 This study examined the physical activity levels of students aged 9 to 23 years old and found that they spent significantly more time being sedentary than engaging in moderate to vigorous physical activity. Additionally, the study found that there was a significant difference between the amount of physical activity performed by students depending on their school segment. These findings suggest that interventions aimed at increasing physical activity levels among students should take into account the unique needs of each school segment.
