There are several different types of Jiu Jitsu available. Brazilian Jiu Jitsu is a type of self-defence sport. It primarily involves grappling, and chokeholds. The sport has been around in various forms for some time. It is derived from Kokodan Jud Jitsu. Brazilian Jiu Jitsu is simply a form of this martial arts self-defense technique. The purpose of this sport is to show that a smaller weaker person can prevail against a larger stronger opponent by using a variety of chokeholds, and leverage techniques to throw the larger opponent off balance. It is a valid martial arts technique. There are a variety of competition and performance techniques that allow individuals to work through different ranks of the system.
Some of the practitioners use a combination of competitive sports and yoga. Yoga has a place in competitive sports and allows the individual to obtain maximum flexibility. There are many yoga techniques that an individual can use to help with Jiu Jitsu or any competitive sport. Certain yoga moves combat sports related injuries like hamstring injuries and the like. The theory is that competitive sports make athletes prone to injury because they are one side dominant. They create a symmetry in the body. Yoga will allow the individuals body to maintain its natural symmetry.
Some practitioners of Brazilian Jiu Jitsu (or BJJ) believe in using yoga to maintain harmony with their surroundings. Jiu Jitsu is a Japanese martial art originally, and the practitioners of this art strive to maintain mind, body harmony. It is something that the sport is based on. Yoga especially Power Yoga is a good thing for sports practitioners to use who need to maintain their body and physical fitness.
It just makes sense that a form of martial arts that originated in the orient would make use of yoga techniques, and other exercises such as Qi Gong, since being in harmony with body, and nature goes hand in hand with the martial arts philosophy. It is a great thing to be able to use both of them in conjunction.
Brazilian Jiu Jitsu uses both mind and body to be able to control an opponent, and gain submission over them. Using Yoga techniques may help the participants to gain control of their body and mind, and may also help them use breathing and mind techniques to possibly help them subdue an opponent, and get control over them. Yoga classes may also help the combatants understand the Asian nature and philosophy of combat.
