As we know the effect of lactic acid concentration on the achievement of middle-distance runners by investing it in training units in order to develop some physiological variables and the achievement of middle-distance runners. Middle-distance running activities depend on the endurance trait to increase aerobic and anaerobic capacities, in terms of upgrading these capacities which improves the work of the heart and lungs (circulatory system) as well as metabolic processes and converting food into energy in the muscles. Since the special endurance trait (speed endurance - strength endurance) and the rate of lactic acid accumulation in the muscles and blood are among the most important variables affecting the achievement of middle-distance running, and relying on these variables puts the coach and athlete in a safe zone whether during training or racing, the researcher decided to study the effect of lactic acid concentration and the level of achievement of middle-distance runners.
LA is a paradoxical bye product of physical activity. Produced when a strenuous effort is produced, continuous effort lasting 45 seconds at least where it reaches its maximum level of concentration. At this level the muscle fibers are blocked and stop producing force. It takes to lower the level of concentration of this biological product. Training must help athletes get used to a high level of LA production. It is not only a physical challenge but a psychological too.
