Mudana Chikara is one of the watchword maxims used in Wado circles.
It’s one of a set of three, all described as ‘illnesses’, things to steer clear of if you want to remain on the right track. Mudana Chikara loosely means, ‘Do not use (too much) strength (to do the job)’, it is a key concept of Wado.
It is supposed to signpost the rule of economical movement, the embodiment of no waste, no fuss, no huffing and puffing and no tension.
It is so easy to describe what it is not but harder to pin down what it is – particularly if it is personal to your own technique.
Let me deal with the ‘tension’ thing first.
In between movements you are supposed to develop a feeling of live neutrality. I say ‘live’ because neutrality can easily slip into inertia, and an inert position is a dead position. An exaggerated example would be to say that you need to be in a position where you are deploying enough strength/energy to hold your posture, no more, no less. If your arm is stretched out (as in Tsuki) and someone rests their hand on the back of your hand, your hand should just gently drop under the extra weight; that’s enough.
Correct muscle management in movement is absolutely vital to efficiency. Often in our efforts to employ more power we actually end up sabotaging our objective with inefficient use of the muscles. Antagonistic muscles kick in and ruin the physical potential by actually working against what we want to achieve; I tend to describe it as like driving with your foot on the accelerator and the brake at the same time.
Wado instructors are very insistent on good muscle management; energy should be deployed appropriately and muscles should be fired off in the right order. Things can go wrong when the energy is generated from the wrong place and muscles work in isolated groups rather than a coordinated whole.
Energy should be turned on instantly, and then, just as abruptly, turned off; there should be no tensioned build-up and certainly energy should not be held on to. It is the ‘holding on to energy’ that causes an inability flow from movement to movement, or situation to situation, the energy becomes atrophied or stagnated. It is this ‘stagnation’ that can be fatal in a live situation.
But how do we know that we are using too much strength? Self-diagnosis is a really difficult thing; something might feel good but is it right? (Is it appropriate?). Clearly your Sensei can flag up if you are using too much strength, but only you can do the work on it.
My teaching experience tells me that this can often be a ‘guy thing’, women don’t tend to suffer as much from tension in their technique; guys tend to feel obliged to give their technique that extra thump; they have a model of strength in their heads and aspire to reach it, however unrealistic it may be. It is not something that can be reduced by degrees; the best approach is to soften it right back to zero and then build it up incrementally – but that takes a lot of time and some serious re-programming.
I suppose it comes down to energy investment. Some styles actually aim for over-kill, but really you have to calculate if all that investment is really necessary – can you afford it?
That is the thing about Wado, no frills, no artistic flourishes, all purely pragmatic and stripped to the bone.
