Aims: It has been suggested that the COVID-19 restrictions may have negatively impacted physical activity (PA) levels, especially among adolescents, who often use organised sports to support their intrinsic motivation for staying active. This study aimed to investigate whether adolescents were less physically active after the COVID-19 restrictions compared with before and examine whether participation in organised sports has changed since the COVID-19 restrictions.
Methods: This was a retrospective cohort study of Danish adolescents aged 15 to 19 years.
