The main purpose of this work is to improve Yurchenko's jump on 12-year gymnastics so that performance improves by getting higher scores than those previously obtained in competitions. Applying exercise systems for the development of lower limb force, lower train corbet speed and arm expansion - adapted and modified, in conditions of difficulty or in a easy way, will reduce penalties. Methods of research. The study was conducted on 4 gymnasts of 12 years old during 2 years.Due to the particularities of training at this level, we did not consider it appropriate to set up a control group, analyzing in this regard the progress made by gymnasts in general and individually.The jumps performed in three national official competitions were analyzed, in terms of the time taken during each jump phase, the angles formed during execution, but also on the final and execution notes.The images were processed with an online editing program - https://pixlr.com/express/. The data recorded by the time measurement of the competition's jump phases were achieved with the Hudl Technique Elite program at a video rendering capacity of 60 FPS. During the experiment the subjects were tested in 3 stages Results. The time taken during each jump phase improved on every test, the angles formed during execution also improved so that the jump phases became more accurately that conducted to better execution notes in the third national competition. Conclusions. Operating systems have shown that at least 5 months after the start of the experiment, it has been beneficial to improve the final note. This improvement seems to be due to the leap corresponding to Flight II.
