Development of physical qualities and improvement of the level of functional possibilities of runners

Augmentation of speed of muscles' contraction and improvement of coordination processes assure considerable level of muscular contraction during physical load. Improvement of accidental muscular tension and relaxation is necessary in augmentation of power and quickness of muscular contraction with the purpose of effective augmentation of sports results in motion actions. It is necessary to use the systematic control of degree of accidental tension and it is necessary to estimate the degree of muscle' relaxation during development of physical qualities of young and adult sportsmen.
