Abstract EN

Research in the field of physical and sports sciences has become a feature of these countries to achieve high achievements through the heroism industry by developing their physical, skill and plan level.

This development in sports performance has taken a great part by focusing on the specialized level of athletes in sports, The specialized process in which to improve the level of physiological aspects (functional through the development of the work of the circulatory and respiratory).

The measurement of some physiological and biochemical variables that occur in the body as a result of the practice of tennis and the extent of functional adjustment that results from the specialized training of the game.

These physiological and biochemical variables (number of heart beats, blood O2, LDH, AST, PH, and sodium ions) The changes that will occur will help the training process to understand the basis of these variables and then to identify the physical fitness of each player through which it is possible to identify the training process and develop the physical level of players in tennis because of those changes from the The problem of research is the following question: (Does the physical physical exertion affect some physiological and biochemical variables in tennis players? ).

The most important conclusions were the high levels of heart rate, LDH and AST after physical exertion compared with resting periods, lower levels of O2 blood, PH blood and sodium ion in tennis players compared to rest periods.
