Backspin is the most powerful leg technique in taekwondo.
That's a collection of several forces.
First of all, it is similar to the feeling of force in the ankle when slashing, and the side hook kick is also used. It's the power of the explosion. Of course, it is better to use the heel, it is generally better to use the forefoot.
Then there's the power of rotation, mainly the waist strength.
In fact, there is also the amount of ground that kicks the ground, not kicking the ground, but the moment it hits, the supporting feet also exert force. This is similar to a back-slip kick on a counter-attack. In the process of kicking, the supporting foot is not very strong, but the moment it hits, it must be powerful.
Is your side hook kick powerful? A good player can knock out an opponent with a side hook kick. The back kick can be seen as a turn and a side hook kick, which is of course much more powerful.
The force of the body rotation and the power of the ankle explosion are to hit out the moment you touch the opponent, and at that moment your foot actually has a small acceleration, and this is a small deceleration of the body.
Imagine how far you would throw a gun on a high-speed train. Your spinning body is the train, and your sidehook-like foot is the javelin. The moment you touch the other person is the moment you shoot the javelin.
1+1, it's not just 2, it's physics, destructive force and speed are not proportional, that's the square relationship!

Our coach has seriously explained this problem, the old-fashioned kick is to hit with straight legs, but now it has been improved, in order to improve speed and accuracy, it has been changed to have a diagonal back kick and stretch action, hit the opponent's face with the sole of the foot, and when the right leg attacks, the right foot kicks the ground and the power of the upper body twisting together, like tightening a spring, so the backspin force is very large, and it is very chic when it is done. Upstairs said to kick with your heels? I don't know how he kicks...

I'm used to stepping up and spinning, and I think that backspin still has a little inertia.
-
The power to really hit the target is concentrated in the soles of the feet, the top of the feet is straight, and a "one" is drawn in the air.

On the principle of back kicking, kick to the head position, the calves and ankles are relaxed, the upper body and the kick are forced in the opposite direction (that is, the waist is forced), and the legs will swing naturally when the calves are relaxed, that is, the thighs and calves are clamped, **in situ.
Power point. 1. When turning around, shake your head, turn your shoulders, raise your legs and knees, and turn your supporting feet, and synchronize at four points.
Power point. 2. Relax your calves and ankles.
Power point. 3. Kick the crotch at the moment.
Power point. Fourth, the center of gravity is slightly straight forward.

Step 1: Turn around and train.
Stand with your left foot in front of you, with the target in front of your body. Twist your body 360° to the right and back with your hips, and touch the target directly in front of you with both hands.
Step 2: Turn around and spin back.
On the basis of the first step, raise the right leg when turning, and attack the target with the heel or forefoot of the right leg with the force of the turn. Through a lot of target kicking training, master the movement and attack distance.
Step 3: Attack training.
The actual use of backspin is to meet the opponent when he uses a horizontal kick. During training, the opponent uses a left-footed horizontal kick to attack us. We use the backspin to meet the opponent's head while the opponent is kicking out. Through a lot of training, master the timing of the attack.
