The term spacial orientation is a psycho-physiologic term used to describe conscious movement of the human body within all planes of motion simultaneously. The most difficult of movements would be to be upside down, back wards, and rotating in fluid motion. Such movements are seen in aerial trapeze, stunt aircraft flying, sky diving, and in all of extreme sport events, as skateboarding
, Inline Rollerblading
, and Motocross
. It is not understood how the human mind can control the body in real-time with such precision in 3-D motion. The amount of mathematical computations to achieve such movements of an amorphous mass as the human body in real-time is astronomical.
An extreme sport
requires a very high degree of skill in the art of spacial orientation.
