Oi-Tsuki

Gyaku-Tsuki

I am 55 years old in April 14, 2015.  I am the karate instructor since 1976 in Rangoon (Yangon). I am the chief instructor and founder of soshiki karate since 1978.

Being a karate instructor for more than 39 years has been a rewarding experience.  Teaching is a lifetime activity and the following article of karate is the one of result of my own research for my karate books and articles.  My focus is primarily in the practical self-defense field rather than tournament training.   

In karate and its variants, tsuki 突き(Zuki) is used generally as a part of a compound word for any one of various punches, and virtually never stands alone to describe a discrete technique. Some examples of use for basic techniques include:

Gyaku-tsuki (逆突き) means stationary reverse punch.

Oi-tsuki (追い突き) means punch with the lead arm (when stepping forward - lunge).

The stationary reverse punch (Gyaku-tsuki) has always felt more stable (maintain good balance) and powerful for me (if you stable the stance and turn the hip, move very fast motion, putting the force of the body behind the punch) when sparring, but if you train both techniques enough I suppose you could get them equally powerful. We'll find any way to add the hips.

We do punch (Oi  tsuki) can add a forward thrusting of the hips/pelvis to supplement the forward momentum.

Oi tsuki is commonly known as the most powerful punch in Karate, because the step puts your body weight behind the punch.  The punch travels outward from the body in a straight line.  It finishes with the oi-zuki in line with your centre of the body.   Oi-Zuki / Oi-Tsuki in itself:

·        Punching arm in front and straight

·        Other arm pulled back and resting on hip

·        Both shoulders in line and facing forward

·        Hips facing forward and open

·        Legs in Zenkutsu-Dachi (70% on the front leg bent, short, 30% on the back leg  to be stretched straight out)

But the reverse punch (Gyaku tsuki) is more powerful and stable, because the rotational force of the hips into the reverse punching along with good balance and stability allows more powerful than straightforward thrusting and when punching a gyaku tsuki depend on a constructed stable base. In the most commonly taught versions, emphasis is placed on the tension of the practitioners' muscles, and movement of the body as a solid, stable unit.

Remember!

Hi SPEED combined with MASS is true that the faster the both punches the more powerful it will be. You must combine high speed (high momentum) along with your body mass when delivering your both punches. 

The most effective every punch delivers maximum mass at maximum velocity into a minimum contact area by less time.

Then please remember some of physics formulas might be wondering about Newton’s second law, F = ma (force equals mass times acceleration).  

More powerful punches is also come from skillfulness and based on experience.

Low stances are very powerful and assist delivery of power through the body to either the arms or the legs. High stances are more mobile and allow one to another position rapidly.

Equilibrium: There are three types of equilibrium: stable, metastable, and unstable. These three conditions are illustrated in a mechanical sense in the following Fig.
 

Equilibrium: (a) Stable. (b) Metastable. (c) Unstable.

Stable equilibrium exists when the object is in its lowest energy condition; metastable equilibrium exists when additional energy must be introduced before the object can reach true stability; unstable equilibrium exists when no additional energy is needed before reaching metastability or stability. Although true stable equilibrium conditions seldom exist, the study of equilibrium system is extremely valuable, because it constitutes a limiting condition from which actual conditions can be estimated.

Stable equilibrium exists when the object is in its lowest energy condition; metastable equilibrium exists when additional energy must be introduced before the object can reach true stability; unstable equilibrium exists when no additional energy is needed before reaching metastability or stability.

Stability and Center of Gravity

  

This refers to the bend in the knees and height relative to a normal standing position. Low stances are very powerful and assist delivery of power through the body to either the arms or the legs. High stances are more mobile and allow one to reposition rapidly.

Un-weighted stances are those where half of one's bodyweight is on each foot. Forward-weighted or backward-weighted stances place most of body weight on either the rear or the lead foot, respectively. Forward-weighted stances are more aggressive, allowing stronger punches and kicks because one's weight is already forward. Alternatively, backward-weighted stances are more defensive, allowing one to fall back more easily.

Most disciplines have one major stance that they regularly employ (generally from a standard guard position), and many variations of this standard stance which incorporate various combinations of open/closed, long/short, high/low or weighted/un-weighted. Typically, martial arts do not teach fighting stances until students have developed other basic skills.

The position of the centre of gravity of an object affects its stability. The lower the centre of gravity (G) is, the more stable the object. The higher it is the more likely the object is to topple over if it is pushed. Racing cars have really low centre of gravity so that they can corner rapidly without turning over.
