| Abstract: | The technique of the fore supporting phase (buffer phase) of steady running is one of the focal points of the kinematic and biomcchanicai research of track and field. The present article has discovered, in accordance with the theory of the exercise biomechanical research, the factors, which will have an effect on horizontal speed of total center of gravity of body at the fore supporting phase of steady running, such as. 1. angular velocity of the lead thigh; 2. landing angle; 3. forward horizontal velocity of landing foot at the moment of landing; 4. angular velocity of the upper arm when the arm is swinging forward. |
