Abstract
Research’s aims: 1 . To realize the values of certain variables kinematics , kinetic ,and as well as force-time function in the main phase of shot-put according to baking guide . 2 . To find the correlation between the kinematics variables and between kinetic variables and between force-time function variables for the main phase of shot-put according to baking guide . 3 . To find the correlation between the kinematics and kinetics variables , and between the kinematics and force-time function variables in the main phase of shot-put according to baking guide . The researchers has applied the descriptive method for its convenience with the nature of the research . The research sample has consisted of (4) shot putters who represented the Nineva team in the shot-put activity, Each putter was given (6) trials according to the international law of track and field games. All the trials were filmed and the best trial was analyzed The researcher has used tests, measurement, scientific technical observation and analysis as means for data collecting. The sample subjects have been filmed by using three video cameras each of which films a part of the activity as well as using the platform of measuring ground reaction prepared for this purpose. as well as using programs such like : ACD See 10 Photo program Manager , Al-Hero soft 2001 program , Auto CAD 2009 program and Paint program , After the analysis was achieved, data were statistically handled by applying SPSS application. Statistical means applied in the research are as follows: (arithmetic mean, standard deviation, Person simple correlation coefficient, variance coefficient and percentage). Research’s Conclusions: 1 . There were significant relationship between the kinematics variables body mass center of gravity's variables in terms of displacement, distance, height and velocity have represented 41.175% of the significant correlations of the kinematics variables in the main phase (7 variables out of 17). 2 . There were significant relationship between the kinetics variables in horizontal thrust , horizontal energy power thrust limited , energy power kidney and implicit in condition the absorb and throw out have represented 66.666% of the significant correlations of the kinetics variables (6 variables out of 9). 3 . There were significant relationship between the kinematics and the kinetics variables at the displace and horizontal velocity ,and displace limited ,and thrust limited , vertical thrust and horizontal ,to movement body mass center of gravity's and , vertical and horizontal energy power, and energy power limited represented 23.77% of the significant correlations between the kinematics and the kinetics variables (6 variables out of 26). 4 . While the time and the area of absorb will be slightly that will be positive yield in the push phase to do with concern liberty force – time variables . 7 . If increase the total time in the main phase to shot – put with method backing glide will be growth the rate of under curve area – time td each phase of phases (hit- absorb- push ) which pigeon block in the technical performance to inquiry needed achievement The researchers has recommended the following: 1 . Confirmation on the performance as much as possible achievement of force generation associated with velocity during the pushing phase to attain the best achievement in shot-put . 2 Taking care of the movement of body mass center of gravity as being the variable that significantly correlated with the largest number of kinematics variables in the main stage of weight shot according to Baking glide . 3 . Developing the body angular velocity during the pushing phase for its positive reactions on real distance of the shot flight trajectory . 4 . Confirmation to use video filming sight and motion analysis from coaching by using new equipment to stand up of the important point of power and feeble to developing technical performance for deferent influences . 5 . Suitable choosing of the putters according achievement variables such as bodily physical specifics and arm length and total body length in shut – putt . 6 . To worker and coaching in sports take care about quantity instruction power in hit phase and fewness of absorb time prospects destiny to conclude this make in push phase . 7. Making research quarrel on biggest samples and highest level to became the result publicly and inclusive .
