تقويم متغير مسافة الرمي من الثبات و الاقتراب و أثرها على قيم بعض المتغيرات الكينماتيكية في فعالية رمي الرمح للرماة الأبطال

الملخص EN

The message contains the introduction to the world going through the rapid development so that it has become difficult for some to keep up with that and this is because of the openness to science by the human after it was in previous periods and in order to achieve that and had the science of Biomechanics the great role in this matter, and the importance of study can contribute to the events of evolution At the level in case of identifying defects and try to repair them by providing information to the trainers and shooters themselves, the problem of research and through the follow-up researcher and being a spearmen noted there is weakness in the shooters that the distance of the throw of stability is a certain percentage of the distance of throwing at Performance of regular firing stages.

The researchers aim to: 1.

Evaluate the variable distance of throwing the fixed and approaching the effectiveness of throwing javelin heroes.

2.

Evaluate the efficiency of linking the two stages of approaching and throwing in the effectiveness of throwing javelin for champions.

The researchers assume: - The effect of linking between the approach phase and throwing on the values of some biomechanical variables on the position of throwing the effectiveness of throwing the spear The results were presented, analyzed and discussed in chapter IV The researchers concluded that some of the members of the research sample used the correct mechanical variables, especially the starting angle of the spear and its use during the placement of throwing in the movement and achieve a good achievement, unlike some members of the research sample was the starting angle of the spear is very large.

The researchers concluded by emphasizing the use of the results of the current study during the training and benefiting from it by the trainers
