The effect of Hypoxic exercises in and out of the water on some physical and physiological variables and the Record level of middle distance swimmers

The research aims to identify “The effect of Hypoxic exercises in and out of the water on some physical and physiological variables and the Record level of middle distance swimmers” The experimental method was used in the experimental design of a group for two groups, one experimental and the other a control. consistent with the nature of the research,The research sample was also chosen by the intentional method from 400-meter freestyle swimmers at Al-Hiwar Sports Club in Dakahlia Governorate under the age of 15, whose names are registered with the Egyptian Swimming Federation and who participated in competitions for the training season 2020/2021. The sample size was (20) swimmers, where they were divided equally in a random manner into two groups The experimental group reached (10) 400m freestyle swimmers, who used the breathing control training program in and out of the water, The control group reached (10) 400m freestyle swimmers, which used the traditional program (natural breathing),The most important results were that the proposed program using breathing control exercises applied to the experimental group has a significant effect between the tribal and remote measurements in favor of the dimensional measurements in the physical and physiological abilities and the digital level of the 400m freestyle swimmer, and there is an improvement ratio between the tribal and remote measurements of the experimental group in favor of the dimensional measurements as shown From the averages of the measurement.
