What determines if you have one punch knockout power? How come some fighters have it, while others don't?

Some fighters in UFC have one punch knockout power, while others don't. Why is this? Is it a physiological thing (the length and proportion of your arms, the thickness of your wrists, etc.) - in other words, genetics? Or, is it how you're trained?|||It is a combination of factors that lead to a one punch KO. It has much to do about where you were able to strike, how the opponent takes the punch, how hard it was thrown, if the person has been KO'd before, is tired, ect.





Some guys in the UFC are insanely strong, but it is also the technique they have been practicing many times before, which they have perfected to get maximum torque with speed after a set-up.|||One punch knockout power is all about timing, precision, and the technical application of strength. Brock Lesnar put an unbelievable amount of strength into the straight right that bowled Heath Herring over, but it didn't knock him out. Dan Hardy appeared to have barely tapped Rory Markham, and the lights went out. You have to hit the right spot and the right time with the right balance of speed and power, and to do that consistently requires a butt load of training and practice, which is why some have it, and some don't.|||Knock out power comes from technique and accuracy. someone who punches without a good technique and still hits someone on the chin will not be as efficient as someone who punches with a good technique and hits the chin,, there are other body knock outs.. though rare, but the chin is usually the spot you want to hit to achieve a knock out. but we aren't really talking about the opponent here, yes some opponents will be more apt to get knocked out than others, but the power comes from your technique.|||It's a little about whether you can take a hit, but most knockouts will occur when the attacker gets a good hit in a good position. Sometimes its luck, but not likely. No matter how much damage a person can take, if they get hit in a sweet spot they are going down, but hitting them there with accuracy force and speed is the hard part. Most the time they dodge or their hands get in the way.|||Size and Speed play a big part. If your too big in size then you won't hit as hard because your punch will be travelling slower. But if your a good size and good speed, that produces some real hard punches. But some other things that count towards KO power are just the strength of the man, the technique, you need accuracy otherwise your not gonna get a KO unless your a lucky shot.|||it really depends on who you are fighting. i got kicked full force in the head by someone who constantly finds them self knocking their opponents out, the judge even stopped the match to make sure i was alright, but i was completely fine and ended up winning the match. its really more about the persons ability to take a hit rather than the person who throws it.|||What the guy above said, basically its the training.|||well punch someone really hard and if they get knocked out u have knockout power.
