Abstract Introduction:<\b>
The Chilean Ministry of Sports initiated a national programme in 2014 which consists in hiring specialists to provide 3 PE lessons/ week to low income preschool children during the school year.Objective: to compare MVPA accumulated by the most active versus the least active children during PE lessons and during school time, by gender.Methodology: in 2015, this programme was implemented in 92 preschools. We selected a sample of 532 five y olds from 66 preschools. 4-5 children wore accelerometers (Actigraph GT 3X) during a school day which included a PE lesson. PA intensity was determined with Butte cut points. Results shown originate from 164 lessons and correspond to one child during one school day. We categorized the children into the most active and least active ones by percentile MVPA accumulated during PE lessons (P75 and P25 respectively) and compared MVPA accumulated by each group during PE lessons and school time, in each gender, using t-tests. Results:<\b>
In PE classes, P75 vs P25 boys accumulate 56.8 and 16.7 % MVPA, while girls accrue 47.1 and 11 % respectively (p<0.001); during school time, these % were 18.6 and 12.1 % for boys and 13.9 and 9.3 % for girls (p<0.01). Girls accumulate significantly less MVPA both during PE lessons as in school timeConclusion:<\b>
more active children surpass the recommended MVPA during PE lessons and accumulate significantly more MVPA during school time. It is important to find out why some children are inactive (especially girls) and address those issues.
