They're clearly not fighting and not even trying to make it look real.
If your brain ever manages to gain enough intelligence to enable you to 'read' you will then be able to read and see that it's a Bra & Panties Match (Strip-Wrestling Match), so by which to win one girl needs to STRIP her opponent naked.
You don't win these matches by 'fighting and beating-up your opponent', you win by stripping your opponent.
Hence why these girls are focused more on trying to strip & humiliate their opponent.
You want fighting & attacking go watch female boxing or womens MMA.
