Abstract

The purpose of the present work is to justify the use of specialized methods of exercises in sprinters training. These exercises use asymmetric force actions in high-speed running by means of weighting down on one leg. The change of the local force actions, by adding extra weight to the lower limbs, radically alters biomechanism links in creation of forces in the body of an athlete in take-off in the cyclic exercises with maximum intensity. In this case, the capacity of non-core muscles increases within the motions which are consistent with the functioning of the main parts of the body. And the available intensity of the selected exercises generally increases as well. And that, ultimately, leads to a higher training effect. The basic difference from the classic examples of the weights on both legs is that the use of asymmetric force action allows sportsmen to exercise with more frequent motions. Speed regulation and speed barrier can be avoided by using recurrence of high-speed racing with asymmetric power in the training process impacts in the form of weights on one leg. Due to the difficult conditions, the functional ability of the athlete cannot fully adapt to this exercise. However, it leads to improvement of special strength training in natural conditions of doing a competitive exercise. The given technique of using an asymmetric power influence in the race makes it possible to change the ratio of length and frequency of the running step by intensifying the force component in the whole structure of movements at the same speed of movement. In general, the proposed method will provide the increase in athletic performance due to the simultaneous increase of both rates in speed running, both the frequency and stride length.
