Popis: According to the data of kinematics and electrical activity of muscles in a state of fatigue when running in a straight line and in a bend there was studied the coordination structure of a running step of twenty short distance runners of different sports qualifications. It is identified that the structure of the running step depends on the level of sports qualification. In comparison with low-skilled runners, when running in a state of fatigue, the athletes of high qualification were distinguished by: more prolonged electrical activity of working muscles; rational changes in in the reciprocal relations of the thigh and lower leg antagonist muscles; a long take-off phase when running in a straight line and in a bend. The results of the study indicate that under the influence of fatigue, the coordination structure of the running step is modified, which is reflected in significant changes in its spatiotemporal parameters and muscle electric activity characteristics.
