The purpose of this study is to clarify whether the trunk movement will be acquired and then the relationship between the change of the trunk movement and the sprint time through a unit of “Kakekko” for middle grades of elementary school. The participants were 39 children (21 boys and 18 girls) in 4^th grade and they had 8 classes. ”Mantle-run” and “Mark run” had been carried out to improve the trunk movement. In order to verify the purpose of this study for items were analyzed: sprint time, maximal speed, sprint speed(10-40m), decline rate of speed, and sprint form.<br>

The main findings are summarized as follows:<br>

1. Although the results of formative lesson evaluation showed low values in the first lesson of the unit, they gradually moved to high values. It is suggested that the lesson of “Kakekko” was able to obtain a generally good evaluation from participants.<br>2. As to the upper-skilled children, there were no changes in the trunk score of “Flexion and forward leaning of trunk”, sprint time, maximal speed, sprint speed (10-40m), and decline rate of speed.<br>3. As to the middle-skilled and the low-skilled children, the trunk score of “Flexion and forward leaning of trunk” improved, but the sprint time, maximal speed, sprint speed (10-40m), and decline rate of speed did not change.
