The analysis of biokenamatical of some variables in javelin throw activity

Abstract:
Aim of study
1. to identify some values of biokenamatical variables in javelin throw activity .
2. to identify the relationship between biokenamatical variables and performance .
hypothesis
- there is a statistical significant correlation between some biokenamatical variables and performance .
methodlogy
- a sample of (5) players of youth clubs championship of track and field in javelin throw activity .
- the study was analyzed by using video tape
- certain statistical methods were used .
results and recommendations
on the basis of the analysis of the data , the following conclusion were presented
- there is a significant correlation between starting speed and performance .
- there was no significant correlation between starting angle and the height of starting point with performance .
- there is a significant correlation in variables of (length, time and speed) of pivot point .
- there is a significant correlation of angle speed and speed of throwing arm with performance .
- there was no significant correlation in variables of bending trank angle with performance.
