But yet it takes a lot of time. It is much easier to Knock someone out without boxing gloves. It is probably easier to break your wrist if you are not trained to strike without boxing gloves. Without a glove, you can direct all your punching force on two of your knuckles, as opposed to the striking force being dissipated on a large area of the glove.
Wrestling perfects applying leverage on your head and limbs Jujitsu is adding restraint techniques using your clothes as well and choking. All these sports come from Human Fighting and at some point other strikes to soft pressure points and chokes were existed. It is much easier to crush someone’s testicles than try to break their arm, or much easier to gouge an eye, or pluck the windpipe from the close range.
But these Fighting Sports were not meant for people to kill each other. Instead they were meant to give an illusion of life and death confrontation to the average spectator, and to release the violence embedded in human nature in a controlled environment for the gain of money and fame. These fighting arts perfected many training aspects and drills to expose their athletes to the dangers of fighting sports and navigate a contest to a win. But the missing lethal elements were substituted for with fitness.
Inability to kill resulted in permitted manipulation of the fight using fitness, force, and building up resilience to impact. Developing agility to escape and attack their opponents in any angle possible which is permitted in the respective fighting sport was emphasized as well. Let’s say you take a champion athlete in fighting sports and teach him Pure Krav Maga. Will he manage to score much quicker under the constraints of his rules?
Assuming he already mastered any possible drill in motion and perfected the force and speed of his strike, throws and armbars, he might gain an advantage using Pure Krav Maga. Most of the stuff he might not be able to use in sports fight since he would probably get disqualified. But by being exposed to the hierarchy of possibilities and learning to prioritize and adjust using that criteria according to the distance, human body leverage and biomechanics applied in a tactical fighting view, and understanding the constraints of reaction time, and thorough understanding of pressure points and efficiency, it might put some order and drive in his training and results. It might make him a better sportsman as well and avoid an accidental death.
Some Fighting Athletes were and are great and worth a lot of admiration for their technical and physical skills. If you put two athletes like this on the same level you are getting a challenging fight. But most self defense scenarios lasted few split seconds. A single Punch death is something that is not unheard of. A single Knife stab as well, but even if a victim was stabbed 100 times; it was the first cut that had the “deepest” effect of distraction.
When Krav Maga was first spread, it was very common to see amateur boxers, Muay Thai, Jujitsu and Aikido students that won a national championship in a fighting sport or got a black belt in their non fighting art after very little training in Pure Krav Maga.
