The search goals are: 1) The values of some kinetic variables are defined as the last three steps of the javelin effect. 2) The relationship between the values of some kinematic variables is defined in the last three steps of the spear. 3) Know the relationship between the values of some kinetic variables and the distance of achievement in the last three steps of throwing the spear. The researchers hypothesized: There are significant differences between the values of some kinematic variables for the last three steps. There are significant differences between the values of some kinetic variables for the last three steps and the distance of achievement. The researchers used the descriptive approach to suit the nature of the research. The sample of the research was chosen in a deliberate manner. The sample consisted of students participating in the championship of the University of Mosul in Al-Salama Square and Field for the year 2011 and obtaining the first five positions in the tournament. (890) meters from the right side of the firing range to shoot the last three steps of the spear. The camera lens height was (1,23) meters above ground level and the velocity of the camera was (25) copies / second. Statistical treatments (mean، standard deviation، and simple correlation coefficient) were used. 1) The effect of the angle of the shoulder joint with the corner of the knee in the third step. 2) Effect of the level of achievement with the knee angle, which is a significant kinetic variable in motor performance. 3) The effect of time, distance and speed of approaches to each other had an impact on the level of achievement. The researchers recommended a set of recommendations: 1)It is necessary to emphasize that the angle of the knee is the man of the moment of touching the ground between (150-180) degree of importance for the transfer of momentum from the trunk to the arm of the target. 2) Confirm that the tilt angle is an approach of or less than the ideal angle for throwing. 3) Emphasize in training to achieve an appropriate starting angle for its importance in achieving a better horizontal distance.
