2. Muay Thai
Muay Thai has often been referred to as Thai boxing, but it’s much more than that. In Muay Thai, competitors use kicks, elbow strikes, and even knee thrusts in addition to the regular punches that you’d see in boxing. You might think that this makes a boxer’s fracture less common in the sport since there are fewer punches being thrown but it’s actually quite the opposite.
There are numerous occasions where an elbow strike could intercept a punch and put a large amount of force on the metacarpal. When you factor in the repetitive stress that the metacarpal of fighters endures during training then it should come as no surprise that these elbow intercepts lead to a boxer’s fracture. The boxing glove is also rather ineffective at defending against elbow strikes since there’s a small point on the human elbow making it more like a knife than a hammer.
