الملخص EN

The aim of the research was to try to identify the effect of cross fit exercises on improving some physical variables and the digital level of swimming 50 m and 100 m backstroke for juniors.

the research sample was selected deliberately from the swimming junior, where the number of the sample was (45) juniors.

the researchers used the experimental approach using the one-group experimental design with the pre- and post-measurements for its relevance to the nature and purpose of the research.

the most important results were the proposed training program using cross fit exercises, which led to the improvement of physical variables and the numerical level for the distance of 50 m, 100 m backstroke for juniors and reaching predictive equations for the numerical level of swimming 50 m backstroke, 100 m backstroke in terms of physical variables.

the most important recommendations were to use the proposed training program for cross fit exercises to contribute to improving the physical variables and the digital level of swimming 50 m and 100 m backstroke for juniors.

also similar studies should be conducted on other skills and different age groups for juniors using cross fit exercises, application of the program exercises proposed using cross fit exercises in various sports activities to improve athletes' performance and reach higher levels.
