Combaton combines American football with 'martial arts'. It appears, from watching the videos and looking at their rules, that this means something similar to competitive Tae Kwon Do (TKD). Quick summary of how you can strike:
- Kicking is allowed above the hip, but not to the spine or back of the head
- Punching is allowed to anywhere on the torso, but not the head (no mention of if you have to use a fist or you can strike other ways as well)
- No grappling
- You can push as long as you followup with a kick
- No elbow strikes, but no rules on knee strikes
You score by kicking the goal pole (looks like a hanging baton):
A 3 point score is any standing kick (the support leg touching the ground). A 4 point kick is any jumping kick up to 180 degrees. A 5 point kick is a any 360 degree spinning kick.
Looks like the players all mostly wear the traditional TKD competitive vest with the red and blue spots on them under their football jerseys. The refs wear a gi-like uniform but with white and black referee colors (that's pretty corny).
I've never been a fan of TKD or football so this really isn't for me. High-kicking is generally a bad idea in most combative situations, however it actually makes some sense for a sport. I think it's certainly an interesting twist on sports. The rules at this time seem rather loose to me and I think if you got some serious players in the game (Muay Thai or MMA guys or anyone who knows what they're doing) it could get dangerous fast.
This will probably make it somewhere though because of the amount of interest in how TKD folks compete as well as in sports in general.
