Abstract
The relevance of this topic is due to the constantly increasing level of sports achievements in the middle distance race, which puts new qualitative requirements to physical training of athletes. Running at 800 m refers to submaximal power exercises, where work is performed mainly in anaerobic power supply conditions. A sufficiently high running speed, which must be for about two minutes, leads to significant changes in the activity of the runner's body systems, putting him in extremely unfavourable conditions of functioning. Maintaining a high running speed in such conditions depends on the ability to perform work in conditions of high oxygen debt and significant accumulation of lactic acid in working muscles and blood, i.e. on special endurance. On this basis, the training of runners on 800 m is primarily related to the development of speed and special endurance, which are in contradictory relations. Supposedly that organization of training of runners on 800 m on the basis of fulfillment of factors limiting growth of their achievements at different levels of skill, will contribute to improvement of quality of training of athletes. We carried out the pedagogical experiment in the experimental group, analyzed the results in comparison with the results of the control group (the experiment was in the athletics section of Tambov SSOR no. 2).
