Study of Speed In Throwing Arts

Laboratory of Sport and Health, Faculty of Sciences Sport and Physical Education, France.  seem to support what I have learned in the throwing arts. I also found this inRamdane Almansba post in Judo-the-Blog It Stated the following:

The aim of this work was to verify if there was a difference in throwing speed performance between heavier

and lighter weight categories in judo. Sixteen judoists aged 18±3 years-old, eight considered in the light weight category (-73 kg) and eight considered in the heavy weight category (+73 kg) participated in the study. A force/velocity test was used to determine the anaerobic power, strength, and pedal speed for each subject. Three trials of Nage-komi exercise, each comprised of 15s sets of Osoto-g

ari, Uchi-mata and Ippon-seoi-nage throws were performed by each subject to ascertain throwing speed. Throws within the sets were intersected by one period of 3 minute passive rest while the trials were separated by one period of 10 minute passive rest. Heart rate and the greatest number of throws within each set were measured for three trials.
We use

d an ANOVA to compare the number of throws between the two weight categories and a

“Student” test when the difference was significant. A correlation was used to examine the link between the different parameters.

show that in the force/velocity test pedal speed did not differ between the two categories. However, there was a significant difference between the two categories when throwing speed was measured by the number of throws executed during the Ippon-seoi-nage and Uchi-mata, but there was no significant difference between the two categories for Osoto-gari.

Our study showed that the throwing speed of judoists represented by number of throws appears to be significantly different between the two categories. The lighter category has more speed than the heavier c ategory using arm technique (Ippon-seoi-nage), while the heavier category has more speed using leg technique with half turn of the attacker’s body (Uchi-mata). As a result, throwing speed is related to the type of technique used and not weight category…”

Chatting With Mr. “Devin Willis”

I had a chance to talk with Devin on the phone last night and enjoyed it a lot!

When did you start your martial arts training?


My father  Donald Willis was my first instructor. He liked boxing a lot and some Judo. He taught me the basics of judo and boxing when I was very young…(no gi)

Later I would train in American Kenpo , Shotokan Karate  and Kung fu. In the later years I trained with Master David Lee in Modern Kung fu and became a teacher for him in San Jose California. I have had many teachers over the years, because I am always learning.

Through Family and friends  I met other martial artists like Ed Parker. (Not just karate people but boxers , wrestlers, aikido, judo…etc. In fact Damon(His brother) has trained with world class instructors, but keeps training with me(I noted this seemed to humble Devin)

It was a very interesting time. I met Mr. Parker of Kenpo and what a great man he was and I learned a lot by talking and listening. He was a good example of leadership in the Martial Arts AND is missed.

More to come-

Shuai Chaio and Chin NA In MKF

According to Devin Willis , “..Master David Lee was taught Shuai Chaio(Shuai Jiao), not Akido It also had entailed Chin Na. also, we were taught to also had strike as we to enter. In Shuai Chaio the main goal is to throw the opponent hard, at a very akward angles, and possibly breaking something along the way of the throw.

I was taught by my Instructor that Shuai-chiao was used by the bodyguards to the chinese emporers.

Our “drills”consited of full contact sparing , with the understanding a takedown was considered any part
of the body, other than the feet, touching the ground. You only got points for a clean throw, you had to remain on your feet and couldn’t be dragged down as well.

Also, once the two competitors “locked up” or made physical contact to initiate/repel, resist, we were given 4 count, if noone had been thrown the competitors were
seperated thus you had to go for the quick clean throw.

Many of the throws are similar to Judo, but sacracfice techniques are not used in sport version of Shuai Chaio (since whoever hits the ground first loses points). It is also illegal in sport Shuai Jiao to throw opponents with techniques that lock the joints.However , used Chin na and worked with joint locks..”
But in It is also illegal in street Shuai Chaio to throw opponents with techniques that lock the joints to break as they are thrown is  the version taught in MKF.

I have always wondered if Grandmaster Jimmy H. Woo and Master Lee ever crossed paths?

     San Soo kung fu is one of the most effective systems for self defense. Modern Kung fu is also known as an effective system.

