Impact of the Special Momentary Strength Trainings in some Bio mechanic Indicators and the Accuracy of Touching for Lunge and Arrow Movements of Young Fencers

Abstract
All types of power including the special momentary power are considered one of the most bodily features in most sports including fencing sports that mainly relies on both movements: lunge and arrow. It is not possible to a player to apply the plans and attacking skills without acquiring accuracy lunge and arrow movements. Thus,, performance without accuracy may not be useful for the weapon may not touch the target. Therefore, accuracy is considered one of the most important factor in fencing sports.
Through the researcher work’s, experience, and his continuous following to youth class, he noticed that there is deceleration in the fencer’s speed and shortage of starting, as well as weakness in the accuracy of touching the target especially in attacking movements like the lunge and arrow movement. This is in addition to unavailability of real data or bio mechanic indicators that the coach depends on. Thus, the researcher wanted to discuss this problem to find the suitable solutions through knowing the influential bio mechanic indicators in performing the lunge and arrow movement as well as designing trainings in accord with what skillful performance of stabbing spears require to develop some bio mechanic indicators and touching accuracy of the lunge and arrow movement of young fencers.
The research aimed at preparing special trainings of momentary power to recognize its impact on some touching accuracy of the lunge and arrow movement of young fencers. The researcher used the experimental approach by designing the equal groups ( the experimental and the controlled) to suit the research nature and problem.
concerning the research sample, it is represented by the classified from 16 to 20 years with fencing sword who were divided into two groups: the experimental and the controlled. Then, special trainings were prepared to develop and improve values of the bio mechanic indicators and touching accuracy of the lunge and arrow movement. The special suggested trainings were implemented within 8 weeks with an average three training units per week. later, the backward and tests were done. After that, the suitable statistical treatments were used to reach the results.
The researcher concluded that the experimental group achieved better results than the controlled one relating values of all bio mechanic indicators and touching accuracy of the lunge and arrow movement of the forward tests. This is a good reference of the activation of the special momentary power trainings.
The researcher recommended the necessity of emphasis on basics, conditions, and mechanic principles in designing and building trainings concerning items of the training method according to the performance conditions of the skill that has to be learned, as well the emphasis on using the special trainings due to their positive role in improving values of bio mechanic indicators and the level of the body and skill performance
