8. About uniting the Expansions of the Body (伸び会い/Nobiai)


<Uniting the Expansions of the Body (伸び会い/Nobiai)>


This is particularly abstract and difficult to understand.

However, it is essential for achieving consistent accuracy and a sharp release.


The full draw (会/Kai) state appears static externally, with no extension of the arrow length or body, yet the phrase expansion (伸び合い/Nobi-ai) is used. This is a different expression from tension (張り合い/Hari-ai), so it's certainly something different from tension.


I interpret the expansion (伸び合い/Nobi-ai) as a way for a person to generate the explosive power needed to perform the next action instantly. Some explain it as being for generating arrow speed, but from a physical standpoint, it's unlikely to affect the initial velocity of the arrow, and I believe it's an illusion caused by hearing or sight.


To put expansion (伸び合い/Nobi-ai) simply, it's the state of preparation for the next action: after reaching the release starting position full draw (会/Kai), you determine the position of the follow-through (残身/Zanshin) and strive to smoothly and without wavering towards that position.

This cannot be achieved through tension. Excessive force will inevitably lead to wavering and timing errors. I believe everyone has experienced this at some point.


For example, consider a runner about to start a short-distance race. They are trying to move smoothly and straight towards their target goal from a stationary position. If they are not prepared for this, they will not be able to make a quick and precise start.


If we can recreate the same physical and mental state as at that time, we will be able to create a smooth transition from the static state of full draw (kai) to the next movement, resulting in a sharp release and a lingering resonance in the follow-through (残身/zanshin). (This is difficult to express physically.)


Expansion (伸び合い/Nobiai) can be thought of as being the same state as a runner who has taken their starting position and is about to begin running. They may appear still, but internally they are already moving towards the finish line.

Full draw (会/Kai) is the starting line.


To be honest, this level of mastery is something that those who simply draw and release the bow too quickly will never be able to experience.



Have you ever seen a karate kata competition?


It's a competition where participants compete with sharp, precise kata performances.


The release is similar to the kata performed in karate. We should emulate the pauses and fluid execution of techniques when moving from one kata to the next, and incorporate them into our own releases.

I believe we should strive to master a single kata: a release that is decisive, sharp, and precise, without any hesitation.


If you can achieve a comfortable follow-through (残身/Zanshin), there are certain benefits that can be gained from it.

The ideal form of hitting the target


Next time, we'll be discussing "Uniting the Expansions of the Body (伸び会い/Nobiai)" . We look forward to your next visit as you become more familiar with "hitting the target (的中/Tekichu)".

0. Starting Japanese archery again

Physical consideration of KYUDO -Japanese archery 0. Starting Kyudo (Japanese archery) again About five years ago, I re-started the Kyudo (Japanese archery) practice which I had been doing when I was a student. As I became a frozen shoulder, I decided to do something exercise and decided to start an experienced Kyudo (Japanese archery) practice. At the second year from the beginning (at Isejingu Kyudojo) As the goods I bought about 35 years ago were still usable, I started to practice at the public Kyudojo (Japanese archery hall). I am over 50 years old, but my body did not forget the form, so within a few months I was able to revive until I could use the 17.5 kg bow. At the time of re-start My sense was dull, but my physical form has not changed. That's my good point. This is the best Tekityu (hit) at restart. When I was a student, winning the game was everything, and I was working hard without thinking about anything. Well, my idea is engineeri...

7-1. About Tension (Hariai)~How to release a grip (Torikake) naturaly~

  Physical consideration of KYUDO -Japanese archery 7-1. About Tension (張り合い/Hariai)~How to release a grip (取り懸け/Torikake) naturaly~ <Tension (張り合い/Hariai)> To put it simply, "tension (張り合い/Hariai)" is the state of continuously applying force in the following three directions until release. If any other force is at work, the pushing hand or drawing hand will become unstable, and the arrow will not fly in line with the target. You would end up deliberately shifting the target you carefully aimed before releasing it. Tension (張り合い/Hariai)≈  The force of pushing straight along the arrow axis with the bow hand + The force of opening the draw hand straight along the arrow axis to the follow-through position + The force of releasing the grip and twisting the string, centered on the thumb It's helpful to understand the tension (張り合い/Hari-ai) of a full draw (会/Kai) as the state in which the entire body's strength, combined with the upper body's actions, creates th...

7-2. About Tension (Hariai)~How to release a grip (Torikake) naturaly~

Physical consideration of KYUDO -Japanese archery 7-2. About Tension (張り合い/Hariai)~How to release a grip (取り懸け/Torikake) naturaly~ <Tension (張り合い/Hariai)>Continued Now, the balance of forces at full draw (会/Kai) can be expressed by the following equation: Bow force = Force applied to the skeleton + Muscle strength supporting the skeleton + α (Force to extend both arms through the follow-through (残身/Zanshin)) When the draw (引き分け/Hikiwake) is over, this α is almost 0. During a full draw (会/Kai), this conversion of force is what we call tension (張り合い/Hariai). By making α as large as possible, you can produce a sharp, powerful and wide follow-through (大離れ/Oh-banare). So, what exactly should we do? As explained earlier, the force applied during the draw (引き分け/Hikiwake) is applied in the direction of folding the arm, while the force applied during the full draw (会/Kai) is converted into the direction of opening the arm. The force that guides the right hand straight through to the follo...
