Exactly what are the purpose of gloves in combat sports? A common misconception that the general public seems to believe in is that gloves are for protecting the opponent. However, it does not protect the opponent, but instead protects the hands. What it does do is it makes the force transfer over a greater surface area. This makes a blow more concussive than penetrative. More brain damage but less bone damage, while also lowering chance of KO.
Small gloves and large gloves for both dangerous in their own right. Purpose the most dangerous for short term matches are thin gloves that do not add surface area but acts to protect the hands a bit.
