Jay Posted March 19, 2008 Share Posted March 19, 2008 I am lacking in the body weight department my punching is a lot better than most of the people I know but thats only because I know how to punch properly HAHA my current bodyweight is about 130lbs so I think I would struggle to hit much more over 700PSI The key to everything is continuity achieved by discipline.

DWx Posted March 19, 2008 Share Posted March 19, 2008 Which leaves me to add, that anything that reads power, sometimes doesn't always read the mass behind a technique. Just the speed.This is a good point to make. Those type of targets only measure the impact power, the peak power. If anyone is into board breaking than you will know that hitting a stack of boards with spacers requires you to sustain a certain level of power over distance in order to go through the boards; whereas not using spacers requires a more power at the moment of impact which you don't have to sustain it over distance (as much). Those type of pads are really only effective for the first type. "Everything has its beauty, but not everyone sees it." ~ Confucius Link to comment Share on other sites More sharing options...
bushido_man96 Posted March 20, 2008 Share Posted March 20, 2008 Which leaves me to add, that anything that reads power, sometimes doesn't always read the mass behind a technique. Just the speed.I am not so sure. Power=mass x velocity squared, I do believe. If this is the case, then I don't think that you can really cheat the machine. If the machine is reading power, then it is detecting the mass in some way, and using it to relate the power. https://www.haysgym.comhttp://www.sunyis.com/https://www.aikidoofnorthwestkansas.com Link to comment Share on other sites More sharing options...
TraditionalDan Posted March 20, 2008 Share Posted March 20, 2008 I agree with bushido man and DWx. There is a medium however.I agree that speed = power, but if I was to perform a reverse straight punch on the machine I wouldn't get the same results as I did with a hooking punch (which got me 9300). But I personally think that a reverse straight punch (contact with the seiken) to an opponent's body (not the head) I would cause alot more damage than the punch I performed on the 'Dragon Punch' (hooking punch). Simply because of the extra mass behind the technique, but then, that it only because of the opposing mass (the opponent's torso).I conclude that, it may read your power for that particular technique, but the makeup of the recieving reader is not that of the human body. As such it will not be able to determine the outcome of the technique if it was inflicted upon a human. Brighton Shotokan Link to comment Share on other sites More sharing options...

As such it will not be able to determine the outcome of the technique if it was inflicted upon a human Well first things first to get straight is the definition of powerPower=Force x VelocityAs we all know F=MA=Mass x AccelerationSo Power=Mass x Acceleration x VelocitySo what this basically means is that the more mass that you put into a punch that harder you will hit. Also the more acceleration that your arm has the more powerful your punch will be. The greater the final velocity also the more power your punch will have.For instance take a standard swing for example by someone that is untrained. If he just moves his arm at a constant velocity he is going to have less power than if he is accelerating as that is part of the equation so if he accelerates to that same velocity throughout the travel of the punch it will have more power than one that accelerated reached a velocity and continued to travel.In regards to damage caused, why a straight punch to the body may cause more damage than a hook punch is to do with the pressure exerted by the punch. Straight punches are generally exerted to a smaller area than the hook punch due to them being able to be targeted better by the average practitioner.Pressure=Force/Area So the bigger the force in a smaller area the more damage is generally done. If a locomotive moving at slow speed with minimal acceleration or a bullet at high speed hit you with a large acceleration which do you think is more likely to kill you even if they are exerting the same amount of force.The bullet of course.End Physics Lesson *bows* The key to everything is continuity achieved by discipline.

TraditionalDan Posted March 20, 2008 Share Posted March 20, 2008 Thanks for the equation (which I am aware of), I am just bringing up something for us to think about.I still don't think I would have got the same score on this 'Dragon Punch' machine with a straight punch, even though the mass is much greater behind it. With a rounder arm technique however, the hand-speed is much greater, but the mass behind it is less. But I will get a better score.The reason being I think, is that the punch ball on the machine is actually quite small (speedball sized). So it doesn't really have the time to caculate the mass thrown at it, and being as it is quite small it doesn't give much feedback. So the mass is therefore not needed for a higher rating. If you catch my drift..? Brighton Shotokan Link to comment Share on other sites More sharing options...

You may be able to generate more speed on the hook punch. When you look at the equation, adding speed can result in better results as opposed to adding more mass, because of the squared portion of velocity. Therefore, if you can add more speed, it tends to have more effect than adding just mass. Both have their props. https://www.haysgym.comhttp://www.sunyis.com/https://www.aikidoofnorthwestkansas.com Link to comment Share on other sites More sharing options...
