The aim of study to identify the effect of lactic capacity and lactate resistance exercises on the development of speed reserve variables, some vital regulators, and level of lactate concentration, and the completion of 800m elite, to identify the preference effect of the three research groups in the studied research variables.
The researcher used experimental design with equal groups (three experimental groups), with two pre and posttests, and the research community consisted of runners in the central Euphrates governorates (Karbala, Babel, Najaf, Diwaniyah) and the capital, Baghdad, for the 800m competition, the category of applicants, whose number is 15 runners, and they represent research sample at a rate of 100%, the sample was randomly divided into three experimental groups, each group includes five runners, and biochemical regulators were selected for the study (bicarbonate, carbonic acid, hemoglobin) and were measured after the achievement test, 30-minute run time test was used to measure the lactate threshold. As for measuring speed reserve and level of lactate concentration, they were measured after achievement test.
The most important conclusions reached by the researcher: the exercises prepared by the researcher contributed greatly to development of ability of vital organizations in the body through; Increasing the strength of hydrogen ion liberated as a result of accumulation of lactic acid / lactate and the decrease in the concentration of bicarbonate (-HCO3) after the effort, the improvement of the ability of the body and muscles to bear the pain resulting from the accumulation of lactate by increasing the level of lactate concentration after the achievement test, and the exercises contributed to development of a reserve index Speed and rate of lactate threshold velocity, which in turn was reflected in the improvement of achievement
