The research aims at recognizing the impacts of the skillful exercise according to sensory preference to develop times reaction (acoustic and optical) to same kinds of defense skill. Furthermore, the research aims at recognizing the priority of such exercise according to sensory preference and the approach adopted to develop the speed of the reaction (acoustic and optical) to same kind of defense skill. The scholar utilizes the experimental approach by devising two equivalent groups, which have pretest and post-test the sample of the research contains (22) players of education - Al-Karkh first and third in percentage 48-89% out of the original community. The scholar has carried out the pretests on (Tuesday 29-10-2019) to the experimental group. On (Wednesday 30-10-2019) the scholar has carried out the pretest to group control.
