The research aimed to prepare axial stability exercises according to the contractile work of the rectus femoral muscles of the young hammer throwers, and to identify the effect of axial stability exercises according to the systolic work of the rectus femoral muscles in the moving balance and the achievement of hammer throw for young players, so that the researcher assumes that there are statistically significant differences between the results of the pre- and post-tests of the experimental and control research groups in the moving balance and the achievement of hammer throwing, and there are statistically significant differences between the results of the tests of the two experimental research groups and dimensional control in moving balance and hammer throwing achievement, The experimental research methodology was adopted by designing the experimental and control groups on a sample that was deliberately selected by a comprehensive inventory method of young players in an event that numbered (10) players representing (100%) of their original community represented by the Electricity Club, who are continuing their training for the sports season (2021-2022), and then they were divided into two experimental and control groups of equal number, and after determining the tests, the researcher prepared axial stability exercises according to the systolic work of the rectus femoral muscles, and experimental at the beginning of each unit and at the beginning of the training unit. It precedes the strength exercises of the arms, and by (20%) of the main part included (3) exercises and repetitions (10-15) repetitions, and from (2-4) groups and the method of interval training of high intensity, and rest periods according to the anaerobic power system of each training unit and at a rate of (2) training units per training week, and for a period of (8) consecutive weeks And strongly from (80-90%) of the moving balance time with resistances that target the different systolic work of the rectus femoral muscles as well as the use of balancing tools, and after the completion of the experimentation, the results of the pre- and post-tests were processed with the (SPSS) system to be the conclusions and applications that the axial stability exercises in different systolic work of the rectus femoral muscles help in improving the moving balance and improving the distance of hammer throw achievement in young players, and they outperform the improvements in their peers who train without them, and it is necessary to observe the rules of Balance when training resistors on both sides of the trunk when targeting training a muscle group (spiral line) around the body.
