الملخص EN

The study was designed to identify the effect of CrossFit training on some physiological variables and the numerical level of 522m freestyle swimmers.

The sample consisted of 82 swimmers who were selected by deliberate method from the research community.

The sample was randomly divided into two equal groups: experimental group 4 swimmers and control group 4 The results of the study showed that the training program using the crossfit training had a positive impact on the development of the digital level of the 522m swimmers.

Rh and improved some of the physiological variables (pulse pressure and the maximum consumption of oxygen and vital capacity), and recommends that researchers need to use "crossfit" exercises to develop and improve the digital level of 522m freestyle swimmers physiological variables
