The above is an article by Arnaud Cousergue, who appeard in a video of disaster not long ago. The idea put forward in the article is that the impractical stances and movements in the bujinkan enable you to one day fight well. This is an idea that we are seeing a lot of in TMA circles as people begin to question the use of stances and forms never seen in any type of alive situation.
"Training with low Kamae is difficult and allow us to create the necessary leg power that we might eventually need in a real fight."
Training partner compliant drills in a low stance will not develop leg power. Muscular power is a combination of speed and strength, that is, the individual that can reach his peak strength in a movement in the shortest time has the most power. This is trained by explosive lifting in the gym, as in jumping squats, explosive leg press or something of that nature.
"But by having trained so many years with these low Kamae, you are now able to move swiftly and give the proper distancing to the situation."
An unverified claim that seems to have more to do with faith than empirical evidence. Do boxers train in pad work with extra low stances so they they can perform in the ring?
"Remember that your Kamae is a shield and that Uke will never be able to harm you if you stay relaxed in the Kamae when he attacks. Do not move before the attack has been launched."
Again, if this were true it should be easy to find evidence for it, sadly there isn't any.
"As for any field of expertise, the basics are wrong. But by learning these wrong forms, you develop the ability to adapt them in a real situation."
OK, let's review. We deliberatly teach things that we admit are wrong but by the magic of Father Time, repetition of wrong suddenly becomes wright. It's like a baseball or cricket coach saying "Grab the bat and practice spinning around in a circle to hit the ball. Becuase you are getting so much extra spin in this exercise, when you really need to hit the ball there will be extra power."
"We deliberatly train people wrong. As a joke."
