A Krav Maga Vs Jiu Jitsu showdown could play out in a lot of different ways depending on the skills of the particular fighters, and the school of jiu jitsu involved. Both arts are based around military training but they are built for different eras. It’s also true that there are many different kinds of jiu jitsu training, and that really complicates the issue of deciding who would win a Krav Maga Vs Jiu Jitsu contest.
In a very basic sense, there are two general types of jiu jitsu. One is a Japanese military fighting system from the times of the samurai, and it includes a wide range of techniques, from strikes, to throws, joint locks, and even pressure point attacks. These days, when most people talk about jiu jitsu, they are usually thinking of Brazilian jiu jitsu, which is designed around no-holds-barred fighting events, and focuses much more on ground fighting.
Krav Maga is a system designed for the Israeli military and it’s built with techniques from karate, judo, and many other fighting approaches. Krav Maga practitioners are focused on being proficient in a street confrontation, and capable of dealing with survival situations. It actually has more in common with traditional jiu jitsu than it does with Brazilian jiu jitsu.
In Krav Maga Vs Jiu Jitsu fight, there would probably be an advantage for a Brazilian jiu jitsu practitioner. This is because they generally spend a lot more time sparring than Krav Maga fighters, and many of them are training to be competitive in sporting events, which requires tremendous athleticism. On the other hand, this kind of fight could also end up the other way if the Krav fighter relied on some of his more brutal techniques such as eye gouges. Brazilian fighters are very reliant on ground techniques, which can be dangerous in some street situations, and the Krav Maga fighter might have the right skills to take advantage of that.
If it was a Krav Maga Vs Jiu Jitsu fight involving a traditional Jiu Jitsu practitioner, it would probably be an even contest, and the winner would really depend more on the natural talent of each fighter. Generally, Krav Maga is a little more focused on striking techniques, while Jiu Jitsu has a bigger focus on grappling techniques, so the winner would probably be the fighter that most effectively imposed his advantages.
