Point of most power

[P.A.L]

if you chamber and very slowly throw a punch there is a point that you will start to feel a tension and it will increase till you get to the end of range of motion, the point just before the tension in muscles start, is the point you looking for, think of all the limb and muscles as a system of springs, when you pull back you are at (-x) and velosity is zero as well as kinetic energy, the kinetic enrgey will be max at x=0 which is the relax point and after that it decreases again till it becomes zero at the end, i found the point around 2 inch before end of my punch. the only way of finiding the exact spot is the very high speed photography.

It looks pretty unanimous, judging by all the posts. I guess that is why the follow through is so important.

This also explains why shorter techniques, or jammed up techniques, aren't as effective.

Absoloutly, just before full extension is when you will achieve full power.

I read somewhere that some physics majors measured a punch as having it's greatest velocity (therefore, most power) at 70% extension. It is at this point that the hand begins to slow to prevent hyperextension.

Thinking about it (punch wise); there would be greater power before you twist your fist (excuse the pun), as the distance travelled would allow you to use your hip to gain more potential energy (comes to physics it does! )...

But then that would become a variable as the distance can vary on a fight... :-S Hmmm; interesting... *goes away and tries to work it out...*

On a kick, it would be just before you perform the actual kick, as you'll use most of the potential energy getting your foot up etc, and so once its up, you can use youir hips to do the kick...

Its all the hips which do all of the work, and so that is where you get all of your energy from... I believe (and it has been proven through Ken Jutsu) that if you aim behind the target (or carry on your punch) that most of your body weight will add to the potential energy being used.

In other words, the point of power is probably 5-10cm before the target...

Did anyone understand that?

Interesting. We were just talking about that last night. Sensei was pointing out that you lose power if you're too close to your target because you're unable to get full extension. On the other hand, you don't want to be too far away from the target because you expend most of your energy before you actually make contact. The most powerful strike is one that makes contact just before full extension and then drives through the target.

this is what i understood

1- you are not planning to become a Mechanical Engineer, but you have the potential to become a good medical doctor.

2- you are very much intrested in Potential Energy

3- you believe that hip does all the work and "Hips Don't Lie"

but the hip, you mentioned does have a effect, the velosity of punch has the hip speed inside it ( V(punch)=V(Hip)+V(punch/hip) you can ognore this formula since it is not really that easy to express it )

[Jeet Kune Do]

This is probably gonna sound like a stupid question....if so please forgive me, but I'll try to ask this without confusing ya'll with my stupidity.... .............at what point or "distance" would you say that a kick or punch has the most power?.......i know most people would say at the very end of the kick or punch, but is it possible that the "highest" point of power could be just before full extension of a kick or punch? I know that sounds stupid but I was curious to everyones thoughts.

!.) Okay, first off; yes - I am planning to become a Medical Doc, or either a Diagnostic Radiographer...

2.) Secondly, Physics and Maths go hand in hand, and P.E (potential energy is easy to understand)

3.) And as for Hips, well; they work! and its been proven!

but the hip, you mentioned does have a effect, the velosity of punch has the hip speed inside it ( V(punch)=V(Hip)+V(punch/hip) you can ognore this formula since it is not really that easy to express it )

Are you trying to say that V = velocity, and so;

Total Vel. = V(hip) + V(Punch/hip) and then whatever the result is, you can then use the acceleration formula to find out the speed, and then put that result in the speed forumla, and mess about with the constant variables of Time and Distance... And there you have it! point of most power, in different seceniors (sp?)

But seeing as the hip is a variable, you cannot work it out as easily as before... How can you work out the power of the hip, seeing as its a variable? Unless you could use the speed formula and measure the distance between a wall (so to say) and time it to see how long it would take to flick your hip at a certain distance (all with the help of a slow camera!)

It could be done! But i don't have the equipment! Have i lost you now?

to calculate the exact point at which the striking surface is moving fastest is practically impossible because there are so many variables. if you did come up with a figure, the error on it would be enormous. however you can find the point experimentally; breaking boards and stuff is a good way to do this.
