  1. Data presented as median (interquartile range). Comparisons between sex and age groups were completed using ANOVA when data was normally distributed and Mann–Whitney U-test for non-normally distributed data. Y,%: percentage of participants who answered yes. *Data only for subjects who reported participating in these activities. SS: school sport; CS: club sport; MVPA: school and club moderate-vigorous physical activity. aP < 0.05, bP < 0.01 and cp < 0.001 for boys vs. girls in the 11-12-year age group; AP < 0.05, BP < 0.01 and Cp < 0.001 for boys vs. girls in the 14-15-year age group; dP < 0.05, eP < 0.01 and fp < 0.001 for differences between the age groups for boys; DP < 0.05, EP < 0.01 and Fp < 0.001 for differences between the age groups for girls.
