Fundamental or superficial difference?

[Spartacus Maximus]

Considering the most basic punching and kicking techniques of Okinawan karate(mah also apply other karate), are body mechanics significantly different? 

Is the striking point(big toe, ball of foot etc) the only difference between techniques? 

[camotheman]

Hmm, that’s a good question. I don’t think that is the only difference. In my opinion, the technique you’re executing has a few different aspects. If I’m going to strike with seiken, my technique will be overall completely different than let’s say, ippon ken. My power, wrist structure, target, and overall technique will be different. Even using koshi can be different depending on the variation of technique I’m using. Sure, in essence, it’s still a punch, but it definitely makes a difference in how I execute the technique. The same principle can be applied if I was kicking with the toe vs. the ball of my foot. 

This is a broad question with a very specific answer in my part, but I feel like that can be applied to any technique in karate.

A lot of styles have adopted the same or similar mechanics over the past 100+ years, which likely come from Itosu Anko, as even some past masters who didn't train directly with him often learned his karate in school. That said, there ARE still styles with fundamental differences in mechanics. For example, KishimotoDi doesn't make use of hip rotation for power generation, but almost every modern karate style does. Motobu Udundi tends to "float" on the balls of the feet, but almost every modern karate style does not. Modern Shotokan and Kyokushin have made their motions so large that the mechanics can't help but be fundamentally different from the Okinawan styles they came from.

So how and where would the mechanics differ between a ball-of-foot front kick and one striking with the toes such as in tsumasaki or sokusen? How can it best be explained/decribed?

At first glance these kicks seem almost identical in movement except for the part of the foot used to strike with. There doesn’t seem to be a significant difference in the way the knee raised, extended and pulled back and set down.

I’m sorry, I misunderstood your question.

I would say that they’re pretty much the same in technique, speaking in terms of the knee motions, but they are different in execution. If I’m doing mae geri and striking with the ball of my foot, I’m driving my hip forward on the leg that I’m kicking with, to generate more force and power. If I was to do tsumasaki geri, I need to be much more aware of the structure of my technique, my hips will be more square than a regular front kick. If I lose that structure on a tsumasaki geri or use too much power, my toe / foot can bend to the left or right, essentially twisting my ankle to the side. 

Another thing is foot alignment, I’m flexing my toes up in mae geri to hit with the ball of my foot, whereas in tsumasaki geri I am tensing my toes to create that rigid structure.

As I'm most familiar with Uechi-Ryu I'll contrast that with many of the other karate styles.  One major difference in Uechi-Ryu isn't just that we kick with the toes, it is also how the kick is executed.  We don't do a snap kick per se.  We aim to chamber the kick with the foot parallel to the floor, and then the foot penetrates straight forward into the opponent, aiming for vital targets such as the bladder or floating ribs.  In fact, one of the pieces of feedback I often hear on black belt tests is "kick forward not up".  

The second major difference, which our kobudo students need to often unlearn, is the way we use hip drive.  In shotokan or many other styles, when you perform a punch or other strike, you'll see your belt flying all over the place while your hips add significant power to your strike.  In Uechi-Ryu, the hip drive is still there, but much more subtle.  The hips only move a few inches and the belt just wobbles a little bit.

With regards to kobudo I would be more inclined to suggest that most differences are superficial. When handling a weapon it will give you a lot of feed back on the best way to handle it. Whether that is swinging it about to figure out how to generate speed and power, or working with a partner and testing structure and leverage. Thus, stylistic differences usually are just that: a matter of style. If one looks at kata you tend to see the same sequences repeat, just in a different order. The best way to handle the weapon usually shines through when tested against reality.

In contrast, the human body is individual to each person, however similar the general shape and frame of the human body is to us all. It is also the most fundamental weapon everyone possesses. Thus, unarmed fighting styles have evolved in all cultures, and they are very much framed by the egoism of the teacher. Which is to say that whatever that teacher has learnt, has retained, and has determined works through experience, is what becomes their system. As a collection of levers and pullies built around a bendable structure, how we shape a technique also affects what it can do. As a result, how we choose to perform the technique dictates its tactical utility. 

Camtotheman and Aurik have already touched on the essential differences between a front kick with the toe forward and one with the ball of the foot forward. Each has a different tactical purpose. One is kicking into the body and the other through the body, and this is an important distinction. One is a tool for maintaining space and distance, and the other for doing damage on impact. Thus, even what looks like a superficial difference on the surface (The part of the foot being used to strike) it changes the techniques purpose entirely. And if a system is built logically, the nature of the techniques of the system will inform you of a system's general strategy and tactics very quickly. 

Even the hip thrust Wastelander mentioned can exist in many different ways. I will give two broad approaches. It can be used to try and catapult the limb which can lead to a quicker and more percussive strike. The double hip twist being a useful example of this approach's utility. However, it can be easier to see and if the timing is off the power diffuses before delivery. The other is to allow the weapon, in one example the fist, to lead and driving the hip in time with impact. The final structure, if tested is often stronger, and it can be harder to see coming. Michael Jai White's "Invisible Jab" is an example of this principle at work. However, because of the timing it can have reduced power and can lead to the target being pushed rather than hit with percussive force. 

Jodan Uke is another example where even a small difference changes the utility of the technique. If I bring the elbow up I may cover my head better, however, it is more poorly connected to my body. It opens the ribs up, and twists my trunk in a way that pulls my structure apart and weakens it.  If I keep the elbow down only one side of my head is well covered, but my body structure is aligned better aligned for me to have power in the technique. Thus, it has more utility as a potential forearm strike or clearing technique in a clinch, or even a block against something I have seen at the last minute and just want to get something in the way of. 

And so on and so forth. When we examine deeply how the mechanics affect the final technique, we begin to recognise in what situations a technique is useful. Then the techniques we have in tool box determine our tactics when confronted with violence. Thus, there is no such thing as a superficial difference. There are differences a person has not thought about and so the thinking is superficial, but the results never are.

I think it would depend on whether you are doing a snapping front kick, using mostly the knee, or a thrusting front kick, which tends to get more hip and possibly some lean back involved.

How many different ways are there between one way or another?!? Oh let me count the ways. The body can only move one way or another effectively before you start playing twister. 

Oftentimes, techniques from the various MA styles look the same. I mean, how many ways can one execute a front kick?!? The label changes but the darn front kick looks just like the other MA style.

Reminds me of this Bruce Lee quote, excuse me if I’ve mentioned this quote before…

”Because of styles, people are separated. They are not united together because styles became law!!”

This is the point of the first post. Focussing only on karate front kicks, there are perhaps only two kinds of mechanics. One for a snap and another type for thrust/stabbing kicks. All types of front kicks would be one orthe other as far as  body mechanics from the ankle upwards. 

In which category would we place the more commonly taught ball-of-foot mae geri and the sokusen or tsumasaki geri? Are they in the same one?

A ´snapping’ type kicks

B ´thrusting’ type kicks
