José Aldo in the context of World Extreme Cagefighting

Luta Livre (Portuguese: [ˈlutɐ ˈlivɾi], lit. freestyle fighting or wrestling), known in Brazil as Luta Livre Brasileira (lit. Brazilian freestyle fighting) or Luta Livre Submission, and also Brazilian Submission Wrestling, is a Brazilian martial arts and combat sport created by Euclydes Hatem in Rio de Janeiro. Primarily a mixture of catch wrestling and kosen judo, there is also ground striking with the hands, feet, knees and elbows. Notable practitioners include Marco Ruas, Ebenezer Fontes Braga, Johil de Oliveira, Alexandre Franca Nogueira, Renato Sobral, Gesias Cavalcante, Pedro Rizzo, Darren Till and José Aldo.

There are two styles: esportiva ("sporting") and combate ("ground strikes"); both styles are no-gi. In esportiva competitions, grappling techniques are the only techniques allowed to subdue the opponent. Another style developed later is called "Luta Livre Vale Tudo", which is similar to the modern MMA style which allows both standing and ground strikes and submissions. Consequently, it is important to calmly strategize and execute moves with the aim to force the opponent to submit via armlock, leglock, choke or necklock, or to win by points (i.e. takedowns, domination position). Punches, kicks and other "hard" techniques are not allowed as this is considered more a sport than actual combat. Combate, on the other hand, includes striking techniques on the ground; palm strikes and kicks are allowed, but the ground fight and submissions are still the largest elements. This is also the form used in MMA-style fights.
