Adolescents who walk to and from school are more active throughout the day compared to their vehicle-riding peers, according to a new study.

Researchers from the United Kingdom measured physical activity among 92 students between ages 13 and 14. They wore accelerators to measure their vertical movement. Study investigators categorized the teens based on whether they traveled to and from school by foot, car, bus or train.

Results show students who walked both to and from school accrued the most minutes of moderate to physical activity throughout the day and were most active during non-school hours. Those who walked only one way were the second-most active group.

Eighty-seven percent of those traveling by some sort of vehicle accumulated an average of 60 or more minutes of moderate/vigorous physical activity on weekdays. Ninety percent of those who walked one way did so, and 100 percent of students who walked both ways accumulated that many minutes.

Researchers suggest walking in the morning may stimulate further activity and students who do so may have a different appreciation of activity than others.

Other studies have shown similar results for younger children, although among 5 year olds, mode of transportation was not shown to significantly affect overall activity level, suggesting that walking to school may be more beneficial for older children.
