Dojo Kun – Shotokan Training Hall Principles
These kun are the guide, philosophy, mind set to your training. Each rule is numbered "1" because each has equal merit. The Dojo kun are not to force morality, but remind of universal positives. Instead of mindlessly repeating as a chant, you remind yourself of using training for good daily mindset.
With each training session at the JKA dojo, students kneel in seiza and repeat these five precepts out loud. There are several different translations:
1) Seek Perfection of Character (Work to be good) - Jinkaku kansei ni tsutomuru koto.
1) Defend the Path of Truth (Be sincere) - Makoto no michi o mamoru koto.
1) Foster Spirit of Effort (Put maximum effort into everything you do) - Doryoku no seishin o yashinau koto.
1) Honor the Principles of Etiquette (Respect others) - Reigi o omonzuru koto.
1) Guard Against Impetuous Courage (Develop self-control) - Kekki no yuu o imashimuru koto

Comparison of a Front Punch Using High Speed Filming - Difference Between Experienced and Novice
by Dr. Jolie Bookspan
In the mid 1980s, I did many studies investigating which differences in human movement determined injury potential and athletic performance. In another kind of study, I wanted to know what made the difference between the punch of a black belt martial artist, and the same punch by an athletic person without training.
In present day, a computer directly picks up the locations of the person's joints at each point in time, generating a three dimensional computer image of the person as they move in real time. Software automatically calculates, draws, and records the image.
Back when I did these studies, we didn't have any of that. I did it all manually. I filmed two subjects using 16mm high speed filming. An athletic man who had never done martial arts was subject #1. My husband Paul, who had earned his black belt a few years before that, volunteered as subject #2.
I put markers over the center points of their major joints, and bands around joints which initially faced the camera but would rotate during the punch, so that the joint center would still be determined. Both executed a front reverse punch with their dominant arm. (Paul had to use traditional hyperlordotic position, rather than healthier neutral spine position, just for this comparison. I have done other studies comparing my neutral spine adjustment and found it to be a stronger punch, try it on my page for Fixing Swayback.
After waiting a week for film developing, I went into a darkened lab and used a film projector to throw the image of each of the thousands of frames, one by one, against a large computer digitizing tablet hung on a wall. I then digitized each joint point of each projected image, in each frame, of both subjects, frame by frame, with a digitizing Graf-pen. I sent data points from each frame by (300 baud acoustic coupling) modem to a text editor on a mainframe in another building at the University's new computer center. I wrote my own FORTRAN programs to generate data summaries and used packaged International Mathematical and Statistical Libraries (IMSL) cubic spline programs and subroutines for data smoothing. This was all to get each knee, hip, ankle, shoulder, wrist, elbow, neck and other filmed joint points into a computer to see exactly where and how fast they moved. Projecting each frame against the wall also allowed me to trace the subjects' outlines to make series of line drawings of their punch, and to make stick figures showing joint center placement. Here are some data and the actual drawings I made. I need to get them scanned in higher resolution next Until then enjoy:
The untrained subject is below, first
Below is Paul Sensei
Paul is left handed so I had to reverse the images to make exact comparisons.
Below are comparisons of the angular velocity of each subject's wrist, elbow, shoulder, and hip
Below are comparisons of the angular acceleration of each subject's wrist, elbow, shoulder, and hip
Below are some center of gravity calculations and comparisons.
As you can see, there was a lot of hand-calculation and charting back then.
Then I could use an advanced machine called a typewriter so that I didn't have to hand write the entire study paper.
Not long after, with improvements in automating this process, action video games were first flourishing. I was invited to a computer-generated imagery (CGI) development studio to be their "movement representation figure." They put the dots on my joint centers and filmed me using high-speed 3D computer graphics modeling as I did martial arts and tumbling moves. Not just one punch, painstakingly done, but jumping, spinning, flying all over the studio, and up and down walls.
The software automatically generated a mathematical, "wireframe" 2-D representation of my three-dimensional form. From it they animated a wild female warrior action figure for their fighting/mission genre arcade and video gameplay. They also used skeletal animation for when I would morph (on-screen) into various animal forms. I never got royalties but it was fun.This is a big fun topic. I can post more about motion capture analysis of various sports if anyone is interested.
