Some kinematic variables of the rising and flying phases and it relation with the level of achievement in long jump
Abstract
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
