Welcome to our diverse training regime at Ferus Fitness Fight Club in Prague, Czech Republic. The first video shows our strength and conditioning routine. Training sessions range between one to two hours long. We use basic tools such as kettlebells, Exercise balls, rubber resistance bands, Punching bag, and fitness balls (5kg, sand filled). Circuit training consists of one or two minute intervals with twenty to sixty second breaks to prepare for the next exercise.
• 13 minutes 19 seconds
This next video is a private session focusing on various kickboxing combinations. Attention is given to balance, technique, and speed, in order to reach maximize achievable power. Each student works towards reaching that maximum power within their own physiology – body weight, height, and gender.
• 12 minutes 40 seconds
The third session focuses on training younger children on various kickboxing and self defense techniques. In this session we concentrate on fighting stance, balance, as well as punching and kicking techniques. Training can begin as young as six years old.
• 16 minutes 49 seconds

• In this Martial Arts • Fighting Science paper we will discuss the psychology and physiology of fighters in combat. This first article investigates the changes in entropy when two opponents fight. Entropy is the measure of “order” in a particular system. In the context of fighting, low entropy means a high level of control. High entropy means low control or high disorder. The exchange between two fighters can be a series of punches, kicks, elbows, knee strikes or even grappling on the ground.
• During a fight the level of entropy increases. In an exchange each opponent has their own “fighter’s curve”. We can visualize this curve in a graph where the y-axis represents entropy, and on the x-axis is time. The longer it takes for an exchange to take place between two opponents the higher the entropy. In other words, both fighters lose some level of control in an exchange. But the rate at which the fighter loses control depends on their experience, technique, “heart”, strength and conditioning.
• Novice fighters are very uncomfortable at high entropy. Martial artists that focus on self-defense also have little tolerance for high entropy. In self defense disciplines, the defender wants to block and strike the attacker. Once that has occurred then they anticipate the end of the fight. Their entropy curve is sharp because a long exchange of strikes is not desirable. Kickboxers or boxers, on the other hand, have a shallow fighter’s curve. They are comfortable with a flurry of combinations, and will even stay in striking range for long periods of time while simultaneously blocking, moving, and counter-striking.
• The problem escalates when a fighter’s curve passes a threshold where they no longer know what’s going on. This is called the “chaos threshold.” High entropy can eventually lead to chaos – especially for inexperienced fighters. In this zone a fighter has lost complete control and tries to survive mainly through instinctive reactions. Once the fighter passes the “chaos threshold” they enter the “chaos zone“. In the chaos zone the fighter is most susceptible to a knockout or sever injury because they’re no longer completely aware of their surroundings. Fear easily takes over in this zone, resulting in the fighter closing their eyes and cover their face. In the chaos zone technique, timing, and power are significantly compromised. With the onset of panic the fighter may “turtle” (enter a fetal position).
• Fear also causes a fighter to hold their breath – either when being attacked, and even when attacking. This accelerates exhaustion because the lungs and muscles are deprived of oxygen during the exact moment when needed the most. I often tell students that if they hold their breath during a fight they will succumb to exhaustion four times faster than if they breathed during each exchange. The physiological reaction of holding your breath results in a sharper fighter’s curve and a quick entry into the chaos zone. When the muscles are starved of oxygen then exhaustion is accelerated and the body becomes paralyzed to attempt any counter attack.
• Experienced fighters learn to keep their eyes open even in the most fierce circumstances. Eyes need to stay open during an attack because the fighter has the best chance of survival if they see all strikes coming. Many knockouts occur because the opponent didn’t see the attack. If their eyes are open, then the body instinctively prepares for impact. Learning to keep your eyes open while being attacked help to create a shallow fighter’s curve.
• A fight is typically a cyclical series of exchanges: movement, exchange, separate, movement, exchange, separate, and repeat. These exchanges may be on the feet. Or on the ground where attacks involve breaking a limb or cutting off oxygen or blood to the brain. Once this happens then the opponent goes “to sleep” (Fight-speak meaning that the brain is deprived of oxygen resulting in the fighter going unconscious). A fight could very well finish on the first exchange.
• At the beginning of a match the fighter’s curve is zero. Throughout a fight the entropy level will never completely return to the same point as the beginning of a fight. This is due to the increased heart rate and less oxygen supplied to muscles as a fight progresses. Exhaustion also leads to a decrease in reaction time to an attack, as well as when attacking. Fear and panic also can contribute to preventing a return to low entropy. Strength, conditioning, technique, experience, and the fighter’s “heart” all help the fighter’s quick recovery to low entropy. Two fighters with equal talent and experience will be differentiated by “heart”. The fighter that has a higher determination to win will have the a psychological advantage.
• Furthermore, a fighter that keeps their cool in an exchange can capitalize on an opponent that has lost their senses (because they have transitioned into the chaos zone), and has begun to panic. Once an opponent enters their chaos zone, then they are the most vulnerable, and a quick finish could be imminent.
• Recovery from high entropy (or from the chaos zone), is for the exchange to finish so that the fighter can regroup and collect their senses. This returns the fighter’s curve to near their starting point and more importantly takes the fighter out of the chaos zone. The trick is to have a fighter’s curve that is gradual on the exchange and then sharp on the recovery. If the fighter feels comfortable during an exchange then they will remain technical in their offense and defense while simultaneously keeping their composure. Recovery from high entropy is quicker if the fighter is conditioned. If the fighter is not in shape then recovery to a lower controlled state is much slower as the heart rate struggles to return to normal and oxygen is replenished in the muscles. There is an added benefit for experienced fighters: Quick recovery to low entropy is more efficient since there is a much smaller recovery delta, when compared to an inexperienced fighter.

