Looking at the human body, in particular the head, it’s a wonder we exist at all. Our operations center is basically held in place by small bones and strong neck muscles. The human brain weighs between 3.5-5.5kg or 8-12lbs which does not seem like much until you find a 10lb medicine ball and try to balance it on a pole. Once balanced then strike the ball and then you will be amazed at how our body handles extreme forces. Even more convincing would be hitting the pole or lower and look what happens to the ball, our body is simply amazing.
In order to control your skull – in effect your brain – the neck muscles must be good at detecting even the slightest movements and be able to activate in an instant to compensate for sudden trauma to the head or body. It would stand to reason that increasing the strength of your neck would also help with lowering transitional forces to the head.
There is one little caveat with this example, the brain itself. On average the brain weighs 1.5kg or 3.5-4lbs, which makes up the majority of the weight in our head an it is not attached to anything. That is the crux of the problem; a free-floating organ – our most important – that is susceptible to forces anywhere on the body. This is why helmets cannot claim, nor do they, prevent concussions and it is why even with the strongest neck an unanticipated hit (when neck muscles are not tensed or engaged) can and will result in acceleration of the head. Translated that means high potential for concussion.
