أثر الجهد البدني اللاهوائي في نسبة تركيز حامض اللاكتيك و الطاقة المصروفة لوظائف القلب لدى لاعبي أندية بغداد النخبة بكرة اليد للشباب

الملخص EN

The aim of the research is to identify the effect of the anaerobic physical effort among the individuals of the sample, and the relationship of the effect of the anaerobic physical effort on the ratio of the concentration of lactic acid and the energy spent for cardiac functions on the individuals of the sample, and the researcher used the experimental approach to its suitability to the nature of the research and its requirements, and the research sample was chosen in an intentional way from players of Baghdad clubs Elite handball (8) players, and in order to know the homogeneity of the members of the research sample with the variables of length, age and weight, the researcher used to use the coefficient of torsion that showed the homogeneity of the sample, and concluded that the percentage of lactic acid concentration was different among the members of the experimental sample, and that the sample collectively had a level of fitness Physical exercise is very good for the individuals of the experimental sample, with an increase in the energy index in the index after performing the graduated effort in intensity for varying periods among the members of the experimental sample.

It recommended the necessity of conducting follow-up laboratory tests during the training period and periods, while developing training programs that delay the emergence of lactic acid concentration In the muscles, this saves fatigue, thereby increasing the physical and skill potential of the players, and codified and high-intensity programs programs when the players reach the period of For your preparation.
