General internal construction of human body – the chains
Generally speaking all our bodily movements can be divided into two categories:
the passive movements which caused by external powers. The samples can be the gravitation power, the impulses caused by external objects or partners and so on.
the active movements caused by human muscles. These movements can be walking, running, jumping, turnings, fallings, holdings, gripping, punching, kicking and myriads of other activities.
The movements of human body are based generally speaking on the the impulses which the body had perform prior to them or still performing, using them as platform.
There no differences between passive and active movements from mechanical point of view if the passive movement is under our control. The only difference is that an active movements are initiated by our will contrary to the passives ones.
For example our punch is based on the impulses from our elbows – shoulders – back –waist – knees- feet. The feet’s impulses are based on the impulse of the Earth.
Some our movements are based on the impulse of the Earth, but many depend on the impulses of the parts of our bodies. This is why in many texts appears that the kicking based on the chest movements. The truth is that the chest impulse in it’s turn was originated on the impulse based on Earth.
What I have described here I call chains in the human body. These chains apply our bodily parts fully connected, each after another with some delay. This is a very fundamental law in ISAI.
