Abstract

    The importance of the study was highlighted in the fact that one of the most recent training techniques was training in elastic resistances, which targeted the tensile, elastic and muscular stress of muscle groups during performance through a gradual increase in intensity and ability to resist them by the muscle groups and, consequently, the development of unusual stresses by the muscle groups, which constituted an additional burden to be overcome during performance while maintaining the correct motor path of the duty. The study aimed to identify the effect of flexible resistor exercises on certain abilities The study sample consisted of 8 hoppers representing the elite hoppers under 20 years of age. The study variable was identified as the bio kinetic potential It is distinguished by speed, transition speed, and balance) and the achievement of effectiveness. The exercises were applied with the flexible resistors method over three months by 3 units per week and some completion of them and the use of statistical means for the results of the pre and post tests. The study and the training of flexible resistors contributed to targeting the position of the muscle during performance, The increased tension at this stage thus contributed to the increase in the production of the force and the rapid production of the force, which positively reflected the development of the explosive force, fast force and speed. In addition, the flexible resistor training method was superior to that used by the long jump jumpers under 20 years. The study recommended that reliance should be placed on the flexible resistor training method for the effectiveness of the long jump since it had a positive impact on the development of bio kinetic and achievement capabilities. It was also necessary to emphasize the use and development of modern and various training methods that contribute To improve the bio kinetic potentials of within and thus to improve achievement.
