It's all traditional. All the ways to kick, punch, throw, lock....these have been around for a long time. Maybe some forgotten and rediscovered and given funky names like Rubber Guard or X Guard. There's nothing new.
At least from my perspective, when I hear "Traditional Chinese Martial Arts" I think of white kids in Chinese uniforms practicing Kung Fu forms, some non-too-intense line drills, fake weaponry and some lion dancing to earn sifu extra cash around Chinese New Years and weddings. I think of deep horse stances with iron ring adorned forearms. I think of wooden dummies and jow. Iron Palm. Dim Mak. And many animal styles.... unfortunately I also think of posers, non fighters, dreamers, defensive insecurity based on later.
When I think of "MMA" or "Sport Combat" I think of sweat soaked men collapsing and sitting back against wall-to-wall padding after live rolling or sparring.... which took place after live drilling. After intense physical training.... I think of black eyes, bloody noses, jammed fingers and toes. I think about preparing oneself or team mates for an upcoming match. About pushing myself further than when I want to quit because that's what establishes one's reputation.... not belts, or years or if you take sifu to dinner. I think about what it's like to set an appointment to fight someone in 3 months. Knowing there is someone out there training specifically to hurt you. And hurt you bad and fast. I think about sitting backstage in a locker room and hearing the crowd roar and know someone just got slammed or KOed and I'm up next. About entering the cage to fight and having to step over the pool of blood collecting in the corner from previous fights.
There's a difference between "TCMA" and "MMA". Not saying one is better than the other... that depends on one's goals. Though I will say training MMA is preparing for the now. Working and training and fighting now, not preparing for an unknown encounter sometime off in the future. It's very alive. Which is why I prefer it now. I don't always agree with approaches or techniques... I keep my mouth shut and do what the coach says when drilling. Then there's live free play. You can incorporate anything you want then. I prefer this to training an ideal technique without live interaction/testing/proving.
