA), school playgrounds offer an opportunity to increase children's MVPA engagement especially among girls. Consideration may be given to the lengthening of recess periods in order to increase PA levels. More research is needed to investigate factors affecting PA levels in larger schools.
