التحليل البيوميكانيكي و النشاط الكهربي للعضلات للتمرينات الخاصة لتكنيك الخطوة في سباق 100 متر عدو

الملخص EN

The research aims to analyze the biomechanical and electrical activity of the muscles for the special exercises of the step technique where the special exercises of the enemy technique is important because it is designed based on the characteristics of the enemy step and divided into moments touching the ground and the propulsion and flight and return These moments can determine the quality of the step if the enemy was formed The study sample of a high-level runner in the 200,100 meter race (age 25.00 ± 0.89 years, weight 80.50 ± 0.84 kg, length 183.67 ± 1.21 cm) the athlete performed two exercises for the enemy's 5 drill exercises and step, Or myon simply wireless analysis of Swedish muscle to measure the contribution of electrical activity of the muscles and the measure of strength (Bertec 4060-10) to measure the momentum of the man's ascension and maximum The results of the study were identical to the one-legged exercise with weighted men.

The results of the study were based on the analysis of the biomechanical analysis and analysis (9.02 SIMI 3D motion analyzes) for the extraction of kinetic variables for the center of the body weight.

The other in front of the enemy step in terms of motor structure and the corners of the upper and lower limbs followed by the exercise of the jump in the sole of the feet associated with the step of the enemy in terms of increased production of vertical strength and stability of the trunk and the triangular extension of the joints of the pelvis and knee And the foot and then the jump exercise from the half of the parking was linked to the tactics of the enemy step in terms of production of horizontal and vertical force and angles of free man of the moment of payment and the angle of the elbow joint.

The results of this research can be used in the selection of exercises that are used to develop the technique of the step of the enemy to the stage of the maximum speed accurately for all phases Or mastering specific stages.