I have always wondered if Grandmaster Jimmy H. Woo and Master Lee ever crossed paths? Devin was never sure
Grandmaster Jimmy H. Woo brought the art of San Soo kung fu to America in

around the 1930’s and was the first Chinese to teach non-Asians. From when he

opened his El Monte, CA school in 1958 until his death in 1991, he taught

thousands of fighters what many Martial artists consider the most brutally effective

martial art existing today. I have started to study it the last year and Modern Kung fu seems to perhaps mimic it in many ways?

-kicks and punches, leverages (chin-na), mauling and grappling techniques,

classical (staff, tri-sectional, knife, ) and


-unorthodox (chair, shoe, belt, etc.) weaponry, sweeps, throws, and

take-downs, and pressure point or nervous system strikes.


San Soo kung fu and Modern Kung fu are attack-based, first-strike-mentality art unfettered by sport and aesthetic considerations. Eye gouges , joint and neck breaks, biting, and many other “unethical” strikes are the san soo practitioner’s bread and butter. We believe fighting is not a game, but brutal, ugly, nasty business.

As the great warrior Miyamoto Musashi said, our sole intent is to step in and kill the enemy.

There is no other consideration. Since any martial artist will fight

exactly as he has trained, we never train with rules but with deadly

serious intent and a healthy respect for not only our partners, but for

every human being. True san soo kung fu is not for everyone; only for

those who are serious about real-life self defense against one or more

attackers, armed or unarmed. No silly animal postures. No endless

breathing exercises. Just the scientific study of street-fighting

principles and psychology. One of the reasons I had to leave Devin because of his religion of Mormonism, His Instructor Don Neal was a Lay Pastor and my current instructor is also a Christian(what is a Christian?.)

For more information on San Soo kung fu, you can contact

Master Mark Colby

P.s-Devin was an awesome man, teacher and fighter. He was just unsaved.

Sambo, Judo, BJJ, Catch Wrestling vs MKF’s grappling skills???

My thoughts on a question that was posted about Sambo, Judo, BJJ, Catch Wrestling vs Devin’s grappling skills???

The question has been answered on how MKF does against the different type opponents (small examples see detail here and here) I do understand an instructor in Modern Kung Fu was beaten by a Gracie (Royce) in the eary 90’s . Since then Most MKF families have enchanced the ground game. However Devin has kept to his training as he always been taught.

If one was to watch Devin Willis or a person who trained with him was to us grappling skills only . It would seem as a modifed Greco-Roman , Freestyle wrestling, Shuai Chiao and Judo . clinching, takedowns and throws,

Note Devin always taught to soften with strikes using modifed Muay Thai, boxing Kenpo to improve the striking aspect of the clinch.

On the Ground:  a mkf person uses modifed Chin na Brazilian Jiu-Jitsu, shoot wrestling, catch wrestling, Judo, and Sambo are trained to improve submission holds, and defense against them. we use  the WEB to tied opponents arms up. Other people have thoutht Devin used modified Jiu-Jitsu, pankration, and styles of amateur wrestling are trained to improve positioning and maintain ground control . They are correct

Master David Lee

In San Jose, California during the early 1970s a method of combat by the name of Modern Kung Fu which also means “New Hard Task” or “New Work”. The founder name was Master David Lee.

Master Lee had studied many different systems of martial arts in China starting as a very young boy. Some were Pa kua chang, China’s wrestling, Shaolin (martial arts) Hung Gar, Monkey, Eagle Claw, Crane, Drunken Monkey, Tiger, Mantis.

The Main goal in MKF as in most styles of martial arts is to become a better human being. MKF is for defense of different zones, 1-5 the Modern Kung-Fu community utilizes the following breakdown grappling range, trapping range, punching range, and kicking range. Names are merely labels, though. In punching range, you can punch if you would like, or you might do anything else (such as an eye-strike) that would work efficiently within that range. The number of categories that is used is also optional.

In MKF, is known for its ability to adapt to different attacks and defense. The goal of a student is that he/she can defend themselves from any position. This system does not believe in any set techniques, instead it holds to studying movement of the human body

Sanshou + Modern Kung Fu?