Gabriel Dusil has been a practitioner of Martial Arts for over twenty years. Originally he trained in the traditional style of Shotokan Karate. Gabriel has also trained under the expertise of Sensei Martin “Sonic” Langley in the United Kingdom. More recently he has focused on circuit training, conditioning, Brazilian jiu jitsu and kickboxing. Gabriel teaches both children and adults at the Ferus Fitness Fight Club, fffc.cz.

• During Christmas of 1965 I met Vašek. He was in his fifth year of university in the same veterinary program as myself. He had a great influence on my performance and always pressured me to do better. We studied together and went on dates as much as school permitted. The following year he graduated and then his compulsory military duty awaited him. Vašek and I got engaged in December of 1967 while still serving his military duties.
• Your father was an excellent surgeon. Taci was the best student in his class and the only one to finish with honors. For Vašek it was absolutely essential that he finished university with a red diploma. By the time he graduated, both of his brothers had finished their studies and also received red diplomas. The difference was that your father was the only one in his class that graduated with honors, whereas in engineering there were several students that completed that distinction.
• Taci was a great communicator and had a lot of charisma. Our clients liked him very much. He had an inherent view into the hearts of people, and that allowed him to be very compassionate and empathetic. Together we built a successful veterinary practice. He was ambitious and competitive, but not because he wanted to prove he was better than others – throughout his life his biggest competitor was himself, and the struggles he had with his own ego.
• Taci died 34 years ago today. We miss him tremendously.
• Maybe it’s because I’m an engineer at heart. Throughout my whole life I found beauty in numbers. When studying physics in university I got to a point in advanced mathematics where the line between science and art began to blur. I wanted to create this post to demonstrate how it is possible to find incredible symmetry in numbers, that are directly connected to those that we love the most.
• Our children are the light of our lives. They give meaning to our existence. There is nothing more important to me than Matias & Lucas. My boys are special, but I didn’t realize how extra special they were until I wrote down their birth dates for the first time. Here is a short video to Illustrate those two awesome days in my life.

• My mother, Valeria Kendeova, was the shining light in our family. I sometimes wonder where her strength and vision came from, since most of her life she suffered ill health. My mother contracted scoliosis as a teenager. This was due to malnourishment while attending private school in Budapest. When she came home for the summer holidays her mother noticed she had bowed legs, due to the onset of rickets. Valeria told her parents that she was always hungry at boarding school, but they didn’t believe her. Malnutrition at the school later manifested into scoliosis. The curvature of my mother’s spine worsened when she started to work as a clerk – sitting all day at a typewriter. The fact that my mother had a job was considered an achievement. Most women in post-war Czechoslovakia were homemakers. Valeria’s employment was further challenged by the fact that her Slovak wasn’t very good. Her mother tongue was Hungarian, and she also spoke German fluently. My mother also learned French while attending boarding school in Belgium. When the grandchildren were born my mother’s nickname became “Nanika”. This is from the Hungarian, “nagymama”, or grandmother. My mom was the one that guided me to getting a good education, and to strive for post-secondary studies. She allowed me to be independent.
• My father, Stefan Kende’s nickname was “Nadapi”, for the grandchildren. This was taken from the Hungarian “nagyapa”, or grandfather. My father wasn’t involved in nurturing me. Maybe it was different for my older brothers – Csaba who was twelve years my elder, and Attila was seven years older. Stefan had a reputation as an intellectual in our community. He worked as an antique book expert in Czechoslovakia – one of only three experts in the country, who would appraise old books throughout the state. This service was mainly for private libraries, collectors, and antique stores. My father was also a champion chess player – certainly one of the top ten best players in Czechoslovakia. Stefan would finish work at 18:00, come home for supper, then go to the café at Hotel Slovan to play chess. Nadapi played with a group of friends for one koruna per game (about five Canadian cents in today’s exchange rate). With their colorful game commentary they entertained onlookers. He also played in regional and national chess matches. He was a well known chess champion in Košice.

