| Abstract: | A Dynamic analysis of the motion in walking race is given in thepresent paper by using the multibody model of a human body.The integralin the analytical form can be found from the dynamical differential equa-tions.It is shown from the results of calculation that,in order to raisethe speed of walking,to avoid foul take-off and to reduce the impact onthe treating foot,it is necessary for the sportsman to maintain a constantheight of his mass center and make the sole of swing leg close to theground.The results of analysis provide a theoretical basis for the trainingof sportsmen in walking race. |
