Trends in physical activity in adolescents participating and not participating in organized team or individual...

Participation of adolescents in organized physical activity (PA), together with physical education, is essential for the development of a habit of regular PA, achievement of PA recommendations and adoption of physical literacy. The aim of the study is to identify the trends and differences in PA levels between adolescents participating in organized team PA, organized individual PA, and those not participating in organized PA. Another aim is to formulate proposals to eliminate the negative effects of the pandemic on adolescents' participation in organized PA.

The research took place between 2012-2021 in 51 secondary schools and involved a total of 1,202 boys and 1,561 girls. Participation in organized PA was examined using the 'Sports preferences survey'. Weekly PA was investigated by means of the 'International Physical Activity Questionnaire-Long Form'.

The results confirmed the negative trend in participation in organized PA. However, this was predominantly caused by the negative effects of the pandemic in 2020-2021. Boys participating in organized team and individual PA had more school PA, recreation PA, vigorous PA, moderate PA and overall PA during the week, compared with boys not participating in organized PA (girls had more vigorous PA, moderate PA and overall PA).

Participation in organized team PA and individual PA plays an important role, primarily in supporting vigorous PA but also in overall weekly PA among boys and girls. The negative effects of the pandemic should be eliminated by increasing adolescents' participation in various forms of organized PA with an emphasis on organized individual PA which can be regularly pursued, even under restrictive measures at home, in the countryside or in nature.