• Czech judo started in the 1930’s. Slovak judo started in 1954, in Bratislava, by Ing. Robert Binder. One year later, judo was established in Košice by Ladislav Magyar. In 1959 Mr. Magyar left and my dad, Vaclav (Vašek) Dusil, was elected to lead the judo “oddiel” of Lokomotíva Košice. The Dusil brothers continued to build on the foundations laid down by Ladislav Magyar. Judo in Košice had steady growth throughout the 1960’s, mainly due to the efforts of Lokomotíva Košice.
• Slovak men won very few medals in the 1950’s and 1960’s at the national level. The Czechs had a twenty year head start on the Slovaks, so the conditions to improve their skills were more developed. The bigger cities on the Czech side of the country meant more judokas, more and better training facilities & coaches and a higher level of competition. Women’s judo, on the other hand, started in the 1950’s in both Czech and Slovak parts of the country, so the gap in the skill levels was much smaller, if any. In the early 1960’s Bratislava dominated women’s judo on a national level. They captured around 50% of the all medals available (six in weight categories across junior and senior age categories, and one for open competition, where there are no weight restrictions).
• In the 1960’s the top countries at the European level were France, Germany, the Netherlands and later the Russians (who “converted” to judo from their version of Sambo, “Samozaschita Bez Oružija”, meaning “self-defense without a weapon”). Czechoslovakian judoka won a few silver and bronze medals in European championships from time to time. In the 2004 Olympic games, in Athens, Greece a Slovak judoka, Jozef Krnáč won an Olympic silver in the 66kg division.

• My dad and I were featured in the local Brampton, Ontario, Canada newspaper. I am photographed here at four years old “throwing” my dad with a Seoi-nage (背負い投げ, or shoulder throw). I vaguely remember this day. Training had finished, and the dojo was dark. We were at the entrance with the newspaper photographer. My dad jumped over me a few times, and it seemed that the photographer wasn’t satisfied. So my dad asked me to hold onto my arm as he jumped over me. And there we have it – a beautifully staged Seoi-nage!

• Having veterinarian parents carried an expectation that we would always surrounded by animals. Certainly that was the case – even at home. But it also seemed appropriate for my parents to go above and beyond that expectation. That’s why, when I was five years old, getting a Great Dane made sense. Even more appropriate was to call him by the nobles of names: Caesar (Named after Julius Caesar – although we used the Slovak spelling of Cezar).
• When we took him for walks on our street we always had neighbors approaching us, fascinated by his size. “Wow, he’s as big as a horse!”, was the most common comment. Back then many people had never seen a Great Dane in their life. During those years we were always known on the street as, “The veterinarians with the big great dane”.
• When we were young we would even ride Cezar. In the early days he was strong enough to hold me, but eventually only my sister was light enough for Cezar to hold her weight. Looking back, it may have seemed like a form of torture – parading on Cezar’s back as if we were riding a horse. Our friends watch us as if we were a act circus. At the time we felt that Cezar was relishing in the attention. Eventually we stopped our antics when it was clear he could no longer carry us.

• In December, I surprised my sister by coming home for Christmas. While in Burlington, Ontario, Canada I had the privilege to train with Alica at the local TapouT MMA gym, Tapoutburlington.com. This is the second of four workouts we had together. On this day we did some strength and conditioning, then we worked on a lot of sparing techniques, and had some fun with Jiu Jitsu. We also did loads of strength & conditioning with a lot of emphasis on core strength. Check out the video below.

• Our wedding was on the 24th of February 1968, and remember that it was a cold day. The first part was a civil wedding ceremony at the City Hall in Košice. From there we went to the big cathedral, Dóm svätej Alžbety. After the reception we went to my parent’s apartment on Krmanova 3. My father hired a cook to do the catering. Taci was responsible for getting the wine. Your father was still in the military at the time of the wedding. He chose his brother as his best man, just as his brother chose Taci when he got married. The wedding group was not very big – somewhere around twenty people. The wedding party included close family, friends and teammates from judo. It was a happy day. Today would have been our 47th anniversary.
• A year and a half later on 5th of September 1969 we left Czechoslovakia. We celebrated your first birthday in Paris, and you took your first steps there as well. We were there with your uncle’s family as well as your godparents, Slavo and Milica Sykorsky. We spent nine weeks in Paris, arranging for visas to enter Canada.
