Zureigat Department of Management and coaching Faculty of Physical Education University of Jordan Abstract This study aimed at identifying the values of some kinematic variables that Affecting of the achievement time for the shuttle run test (4×10 m) in the King Abdullah II Award for Physical Fitness.

In addition, the effect of these different sport surfaces on kinematic variables.

In order to the researchers used Experimental approach on (8) male healthy students at first Zarka education.

The study sample was filmed by using tow video camera (Sony HDR-CX220E) reached speed (50) frame/s.

The study examined stride length, frequency stride, efficiency index.

The study results showed: the average stride length (1.11 m), And it accounts for 76% of the average height of the sample.

As well as the step frequency (36.25).

Moreover, low index of effectiveness.

In addition, the study results showed the best achievement and the highest indicator of effectiveness on the asphalt surface.

The researchers recommends: that necessity the teachers of Physical Education see the results of this study, and replace carpet surface for another type of surfaces that requires it to reduce the standard of this test for the prevention of injuries.
