Take a look at one of your limbs and straighten it as much as you can. Notice that your elbows and knees each have a clearly defined limit of rotation – these are called “joint limits”. While you might not think about them much, Brazilian Jiu Jitsu fighters see our joint limits as exploitable weaknesses. Martial artists have been inventing and refining ways to hyperextend their opponents’ joints for hundreds (if not thousands) of years. These “joint submissions” are executed by acting as human levers or torque wrenches, trying to rotate joints past their limits.

Does Boxing Headgear Prevent Concussions?
In boxing, behind every punch connecting and glove pushing into a face, there is a complex collection of engineering principles at play that can vibrate a human skull and cause serious neurological damage. The impact of a punch can jolt the brain, causing it to move across the cerebrospinal fluid that it sits in and putting the person at risk. The rotation and rebound of the brain inside the skull from the rapid force applied is what produces concussions in the sport. Theoretically, headgear will reduce the likelihood of a concussion by softening the blows.

If you have seen the 1984 film “Karate Kid”, you know that the only way the protagonist Daniel LaRusso was able to defeat his nemesis Johnny Lawrence was with a “crane kick” to the chin powerful enough to knock him down allowing Daniel to clench the title of the Karate tournament.

We have all seen it before, whether it is in Hollywood depictions, or watching competitors in the Ultimate Fighting Championship, there is always a sense of awe when watching humans strike and break surfaces with astounding force. Whether it is breaking bricks, a baseball bat or their opponents, the physiological phenomena that allows these athletes to perform such feats results from years of dedicated practice and study. By continuously placing their bodies under immense stresses and impacts, the actual composition and density of the athlete’s bones adapt to provide increased strength and durability. In practice this is done by repetitively striking a hard surface, such as a wooden planks, or a punching bad, with increasing force for a prolonged period of time. Although the practice of bone hardening has roots as ancient as the martial arts themselves, the scientific study of the phenomena has only occurred in the past few decades. So how do these athletes develop exceptionally strong bones?

Every sport has a different “ideal” body type, which is largely dictated by the muscle groups it focuses on training. Swimmers prioritize developing the muscles in their shoulders and backs, which allows them to propel themselves through the water with their arms. On the other hand, runners prioritize the hamstrings and quads in their legs, which allows them to generate greater force when pushing off of the ground. So, what is the ideal body type for boxing? Strength is clearly important when punching an opponent, but is it even the most important factor in boxing performance? Should either upper- or lower-body strength be prioritized over the other?

You and I are living creatures. Every living creature on Earth has some means of self-preservation, and while society and technology have advanced humans far beyond the norms of the animal kingdom, deep down at our core is the self-preserving instinct known as “fight or flight”. When the moment arises that flight is not possible, that unarmed self-defense is the only option, a human will most likely throw a punch. Unless you are trained in a combat sport or a style of self-defense, that punch will likely be inefficient and ineffective. I’m here to break down, with biomechanics, the most effective way to throw that punch.

Our brains are made of a very soft material but luckily our skulls provide the brain protection from the outside world. However, during violent movements the brain is free to move inside the skull and collide with the skull. This impact can cause injury to the brain, known as a concussion, that can lead to various symptoms depending on severity.