I had studied Sanshou or Sanda for over 15 years and Devin threw me aouound like a baby.which is humbling-Sanshou modern Chinese hand to hand combat, self-defense system, and combat sport. Rather seen as an independent style it is consider just one of the components of chinese martial arts and is normally taught alongside other wushu.

The term Sanda has a longer history and is more commonly used. Sanshou was the official name given to the martial art when it was formalized and standardized by the Chinese government. Later the official name reverted back to Sanda.

It is composed of some aspects of traditional martial arts fighting styles in China, but mainly based on scientific one on one combat efficiency. Sanshou is composed of chinese martial arts applications inculding most aspects of combat including striking and grappling. Sanda tournaments are one of the two sport wushu disciplines recognized by the International Wushu Federation

As an unarmed self-defense system, Sanshou includes punches, kicks and grappling (throws, locks, chokes)

Mr. Devin Willis seems to use a more effective Sanshou-He just called MKF

Some Sanda (Sanshou) fighters who are well-known in the U.S.A. include the IKF champion Cung Le, Rudi Ott, and Marvin Perry. Some well-known Sanda fighters within China itself include Yuan Yubao and Liu Hailong who was once called “The Conqueror of Muay Thai”.

Modern Kung Fu(systems used)

Kosho Shorei Ryu
Kosho Ryu is an ancient art form founded in about 1245 AD by a monk. Legend has it that this stranger meditated under an old pine tree and discovered the meaning of true self-defense. Self-Defense with no body contact is the highest physical art. Kosho Ryu artists learn to move such that opponents cannot see, feel or hear them. By manipulating the attacker perception of their environment, they are able to control their movements, force and aggression. Today the temple still stands strong in Japan as it did centuries ago. However, there is no practice of Kosho Ryu at the temple at present, as the monks spend most of their time with their religious practices. The most apparent reminder of the past is an old plaque found on the temple grounds dedicated to the monk.
The direct translation of Kosho Ryu is “the study of natural laws”, “the way of enlightenment” through motion and movement. There is no other art like Kosho Ryu. It is not a “style” or “system” but rather an understanding or process. It is a study of the natural law of motion and movement. The student learns that all the seemingly diversified art forms function by the same set of natural laws and principles. In doing so, the student learns to accept and deal with life as it is and not how they wish it to be. Kosho is about the process of study. Its combative arts are devastatingly effective but only represent a part of what Kosho Ryu is all about. The art form builds healthy character and allows the student to expand their abilities beyond expectations.

Kosho Ryu students learn to pay attention to their environment and to themselves. As a result of this natural law approach, the principles of Kosho can easily be integrated with any art. These principles will lend new insights and a quantum leap in understanding to even the advanced practitioners of martial arts.

Material taught in the Kosho Ryu curriculum include the understanding of prepratory arts, human body and its systems, restorative arts, escaping arts, healing arts, weaponry, philosophy, internal arts, weaponless forms of self defense.

Kosho Ryu is more than just a fighting art, it is a way of life complete with a socially significant philosophy that is capitalized in the term “self-defense”. Only in the most extreme situations of life threading aggression are the fighting aspects of the art brought into play. The fighting arts themselves are designed to bring the opponent to the awareness of their wrong doing rather than to harm them. Kosho Ryu is the development of restraint, propriety, humbleness and integrity.


Arnis / Kali / Escrima
Arnis began in the Philippines over 1200 years ago. It was the fighting technique used against the Spaniards in the 1500’s. Today Arnis is the main martial art in the Philippines and defiantly the most popular. Modern Arnis was developed and refined by Remy Presas. The word Arnis is taken from the term “Arnis de mano” or harness of the hand. Arnis (practiced in northern Philippines), Kali (practiced in the southern Philippines) and Escrima (practiced in central Philippines) are all essentially the same art.

Arnis practitioners utilize empty hand techniques and weapons such as sticks and knives. There are different forms of combat which use different types of weapons such as a long wooden sword and a short wooden dagger. There is a single stick and double stick Arnis which uses one or two 2 foot long stick(s) made of wood or cane.

