This research aimed: To identify the design and implementation of a training program using simultaneous training (muscle strength and endurance) with blood flow restriction and to know its effect on some health variables (physical, physical, physiological) and the level of skillful performance of squash players. The researchers used the experimental approach due to its suitability for the type and nature of this research through the experimental design using the pre and post measurements of two experimental groups. Restriction of blood flow), and (12) players from Black Ball Sports Club as a second experimental group (simultaneous training), in addition to the sample of survey studies from Al Shams Sports Club, numbering (8) players, so that the total sample is (32) players, and the researchers used measurements Health and skill performance level as a means of data collection. The extracted data were processed with appropriate statistical treatments, including the arithmetic mean, standard deviation, median, skewness coefficient, significance of differences test (T), simple correlation coefficient (Pearson), and improvement rates. Among the most important results: The proposed simultaneous training program by restricting blood flow had a positive effect on the health variables under study, physical (upper circumference, thigh circumference, muscle mass weight), physical (flexibility, agility, arm and leg strength endurance, aerobic endurance), and physiological ( Pulse at rest and after exertion, cardiac impulse, pulmonary ventilation, vital capacity, maximum oxygen consumption) for squash players, the research sample. Improvement of health variables (physical, physical, and physiological) as a result of simultaneous training by restricting blood flow led to a significant improvement in the skillful performance of squash players. And noticeable.
