"The aim of the study was to characterize school related weekly physical activity (PA) in adolescent girls and to identify the influence of participation in Physical Education lessons (PE) on the structure of weekly PA. The study was carried out using Actigraph monitor and record sheets in a period of five school days and two weekend days. The results have shown that girls participating in two or more PE lessons show higher overall PA performed at school and also spend more time performing intensive PA at school than girls participating only in one or no PE lesson during the week. The girls spent most of the time at school by being physically inactive, on average 125 minutes. Moreover, the results show that school and PA performed there (PE lessons) has still its irreplaceable role in the education system regarding the total level of PA and healthy lifestyle in adolescent girls." . .
