Koyūjuyō [固有受容]
A primary concept of learning martial arts, or any physical endeavor such as darts or golf or basketball etc., is teaching the mind and body proprioception to increase or speed, to instinctively know our body position and how to maximize our rotation in our environment while maintaining balance and orientation. Think of it as an internal gyroscope (a poor symbolism but sufficient for this article).
Often referred to as a “sixth sense.” Proprioception is our ability to know the exact position, speed, and rotation of all parts of our body without conscious effort.
It’s not sensing something external to our body, but sensing something internal to the body.
This sense is far more efficient and faster than using our vision to do the same job.
Vision is pretty slow and Ill-suited for helping one move through the world on its own, compared to Proprioception.
The incredible speed of Proprioception is critical to having control over our bodies.

Notes:
Proprioceptive signals from mechanoreceptors of the joints, muscles, tendons, and skin are essential for the intact neural control of movement. (I extrapolated this as a benefit of chinkuchi)
Broadly defined, proprioception refers to the conscious awareness of body and limbs and has several distinct properties: passive motion sense, active motion sense, limb position sense, and the sense of heaviness (Goldscheider, 1898). However, it has long been established that proprioception has an unconscious component in which proprioceptive signals are used for the reflexive control of muscle tone and the control of posture that has long been recognized (Sherrington, 1907).
proprioception requires movement. (Kata requires movement; balance requires movement; fense requires movement, etc.)
any form of motor learning is associated with proprioceptive processing and thus may train proprioception. (Benefits of kata in karate)
the acquisition of motor skills, even those that are typically viewed to be visuomotor tasks such as reaching for objects or throwing darts, constitute a form of proprioceptive training.
Proprioceptive training is an intervention that targets the improvement of proprioceptive function. It focuses on the use of somatosensory signals such as proprioceptive or tactile afferents in the absence of information from other modalities such as vision. Its ultimate goal is to improve or restore sensorimotor function. (A bad term but you get the idea, i.e., “muscle memory”; may be better term instead of)
Studies seeking to train balance applied a multitude of activities including walking and stair-stepping exercises, single and double leg balance exercises with and without vision, sit-to-stand exercises, standing, walking, or jumping on stable and unstable surfaces and sport specific exercises

Proprioception is necessary for precise and fluid movements, making it essential to athletes and non-athletes alike.
Proprioception relies on the relationship between the body’s central nervous system and certain soft tissues, including muscles, tendons, and ligaments (can you say “Chinkuchi?).
Continuous Effort: ongoing continuous effort is a method that effects proprioception (can you say repetitive practice).
Our entire body has tubular parts of each cell called axions that carry impulses to the brain so it knows the exact position of every part of our bodies. In the brain is the somatosensory cortex, that calculates the geometric adjustments necessary to land, say, your finger exactly on your nose with your eyes shut.
kinesthesia focuses on the body's motion or movements, while proprioception focuses more on the body's awareness of its movements and behaviors. This has led to the notion that kinesthesia is more behavioral, and proprioception is more cognitive.
The sense (kinesthesia) that detects bodily position, weight, or movement of the muscles, tendons, and joints. Sensation or perception of motion.
The technical definition of kinesthesia is "awareness of the position and movement of the parts of the body by means of sensory organs (proprioceptors) in the muscles and joints." The literary definition of kinesthesia is similar: it's a type of imagery that evokes physical bodily movement, like a heartbeat or breath cycle.

Gyroscope: a device consisting of a wheel or disk mounted so that it can spin rapidly about an axis which is itself free to alter in direction. The orientation of the axis is not affected by tilting of the mounting, so gyroscopes can be used to provide stability or maintain a reference direction in navigation systems, automatic pilots, and stabilizers.
