This research aimed to develop a proposed training program using training by restricting blood flow and knowing its effect on some physical variables and the effectiveness of skill performance for young boxers in Sharkia Governorate. The researchers used the experimental method, and the research sample was chosen by the intentional method of young boxers at the Haya Sports Club in Sharkia Governorate. An officer consisting of (10) boxers, and the researchers used (5) boxers as an exploratory sample from outside the basic research sample and from the same research community to calculate the scientific transactions for the tests under study. Some devices and tools have been used, and the basic research sample has been subjected to the proposed training program for a period of (6) weeks, with 3 training units per week. The extracted data were processed with appropriate statistical treatments, including (the arithmetic mean, standard deviation, skewness coefficient, "T" test to calculate the significance of differences, and the equation for improvement rates). The most important results were: that training by restricting blood flow led to improving the physical variables (strength characterized by speed - performance endurance - muscular endurance), and the effectiveness of the skillful performance of young boxers, members of the research sample of the experimental group, by designing a proposed training program using the method of training by restricting blood flow. the blood . The researchers recommended the need to pay attention to the development of physical capabilities and that training by restricting blood flow be an essential part of the sports preparation programs for young people and adults, and the importance of training related to restricting blood flow with the nature of the practiced sports activity.
