We had the developers of Daedo out at our school to demo and test their latest hardware and software and got some interesting info from them. They are coming out with hogu sizes for kids 00 and 0 and new instep guards as well.
The info is specific to the Snappy kick vs. the Power kick and why the snappy registers when the power kick does not. I was told that it is indeed a design feature and is intended for just that. The developers are black belts and did not look at making the system based on competitions but rather correct technique. The system uses proximity sensors along with impact sensors. The proximity sensors measure velocity and then the impact sensors measure force. If you don't have what they consider a high enough velocity then no matter how much impact or pressure you have it won't register. They base this on their ITF technique and training when they were taught TKD. They also have Black Belts in Shotokan Karate. Their premise is on making sure you use correct technique and not just rely on power or muscle techniques. They gave the analogy of taking a towel and swinging it very hard and as fast as you can like swinging a stick through something and to hit someone. Then take that same towel and snap it on someone. The whip effect is what has more velocity and sting vs. the simple swing. You still need power but you also need the velocity as well. Don’t get me wrong, you can be very strong and hit with a ton of power and break someone’s bones. But was the technique correct? Now we have a different issue at hand. Which is, should any kick with simply enough force be a scoring kick. If what I was told is correct then the system is working as intended. Now do we ask for the intentions to be changed? Should a kick simply just be any old type of kick that hits with enough force or do we want correct kicks? besides if you can hit hard enough to break bones then you are most likely moving fast enough to score, regardless of technique.
They said that the round kick should have the same effect as the towel, with proper hip and pivot movement at the end of the kick. They also stated that the cut kick now needs to have that same type of velocity and snap to score, rather than simply pushing forward with an extended leg and jumping into the hogu and scoring a pushy type kick.
The guy was impressed with our students and stated that he had just come from another school (won't mention the name here) and that they had a hard time scoring using the system. He stated that they had really bad technique. We had one kid that was only 9 test the system and they guy said that his velocity and power were really good. We had some students that had some trouble with the system but when using the same equipment with students with better technique they had no issue with scoring.
It again goes back to what I was thinking and talking about in another thread, and that is that one may think they are hitting hard and with good technique but in reality that may not be the case. I see many competitors kick really hard but with an almost straight leg. They have some bend but not much and the kick hits with a lot of pressure but with no snap or what I call inside impact. I have stated a few times before that I have been hit by some pretty big guys and yes it hurts. But the hardest I have been hit is from a guy 135 pounds. His kicks do not move me but I feel them deep inside my body. Big guys kicks move me and hurt to some extent but his kicks just double me over. He kicks with snap on everything.
Just and FYI.