Arnis is a serious form of self defense but it is often seen as a sport. It uses almost all hand techniques, striking and parrying and depends strongly on strategy. Students train with drills, sparring and in free style practice and the training is very physical and strenuous.

Arnis practitioners also develop mental, emotional and spiritual qualities.


American Kenpo
A style of Karate developed in the West. It deviates from traditional Karate in several important respects. First, the terms used are in language of the country in which it is being taught. Japanese is not the language of instruction. Also, students are encouraged to change and adapt the techniques. The school emphasizes vital point attacks using punches, strikes and kicks. Throws are also important. The art was original introduced in Hawaii by James Mitose, near the start of World War II. Later, William Chow, one of his students, adapted Mitose’s approach and “Americanized” the art. Ed Parker, who is probably the most famous practitioner, was a student of Chows and further adapted the methods so that they would prove practical in an actual fight. He created a logical organization for the basic Kenpo techniques, dividing them into eight categories., such as stances, blocks, punches and so on. These are taught in forms, in self-defense practice, and in free-style sparring. (From The Martial Arts Encyclopedia by Jennifer Lawlerand interview with Devin Willis)

Kenpo is a mixture of five cultures (in historical order): Chinese, Japanese, Okinawan, Hawaiian (before Hawaii became a state) and American.

The word Kenpo is Japanese for “Fist Law” (Ken/fist, Po/Law) which in itself is confusing for this art started in China. Most people have heard of “Chinese Kenpo” or “American Kenpo.” But Japanese? (For point of reference “Fist Law” in Chinese is CH’UAN FA.)

The name is the result of centuries of development and change. Despite it’s birth in China, the art of “Kenpo” was passed down through the Mitose family who studied the original art in China in the 1600’s and brought it back to Japan. The Mitose family were Japanese, so, naturally they used Japanese to describe their family system.

James M. Mitose moved from Japan to Hawaii and the style he taught there was called “Kenpo Jiu-Jitsu” (He wrote a book in 1953 called: “What is Self Defense? (Kenpo Jiu Jitsu).

James Mitose’s second Shodan was William Chow. In 1949 Chow opened his own Kenpo club and he used the term “Kenpo Karate” to try and distinguish his system from “Kenpo Jiu Jitsu.”

In the early 1950’s Ed Parker (who was a Judo Shodan) started to take Kenpo Karate lessons with W. Chow. In 1956 Ed Parker moved to Pasadena, California where he opened his own Kenpo Karate school. Ed parker would later become the foremost pioneer of Kenpo to the American mainland. Ed Parker’s 5th and 6th black belts were Al and Jim Tracy.

Through the years of 1956-1960, Parker’s system of Kenpo was called “Original Kenpo” because it was identical to that Mitose and Chow taught. (Parker called his system simply, “Kenpo Karate.”) In 1961, Ed parker and Chinese Gung Fu Master, James Wing Woo co-founded, “Traditional Kenpo.”

So, Kenpo has had a lot added to it over the centuries. Please don’t take this short summary as a suggestion that Kenpo is not a “set” art. On the contrary, after so many years of development the Kenpo system knows what does and doesn’t work, because of the fact that the style has been handed down from one generation to another for hundreds of years. (They have had a lot of practice.)

Many people call Kenpo the “ultimate in self defense.” Kenpo training emphasizes a scientific approach to combat. Kenpo disables an attacker with quick, efficient techniques. Kenpo has a counter for every kind of grab, punch, strike, charge or push. The counters range from simple escapes to joint locks, brakes, blocks, strikes and joint and nerve strikes.

The History of Shootfighting

Shootfighting might be the most all round martial art the world has ever seen. The best styles of the world have contributed with their specialties. Stand up fight from muay thai, clinch and take downs from judo and Wrestling and from sambo and ju-jutsu the ground fight. Stand up fight and ground fight is equally emphasized. There is always something new to learn as a result of the versatility. Since you can specialize on the training that suits you, it never becomes boring.

