Individual and day-to-day differences in domain-specific physical activity of 10- to 11-year-old children in Denmark-Measured using GPS and accelerometry.

The school domain contributed the most to children's MVPA-levels followed by the domains of home, other, and transport. Our study indicated that PA-levels and the distribution of PA across domains differ from day-to-day. Future interventions should target more than one domain to accommodate these individual- and day-to-day differences in the goal of increasing PA-levels and to reduce the decline in PA seen from childhood to adolescence.
