ٍSome Kinematic variables of running –approach and its relation with the Level of Achievemeub in Long-jump

Abstract:
The researcher aims at studying the values of the Kinematic variables in connection with the approach run , such as its distance , duration ,speed rate ,momentum ,motion energy , and the number of steps in it , the work also aims to study the relationship of the values of the Kinematic variables with the level of achievement of the sample in this study .
The descriptive methods has been adapted within a survey approach .
Fifty six first year students from the college of physical education in the university of Mosul constituted the sample of the study . Each student was given three attempts long jump , and the attempt which exhibited best performance was depicted for study and analysis . The relevant Kinematic variables were selected by a specialized team prepared for the purpose . the results were calculated using the statistical methods of the mathematical mean . The "standard deviation" and the simple correlation coefficient (Paerson) .
The researcher has found out that the subjects performance revealed no significant correlation relationship between the level of achievement and the distance of the approach run , or the number of steps in it . This has been due to the shortness of the approach run and the long duration of the distance . However , an significant correlation relationship has been found between the level of achievement , and the rate of speed in the approach run , its momentum and the motion energy of the sample . Accordingly , a recommendation has been put forward by the researcher that during giving instructions , the teachers should emphasize the technical aspects that contribute to the level of achievement , such as the approach run , its duration , and the number of steps in it .
