Outline of Final Research Achievements |
This study assessed medium- and high-intensity physical activity (MVPA) by examining physical activity longitudinally (2019-23) in elementary school students (87 students). Significant decreasing trends by grade level were observed for the number of steps taken during interwork breaks and lunch breaks. There was no decreasing trend in number of steps or MVPA in school as students moved up in grade. On the other hand, the number of steps and MVPA during interschool recess, lunch, and lunch break tended to decrease with grade level, indicating that in-school physical activity tracks relatively more strongly with boys than with girls.

Academic Significance and Societal Importance of the Research Achievements |
小学生を対象に、身体活動量を同じ対象者で経年的に追跡した研究報告は少なく、歩数・MVPAを指標とした身体活動の測度から子どもの発育発達をとらえる上で、経年的な追跡調査による検討は学術的・社会的意義が大きい。
