I investigated how to instruct long jump effectivery to student at first, two groups (experimental and comparative) wrere devided, and for 12 weeks we traineded the students belong to the experiment under the systematic instruction, but the comparative didn´t.
Through the six times progress check, concluded like followings.
1. In the case of middle school student, 25~30 was suitable as the assistance jumping distance in the experimental group.
The 1st 2nd target distance in the highest speed was 20~5 m (15 m).
2. The foot rolling position is most suitable 40~60 angal on the earth and center of body. Required to raise for tibias the direction as strong as you can.
3. The experimental group showed the 86 cm advance from the first to the sixth times. Every record is tended to have the progressive curve.
4. The advance of comparative group does not contain important meaning when I see natural increase.
According to this, for the record advance its very important to emphasize the assistance jumping distance and foot rolling speed.
