기록 도전활동 참여 학생선수의 스타트 방법에 따른 100m 구간속도 비교연구

This study compared the change of 100 m overall speed depending on the starting method of elementary school athlete students by each group, observed the starting area, accelerating run, spurt, fastest speed of each finish section, time to pass a section and speed decrease rate and found the following results. First, students of A and B groups showed faster section speed in the order of Bunch, Medium and Free Start for section speed at 30, 50, 70 and 100 m. Second, the section speed of 100 m at Bunch, Medium and Free Start was faster in the order of following sections: 30∼50 m, 50∼70 m, 70∼100 m and 0∼30 m. Third, B group showed relatively bigger decrease speed rate at the finish section. The students showed faster section speed with starting block method of Bunch and Medium Start than the Free Start method that doesn’t use starting block at 100 m sections. Bunch Start showed relatively faster speed. The speed decrease rate increased after 70 m. It is believed that improving the fastest speed area and maintaining area, speed endurance strengthening training and dynamic starting block usage could shorten the record time.
