The effectiveness of crossfit training in some muscular strengths and the achievement of 100 meters freestyle swimming

Abstract

The research aims to prepare crossfit exercises for the sample members, to identify the differences between the pre and post tests in some aspects of muscular strength and the completion of 100 meters free swimming for the control and experimental group, to identify the differences between the post tests in some aspects of muscular strength and the completion of 100 meters free swimming for my groups The experimental and control research, and the two researchers used the experimental method to achieve the objectives of the research, and the research community was deliberately identified from the Dukan Sports Club swimmers, the category of applicants, whose number is (14) swimmers, and (12) of them were selected as a sample for the research.Thus, the sample percentage reached (85.71%) fromthe total community, and the sample was divided into two control and experimental groups randomly by lot, with (7) swimmers for each group, and the duration of the training curriculum was (8) weeks at the rate of (three units) per week, thus the number became The total of the training units is (24) units, and the curriculum vocabulary was applied to the experimental group, and the training curriculum contains two intermediate courses, so that each medium course consists of (4) minor courses (weekly),The researchers used the crossfit method to develop the speed characteristic of the legs and arms, and the endurance of the force for the arms, torso and legs. (arms, abdomen and legs), and that the development in some aspects of muscular strength had an effective role in developing the level of completion of 100 meters free swimming, the experimental group outperformed the control group in all the variables studied
