Influence of the Simultaneous Training with Different Angled Surfaces of the feet in Developing Bio kinetic Capabilities and Accuracy of Endurance Skillful Performance to Taekwondo Youths

Abstract
Taekwondo sport has many skills that highly depends on work efficiency of the foot muscles including the back kick and the front half circle. To carry out these skills actively, the player has to possess high bodily and mobile abilities. Through the researcher’s field experiment, he didn’t find who cares or thinks in training the activity of the foot muscles and increasing their efficiency; he also didn’t find the serious interest in using the simultaneous training style which may have an active positive role in developing most players’ skills and bodily and mobile abilities. Thus, he worked hard to put the simultaneous training style with presence of different angled surface of the feet which were designed to suit the skillful performance of Taekwondo in developing some biokinetic capabilities; for the sake of this, the study has the following aims.
* Designing different angled surface of the feet and preparing trainings with simultaneous training style of different angled surface of the feet and stating their impact in developing some biokinetic capabilities and accuracy of skillful performance endurance to Taekwondo youths.
* knowing the superiority of impact on trainings by the simultaneous training style of different angled surface of the feet in comparison with the trainings used by the coach in developing some biokinetic capabilities and accuracy of skillful performance endurance to Taekwondo youths.
The researcher used the experimental method so that he can achieve the aims and solve the problem of the study by designing the equivalent groups ( experimental group and controlled group) of the anterior and posterior tests to suit the problem nature under investigation. The researcher limited the research community by Kerbala province team about 24 players who were distributed in the two groups ( experimental group and controlled group) according to what was recorded in Kerbala Taekwondo union. Also, 12 players were used out of the original research community in the reconnaissance research experiment. The equivalence of the two groups
( experimental group and controlled group) was used. The researcher also used some suitable device, equipment, and machines to complete the research. He made reconnaissance experiment. Later, he made the anterior test followed by the selected trainings by the simultaneous training style different angled surface of the feet for 8 weeks with 3 units per week, then, he made the posterior tests and treat them statistically. Based on this, the researcher concluded the following:
The results showed that there are clear influences of the experimental group trainings by the simultaneous training style different angled surface of the feet in biokinetic capabilities and the skillful performance of the two kicks: the half circle front and the back of Taekwondo youths. The results also showed there are influences in the experimental group of the biokinetic capabilities and the skillful performance of the two kicks: the half circle front and the back of Taekwondo youths. The superiority was for the benefit of the experimental group to the controlled group in the biokinetic capabilities and the skillful performance of the two kicks: the half circle front and the back of Taekwondo youths.
The researcher recommend on building power efficiency of the working muscles on the feet correctly which causes change in developing their biokinetic capabilities when dong the two kicks. This is beside making simultaneous training with different angled surface of the feet due to their significance in improving the explosive power and the recognizable speed of the legs, as well as fitness, harmony, balance, and accuracy of performance endurance; the matter that develop the skillful level of the mobile performance to reach the perfect performance
