تاثير اوزان مختلفة في بعض المتغيرات الكينماتيكية لاختبار قوة الذراعين

Abstract EN

The study aimed to identify the values of the explosive strength testing of the arms with different weights and some of their kinematic variables and their effect on them in addition to the level of differences that affect performance and its variables among students of the College of Physical Education and Sports Science - Baghdad University in the year (2018-2019) m, and by informing the researchers on Various scientific sources, he did not find a similar study that takes the differences of weights in achievement and the mechanical path of performance.

Also, when we take the test requirements, we find that there are sources that give importance to this type of testing in knowing the explosive strength of the arms, but they do not apply in weight (the ball Medicinal) which is used for testing, some of them give a weight of (1) kg and the other (2) kg and the other (3) kg.

, knowing that it is for the same sample in terms of age or level, it is true that we may consider weight cases when the age of the sample differs.

The researchers used the descriptive method in the method of comparisons.

The sample consisted of (100) students distributed over the four stages.

The experiment was conducted in the closed indoor hall.

The sample conducted the tests on (3) different weights in throwing the medical ball (1) kg, (2) kg (3) kg from the (sitting) position.

A camera was used at a speed of (120) p/s in addition to analyzing the variables by means of the kienovea program.

The results were extracted using the statistical program (SPSS) (One.

And they concluded that there are constant decreasing proportions in the amount of research variables between different weights, and that the starting speed is the most influential variable after achievement in the difference of weights.
