Proprioception: the unconscious perception of movement and spatial orientation arising from stimuli within the body itself....or, as I like to think of it: your nervous system used in concert with your native design.
When I ruptured my ACL, I entered a wonderful physical therapy program via OSU. This is not a post about that, but rather about a simple comment made by Robin, one of the therapists. We were talking about repetitive load and wear and tear on joints. If your body has any bias, just like any degree of misalignment of your car, you will wear the equipment unevenly (tires versus cartilage). She mentioned after many years of road running, she and her husband had mitigated a lot of their current pain, and also based on the comprehensive evidence of the field, expected to alleviate much of their continued biased wear (= arthritis development) simply by running on trails in varied terrain......small stuff, BIG consequences.
I would assert that adding barefoot running as part of their program would also yield huge benefits as it promotes "natural collection" and a varied and complete use of the body https://www.youtube.com/watch?v=7jrnj-7YKZE. First, the foot is generally used differently. You land on the ball of the foot, as opposed to heel, and create a smaller peak impact load better absorbed over a greater time interval (better use of your native bungee system, see post 2014/7/14/hoof-and-body-by-aidan). Second, you have this wonderful and fun piece of life you may never have enjoyed before, or at least not since you were a toddler, ie the interaction of your proprioception system with the earth and the weight of your body, which is an amazingly diverse and rich physical experience. From your body's perspective this physicality is like comparing "Row, Row, Row your Boat" 's complexity (running shoes) to that of a full orchestra playing a symphony (bare feet!). Rich and delicious and effortliss health benefits come from the implementation, or symphony of use, of your native design.
Now, I have to chuckle, because people get hurt running in shoes (our equivalent to hoof boots) as well as barefoot. It is up to YOU to develop your common sense over the course of your lifetime. I still remember a news program that asserted that yoga caused a large number of serious injuries a year.....YOGA????? How out of touch with your own body are you if yoga poses a threat to yourself?
Common sense......the art of self responsibility.
So, in sum, simple or small decisions = big lifetime benefits or losses. We tend in this society to skip over that which would yield the best and most wonderful in our lives. Don't. Slow down. Smell the roses. Think and produce excellence and love and let your intellect, body and soul grow from that fertile soil.
