so to say that elbows are more powerful is absolutley absurd. The range is just in a completely different class...plain old physics man
Actually... The generation of force within an elbow or knee strike is higher than that of a punch or kick. However, the surface area that the force transfers through is much
bigger in an elbow or knee. Where a punch would be a whip or spear, the elbow is your club. It's the same reason why a low velocity round being shot out of a gun will pierce flesh and cause internal trauma, but a beabag shot out of a 12-gauge will cause surface trauma and not carry the same amount of "lethalness." The surface area of the fist is smaller than that of the elbow and transfers the force better.
I can see where northcoastmma's coach is coming from. In a full-range stand-up contest, elbows shine in the limited confines of the clinch. Statistically speaking, most KOs in MT matches come from Punches followed by High Kicks.
Now in MMA, because of the clinch and also ground fighting, elbows are probably more effective than punches simply for the fact that you do not need a greater amount of distance to create force on the elbow. So in that regards, the elbow is golden in application.
Now the reason why cuts are so prevalent with elbows is because you are not required to pad your elbows. If your hit an elbow correctly, you would be hitting with the point of the elbow instead of lower on your forearm. In which case, connecting to the orbital area or other bony areas of the face will cause cuts very easily as the skin is pressured between 2 sharp objects causing it to split open. The same thing is possible off of a punch, but is not as likely due to the fact that the glove disperses some of the direct force.
