A recent study found that only about 30% of school children are engaging in adequate physical activity during school hours. The study, which involved 17,000 students wearing activity trackers, discovered that most pupils are not meeting the recommended 30 minutes of moderate-to-vigorous physical activity (MVPA) per day at school. Surprisingly, the size of the playground did not have a significant impact on activity levels, challenging the belief that more space leads to more exercise.

The research also revealed that teachers who were more active tended to have more active students, indicating a positive influence on student activity levels. Tim Hollingsworth, a sport professor at the university and former CEO of Sport England, expressed concerns about the findings, suggesting that there is a lack of emphasis on health and activity for young people.

In some schools, students averaged only eight minutes of MVPA, while in others, they exceeded 40 minutes, showing a wide range of activity levels. Boys were generally more active, but in 5% of schools, girls outperformed boys, highlighting variations in activity levels. Lead author Georgina Wort stressed the importance of addressing the health and well-being implications of these findings and the disparities in physical activity levels among schools.

Notably, children in schools located in disadvantaged areas engaged in 25 minutes less MVPA per week. The influence of staff leadership and school culture may play a role in determining student activity levels. Co-author Professor Dylan Thompson suggested using wearable technology to help teachers identify students who may need additional support and to pinpoint sedentary periods during the school week.

The study underscores the need for schools to enhance physical activity opportunities during the school day. Sharing knowledge and best practices among schools could help improve physical activity levels.
