Abstract: Freestyle swimming activities differ from other sports in their physical and mental requirements for what they need in distinct preparation during the learning of the skill from a mechanical point of view and the requirements for mental and kinetic compatibility as well as the stages that these movements go through in terms of their sequence and the difficulty of the growing movement in them. In the various stages of learning the skill, which is described as a closed skill. Freestyle swimming skills are among the closed mathematical skills that require training and mental preparation with infinite accuracy, indicating that "the complete mental perception of the skill as it leads the athlete to success with his movements and gives him the ability to discover the new technique and the ability to match the movement, since like people who have a sense of movement are able to accomplish skills." Others cannot accomplish it (Osama Kamel 2: 57).
