School recess playgrounds provide important settings and opportunities
for children to engage in physical activity. The aim of this study was to
describe the daily physical activity (PA) and physical activity during
recess of Primary School children and the relationship with sex and age.
Method. 783 children (379 boys and 359 girls; age=8.5±1.7 years;
range 6 to 11) participated in the study. Daily PA of each child was measured
using a validated questionnaire that was completed by the parents of
each child, whilst playground recess PA was measured using accelerometry.
An ANOVA was used to determine differences by sex in each age
group with confidence intervals and effect sizes. Also MANOVA was used
to analyse the main and interaction effects of age and sex on variables. The
Scheffe post-hoc test was used for comparisons.
Results. Boys reported higher daily PA levels than girls across all age
groups. The differences was bigger in seven (47,6±6,5 vs 42,6±6,4
MET/day; p<0,001), eight (48,5±8,6 vs 41,9±4,6MET/day; p<0,001) and
nine years old (49,8±8,3 vs 44,1±5,9 MET/day; p<0,001). Measured
recess PA was higher for boys compared to girls at age nine (28,4±12,0 vs
23.7±11,8 motion counts; p<0,039), ten (28,5±10,8 vs 23,7±10,0 motion
counts; p<0,014) and eleven years old (24,6±12,2 vs 20,7±9,3 motion
Conclusion. Daily PA is higher in boys compared to girls across all
age groups (six to eleven years old). On the other hand, recess PA was higher
only in boys between nine and eleven years.||
