ESTIMATE THE VALUE OF REDUCING STRENGH ACCORDING TO THE IMPACT FORCE IN SHOOTING IN BASKETBALL WITH DIFFERENT AREAS IN BASKETBALL

ABSTRACT The basketball is one of the most familiar and wide popularity game which require the skills of a lot of movements like running, jumping, throwing, change of pace and feint, and in general the morphology of the skill shooting from rotation indicate the presence of power and reducing the impact effect in maximum knee flexion in order to preparing to jump shoot from rotation. Pivot is more essential players used for shooting because of the positions effective occupied inside the Zone, every player seeking to deliver ball to them in order to make points, and so we see that he is subjected to great pressure requires him great performance with minimal effort and time. The stage maximum knee flexion (reducing strength after impact force) is a section preparatory for the next phase which is to jump and shoot, in this phase we note Newton's second law (F=m.a) that the force is inversely proportional to the time. This research tries to reach to the amounts of forces exerted at the stage of absorption (maximum flexion possible) according to the amounts of the forces of the impact when the performance jumping to shoot the ball after rotation. The (27) successful samples attempt to jumping to shoot the ball after rotation was collected from (9) Pivot players of Premier League clubs Iraqi basketball, from the two regions by (13) attempt from the left of the basket, and (14) attempt from the right of the basket outside from Zone. The data provided from curve force - time through samples test on the platform to measure the force, the correlation between maximum force in impact phase and minim force in reducing effect impact force phase was (r=0.955) tested with (f: p
