Data are presented as estimated means (SE) from linear mixed models.
*Difference in differences estimated changes (postprogramme/12 months_intervention – baseline_intervention) – (postprogramme/12 months_control – baseline_control).
†Models were adjusted for baseline values, sex and accelerometer wear time.
‡Models were adjusted for baseline values and sex.
LIPA, light-intensity physical activity; MS, maximal strength; MVPA, moderate-to-vigorous physical activity; NA, not available; VO_{2 max}, maximal oxygen uptake.
