Research on the Distribution Characteristics of Plantar Pressure of Cha-Cha-Cha

摘要

This paper makes measurement and analysis on force distribution of foot for several outstanding cha cha cha dancers by using the Footscan insole 2.39 system, discusses the distribution characteristics of plantar pressure in four aspects about the F average, F max,% Peak and% Contact. The result shows that the forepaws are under high pressure when doing cha cha cha dance, especially the big toe and the first metatarsales area, and the heel parts are under small force. In the fifth step, male athletes reach maximum pressure in right foot inside metatarsal, the left one reach a maximum when the focus back in the second step. Female athletes reach maximum pressure in booth feet in the first step. In cha cha cha square step, the forepaws hardly leave the ground, especially the foot inside.
