Objective: Does learning outside the classroom (LOtC) in urban nature or cultural contexts one day per week contribute to raising children’s physical activity (PA) in lower secondary school?

Methods: PA was measured on 7 consecutive days using GT3x+ accelerometers. Overall, 44 girls and 40 boys from grades 4 to 6 participated.

Results: Significantly higher PA levels were measuredon days with LOtC compared to standard school days (12.4%; p < .001). When excludingthe class using a nature setting, there was no difference in PA on LOtC days compared to standardschool days. The mean PA levels among boys were significantly higher than girls in all measuredsettings except on days with PE.

Conclusion: LOtC in a nature setting may promote PA inschoolchildren.
