The threshold of maximum aerobic capacity and the percentage of lactic acid concentration in the blood as an indicator for evaluating the form in the achievement of running 800 meters

Abstract

The importance of the research appeared in identifying the effectiveness of the training programs prepared by the coaches to know the sports form for each player, whether in the preparation stage or the cometition stage in the event of running 800 meters. And physiological and parts of the race and achievement due to the fluctuation of the level of achievement for a long time compared to the international level reached by the global youth with a time of (1.45.00) seconds, the study aimed to evaluate the sports form through the threshold of maximum aerobic capacity and the percentage of lactic acid concentration in the blood and the level of running 800 meters in addition to the time it takes between the parts of the race, as the researchers used the analytical descriptive approach and the study of the correlations for their suitability and the nature of the research problem on a sample of 800-meter running runners for young people who numbered (5) players who were chosen in the deliberate way after the homogenization of the sample was carried out in variables (variables). The study) Through the results, the researchers concluded that the sample’s random speed rate increased in the first part of the race in a way that was not commensurate with their physical abilities or capabilities, which negatively affected their speed in the rest of the race distance, and the speed rate decreased significantly in the last (400) meters of the race. Comparison with the world-class method, and through the conclusions, the researchers recommend the need to pay attention to developing the ability to control the rate of speed for parts of the race distance by developing the ability of the runners to maintain their speed between the first and second half, the need to pay attention to the development of physical characteristics in general and the characteristic of special endurance in particular (speed endurance - Endurance of strength (in the event of running (400-1500) meters.
