About This Blog


Welcome to my blog.

I was writing a how-to book on the jujutsu of Jan de Jong. The initial intention was to include a little science behind the how-to instruction to add depth of understanding to those tactics and techniques. The research into the little science evolved into the little science overshadowing the how-to instruction. So, I decided to write a book dedicated to the science behind the tactics and techniques of the martial arts. After a year or two, I begrudgingly accepted the fact this book would be huge and consume even more years of my life. So, I decided to cut my losses and write a series of books based on the information I'd already accumulated.

My first book is tentatively titled: Throwing Techniques and Takedown Techniques of ALL Martial Arts. Throwing and takedown techniques are quite popular these days because of their popularity within the Brazilian jiu-jitsu and Mixed Martial Arts community. However, all techniques which are designed to bring a person to the ground are lumped into the one category. That category is either referred to as throwing and takedown techniques, throwing techniques, or takedown techniques. If there is no difference, why refer to two types of techniques. I, for the first time, provide a biomechanical distinction between the two types of techniques, and, I demonstrate why classification itself is the core of all learning.

The next book, which I'm currently working on, is applying the concepts and theories of a relatively new science, injury science, to understand and study techniques that result in blunt or penetrating injuries. Injuries are at the heart of martial arts tactics and techniques. The avoidance thereof and often through the infliction or threat of infliction. Included in this chapter is a chapter on pain. The pain discipline explains that we've learnt more about pain in the last 10 years then we have in the last 1,000. For the first time, the knowledge of these two disciplines, which relate to the very heart of the tactics and techniques of the martial arts, are used to understand and study the tactics and techniques of the marital arts and those used in any experience of interpersonal violence.

The next book is tentatively titled: Beyond Fight of Flight. In that book I integrate the theories and concepts of two disciplines (the emotion and stress discipline) that study the same process to provide a comprehensive model to understand the evolved human response to harm, threats or challenges. What you have read about the fight or flight response is just one part of the elephant of Indostan.

The driving imperative of my work was adopted from Dr Attilio Sacripanti, author of Advances in Judo Biomechanics Research, and Chair of Biomechanics of Sports at the University of Rome Tor Vergata. The science has to facilitate the understanding and study of the tactics and techniques of the marital arts, otherwise, it is of academic interest only and I am all about the practical.

This blog was originally initiated to share my work with interested readers and encourage interest in my work. Since then, I've commenced sharing other information that is available, mostly in academic journals and that would normally never see the light of day, with practitioners that might find it interesting and even useful. Based on unexpected demand, I've also taken the opportunity of telling the unauthorised story of Jan de Jong and his school of thought. As I work through this story, it has the potential of being a case study for the evolution of martial arts schools and schools of thought.

This blog was also originated to assist me. As Stephan King said: If you want to be a writer, you must do two things above all others: read a lot and write a lot. I've read a lot, I'm reading a lot, and now I have to write a lot.

I hope you enjoy my work and I would appreciate any feedback - positive or negative, as it only adds to the quality of my work.
