Universal Law of Biomechanics
All human beings have the same basic structure in their anatomy. All arms are built the same way, all legs are built the same way as are our spines etc. Therefore it is logical to conclude that all of our limbs work the exact same way in all movement patterns.
What differentiates each person is their height, length and width. In the late 1400's Leonardo Da Vinci proved with his Vitruvian man drawing that we had geometric proportion to us. We can therefore conclude that anything with geometric proportion to it only works maximally at specific joint angles. The human body to produce power has to align the spine and the limbs at specific 90 degree angles. This is universal to producing force in any sport with any limb. Running, jumping, hitting, throwing and kicking all require the same alignment and specific pathway for the limbs to follow. In other words whether you are throwing a football or baseball your arm can only work overhead in conjunction with your body to produce maximal force in one optimal way regardless of what your hand is holding. We all have the same basic arm design so how it works maximally is universal to all of us. What happens in sports is people teach based upon what they think they see someone is doing instead of studying human anatomy and applying how those joints work to the specific sport.
An easy modern day example is the popular story of Tim Tebow. He is what we call an arm dragger and his throwing mechanics are easily fixable especially with his work ethic. Throwing a football is a learned behavior and is was obviously taught improperly without the understanding of how the humerus bone has to properly rotate within the shoulder joint. Poor throwing mechanics will limit his career and are an example of the importance of learning the correct mechanics first as they become increasingly difficult to change the longer it is left unchanged.
All movement patterns are controlled by the Nervous System. The correct biomechanics neural pattern has to be repeatedly patterned correctly in order to become a conditioned reflex. The myelin sheath that surrounds the nerves will actually thicken over time providing a more efficient pathway for the nervous system. This is imperative in perfecting biomechanics which is a necessity for elite sports performance.
It has been an accident that I figured all of this out and is a result of having to fix countless athletes, performing myself and hours upon hours of watching videotape of elite athletes. Suddenly it was easy to see that there was an underlying Universal Law of Human Biomechanics that applies to all sports and it always involves 90 degree angles.
