Question: Can body-control be optimized?

My hypothesis: If a mechanical system has scalar control metrics (efficiency, flexibility, power, strength etc), those can be optimized. Bodies and brains are not exceptions. The optimum motor map for a continuous mechanical and representational system (like a body and brain) will itself be smooth and continuous, and should carry the kinaesthetic percepts of ease and lightness, along with the sensory percepts of clarity and illumination. So that optimum could be called "neuro-mechanical enlightenment."

Summary: Apparently spiritual states like "enlightenment" or "grace" in fact refer to states of optimal neuro-muscular control.

Tests: Choose a reasonable neuromechanical performance metric, such as micro-stability standing on one leg, or the bandwidth or entropy one can control through the spine or feet. Investigate correlations between that metric and other non-culturally-inflected metrics of emotional or intellectual self-consistency and flexibility. A significant positive correlation could in principle be extrapolated toward an optimum, even if no living examples of the optimum are available for study.

Refutation: Show the absence of that correlation, i.e. that statistically those with hyper-functional emotional and sensory systems are no more likely than average to have hyper-functional motor systems, or vice versa. (Note: given that modern society discourages certain kinds of hyper-functionality and hyper-sensitivity, these metrics must be purely biophysical, uncontaminated by culture).

(It seems to me that yoga and other somatic/spiritual disciplines emphasize a deep link between physical coordination and mental clarity, even to the point of associating spinal locations with specific emotions, as with the chakra system. Furthermore, my friends who experience neuromuscular "releases" of the hips and spine often report concomitant feelings (like peace or energy), and sudden insights).
