In the 2118 Olympics held in space, what combat technique would be the most effective in a weightless ring (?sphere). Personally, I would bet on an octopus...

What do you think?

Float like a butterfly, sting like a bee. This is true aerial combat.

The combatants would be tethered together. Their fighting skills would be developed to work within those restraints. Their motion would then be determined in part by the motion of their enemy combatant.

I would imagine the sport would resemble wrestling or jujitsu more than boxing or kickboxing for the simple reason that there would be no ground to push off of to deliver punches and kicks. One could imagine a 3-D network of ropes or poles that the opponents could grasp and maneuver with as they fight, or as PmbPhy suggests, just tie them together!

If there were a large, air-filled volume with microgravity, I expect they would wear wings, and fight it out like eagles on Earth.
