Abstract:
وجد الباحث ومن خلال المتابعة المستفيضة للمباريات المحلية والعالمية ان مهارة التصويب السلمي ومن القفز هي عامل حاسم ومهم وقوي اذا ما احسن استخدامه وان هناك محاولات تبوء بالفشل بعد تنفيذ التصويب ان اهملت الجوانب الفنية الصحيحة وبذلك برزت للباحث فرصة البحث | Research find from much of studies on many (local and global) games in basketball that is two of important skill in game - jump shoot and lay up shoot - they are very impact factor to get result in any competition if its useful practiced, and it may failed if we ignored many of this factors may influence on it. So, there is a problem bring up for the research to solve it and for identify on the right sides may help us to make a perfect performance that may got better result. It may be and visual factors look like high, speed, angles or accelerate, or insider like strength, impulse, torque or the relation between force - time. As well as Instantaneous Impulse.The aims of study : 1. Identifying some biomechanical variables via three dimensional analysis during the performance of jump and lay up shooting.2. Identifying of Instantaneous impulse by accuracy of jump and lay up shooting.3. Identifying the relationship among the Instantaneous Impulse and some biomechanical variables with accuracy of jump and lay up shooting.4. Identifying the relationship between the Instantaneous Impulse and some biomechanical variables.The researcher hypothised the following : 1. There is statistically significant relation between the Instantaneous Impulse and accuracy of jump and lay up shooting.2. There is statistically significant relation between proficiency of Instantaneous impulse and some bio - mechanic variables via three dimensional analysis by accuracy of jump and lay up shooting.3. There is statistically significant relation between precision of Instantaneous impulse and some bio - mechanic variables via three dimensional analysis in by accuracy of jump and lay up shooting.Field of the Study : - Human Scope : a sample of Oil club premiere basketball club in Iraq in 2014 - 2015. - Periodic Scope : from 24/8/2014 to 2/9/2015. - Spatial Scope : Alshaab closed Hall in Baghdad.Research Methodology and Field Procedures : The researcher adopted the descriptive approach of associative relations so as to achieve the study results. The experiment is conducted on a sample of Oil club basketball players in the premiere league. Four players are selected according to their playing position. A codified test is used to measure accuracy during hierarchical and fro jump shooting. The researcher, as well, made use of the following modern devices and techniques in data processing : - The use of Dynafoot which is regarded as one of the modern tools used to measure pressure and force on a specified area during each step in continuous periods. The researcher used this device according to the instructions of the producing company by inserting a rasher that is containing highly pressure energetic cells under the player's feet inside of his shoes. - The researcher also adopted the three dimensional analysis with the aim of achieving the highest accuracy possible via an analysis of some variables like heights and angles relying on the AutoCAD. - A high speed camera (210 pic per second) is also used in order to have accurate video - taping to check the minutest details during movement.Furthermore, some bio - mechanic variable are chosen depending on the experience of the supervisor and topic approval committee. Regarding Instantaneous impulseing, it is selected after the researcher's consideration of previous studies. After a thorough study, both the supervisor and the researcher agreed on choosing it in addition to the fact that it was also approved by the topics approval committee. The researcher used modern sources to reinforce what is mentioned in the thesis and devices were synchronized together to achieve accurate results in order to be statistically processed via the SPSS The most important recommendations are : - Adopting the scientific approach in analyzing faults and following the objective way in setting appropriate solutions depending on modern tools and methods. - In the case of jump - related - movements, which are characterized by explosiveness, the collision formula should be used in measuring power quantity (impulse=power by its time of influence) which is considered the most objective in measuring power amounts. - Adopting results of studies in evaluating and correcting available or expected mistakes as they are gained according to scientific issues, in addition to focusing on priorities in technical sides starting from the most important to the important.
