The typical punching force of most people lies between 60 and 170 PSI, with outliers at both extremities of that range. There is considerable disagreement over how much training may add to a person's punching talent vs genetic tendency. Most experts agree that genetics plays a large role in one's natural ability to strike hard.
When you throw a punch, the human body uses energy from two sources: ATP (adenosine triphosphate) and oxygen. The harder you punch, the more ATP and oxygen your body consumes. After some punches, your body will need to replenish its supply of these nutrients by eating glucose and oxygenated blood. This is why it is important not to punch hard if you are low on energy molecules.
The maximum effective punch depends on several factors such as weight, speed, and distance. If one adjusts for these variables, it can be shown that the total energy delivered by an average puncher is about 100 joules (92 foot-pounds). This exceeds the average peak power of a good kickboxer but is less than the highest recorded power in boxing (about 115 joules). Therefore, an average person can deliver enough energy to cause significant injury if they hit you with their fist.
Hardness is only part of the equation. You also need to consider where you hit your opponent with the fist.
The average untrained individual can throw a punch with a pressure range of 60-85 PSI (pounds per square inch). A trained striker, on the other hand, can create far greater force. They strike between 194 and 336 PSI.
They have a pressure range of 194 to 336 PSI. That's more than twice as much pressure as an average person can generate!
The maximum pressure that can be generated by a human fist is about 500 PSI. Some scientists believe that actual recorded punches reach up to 5500 PSI! This is called hyper-peak pressure and it can cause serious damage to bones, blood vessels, and organs.
Hyper-peak pressures can be achieved in three ways: 1 through intense concentration on the part of the fighter; 2 by using certain techniques, such as makiwara (see below), that produce higher pressures than ordinary punches; or 3 by punching hard objects, such as rock surfaces, wooden boards, or metal cages.
The intensity of emotional feeling involved in combat sports helps the athletes achieve these high pressures. These feelings are called "rage" and they often lead fighters to engage in dangerous behavior, such as hitting the head against heavy objects during fights.
In science labs around the world, researchers use pneumatic guns to test the strength of fists. They find that men can generate forces up to 250 pounds at just over one foot away from their bodies.
A study of 70 boxers discovered that elite-level competitors could punch with an average force of 776 pounds. Another study of 23 boxers found that expert fighters could strike twice as hard as amateurs, with the strongest hitter generating over 1,300 pounds of force. These results were published in 1996 in the journal Medicine Science Sports Exercise.
The human head is the most vulnerable part of the body when hitting someone with a fist. Because of this, people who fight often practice headbutts and kicks without even noticing it. Over time, this will give your body ways to protect itself from these kinds of attacks.
Your skull is quite stiff to begin with, which means that when something hits you on the head, it has a lot of energy. To be able to absorb some of this energy by bending your arm instead of your neck, your bone structure needs to be right. And since boxing is all about delivering powerful blows, this kind of training is very important.
These results suggest that a pro boxer can inflict serious damage with his fists.
An average male boxer is about 200 pounds and stands 5 feet 11 inches tall. He will have a body weight of about 125 to 150 pounds. It is expected that he will train hard for about 15 hours a week for several months before a fight. His hands and arms will be strong after this period of time.
During a boxing match, the boxer who lands the most effective punches will usually win. Effective punching techniques include left hooks, right crosses, uppercuts, and jabs. Different combinations of these moves can be used to deal different types of damage against an opponent. For example, a sharp left hook followed by a right cross would be a good technique for someone who wants to score points but not cause much injury to their opponent.
Top-level boxers often use their fists to subdue their opponents before applying other forms of attack, such as kicks or punches from behind. For example, a boxer might use his fists to knock out his opponent so that he can take him to the ground where he can apply more effective strikes.
Ivan Drago punched at roughly 2000 psi, according to Rocky 4. Drago's representative in the film portrayed the "average" HW as striking with about 700 psi to put Drago's unusual punching strength into context. In other words, Drago was nearly three times as strong as the typical HW punch for punch.
Hagler used about 1500 psi to knock out Sonny Liston in his corner. This makes him about twice as strong as the average HW. But this doesn't take into account other factors such as weight class or style of fighting so this estimate is very rough.
The average male boxer is around 150 pounds and wears 35-40 pounds of clothing so we'll use those figures as our baseline for needed pressure. A single punch by itself usually only produces peak pressures of around 15-20 thousand psi but multiple punches by a strong person can produce peaks over 100,000 psi! That's hundreds of times more than the force of gravity acting on a body mass of 75 kg (165 lbs).
So even though a single punch by itself isn't likely to cause damage, the combination of many weak punches can be very powerful. And since men are generally stronger than women, this number may be higher for males as a whole.
The amount of force a person can exert is determined by a number of factors, including the individual's mass, the acceleration employed to produce the force, and the friction, gravity, and other forces at work. Researchers discovered that boxers' blows may create up to 5,000 newtons, according to Live Science...
Newton is the unit of force. It is equal to the force exerted by one kilogram (kg) on a point at a distance of 1 m from its center of mass. Thus, 1 Newton is equal to 0.98 Newtons per kg or 9.8 Newtons per kilogram (kg).
According to Dr. John Staughton of Oregon State University, people can exert up to 200 newtons (10 pounds) of force with their hands and arms alone. This limit includes the weight of the arm and the degree of muscle contraction necessary to generate a given force.
In reality, people are able to exert more force than this estimate suggests for two reasons. First, as noted above, people can lift more than 10 pounds with their arms alone. Second, the maximum possible force that can be applied to an object is not always needed to achieve a given result. For example, if someone can push against a resisting force of 100 Newtons but cannot pull against a force of 10 Newtons, it does not matter how much force they apply with their hand or arm because they will never be able to move the object.
