give two or three nut kicks to some dudes
It will not work such way. If ou managed kick one - two guys such a way, others will be aware.
Also, despite wide assumptions that it is easily doable, it isn't easy on experienced guys.
They are aware about nuts and bladder, also if raised high guard, will immediately start beat and kick not waiting anything.
These still are wulnerable to leg kicks, avoid them is Harder than nuts kicks.
Still, yes, if landed, they will work, but not always that hard than expected.
Actually points does more than pain ( in high adrenaline pain sense if FAR lower ).
Wirsts grips in proper places can cause fingers feel like dead wood, strong kick make leg feel like from wood ( with shoes or boots far more effective if landed ). Why this, better to ask neurologist ( doctor ). Actually if he had some combat traiing, is really capable to TKO guy who grabbed his clothing on the same level with both hands…. Apply any pressure type stuff on mobile opponent is damn hard. Precisity is required far more than properly hit chin ( none of superstars celebrities did even it with all attempts ) so hard to dream.
Not mobile object, of course different story.
it probably wouldn't work is if you don't get kicked
Actually to be aware from these kicks/ punches exactly is taught for self defense ( doesn't matters what name of styles for selling ) and sadly, dirty street thugs that kicks others in balls are aware too….
So yes, It is effective but nobody should base his training/ defense ideology only on this stuff.
Like eye pokes, throat strikes ( if one doesn't have nuts to hit face with fist, we can't expect that he will be able to pull trigger! And to poke eyes, smash throats requires not less nuts, even more than pull trigger ).
If one is able to hit head with fist in sparring, after already had be hit few times, he does have far more chances to do successfull eye pokes etc.
