[Background and Purpose] It has been pointed out recently that the issue of declining physical fitness occurs even in young children. As a background, some decline in physical activity and changes in daily life rhythms have been noted. While there have been experiments examining exercise performance and lifestyle improvement in young children, their daily activity pattern has not yet been considered. Therefore, the purpose of this study was to classify the daily patterns of activity intensity and to examine the relationships between these patterns and steps, lifestyle, and health status in young children. [Method] Participants were 386 young children. We measured activity intensity during each weekday using the Lifecorde GS (Suzuken Corporation). We classified participants by activity intensity per hour, using a non-hierarchical cluster analysis with the k-means method. The differences in the daily patterns of activity intensity were confirmed using a two way ANOVA. In addition, the relationships between the daily patterns of activity intensity and steps, lifestyle, and health status were confirmed by an ANCOVA, cross tabulation, and chi-square test. [Results and Discussion] The participants were classified into two clusters and a significant difference in the daily patterns of activity intensity was confirmed. Further, a significant difference in the average number of daily steps was confirmed. The clear difference was not confirmed in a part of lifestyle and health status between two clusters.
