for the edification of others
The other day at the dojo, our sensei had us punching bare-handed against bags (the flat pad type that another person holds onto). I wound up punching mine a few more times with a little more force than was strictly wise — because of course I did; I’m a writer and I was curious to see what it felt like, and I’m unlikely to go around getting into fist-fights just for research.
Since my hand is still complaining at me a little bit today, I figure I should share what I learned with others, so they don’t have to do the same thing. 🙂
The actual impact stung a fair bit, and increasingly so as time went on, of course. But I was good about keeping my wrist straight, so the impact went up my forearm in a direct line; you can really mess yourself up if your wrist isn’t straight, because then it will buckle under the impact and you’ll probably sprain something. (And I really do mean straight. Mostly straight = not good enough.) My knuckles turned visibly red, and I got a small mark in the webbing between my ring and pinky finger, like I’d chafed the skin or something. Fortunately I didn’t persist to the point of really doing myself a mischief, because near the end I subconsciously flinched from the sting of impact; my wrist buckled, but there wasn’t enough force in the punch for that to do any damage, and then after that everything I threw was complete crap. I imagine that adrenaline would have carried me much further in a real fight, but odds are good that it would also have made me more likely to use bad form and hurt myself that way.
My knuckles stayed faintly red for the rest of the night, but were back to normal the next day, and the mark faded about as quickly. The lingering effect is in the soft tissue between my metacarpals: I still feel an intermittent ache there, and if I use my left hand to shift those bones around, I can tell there’s tension and stiffness. So the moral of this story, I think, is that if you’re going to talk about punches leaving a mark on the one who threw them (and you should, unless your character is a hardened bare-handed brawler), the problem isn’t so much in the knuckles as in the hand itself. Or the wrist, if they threw a stupid punch and sprained something. Or, y’know, all over the place if they were really dumb and dislocated a finger or broke a bone. But the palm of the hand is going to take a beating even if nothing more severe happens elsewhere.
So now you know. And don’t have to pound your own hands to find out.
