تدريبات القدرة العضلية وفقا لمؤشر الأداء المثالي المطلق على بعض المؤشرات الكينماتيكية لخطوة الحاجز في سباق 110م حواجز فئة دون 20 سنة

الملخص EN

One of the races that relies heavily on mechanical performance control is the 110m hurdles competition, as the performance distance and distance parts impose on working with steady, balanced steps and with a fast ability character, and here enters the important need for biomechanics to work equally with sports training by studying the angles of olute perfect performance And the heights of the center of gravity of the runner (before - above - after), hence the importance of the study by knowing the muscles that work in the main part of the performance and working to put the ability exercises for them within the real performance ranges, which gives the study importance by searching for and improving movement particles.

The research problem was identified and built by observing the exercises of the study sample, noting the lack of speed in the transfer of force at the moment of payment before the barrier, which causes successively a decrease in the biomechanical indicators for passing the barrier, and this increases and increases the crossing of the barrier and thus an increase in the total time of the competition, as the researcher used the approach Experimental design with one group with a pre and post test, the research community consisted of runners of 110 m barriers from the Sports Talent Care Center in Baghdad under 20 years of age and mind Their number is 4 runners if the research sample represented the community by 100% , and the researcher used exercises according to the olute ideal performance angles for the research sample and the purpose of which is to shed the outputs of force on the muscle groups working in several angles, which resulted in an improvement in the mechanical performance of the runners.

The researcher concluded that the specialized muscular ability training according to The olute perfect performance angles have contributed to improving the level of biokinetic variables specific to the barrier step because they have an impact on targeting specialized muscle groups to pass.

The barrier to serve the next run.
