This mechanical element can accelerate his foot when kicking the ground, nevertheless, the source of its rotation keep always constant speed.
Consequently, I can see that this mechanism show the best ideal more than the actual performance of the athlete. I think it is the will of the universe. if it is true, a similar mechanism might be applied to all body parts. said so, I also succeed to apply same principle of the mechanism to the body and arms.
Also to other animals. thereafter, I realized examples of biomechanical locomotions of fishes, 4 legged animals, birds, insects, on the basis of the same theorem.
I have found that the simplest comprehensive mechanism has the possibility of unlimited application.
