The role of biokinetics is crucial in any aspect of the movement while human body or its parts are involved. I do not want to go into such details as the work of nerves, muscles, ligaments or flexors mainly because my medical knowledge is not sufficient as well as I am of the opinion that it is really not necessary when one needs to see The Big Picture. In fact, it would darken the picture.
Nevertheless, this essay would be completely useless if there is no medical knowledge involved. Pure physics describes simple machines precisely well, however, a human body is an extremely complex "machine". That is why, I spent a lot of time studying such aspects of anatomy as e.g. kinesiology, arthrology, ophtalmology, orthopaedics, etc. and exchanging many thoughts with specialists. The language I use in the articles is a simple one so that the "big picture" is not unnecessarily darkened again.
First, we have to be aware what in our bodies is responsible for movements - there are three main parts of it:
- human skeleton (which is a passive base);
- ligaments (which are the links between the passive base and active elements);
- muscles (which are active motoric elements).
The above parts create a very complicated system based on levers thanks to that we, humans, are able to change the location of the whole body, change the location of various body parts in relation to others, maintain the stability and react with counterbalancing.
In short, our bodies are equipped with main body (thorax+abdomen) and distal parts of the body (neck+head, arms, legs). The fact that there are distal parts in our body is crucial for our movability, yet it brings timing issues into consideration. If, theoretically, human body consists of only main body, there would be no possibility of independent movements of any parts of the body - imagine e.g. a turning regular polyhedron.
However, when such a regular polyhedron is equipped with distal parts, the whole situation changes diametrally. Moreover, we are equipped with distal parts that, additionally, are equipped with joints (that enable considerably bigger variety of movement directions). More possible directions of movement mean more problems in coordination of the whole body movement, especailly taking into account that all distal parts tend to act independently (due to the specifics of the nervous system and our brain activity). We must not also forget that the role of two of the distal parts of our bodies, i.e. legs, is mainly to support our body and allowing to be in a vertical position.
Golf swing motion is an example of a relatively simple motion since the movements of all distal parts of our bodies can be subdued to the main body movement since the directional orientation of all the motions are practicaly the same. The only one big change of orientation may happen during transition when the upper body motion is different to the lower body one, however, let us not deal with it now. The whole trick is to subdue them in such a way that allows us to generate power to a satisfactory and necessary degree what is sort of a vicious circle as it appears.
In next subarticles of this article category, I will try to describe the biokinetic rules of all three distal sections of our bodies in a golf swing, mainly taking into account the minimalization of the timing issues that influences the coordination of the whole movement as well as describing alongsidely similarities and differences between model ballstrikers.
Less timing issues = less small thoughts and concepts = more coordinated motion = more repeatability and consistency - this is the motto of all the category of my articles belonging to this publication.
