LIFTING WEIGHTS!!! Yay or Nay???

[mmrooms]

im far from a beginner in training

you took that first post i had way out of context, when i said my speed hasnt changed i meant it hasnt changed noticeably.

But i know how to train speed, i dont know what made u think that

I don't want to sound rude man, but I think that you sure train hard, but at the best scientific way possible.

No, they are not completely different, without acceleration you get no speed.

ok, they are related, but not the same.

A punch is not thrown at a constant speed, it is an acceleration all the way through until it hits, for instance.

A punch IS thrown at costant speed (in modulo), but the acceleration change.

unfortunately it is in italian and it is on karate punch, but the biomechanic is the same.

I don't even understand what you're trying to say with your example, as it is complete nonsense.

It's the first example you find in any physics book to teach you the difference between speed, acceleration and mass. It was an example made by Newton back in the days to demostrate that mass and speed are unrelated.

Therefore a punch is thrown as an acceleration, not at a constant speed.

the link I just posted shown you in a scientific way that is right the opposite.

Blah blah... I suggest that if you want to discuss physics, you go to a physics board, and leave this one to people who are interested in training. Bye!

Man I think you are acting rude because you don't to admit that you were wrong. First you made nonsense statement on speed and acceleration, secondly you state that they don't matter.

How do you think biomechanics or kinesiology could exist without the fundaments of physics?

You have first to understand the behaviour of a simple object like a ball on an inclined plane, before understanding a punch.

A punch behaves like a Arbitrary-amplitude period pendulum, and I assure you this is the most complex kind of movement known by the human being.

mmrooms, you have to learn how to express yourself better, because it is impossible to discuss this when half your sentences don't make any sense.

A punch IS thrown at costant speed (in modulo), but the acceleration change.

WTF does that even mean? A punch is thrown at a constant speed?
It starts with the fist stationary, and ends up with the fist hitting the opponent at max speed (if thrown correctly) before it is halted and pulled back. That is obviously an acceleration until impact. If it was thrown at a constant speed, it would start at, say, 5mph and continue at 5mph all the way through.

Great job with the reference people in here can't read too!

I'm acting rude, because the two of you are twistring this into something completely different, and making a piss poor job of it, with your worthless references (since they're in Italian and I can't read what the hell it says), and incomplete, nonsense sentences that don't mean anything in English (which is my second language too, by the way).

Edit: Actually Hearnsz sorta does make sense, but I think he misunderstood what I meant for one. Secondly, he's overanalyzing things. Who cares if everything is in motion theoretically, when it is a useless assumption for the sake of understanding how to throw a punch, and how to train for it.

You don't understand it because you don't have a physic background. Btw, here some english reference:

http://www.google.it/url?sa=t&source=web&ct=res&cd=3&url=http%3A%2F%2Fesaform2008.insa-lyon.fr%2Fproceedings%2FMS22%2Fp_La_579.pdf&ei=5zHHSdepFdSFsAavtuXtCw&usg=AFQjCNFmb3Ob5iW2y1opxMWV-_xR_6Q4Mw&sig2=T6utHOvyYnbYsgOv3L0lrQ

Page 3: graphic of the speed. As you can see the variation in speed is smaller than experimental error.

But this is no news because in the 19th physician found out that when throwing a punch energy is accumulated in the ligament and tendons, that's why acceleration vary but speed remains constant in modulo.

I think this is one of the first thing they teach you in a kinesiology course.

Great job with the reference people in here can't read too!

can't you use an automatic translator? too lazy? Can't read the timetables?

I'll post you wikipedia:

http://en.wikipedia.org/wiki/Speed

http://en.wikipedia.org/wiki/Acceleration

Man, you really sound arrogant. You don't know the difference between speed and acceleration, still you try to teach us. I've a very poor opinion of you.

You are officially a TROLL. ****k off

You are officially a TROLL. ****k off

I think that now you understood that acceleration and speed are two different things, but you are too arrogant and proud to admit you were wrong.


Beware: the only place arrogance will lead to is the floor of the ring.

You're so full of ****, it's not even funny. Stop putting up links that have nothing to do with what you claim, and stop putting words in my mouth.

[mmrooms]

and stop putting words in my mouth.

man, you tried to say that speed and acceleration is the same thing and then you tell other people that they are full of ****?

incredible. Ridicolous.

what?


and how are you saying a punch is thrown at a constant speed, the initial velocity of a punch is 0 and the final is a higher number (A= deltaV/t)

[mmrooms]

and how are you saying a punch is thrown at a constant speed, the initial velocity of a punch is 0 and the final is a higher number (A= deltaV/t)

I posted two different paper from two different source that states the same thing.

Btw the final speed is again 0, unless you keep you hand movin. But I prefer to keep it in stance, or the speed are opposite, since once I move forward, then I move backward. didn't you thought about this?

It's written in the paper man, is basic physics, just go read it.
