摘要：Kinematics and dynamic descriptions at run of sportsmen are certain. Made recommendation for adjustment of motions and improvement of technique of motions. A videosurvey at run is conducted on short and middle distances. Dynamic descriptions are considered: force of friction, force of pushing away, reaction of support on a direct area and turn. It is set that maximal values of force of friction on a direct area were 90 N, normal reaction of support - 595 N. Maximal values of force of friction on a turn were 95 N, normal reaction of support - 610 N. Maximal a value of force of pushing away on a direct area was 600 N, on a turn - 619 N.
