Just wanted to throw my 2 cents into the conversation.
The original poster is my sifu, so I am obviously a bit biased towards his teaching methods seeing as how I’ve stuck with him for almost 3 years now. Here’s how I feel about the no pads vs padded sparring.
I started out a few years ago into the martial art world with Tae Kwon Do. As you all know, you wear pads out the wazoo, but I still thought that some of the kicks were pretty powerful, and I definitely had the wind knocked out of me more than once. There was definitely stiffness, and my arms and legs were just as sore as they are today after a sparring session.
However, there is a huge difference between sparring with and without pads beyond the obvious. It’s not the bare fisted punches or the kicks that are necessarily all that different. Granted, it feels a hecuva lot more painful without any gear on, but the overall effect is actually quite similar. The major difference is in the little things. The shin to shin hits… the little sacred sword hand jabs… the rake of nails across the neck… These are the pains that you just don’t feel with gear on. Simply put, they are too subtle. But believe me, they can hurt like a sonofa*****, and I would absolutely hate to feel that kind of pain for the first time in an alleyway defending my life.
As it is, my first time sparring without gear saw me drop to my knees at least a half dozen times trying to either rub the pain out of my shin or trying to catch my breath. Now, after a few years, I barely notice them. Granted, there are still kicks that nail my sternum that send my breath into orbit, and I don’t think that’s something you can EVER truly get used to, but the little things that normally would send someone to the ground don’t phase me anymore. Or, at the very least, they don’t register on my face or in my body movements which can make all the difference in a fight.
So I do see the benefits of sparring with pads on. And I even see the benefits of at least sparring with headgear and a mouthpiece (there is a student in our class who’s a businessman and wears a mouthguard so he doesn’t hurt his image), but for me, it’s been extremely beneficial sparring with no gear. I have a lot more confidence knowing that I can handle pretty much any pain someone can dish out to me on the streets and still come out even-keeled. Pads made me feel like I was in a sport, not learning how to defend myself and loved ones to the death if need be. Maybe it’s because I’ve played hockey all my life, but I just associate pads with sport. They give you a false confidence because you FEEL like nothing will hurt. On the same token, I’ve played rugby for many years, and because you can wear NO equipment (not even a cup), I’ve learned that efficiency and accuracy are bred from realizing you are vulnerable.
In short, I honestly feel that you learn a lot more about defeding yourself by sparring with no pads, and better prepare yourself for fighting in the real world. Pads can be used as a tool (i.e. to practice sparring or perhaps to better develop certain kicks/punches), but I just don’t think padded sparring truly prepares you for the pain of real fighting, especially the little strikes that are just too subtle to be accurately done with pads on.
Okay… I guess that’s more like 4 cents… but it’s how I feel on the matter.
