The performance of rotation is one of the important skills and has importance in the achievement in the types of swimmers and is characterized by rotation in breaststroke with kinetic and technical performance that enters into the daily training of swimmers, because the correct rotation accomplished by the player earns him greater progress than his peers in fractions of a second and because swimming is one of the digital games, so it is important to follow up and identify all the details of performance from the moment of beginning to the end and highlights the importance of research in identifying the maximum force to push the two legs in the skill of rotation The axial and its relationship to the achievement of swimming 100 m breaststroke. The research problem revolves around that when rotating in the race, the work of the two men has the largest role in the forces that shed on the wall of the swimming pool and what has to do with the forces that shed on the results of that force inside the water after rotation and flow inside the water for the largest possible distance and in the shortest possible time Where the problem of research lies in identifying that maximum force by the two men outside and inside the water by rotation and to identify their relationship to the achievement of swimming 100 breaststroke and in order to emphasize the interest in the training of the maximum forces of the two legs in swimmers, especially when rotating for swimmers. The objectives of the research was to prepare a test to measure the force of the axial rotation entered the water and to identify the maximum strength of the two men inside the water either the research approach used the researcher descriptive approach with correlation relations either the research sample was the players of the youth team swimming and their number (6 players) and they represent 60% of the original community of 11 swimmers and the results indicate a relationship of strength for the axial rotation and the completion of swimming 100 meters breaststroke.
