What is it about?

Have you ever wondered how children and teenagers spend their days can impact their health? A recent study examined the different volume and intensity of activities performed during school days and weekends and their potential association with weight-related issues in young individuals. The study yielded some interesting findings by tracking the movement behaviours of a group of children and adolescents. It was discovered that children and adolescents tended to be less active on weekends compared to school days. Interestingly, the study also found that the way they moved on different days was linked to their body weight. When kids were more active during school days, it was associated with lower levels of body fat. On the other hand, higher activity levels during weekends were linked to unfavourable weight status.

Why is it important?

Our findings suggest that maintaining a balanced and active lifestyle throughout the week is essential for preventing weight-related problems in children and adolescents. We can support their overall health and well-being by encouraging regular physical activity.


Promoting active lifestyles for children and adolescents is vital for healthy development in today's sedentary society. The recent study highlighting the differences in activity profiles between school days and weekends provides valuable insights into the impact of 24-hour movement behaviours on weight-related issues. With decreased activity levels on weekends, there is a risk of increased sedentary behaviours, contributing to weight gain and obesity. To address this, it is crucial to create environments that encourage physical activity through initiatives like active play, physical education in schools, and family engagement in active pursuits. By prioritizing regular physical activity, we not only prevent childhood obesity but also enhance cognitive function, emotional well-being, and social interaction.
