Kickboxer broke his leg?

Question

I recently visited the popular internet video of the kickboxer who kicked the other boxer and broke his leg. I'm really curious as to how that happened, and is that even possible? Can anyone explain the physics of that?

Answer 1

I hate that video. Kickboxer attempts a low outside leg kick. His opponent leg checks the kick and kickboxer ends up kicking his opponents knee which breaks the kickboxers shin.

Answer 2

how technical  do you want me to get with the physics? every action has an equil and opposite reaction. guy one throws a kick. guy two checks kick. guy ones leg is moving at such a speed. guy two leg is not moving. knee is thicker than the shin and stationary. also the shin is stronger running up and down not side to side. the momentum created by the kick was greater than what the shin could take but less than what the opponents knee or top of shin could take.

Answer 3

i cant explain the physics of that but it is possible happen to me before hurts relly bad

Answer 4

He made a mistake

Answer 5

I'm not a physics guru or claim to be a master anything but I teach a little stand up to MMA beginners. One thing I focus on getting accross is the idea of velocity times mass equals force and in muay thai the force is always going to go somewhere on impact. A properlt thrown muay thai roundhouse kick impacts at the hard shin surface not the feet. The round house kick generates an often highly underrated amount of energy that normally smashes soft tissues and sends shock tremors through bone causing several small hairline fractures. This mainly because the shin bone has a bigger mass and is a much harder material than its target. The smaller target cannot distribute the huge amount of force evenly and becomes damaged. When the shin strikes the knee, the force is distributed throughout the patella, femur, and knee structures so the force does not collapse any material so the shock wave rebounds back into the shin. A Kick boxer often has already many microfractures in their own shins (because of competition or training) and they spread and greatly increase in size when the knee block sends the power of the kick back through the shin. This causes the microfractures to explode and result: broken tibia.

I always guessed his leg was broken in the past and it was an old injury coming back to haunt him
