Nicole Chua of Singapore trains at a gym in Singapore March 28, 2012. While abhorred by its critics as a celebration of violence, mixed martial arts (MMA)'s explosive growth shows no signs of tapering off. It does not shy away from its violent image but rather embraces it as the ultimate sporting evolution of hand-to-hand combat. Some 8,000 fans watched Chua become the city-state's first female professional MMA fighter with her debut as part of ONE Fighting Championship's recent "War of the Lions" event.
