The purpose of this study was by obtain knowledge to select an appropriate practice method for learner clarify the technical elements what can be a mastered in each practice methods. In this study, I focus on the three typical practice methods of spike : 1）A mark on a floor that proper movement of the foot for approach to take off and a learner trace the mark, 2） A normal method to hit the ball at taking off from approach, 3）A learner bound down from the 30cm box and take off.
The main results of this study were as follows;
1） In the practice method using the marker, it is possible to learn the foot position of approaching and taking off. But the step width varies
depending on the learner, so it is necessary to set the position of the marker suitable for each learner.
2） It was reasonable to support that a normal practice was appropriate to bring out raising motion of the body during the taking off for higher
jumping.
3） It was reasonable to support that it turned out that the normal practice method is appropriate in order to learn the accelerated approach and
the taking off.
4） The amount of movement at the taking off was increases in the practice method using a box. But it’s necessary to take notice that the knee
joint flexion angle tends to be excessive.
5） It is necessary to make the connection from the approach to the taking off, motion in the air for the task of spikes in a better form by the
normal practice.
6） It become clear that a normal practice was more appropriate, if you want to turn the direction of the leap upward,
