Abstract
Abstract The skill correction of jumping skills important and difficult , especially if the distance is far should the player when the correction to be facing the net to allow him the freedom to correction and this requires the performance of movements are important in parts of the body work on the change in the speed and thus increase the speed of the ball , which is one of the things important correction in certain situations , so to be moving some parts of the body in order to get the speed utilized in the correction , which passes them on to the tool , a ball , and should speed the correction caused by the transport motor of the lower limbs to the arm aimed at requiring it to increase the speed of the ball , trying economy resulting in the least effort possible period of time is conditional on the successful correction . The study aimed to: 1 - Identify the values of angular momentum leading man ball speed when performing skill shooting jumping high handball and both cases in a sample search. 2 - To identify the contribution of angular momentum (the momentum) of a man leading a change in the speed of the ball and both cases when performing shooting skill of jumping high in a sample search 3 - To identify the differences in the values of a variable of angular momentum (the momentum) of the man leading the variable speed of the ball and in favor of pulling the man down when performing skill shooting jumping high handball between both cases in a sample search. I have used a descriptive approach to solve the problem in a manner survey research and the research sample included players club SoC handball 2013-2014 AD's and (5) players The back line has been the main experiment to search on 11/26/2013 AD at seven pm and the hall closed Club SoC sports in the province of Basra, were used video camera during the trial and also use your program مجلة كلیة التربیة الریاضیة للبنات المجلد 13 العدد 4 عام 2014 analyze mathematical skills (Dart fish) to extract the variables biomechanical, and after processing the data to a computer on according to the statistical program SPSS Ver 8, was reached a set of conclusions, including: 1 - The movement of the bending and extension of the two men for a moment shooting contribute to the transfer of the amount of movement to the ball, which means an increase in the speed of the ball when performing shooting of the high jump. 2 - The amount of traffic generated by the two men in the movement of flexion and extension of the crease to be larger than in the case of non-bending and the form in which the tide marks in the style correction. In light of the findings the researchers recommend the following: - 1 - Make sure the players at training on the performance of the bending and extension of the two men when performing shooting of the high jump adds to the speed of the ball and by the requirements of the situation in the games. 2 - what came to be added by the researchers of the results to the literature of handball and the distinction between methods which contribute to the creation of a base of players who are able to perform more effectively shooting
