Through the theoretical analysis of the technique of pressing down the supporting foot backward to hold on to ground in dash,this paper thinks that the technique is the major factor that raises former thigh pendulum effect and promotes the fast reach of human body pendulum effect,so puts forward the method of training in order to reach the purpose of raising sport record.

This paper,analyse the right side of instep shooting according to the sport biomechanics principle,run-up,support that foot stand location,play football swing,foot touch ball,after playing football movement before up to whole technological movement structure.

This paper introduces the parametric design of engine bearer foot with different structure.
