Exercises according to the pressure applied to the feet and the length of the step and their impact on reducing the differences in the step of passing the ten hurdles and achieving the effectiveness of running (110 m) hurdles

The aim is to prepare exercises for applying pressure and the length of the step and knowing its effect on the runner of the 110m hurdles event, as well as knowing the size of the impact of the Hijaz step difference at the moment of crossing the ten hurdles and completing it before and after applying the exercises. To achieve this goal, the researcher used the experimental approach with a one-person design (A-B-A). Since the nature of the research requires several attempts, six attempts were applied to form a database. Then he started applying the pre-tests in the Samawah Olympic Stadium, as the player was tested with 6 attempts within three days, with two attempts every day, and then he started applying the exercises prepared for the player for a period of (12) weeks, with (3) training units per week. Thus, the total number of units for the exercises is (36) units using the repetitive training method, with an intensity ranging from (90-100) %. After completing the application of the vocabulary of the prepared curriculum, the researcher proceeded to apply the post-tests, and after obtaining the results, the researcher used the statistical program (SSPSv27.1) to obtain the results, so the researcher concluded that the pressure exercises and the length of the step prepared by the researcher contributed to reducing the differences in the passing step. Among the ten hurdles, which led to regular running speed over a distance of 110m hurdles, and this was reflected positively in improving the time of completion by effectively running (110m) hurdles.
