- The first time I was exposed to real top-class fighters in
- Karate, I noticed that they did something that I did not do: They
- stamped their feet with each technique. Furthermore, they stamped
- their feet in precise timing with their blows.
-
- Years later, when I began to study Kendo, I found that
- everybody stamped their feet. The sound of their right foot hitting
- the floor was also simultaneous with the sound of their shinai hitting
- the target. The result was a loud, resounding BAM! when they struck.
- The stamping action somehow added to the force of the blow.
-
- Over time, I have polished my own fumikomi, and I think I
- finally have gained some understanding of the effect. This has led me
- to an uncomfortable discovery: either my understanding of fumikomi is
- flawed, or most people time the stamping action improperly.
-
- In my understanding, the stamping action is not done for its
- own end; it is simply a consequence of catching yourself from falling.
- As you launch yourself forward and shift your center of gravity, you
- immediately begin to fall at 9.8 meters per second squared. Because
- your front foot is off the ground reaching forward, you simply free
- fall until your right foot lands with a stamping action, breaking your
- fall.
-
- In order to use the acceleration due to gravity to help power
- your blow, you must strike before you break your fall and dissipate
- the energy of falling. More specifically, you must break your fall by
- hitting your opponent with your weapon, not by stamping your foot. At
- the instant of contact, all your weight is coming down on your
- opponent (via your weapon), instead of coming down on your front foot.
-
- So here is the dilemma: to use gravity properly, shouldn't you
- make contact BEFORE your foot hits the ground, and breaks your fall?
- As I have fine-tuned my timing, I have indeed found that, instead of
- hearing one single BAM! of my foot and my sword, I hear kaBAM!, where
- the "ka" is the sound of my sword hitting the target, and the BAM is
- the sound of my foot. I truly feel my strongest when I achieve this
- timing.
-
- So here is the question: Am I deluded in thinking that I
- understand fumikomi? Or are others mistaken in timing their
- foot-stamp and sword strike simultaneously?
