世界上多数动物都是四脚支撑。四脚支撑跑得快,捕猎有劲,虚实变换灵活(参见图1、图2、图3)。人类直立行走足由四脚爬行进化来的。万物有一进化,就有一退化。所以人的跑跳、捕猎的本事退化多了。人脚的足弓还保留有一点点四脚的影子;人类的跑跳,实际上是脚攀支撑,落地后则是脚跟支撑,支撑变换的时间很短暂,所以人们不太留意。武学是仿生学,武学修练四脚支撑,左右脚掌和脚跟 Most animals in the world have four-legged support. Four-legged support ran fast, hunting powerful, flexible and actual transformation (see Figure 1, Figure 2, Figure 3). Human upright foot crawling evolved from the four feet. Everything has an evolution, there is a degradation. So people run jumping, hunting ability more degradation. Human foot arch also retains a little shadow of the four legs; human run jump, in fact, foot climbing support, heel support after landing, support transformation is very short, so people do not pay attention. Martial arts is bionics, martial arts practice four-legged support, soles and soles
