Ok, so maybe the title was a little farfetched, but hey, you are here and I hope you enjoy the next few minutes of us understanding the relationship between the structural integrity of the head/neck and strength/muscle growth/power output.
The dictionary defines the term “sensorimotor” as: “of, relating to, or functioning in both sensory and motor aspects of bodily activity” (Merriam-Webster). In layman’s terms, it is how and what we feel and function in relation to the environment around us.
Abnormal sensorimotor skills = below optimal human function.
Additionally, Harrison et al., from Chiropractic BioPhysics, established the ideal neck curve to be in the ballpark of -42 degrees.
As with most things in life, balance and harmony are required to get things done with as little friction as possible. Take for example, the alignment and balance of your vehicle. If one tire has 2 psi less than the others or the CV axle is blown out on one end or one rotor completely worn out, what you will experience is vehicle shaking. Vehicles are not meant to shake. Similarly, the human spine has been mathematically calculated to have 3 curves synced in continuous harmony.
Today, we will focus on the neck curve. When the structure of our neck has been disrupted via poor lifestyle habits and/or minor/major trauma, our sensorimotor skills (see definition above) are compromised. Disruption of the neck curve includes: loss of normal neck curve, military neck, segment(s) either forward or backward in relation to each other, and more. Following disruption of the neck spine, onset of degenerative conditions such as arthritis, disc issues, acute/chronic neck pain, mental fog, dizziness etc. ensues – leading to a lower quality of life.
Now that we understand the how and what of the structural integrity of the neck, let’s dig into the strength/muscle growth/power output of this blog post.
Prior to 1960, the impending question of whether nerves control muscle or muscles control nerves was hanging over many researchers heads. In 1960, researchers Buller and Henneman et al., experimented with taking out the nerve from a specific forearm muscle (fast muscle fiber) and using it to power a calf muscle (slow muscle fiber) – a process called “cross-reinnervation.” What they found was, the slow-twitch calf muscle became a fast-twitch muscle. Ultimately, it answered the question that nerves controlled the muscle; our nervous system regulated strength and muscle growth.
Because all nerves emerge from the brain and spinal cord, which is initially protected by the skull and neck spine, it only makes sense that if the structure of the Upper Cervical/Neck and entire neck spine is well-maintained, the human experience aka sensorimotor skills will function at optimum and thrive.
