RESEARCH OF MOVEMENT’S CONSTANCY AMONG PRIMARY SCHOOL CHILDREN IN CONNECTION WITH SERIAL JUMP

Abstract

We examined serial jump among 12-14 years old primary school children.
The trial was: stending jump with both legs ten times. We measured evry 10
jump / student. We examined the stability and accuracy of movement (jumping).
We created the accuracy index (p=average/dispersion). This index show me the
constancy of movement.
We have some questions:
How can we feature the performance of jumping and constancy of jumping
among primary school children?
Can we find a strong connection between performance and movement
steadyness?
Can we find a big difference between sexes and ages in connection with con-
stancy of performance and movement steadyness?
