With the advent of the third millennium, which is characterized by a technological revolution in all fields of life, which has also affected the sports field and the development of modern systems and techniques through scientific research to identify the abilities of the players which are in physical, physiological and skill capabilities and the distinctive players in any field of competitive activities at the national level And the world is characterized by the wealth of developed countries in the type of competitive activity and become these distinctive players are the example and model to be guided as a database in the selection of young people according to the specifications of physical standards and the performance of skilled heroes of the Al-Mumtazin. The water ball is one of the sports activities that differ from the rest of the sports activities. It requires the mastery of swimming methods and the superiority of the performance level, which makes the work of the muscle user of a special quality and nature, resulting from the release of energy in muscle fibers, and this energy varies in nature and rate from time to time And from one distance to another according to the skillful motor responses of the water polo player. Studies indicate that the percentage of the maximum consumption of oxygen for water polo players increases by 6 to 20% from swimmers and includes air work performance of 50 to 60% and the proportion of 30 to 35% of the anaerobic action and 10 to 15% of the system of rapid energy and average The player’s pulse during the game was 150 n / s at 91.8%. Since the purpose of identifying physiological changes is to attempt to describe and interpret these changes in order to reach the physical and physiological level, Maglischo (1993) pointed to the physiological changes resulting from the use of aerobic training levels, Increase the tolerance of aerobic capacity development, improve the speed of muscle contraction of both fast and slow fibers, improve metabolism of fat, speed of elimination of lactic acid accumulating in muscles, while the physiological changes resulting from the use of For the anaerobic training of lactic acid, lactate production, ability to increase anaerobic capacity, increase the capacity of vital organizations, increase lactic acid production, and increase muscle capacity. Water ball requires one of the collective games practiced in the water medium for players with high abilities and characteristics, whether physical, physiological and moral, in proportion to the modern trends of training in this game. Through the work of the researcher in the field of water polo training in addition to the knowledge of various scientific sources, he noted that the use of aerobic and aerobic physical loads is in a random manner, among most trainers of water polo in a manner inconsistent with the nature of the training stages, In addition to not relying on the results of physiological measurements in the regulation of physical loads, which helps to raise the physical and physiological level of water polo players.
