Young children are getting less exercise than we thought.
A new study out of Europe looked at data on 600 children between the ages of six and 11.
Researchers say many of the children saw a decrease in physical activity, as well as an increase in sedentary time, at age eight.
This is a change from previous studies that showed a decrease in activity around the time they become teenagers.
The new study found an even larger drop-off in exercise happened once children reached age 11.
Study authors say the findings highlight the need to look closer at how video games and phones are impacting physical activity.
Complete results of the study can be found in pediatrics.
