The authors applied CAD/CAM technology to podiatry and developed a foot support design and manufacture system which can input and process sole data, construct, balance and smooth 3D foot support model according to remedial rules,and generate rapid prototyping file and tool paths for milling.

The one-leg stance duration during the one-leg stance were compared.

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.
