| Research Abstract |
The main focus of sprinting in physical education classes at elementary school is acquiring running skills, competing with their classmates, and improving their sprint times. According to the teaching guidelines for elementary schools compiled by the Japanese government in 1980, sprint distances are 50 to 80 meters for third- and fourth-graders (aged 8 and 9) and 80 to 100 meters for fifth- and sixth-graders (aged 10 and 11). The guidelines suggest that the distances should be run all out from beginning to end. However, in the new guidelines revised in 2002, the distances were shortened to 40 to 60 meters for third- and fourth-graders, and 50 to 80 meters for fifth- and sixth-graders. The government's intention to bring the distances in closer line may be based on with students' kinetic drive and physiological characteristics. However, the government has given no clear explanations on the rationale for the changes.
The purpose of this study was to clarify the characteristics of students' mental and physical responses to sprints of different distances. After each 40, 60, 80 and 100 m sprint, the exploratory and confirmatory factor analysis was applied to 195 boys and girls. A questionnaire (SD technique) was 20 items, regarding their consciousness after each sprint. The heart rate as objective measures of exertion, and Borg's PRE scale as a subjective measurement of exertion were carried out.
All the subject groups evaluated the 40m sprint as "light exercise," the 60-meter sprint as "just right," the 80-meter sprint as "a little tough" and a 100-meter run as "severe." Based on all the data, a 60m sprint, which all subjects were able to run at the maximum speed without putting too much physical strain on them-feeling it "fulfillment and sensation." is the most desirable distance. 60 meters should be the standard sprint distance in physical education classes, but shortened or lengthened in accordance with students' abilities.
