Sine Wave Motion is a movement unique to original tae kwon do to create maximum force in every moment according to the theory of power. in almost every moment this sine wave is utilized. sine Wave is natural and simple, and often I heard an policuctor say:
"Simple and natural = beautiful ".
Sine Wave Motion (also known as flow, or flow for short) is a special action of taekwondo. It is created based on the principle of force for each action to exert the maximum force. Almost every action in Taekwondo uses flow. The flow is natural and concise, and I often hear normal people say, "being concise and naturally beautiful !"

During class and in seminars Tae Kwon Do practitioners are being taught to use "Sine Wave" in their techniques.

In classrooms and technical seminars, taekwondo practitioners were warned to use "mobile" in their technology ".
What we actually do by random Ming this sine wave in tae kwon do techniques is moving the center of our body mass by means of a motion, which wowould look like a sinus wave if we wowould draw it.

When we use "flow" in Taekwondo techniques, we actually move our center of gravity in each action. If we draw the trajectory of this center of gravity movement, we will find it very close to the sine curve.

There are some key benefits to using sine wave that are linked to the training secrets of tae kwon do. moving our center of mass in the motion of a sine wave require us to keep our arms and legs bent while the body is in motion. to keep the arms and legs bent
During motion we need to be relaxed. relaxing the body adds speed to a technique because we are not all tensed up with one part of the body working against another. small increases in speed produce a large increase in the power of a technique.

There are several key advantages of using the sine curve flow, which is also the secret of Taekwondo practice. Moving our center of gravity in each action means that our arms and legs need to be slightly bent in each action. To keep our arm and legs slightly bent during exercise, we need to relax. Physical relaxation increases the speed of our technical actions because we do not have obstacles between physical parts due to physical tension. A small increase in speed leads to a large increase in technical operation power.

Secondly, when employing a sine wave we have to use the knee spring properly. that is to say bending the knee is what moves our body up and down as we move forward. using the knee spring while our body is in motion allows our center of mass to travel along
A curve, which by definition is another form of acceleration, which then helps us accelerate into a target.

Second, when we use a sine flow, we need to properly bend and stretch our knees. This means that when we move forward, the body is raised and lowered primarily by bending our knees. When the body is moving, knee flexion and extension lead to our center of gravity moving along the arc track, which theoretically implies another speed advantage, that is, it will make us closer to the target.

Finally, when using sine wave we are dropping our body downwards at the end of the technique with helps us use gravity to our advantage and keep our acceleration building until the point of impact.

Finally, when we use a sine curve to move our bodies down at the end of each action, this will allow us to take advantage of gravity to increase power before finally hitting the target.

To correctly apply the sine wave to Tae Kwon Do we need to modify the wave shape before we can achieve maximum power. in other words the sine wave is not a uniform curve as shown in the previous figure. the sine wave is modified so that the body drops as it
Passes the half way point of the technique, and rises to the maximum height at about the specified point and then drops rapidly at the end. the rapid drop at the end of the technique helps accelerate our mass into the target using gravity to our advantage.

To correctly apply the sine flow in Taekwondo, we need to adjust the flow track to achieve the most powerful effect. From another point of view, the sine flow is not as standardized as we have previously mentioned. After the sine flow is adjusted, the body starts to drop when the movement is half done. Specifically, the body's center of gravity reaches the maximum height when the movement distance reaches 3/4, then it drops at a very high speed at the end of the action. The body's rapid fall technology at the end of the action helps us put the weight of the body into the target, which correctly utilizes the advantage of gravity.

