The aim of this research is to find out the amount of VPA, which is performed by adolescents during the school days regard to the gender and age. 191 girls and 79 boys participated in the research. Accelerometer ActiTrainerTM was used to monitor physical activity (PA) and heart rate (HR) during whole school day. School days were divided into five day periods (before school, school lessons without physical education (PE), PE classes, school breaks, and after school). Results confirmed the presumption that boys had more VPA than girls during school days in periods before school, PE classes and also during whole day. Older boys spent the longest period of time in the level of VPA compared to other age groups. PE classes were found out as a day period, where participants had in average highest values of spent time in the level of VPA. VPA was detected during school breaks, school classes, PE classes, in time before school and after school. Only 16.5 % of boys and 4.2 % of girls reached total amount of 20 minutes of VPA during whole day. VPA is a significant component of daily PA in school days of the most adolescent boys and girls. However the results are showing a lack of VPA in both genders, mainly in girls. The results also suggest that PE classes are providing a substantial role of the VPA in the daily PA in adolescent boys and girls during school days." .
