I just recently saw a paper talking about how trained fighters can drastically increase the effective mass behind their punches by tightening their wrists, arms, shoulders and core (torso) when throwing blows. I've seen, however, most KE calculations on this site take into account only the mass of one's hand, maybe hand and forearm, when calculating the kinetic energy of a punch.
While an untrained fighter's punch will have only around 74~102% (avg 89%) their forearm+hand mass in effective mass, a trained fighter will have around 154~197% (avg 172%) the mass of hand+forearm in a strike. That's about two times the mass of a normal person's punch, so long as you have the correct training (and of course, speed also matters, since one can have literally the same body build and yet deliver a much faster punch. It's safe to assume that a trained fighter can have several times the strength of an untrained fighter, given the exact same body build).
So I'd like to ask... why do some pages from the wiki tend to use the mass of a punch as being the mass of someone's hand, when really it's ~90% the mass of hand and forearm in an untrained fighter, and ~170% that in a trained fighter?
BTW, in VSBattles stats, this means that given that a well trained boxer can punch at up to 9m/s peak speed (world record: 20m/s) and have up to 4kg of effective mass (couldn't find the world record for that, or even hand+forearm of the biggest superheavyweight fighter...), they could punch with 800 J of kinetic energy, which depends on having much greater effective mass than actual hand+forearm mass. A Peak Human such as Composite Human would definitely be many times stronger (especially if we were allowed to stack highest effective mass to mass ratio with highest forearm+hand mass with highest punching speed lmao)