Brazilian Jiu-Jitsu, among other styles, has during the recent years showed the importance of well working skills in grappling. However, the stand up fight can not be left in the background. Shootfighting is the style that combines stand up fight, clinch and ground fight the best. It has become a success. Fighters who train according to the shootfighting concept dominates within the NHB. Here you can find fighters as Bas Rutten, Frank Shamrock, Randy Couture, Maurice Smith and others.

Shootfighting was created when a German wrestler, Karl Gotch, was teaching “real Wrestling” or “shooting” to a group of Japanese elite fighters. Two of the fighters, Masami Soronaka (karate, judo and sumo) and Yoshiaki Fujiwara (muay thai/kickboxing and judo) created what was called UWF or “hard style” in Japan. Fights have been arranged during more than 10 years.

Bart Vale took the style to the west. He was the first champion who was not Japanese. Bart was also the person who came up with the term Shootfighting.

Shootfighting became well-known all over the world through UFC and other NHB arrangements. It is the third most popular “audience sport” in Japan and is continuing to grow fast.

It is important to emphasize that Shootfighting unlike UFC etc. is a sport with certain limits. This is to protect the fighters and improve the quality of the techniques.


Muay Thai
Muay Thai is the martial art of fighting with one’s bare fists, utilizing elbows, knees, feet and fists as weapons. No one knows when Muay Thai first began, it is assumed that Muay Thai had been practiced since the beginning of Thai history.

In the old days, Asian men of Mongolian descent from China down to the Malaya peninsular fought their wars face to face, fist to fist, unlike their Caucasian counterparts in Europe, who concentrated on developing weapons with which to fight. For this reason personal capabilities played a major role in the art of fighting and an efficient martial art was extremely important. Muay Thai is one of the most efficient martial arts.

Since modern technology did not exist in ancient times, Thai children did not have mechanical toys to play with. Instead, they used their bodies to play games. Those simple games served as basic exercises for Muay Thai. They made parts of the bodies ready.

Muay Thai involves all parts of the body. The students of Muay Thai learn about the body’s weak points and understood how to exercise one’s physical parts.

‘Nawa-attawut’ or the 9 principal weapons in Muay Thai include head, two fists, two elbows, two knees, and two feet. In addition, there are combination weapons which are two shoulders, arms, bottom and the outer parts of the ankles: The practice of using both the principal weapons and the combination weapons in Muay Thai requires not only hard work, but the proper steps and great endurance.

The training involves rigorous physical training, similar to that practiced by Western boxers. It includes running, shadow-boxing, and heavy bag work. Much emphasis is also placed on various drills with the so-called “Thai pads”. These pads weigh five to ten pounds, and cover the wearers forearms. In use, the trainer wears the pads, and may hold them to receive kicks, punches, and knee and elbow strikes, and may also use them to punch at the trainee. This training is vaguely similar to the way boxing trainers use focus mitts. The characteristic Muay Thai round kick is delivered with the shin, therefore, shin conditioning is also done.

Little or no free-sparring is done in training, due to the devastating nature of the techniques employed. Thai boxers may box, hands only, with ordinary boxing gloves. Another training drill is for two fighters to clinch, and practice a form of stand-up grappling, the goal of which is to try to land a knee strike. However, full-contact kicks, knees, and elbows are typically not used in training.


Aikido is a Japanese martial art developed by Morihei Ueshiba (often referred to by his title ‘O Sensei’ or ‘Great Teacher’). On a purely physical level it is an art involving some throws and joint locks that are derived from Jujitsu and some throws and other techniques derived from Kenjutsu. Aikido focuses not on punching or kicking opponents, but rather on using their own energy to gain control of them or to throw them away from you. It is not a static art, but places great emphasis on motion and the dynamics of movement.

Upon closer examination, practitioners will find from Aikido what they are looking for, whether it is applicable self-defense technique, spiritual enlightenment, physical health or peace of mind. O Sensei emphasized the moral and spiritual aspects of this art, placing great weight on the development of harmony and peace. “The Way of Harmony of the Spirit” is one way that “Aikido” may be translated into English. This is still true of Aikido today, although different styles emphasize the more spiritual aspects to greater or lesser degrees. Although the idea of a martial discipline striving for peace and harmony may seem paradoxical, it is the most basic tenet of the art.