How much of a sine wave shoshould there be in a tae kwon do technique? The displacement that the center of mass moves from the zero line to get to the bottom and top of the sine wave this is called the ampltom. using too much sine wave defeats a technique because
All the body's energy and motion wocould be dedicated to moving along the sine wave rather than accelerating into the target -- (Harry Burke)

To what extent does Taekwondo use sine flow? A movement of the body's center of gravity from the lowest point to the highest point along the horizontal line is called an amplitude. Excessive use of this amplitude will cause technical movements to fail, because all physical energy and movements are used to flow up and down, rather than bringing power and gravity into the target. -- (Harry Burke)

Basics of Sine Wave
Base sine Flow
The basics of sine wave are down up down, in other words there is always a downward motion first, followed by an upward motion, and ending in a downward motion. there is however variations on sine wave, which are related to the motion, combination and speed
Of the techniques used.
The basic sine flows are bottom, top, and bottom. Another way is to always start the descent action, then the rising action, and finally the descent action. However, there is also a form of sine flow variation, which is related to the use of the action type, connection, speed, and other technologies.

In traditional Tae Kwon Do, the fundamental exercises and the tuls there are five different motions:

In traditional Taekwondo, the basic exercises and TRS include five different actions:
Normal Motion
Normal action
Continuous Motion
Continuous action
Fast Motion
Quick action
Connecting Motion
Connection action
Slow motion
Slow action

Normal motion (1-1-1)
In saju jirugi, saju makgi and Chon-ji Tul the tae kwon do student learns the normal speed of following movements. this is the first "motion": normal motion. movements are saved med in normal speed, with a complete sine wave in one breath.

Normal Action (1-1-1)
In the four-week dashboard, four-week block, and battle world, taekwondo students will learn continuous movements at ordinary speeds. These are the first "actions"-common actions. This action is performed at a normal speed and has a complete sine flow in one breath.

Continuous Motion (2-2-1)
In Dan-gun the tae kwon do student learns the second motion: continuous motion. Two movements are consecutively med, with two sine wave during one breath.

Continuous action (2-2-1)
In tanjunte, taekwondo students will encounter the second action-continuous action. Two actions are made consecutively and there are two sine flows in one breath.

Fast Motion (2-2-2)
Do-san teaches the student another motion: fast motion. Two movements are saved med consecutively in fast speed, with two sine wave and two breaths.

Quick action (2-2-2)
Students at Mount Thel will learn another kind of action-quick action. Two actions are made in a continuous and fast manner, which are two flows and two breaths.

Connecting motion (2-1-1)
In Yul-GOK there is another new motion: Connecting motion. Two movements are already med in one sine wave and one breath.

 

Connection action (2-1-1)
There is also a new action in chestnut-join action. Two actions are made in one flow and there is only one breath.

Slow motion (1-1-2)
Joong-gun completes the th and final motion: slow motion. in slow motion the movement is already med slowly, but according to the theory of power there has to be a slight acceleration at the end of the movement. there is one (slow) movement, one sine wave,
In one breath. Slow motion techniques are meant to learn the student body control and balance.

Slow action (1-1-2)
The fifth and last actions of the heavy root role are slow actions. The action is made slowly in a slow action, but the force is slowly made at the end of the action according to theory. This is a slow action, a flow, and a breath. The significance of slow motion is to train the practitioner to control and balance the body.

These five motions influence the sine wave, of which there are three variations:
These five actions affect the sine flow, so there are three forms of sine flow:
Full sine wave
Complete sine Flow
2/3 sine wave
2/3 sine Flow
1/3 sine wave
1/3 sine Flow
Only in normal motion, continuous motion and slow motion there is a full sine wave (down-up-down ).

Only normal, continuous, and slow actions have complete sine flows (bottom-up-bottom ).

In fast motion there is 2/3 sine wave, as there is only an upward and downward movement. an example is found in do-san Tul: The two punches following the apcha busugi. (movements 15 & 16 and 19 & 20)

In the fast action, the flow is 2/3 sine, that is, only the top and bottom movements. For example, in Mount Thel Island: two consecutive punching punches (15th, 16, and 19th and 20) after the first kick ).

In connecting motion there is 1/3 sine wave, as there is only a downward movement. an example is found in Yul-GOK Tul: The punch which follows the second hooking block (movements 16 & 17 and 19 & 20)

There is only 1/3 sine flow in the join action, that is, only the descent action. For example, in Chestnut, the punch action (16th, 17, 19th, and 20) after the hook in the hand is performed ).
