There are no rules and on the count of three they just start kicking each other until one is standing and the other is down on the floor completely defeated and unable to get up.
There are many different things that would go into it- muscle mass, size, etc.
but assuming that both the male and female are of equal size and muscle mass, the female would win because females have more strength in their legs, while males have more strength in their torso
Girls
Me and my two older boy cousins took karate.I knocked them down in about 2 minutes.I also can kick some of my friends that are boys and cousins and even adults and girls and knock them down.
But that's cause I am the champion!
lol i guess it depends if you practice and are fit.
<--Man. If the girl goes first, she better get a good kick in because if it didn't take me out (which it probably wouldn't unless you were really strong) I would kick back so hard that it would send you back to last Tuesday.
Girls are taught to kick in self-defense from a very early age. We can even kick in high heels without losing our balance. Plus, one swift kick to the crotch is all it takes, at least for a bit...guys don't have that advantage.
Given all that, unless the guy gets a lucky shot to the head or just knocks the wind out of the girl, I'd have to say the girl.
Well... if they were about the same size, maybe the girl... girls are more flexible so they can kick higher, as in right in the face. Or she could just kick him in the groin.
ha-ha probably the guy because they have more leg muscle and can kick harder
but unless the guy is to wimpy and wants the girl to win then they are fools!
