The effect of dynamic lactic exercises on the concentration of lactic acid and the development of the skill of receiving from movement and then passing for juniors football players

Abstract

            The purpose of this paper is to preparing dynamic lactic exercises and knowing the extent of their impact on the concentration of lactic acid in the blood after stress and the development of the complex offensive skill of receiving from movement and then passing for juniors football players, during which the researchers used the experimental approach (and by designing two equal groups with pre-and post-tests) for its suitability to the nature of the problem and access to achieving goals search. After the research community identified the emerging football players in the Specialized School for the Care of Sports Talent in Babylon for the sports season (2020-2021), whose ages ranged from (14-16) years, and they numbered (35) players, and after excluding the goalkeeper, a sample of them was selected consisting of (24) players using the simple random method, and dividing them for the purposes of the research experiment randomly by (12) players for each of the experimental (dynamic lactic) and control groups. After completing the process of testing and measuring the research variables for the pre and post-tests, and after applying the research experiment, the results were reached as follows: The exercises of the experimental group (dynamic lactic) were more effective in improving the concentration of lactic acid and the skill of receiving from movement and then passing for juniors football players compared to the exercises of (the control group).Then the researchers recommended: Football coaches should use appropriate exercises that effectively develop the players' special abilities and thus improve the level of skill performance and Paying attention to and focusing on measuring physiological variables such as pulse, level of lactic acid concentration and others during the performance of exercises for all age groups for the purpose of legalizing exercises and knowing the extent of their impact on players.
