My day job is the study of the neural control of human movement. For the past 3 decades my main activity has been training in the martial arts of karate and Okinawan weapons.
My interest in martial arts not only came first in my life (I started training in 1981 at the age of 13) but actually spurred my interest in science. I was interested in how people can move so fast with such precision in martial arts. I marveled (and still do) at how crazily complicated it must be for the body to do all the things I was able to do and my teachers were able to do better. That got me on the road to kinesiology, in which I hold a masters of science degree, and neuroscience, in which I hold a PhD. Shortly into my scientific career, I got interested in the neural control of movement and rehabilitation of walking after stroke and spinal cord injury (which continues as my main focus now). It is worth noting that extremely high level performance such as training to become Batman, and rehabilitation to improve walking are just different points on a continuum of performance. So, all the basic principles in terms of how the body responds to stress and training are the same, just applied slightly differently. Anyway, every day I study and teach about movement control and then practice and teach about how to do real martial arts movements. You could say I practice what I preach, and you would be right!
