This question has been bugging me for awhile, and it mainly comes out of Rickson Gracie's arguments in regards to self defense BJJ vs Sport Bjj, and the age old Martial Art vs Martial Sport debate. When I think about what a martial sport can bring to a table vs a martial art, I simply have to give the edge to the sport. They develop speed, cardio, strength, and are applying their skills over and over again in a controlled environment. MMA is a sport that is currently giving traditional arts a run for their money. Their exponents just appear to be better fighters overall than their traditional peers. People constantly say that Boxing is great for self defense, and Boxing is definitely a sport at just about every level of practice. Here is vid of a sport Bjj practitioner in a fight on a basketball court: While he was consistently interrupted by bystanders, he still executed his moves well, and clearly controlled his opponent at every stage of the fight. Anyway, I'd be interested to hear what others think about this.
