Judo - Skill Is the Practical Application of Technique
January 13, 2020
The words technique and skill are often used to mean the same thing, yet they are separate and interdependent. This article is devoted to exploring what skill and technique are, and why it's important to understand how they work.
The Core Concepts of Throwing Techniques - December 30, 2019
The purpose of a successful throwing technique in sambo is to get an opponent to the mat or ground as effectively as possible with control. A sambo grappler can win a match outright by a total victory by throwing his opponent to the mat with control (largely on the back or backside, or if the opponent lands in a bridge) with the thrower remaining standing at the conclusion of the throw.
Sambo-Not for the Faint of Heart - November 25, 2019
The young newspaper reporter was looking for an angle on his story about the national sambo tournament I was hosting sometime back around 1985 in Kansas City, Missouri. I had given him the necessary background information on the sport; the rules, history, who was competing that day and the other bits of information that would give the reporter more than enough information to provide an interesting story to his readers.
Structured Training in the Martial Arts - October 14, 2019
Structured training is not only necessary, it is essential and central to success in any field of endeavor, and especially so in the fighting sports that comprise the martial arts. A person has to train hard, but just as important, that martial arts athlete has to train smart. In most martial arts, there is a rational approach to skill development.
Teaching, Learning and Training for Juji Gatame - September 30, 2019
Juji gatame is a core skill for all combat sports. The study of this armlock teaches fundamental skills that go beyond simply stretching an opponent’s arm. It is a useful, reliable tool with a high rate of success used in all combat sports and can be used by both male and female athletes in all weight classes.
Juji Gatame: The World’s Most Popular Armlock - April 29, 2019
There are, fundamentally, two core ways of “locking” an arm. You either bend it over a fulcrum to cause pain or you straighten and stretch it over a fulcrum to cause pain. Juji Gatame is one of four primary armlocks that attack the elbow joint (as well as shoulder joint).
The Three Building Blocks Of Learning And Training In Judo - April 1, 2019
In any field of study, there has to be some kind of structure so that the contents of that particular area of study can be logically understood, taught and learned, and ultimately passed on to others. This structure or framework must have a firm theoretical and philosophical foundation based on practical application and, just an important, allow for innovation to take place. It must be fixed, yet flexible so that the activity (in this case judo) has room to grow.
How Biomechanical Principles Apply to Judo - March 11, 2019
Judo is based on sound biomechanical principles. The more efficiently a person applies these principles, the more effectively that person will do judo. To do judo well, a person must know not only how to control his own body but also his opponent's. The Japanese phrases, terms, and names—in use since judo's inception and familiar to all judo practitioners—explain much of what judo is and does.
Judo Isn't Gentle - February 18, 2019
Is judo really the "gentle way?" In the popular meaning of the word, judo certainly isn't anything close to being gentle. To paraphrase the great martial arts writer Donn Draeger; "Judo isn't gentle." And while judo isn't gentle in the more common use of the word, it's certainly efficient; and because it's efficient, it's effective
Brain Damage: Do Football Helmets Help? - September 5, 2016
Recently, the National Football League is facing a 765-million-dollar lawsuit filed on behalf of more than 4,500 former players regarding the concussions and potential chronic traumatic encephalopathy (CTE) sustained during their careers. Similar lawsuits are underway against the National Collegiate Athletic Association as well as the National Hockey League, and football helmet maker Riddell is facing multiple lawsuits over claims about the effectiveness of their helmets at protecting athletes from concussions.
Foam or Knuckles—Navigating the Illusion of Safety - January 18, 2016
If you really want to understand how gloves contribute to the safety of our athletes, especially when it comes to their brains, take a closer look at the physics behind taking a punch with a bare fist or a glove.
Guns, Knives, and the Hollywood Death Sentence - September 21, 2015
In order to become a successful screenwriter in Hollywood, you need to watch a lot of movies, so you can learn from the screenwriters who came before you, and so you can get a feel for what else is out there and popular today.  Unfortunately, this important part of a screenwriter's education is also how Hollywood ends up propagating and recycling incredibly stupid ideas over and over again to the point where the audience just accepts it without question.
Protecting the Brain from Trauma: A Home Experiment to Show We Can Do Better - September 7, 2015
If you put on a football helmet right now and smacked yourself in the head with your hands, you might notice you can hit yourself pretty hard before you start to feel pain. You could even grab a stapler or a coffee mug and hit yourself with that. If you are like me, smacking yourself in the head is the first thing you do when you put a helmet on, just to test it out.
Interpreting The Kanji - June 2, 2015
Studying an Asian martial art can be a daunting task for a non-Asian student. Not only do you have to learn the physical postures and how to move from one to the other, you also strive to master the seemingly endless number of techniques. As well, the cultural milieu in which the martial art developed is often confusing. Many times the task you undertake is compared to climbing a mountain, and for good reason.
Gichin Funakoshi (1868–1957):  The Gentle Teacher of Shuri Te - December 1, 2014
Perhaps it was always Funakoshi's destiny to shed light on a part of Okinawan culture that had for centuries remained hidden from the gaze of the general population. He shone like a bright star in a dark sky and pointed the way forward for the many millions around the world who would take up the challenge of learning.
Fond Memories About Okinawan Cuisine - November 3, 2014
I once asked a Japanese friend of mine, who had flown down from the mainland to Okinawa to meet me, if she was enjoying her visit to this part of Japan. Her reply surprised me at the time, as she confessed it was like visiting a different country. The food in particular was very different from the type of dishes she ate on a daily basis with her family in Osaka.
Modern Trends: Reality-based Martial Arts - September 15, 2014
The rise in recent years of so-called ‘reality’ based martial arts reminds me of other great scams committed against the general public, like bottled water, and who can forget the panic that gripped the world in the 1990s over the Y2K dilemma that was supposedly going to see aeroplanes fall from the sky and shut down every computer on the entire planet.
Bunbu Ryo Do: The Way of The Karate Martial Scholar - March 10, 2014
In the early part of the twentieth century, when Okinawan karate teachers were first asked to provide names for their karate by the Butokukai in Japan, they struggled to come up with a name that did justice to the martial art they practiced.
Difficult Research in Developing Karate—Part 2 - November 11, 2013
Personal research requires you to look inward towards your own nature, and to take responsibility for your karate; to step out of your comfort zone. You can do this by attending events like open courses if you like, but in truth, such challenges do little to aid your progress.
Difficult Research in Developing Karate—Part 1 - November 4, 2013
“Karate training is easy!” Now there’s a statement to get your head around. But is there any truth to it; is training in karate easy? Well, children, the unfit, the lazy, and folks of dubious character…all seem to have no problem being awarded a black belt in karate these days, so the training must be easy…right?
Unraveling Knots in The Thread of Life - October 14, 2013
Over a period of about eight years, beginning in the early 1990s, I began taking a closer look around the world at the various religious and philosophical beliefs people held, and saw in many of them much to be admired. I also noticed there was quite a lot of common ground. I was initially astonished to discover, for example, how the sacred text of Judaism, the Torah, tells the same story as the first five books of the Bible, known to Christians as the books of the Old Testament.
