Abstract: In this study, the researcher sought to develop the work of the two men in swimming 50 m butterfly for youth through the use of rubber girdles that impede the blood flow of the legs in low-intensity resistance exercises, by taking advantage of making the muscle environment acidic, which is reflected in the increased stimulation of growth hormone secretion, which plays a key role in Increasing the thickness of the muscle fiber and increasing the muscle strength accompanying it when resting after performing the exercises, which works to bring about the same metabolic and nervous adaptations that high-intensity exercises cause without using this method. Swimming, which lies in the presence of a weakness in the strength of the work of the legs by pushing water during the daily exercises for swimmers, so the researcher decided to go into this study and develop appropriate solutions for it through the use of girdles that impede the flow of blood in the legs in order to benefit from the acidic environment inside the muscles when using this method, which is reflected in the stimulation of growth hormone And thus increasing the strength of the muscles of the legs, which leads to improving the digital level for this distance, as the research sample was chosen from the national team swimmers In swimming 50 m butterfly for young men, who numbered (10), they were divided into two groups, control and experimental, and after that a set of laboratory tests and analyzes were applied to find out the extent to which the benefit of the method of obstructing the blood flow of the two men in achieving better results on the digital level for swimming 50 m butterfly. After completing the experiment, the researcher collected The results and writing down all the numbers that showed the results and then they were processed statistically to find out the final outcome of this study and in the light of what the researcher obtained from the results of this study. Lactic acid as a result of using this training method to obstruct blood flow, which led to the development of the digital level in the 50 m butterfly swimming.
