Outline of Final Research Achievements |
The present study examined the associations between walking to/from school with physical activity before school, after school, and during the entire day in Japanese children. A total of 119 participants were investigated regarding their mode and length of school commute and physical activity. Step counts, sedentary time (ST), light physical activity (LPA), and moderate-to-vigorous physical activity (MVPA) were measured using an accelerometer. The results showed that 90.8% and 89.9% of students walked to/from school, respectively. The segments of before school, after school, before and after school, and during the entire day demonstrated significant low to high (r = 0.20-0.86) correlations between the time spent walking to/from school and step counts, ST, LPA, and MVPA. Our results also suggested that children with relatively short commuting time to school need to be more physically active in daily life situations.

Academic Significance and Societal Importance of the Research Achievements |
本研究では,子どもの徒歩通学と始業前,放課後,1日全体における身体活動量との関連を検討した。本研究の結果から,徒歩通学時間と身体活動量との正の相関関係が明らかとなった。特に徒歩通学時間は,歩数と強い関連が,中高強度身体活動と中程度の関連が示された。これらの結果から,徒歩通学の身体活動量に対する重要性が明らかとなった。また,相対的に徒歩通学時間の短い子どもは,日常生活においてより積極的に身体活動を行う重要性が示唆された。
