【 摘 要 】

Abstract
The researcher aims at studying the values of some Kinematic variables such as the speed vector of the take –off phase , the momentary initial speed vector of the flying phase , and the angle of flying in long jump . It also aims at studying the relationship between the values of some of the Kinematic variables , and the level of achievement of the sample in the study .
The survey method has been employed within a descriptive approach . Six long – jump athletes participating in the advanced national club Championship constituted the sample of the study . Video – filming and film analysis have been used as means of data colecting. The statistical methods of the mathematical mean , the standard deviation, and the simple correlation coefficient (Pierson) have been employed to arrive at the result .
The researcher has arrived at the conclusion that there is abstract relationship holding between the speed vector of the rising phase , the momentary initial speed vector of the flying phase , and the level of achievement (which proved to be low in the subjects ) .
In this connection , the researchers recommended the use video filming and analysis in carrying out tests in order to find-out precisely the areas of errors , so as to overcome them and arrive at a better level of achievement
