Innovative device to control the body tilt angle during the stage of increasing speed and its impact on the number of steps and completion of 100 meters sprint

The work angles of muscles and body parts control most sports events, including the events of the race activity, and the effectiveness of the sprint 100 meters of multi-stage events that require linking them provide a sufficient amount of compatibility for fitness elements under the conditions of economy and the provision of appropriate energy To move to the next stage with a particular fluidity and speed, here comes the importance of the angle of the tilt of the body and the gradient in raising it within the stage of increasing speed within the distance of 35 meters from the beginning, and because of its characteristics in influencing achievement and also in reducing the external and internal effects which decreasing from runner speed that will ration the open body tilt angle is the focus of work at the increasing speed stage. The importance of the research is manifested in the creation of a device that works to open the angle of the tilt of the body and gradually to the desired angle, which will provide a regulated performance within the stage of increasing speed the researcher used the experimental method in the style of the group in the style of the one group by pre and post measurements, but the research community has included the research community players elected Al-Qadisiyah University is in the 100-meter sprint and has 6 runners, as the training curriculum was applied using the device to all of them. The training curriculum will be from (24) training units and was over the duration of (8) weeks and by (3) and training unit per week and distributed on the days (Sunday, Tuesday, Thursday) where the application of the training curriculum was initiated on the sample of the study and they are the runners of the 100 meters sprint. The researcher used multiple statistical methods to process the results, including the T test for interrelated samples, as well as the regression equation, as well as the use of appropriate statistics for pre and post tests.
