Soo............ I was curious.
As Instructors how many of you stick with the traditional exercises? How many do a blend of traditional and other stretches and warm-ups? And how many have abandoned the traditional junbi-undo for more "modern" stretches and exercises?
The knee permits flexion and extension about a virtual transverse axis, as well as a slight medial and lateral rotation about the axis of the lower leg in the flexed position. The knee joint is called "mobile" because the femur and menisci move over the tibia during rotation, while the femur rolls and glides over the menisci during extension-flexion.[20]
The center of the transverse axis of the extension/flexion movements is located where both collateral ligaments and both cruciate ligaments intersect. This center moves upward and backward during flexion, while the distance between the center and the articular surfaces of the femur changes dynamically with the decreasing curvature of the femoral condyles. The total range of motion is dependent on several parameters such as soft-tissue restraints, active insufficiency, and hamstring tightness.[18]
I must admit before I started the thread, I checked a certain individual's Asian Arts website, but was dissapointed to see the Junbi-Undo section was "under construction".Years ago I asked Dr. Bill to research the Uechi warm-up exercises and recommend a more "updated" set for those of us who would like a better way to begin our classes.
My personal interpretation of all this, if I was interpreting it correctly, is: When performing a front kick the knee automatically flexes past 90 degrees, (loading up for the kick). Therefore if you kick straight out without allowing the knee flexion, you are losing most of the power. (Although you may be able to reach the target quicker and without telegraphing). And secondly the "locking out" of the kick (aka contracting the quads), works to prevent hyperextension as I believe Bill stated earlier.SUMMARY
Peak powers were greater for the open stance than the closed
stance. The hip extensors and flexors were the prime movers
of both the hip and knee actions. The knee moments were
primarily used to reduce knee flexion and extension.
We do need to be careful here.KentuckyUechi wrote:My personal interpretation of all this, if I was interpreting it correctly, is: When performing a front kick the knee automatically flexes past 90 degrees, (loading up for the kick).

Although these may be warm-up exercises, it seems to me they also include stretches of sorts. If you are starting "cold" and jump right into the junbi-undo, they definitely cause you to move beyond the "normal" daily activity range of motion, and often in a ballistic manner.The junbi undo are warm-up exercises. One should not be doing stretching until one is properly warmed up.
Interesting. I'm not sure I've ever approached Uechi from the exact same angle, at least to that extent. I tend to approach Uechi from this angle when I'm working out solo, especially during the times in the past when I was not teaching a class. It's during those times I did primarily kata (Sanchin, as well as the other 7). So during such "workouts" I also try to concentrate on the kicks only as they relate to and compliment the kata. So I think we're on the same page.At first it was just centred solely upon sanchin ,and the need to loosen up never was really a factor that entered this training equation , although with time the underlying basis for kicks emerged into my conscious thought ,in a method that appeared miles distant from systematic kick training as we know it ,remember this approach is not based around the dan /kyu system ,were you have nearly instant access to the dynamics of kicks ,in the older system you are exposed to the nucleus of kicks and not the kicks ,this is a totally different approach to dynamics of movement and the philosophical mental training that comes with this totally different approach to what is known as uechi-ryu.
