Three factors that affect the power of punching
In the last issue, the technical principle of punching action was analyzed, and this issue continues to describe the three factors that affect the power of punching.
In training, the factors that affect the power of punching should also include the following aspects:
(1) The relationship between punching speed and strength.
In various sports, the human body has two forms of force: dynamic and static force, and dynamic force refers to the ability to use force in the entire range of motion (the length of muscle contraction is obvious); Static force refers to the ability to use force without displacement throughout the movement (the increase in muscle tone is evident).
The dynamic force can be divided into weight and speed force, according to the form of punching action, the form of punching can be speed force; The horse step pile action is obviously a static force.
In boxing techniques, it is usually required that the punching force should have “inch strength” or “soft and rigid”.
The so-called “rigid” means that the impact force of the fist has the characteristics of rapid and sudden force, and this sudden rapid force action is explosive, so it is also called “explosive force”.
Explosive power = speed × power.
Therefore, when the punch movement moves, the muscle contraction speed is different, and the force (power) generated is not the same. It is not difficult to see that increasing the power of punches and increasing the speed of punches can produce explosive power.
It can be seen that training to improve the speed of punching is an important way to increase the power (inch) of punching movements.
(2) Offensive and defensive consciousness can control the power of the fist.
In martial arts theory, it is proposed that “consciousness governs the power of the fist”, and the so-called consciousness refers to the thinking activities of the central nervous system of the human brain. In peacetime training and actual combat, mental state can directly affect the power of boxing.
Studies in exercise physiology have proven that:
“If the frequency and intensity of nerve impulses coming out of the central nervous system are high, the force generated by the muscles is also greater.”
Therefore, when training, it is necessary to pay full attention, establish the enemy situation, and have a sense of combat attack and defense; In actual combat, we must have the confidence of victory and fight the enemy to the end with a mighty and unyielding fighting spirit. This can clearly promote the power of the punching action.
(3) The breath matches the punching force.
Punching with exhalation (vocalization) at the same time has a certain auxiliary effect on the force of punching movements. The method is to exhale short gases while hitting the opponent hard with the punching action, so as to achieve the effect of “urging force with qi”. This phenomenon of exhalation (vocalization) combined with boxing techniques is particularly evident in highly confrontational karate, judo, wrestling, boxing, martial arts, etc., in addition, through “vocalization” can not only accelerate muscle contraction, enhance strength, but also play a special role in tactics of “winning people with sound”.
The three aspects mentioned above are the relevant factors that enhance the power of punching, and the relationship between punching power and speed is closely coordinated and complementary. Without speed, there is no power; Without studying strength, speed cannot be discussed, and as for improving all techniques (fast, heavy, accurate, variable and dense) of punching, the content is very extensive and should also be included in the scope of systematic training.
