Bio mechanics of Boxing
Newtons First Law
Newtons first law of motion refers to every object being at rest unless an unbalanced force is applied to the object. This law is applied to boxing as a fighter will stand in a balanced state until an external force (such as a punch from another fighter) is applied. At the point of contact, the fighter who is punched will be knocked "off balance" and body parts such as the head, neck, chest, torso, ect... will be moved.
Basically a fighter will not be moved until an external force (Punch) moves him/her or uses his own force to move him/herself and vice versa.
Newtons second law
Newton's second law states that the amount of force that is exerted by an object is determined by the acceleration and mass of the object (F= M x A).
This is applied in boxing in which the amount of force that a boxer can exert out of a punch is determined by his/her weight multiplied by the acceleration speed of the fist that is throwing the punch.
Basically the larger and quicker a boxer is, the more ability to exert more force out of a punch.

Newtons third law
Newton's third law states: "with every action, there is an equal and opposite reaction."
This is applied in boxing with Momentum in which if a fighter were to get punched, he/she would move from the spot of exerted force in the direction of the punch.
Basically if a fighter were to punch an opponent to the left, then the opposing fighter would be moved to the left.
Levers
First, second and third class levers such as the head/neck, leg/feet, and the arm/ elbow are very important aspects of the human body that can make a difference in a fight.
Fighters must be able to bop/tilt their heads around to avoid the head shots of opponents.
Fighters must stay light and balanced on their feet (typically the balls of the feet) to dodge, move and hit their opponent within the ring.
Fighters flex/extend their elbow in order to exert punches, which is an entire aspect to the sport its self.
1st principle- Stay low but keep your head up while your body is moved inward and towards the center line of your base. Feet should be wide apart and legs bent in order have a large base. Gain more wieght or muscle mass. This is to have increased stability.
2nd Principle- Increasing max force can be done through weightlifting and training of the fast twitch muscles and joints in the body. (professional trainer should be acquired)
7 Principles of Bio mechanics : tips/ advice for boxing
3rd principle- The use of all joints in order to reach maximum velocity is required. Weightlifting and professional direction from a trainer should be advised in order to improve strength of muscles and joints in the body.
4th principle- The greater the impulse, the greater the velocity will be. Same direction of the last 2 principles should be followed. Also, mental mindets of quickness and agility should be set in.
5th principle- A fighter should always keep his head up and protected to know his sense of direction as well as train more to be able to exert out more force in a certain direction.
6th Principle- Training that helps someone stay low, keep equilibrium, and stay centered should be advised as angular movement increases the closer the external force (punch) is to the axis.
7th principle-Training involving the quickness of landed punches and avoiding hits should be advised. This is to avoid your arms being "free" for too long after a punch is landed. Avoiding hits means avoiding free falling in air when there is angular momentum.
Perfecting techniques/ tips
Footwork is very important and should be trained daily
Constant movement in the ring to keep your opponent "on his toes"
Distance control
Stay heavy (F=MA)
Quick landing punches
Turn whole body when punching
Equipment used inside/outside the ring
Sparring boxing gloves
