Children’s segmented physical activity and sedentary time during school days, recess, out of school, and weekends across two school years

The majority of Finnish school children need to have a more physically active lifestyle in order to get more health benefits, since three-fourth of 11 to 15-year-olds fail to accumulate at least 60 minutes of moderate to vigorous physical activity (MVPA) on a daily basis. However, these findings are derived from self-reported data, and therefore, objective, physical activity data are needed to better understand the levels and patterns of physical activity and sedentary behavior. The present study extends the previous findings by investigating children’s segmented MVPA and sedentary time using acclerometers across a period of two school years.
