| Abstract | ||
| The international advanced players kick the straight ground kick due to difficult to fend off , because it gets out line with straight line and critical height which will be on the level of the net , then starts to be down to ground with low level which cause obstacle for competitor to fend off , besides to high speed which mostly distinguished this kind of kick , the research's problem found that the number of players by trainers was not complete during execution the task of training units whereas the care focusing on specific variables centers without taking consideration for some variables which have an important impact between then as independent variables positively effects in accurate and strong performance skills and especially skills of the ground straight kick and what have as relations of connection whether direct or indirect , and continuity and given objective and scientific judgments by build a movement biomechanical movement and causality effect with comparison and inclusion the causality doctrine (result) in the connection relation and which multiply direction the study's aims included to identify the direct and indirect relation biomechanical variables with front kick skills the build sample of causality of most important variables for the biomechanical to straight ground front kick , the researcher has deal with theoretical studies to biomechanical and movement analysis in sport field , also she deal with the straight front ground kick and the process in which perform way for this kick and previous studies , the sample included the third stage students of AL-Qadisiya University , amounting (44) students , getting the sample by intentional method by depending on the teacher in order achieving the goal whereas the skills of the straight front kick if difficult skills and never improve its performance except for specific number of stage's students , which obliged the researcher of this kind of sample , the test and filming done during the morning at physical education college stadium by tennis at AL-Qadisiya University , the study has showed the decrease the distance between feet improve performance skill and height point variable exceed the other medium variables to transfer the most impact of direct effects and the medium variables meant which is between transfer the impact between two variables of first variable to 3rd variable as result the medium variable in this expression represent the 2nd variable , it is possible to desirable the indirect impact which happen with 3rd variable , the researcher recommends with necessity to design training system by the causality sample to improve performance of the kick the most important variables achieved higher size effect through concentrate on them in training process . | ||
