Outline of Final Research Achievements

The purpose of this study was to develop the intervention program to reduce the time spent in a sitting position and increase the amount of physical activity by encouraging young children to change their posture, and to objectively evaluate the effect of the intervention by using ActiGraph GT3X+ accelerometers. In this study, we examined the intervention effects of using "music" as a trigger to encourage postural changes from a sitting position and to naturally move the body. The results showed that the intervention had no effect on the duration or ratio of sedentary behavior, light physical activity, or moderate-to-vigorous physical activity.

Academic Significance and Societal Importance of the Research Achievements

幼児おける身体活動不足は世界中で問題となっており，これは主に座位行動で過ごす時間に起因することが指摘されており，その改善方法を検討することは重要である．そこで本研究では，幼児の身体活動促進や座位行動抑制に繋がる保育施設内で実施できる介入方法を検討するために音楽利用の効果を検討した．その結果，座位行動，低強度身体活動，中高強度身体活動のいずれの活動時間や活動割合にも音楽を利用した介入の効果は見られなかった．今後は，取り組みに用いる楽曲や音楽を流すタイミング，時間などを詳細に検討する必要性が示唆された．
