Effect of the Dynamic Lactate Style to Developing Defensive and Offensive Performance Endurance for Handball Players Under 19 Years.

The importance of the research lies in the application of a modern training method for training handball in order to raise the player’s physiological and skill efficiency throughout the game and maintain a constant level of performance and resistance to fatigue, especially the ability to perform with the presence of lactic acid and benefit from it after converting it to energy. The research aims: To identify the effect of the dynamic lactate method on developing the tolerance for defensive and offensive performance of handball players under 19 years of age. The researchers used the experimental design with two groups of experimental and control, with pre and post- test, for its suitability to the nature of the problem. The researcher identified the research community with handball players in the Karbala Sports Club for the youth category of under 19 years of age for the 2020-2021 training season, whose number is (16) players. By (7) players for each group. As for the most important conclusions, the results of this study demonstrated the effectiveness of the dynamic lactate method in developing endurance of defensive and offensive performance with handball among the players of the research sample, while the recommendations were, the researchers recommended that the dynamic lactate method should be used in the training units..
