 So-called "fighting" sports tend to operate under principles of using safe techniques, doing minimal harm, and consequently wearing down opponents and using other tactics supported by the "rules" of safe competition.In its role as self-defense and as a hand-to-hand combat system, Krav Maga operates under a completely different set of principles in which techniques may indeed cause significant damage and fights are to be ended as quickly as possible when the conflict cannot be avoided.Krav Maga organizations that involve competition are usually founded and named specifically to focus on using Krav Maga-based techniques specifically under a set of sporting principles.
