LIFTING WEIGHTS!!! Yay or Nay???

[PunchDrunk]

how could you say that? could you give any proof? (I'm not trying to criticize, I'm genuinely interested)

Because power is mass x acceleration, mass being your bodyweight and acceleration being speed. If you don't move up in weight, yet gain power, the only other factor (assuming we're leaving technique out of this) is speed.

Also, strength and speed are correlated, meaning that the stronger you become, the higher potential for accelerating your movements you'll have. Remember that it is the muscle that enables movement, so less muscle activation will not make you faster.

Keep in mind, you can become a heck of a lot stronger without adding significant muscle mass. Neural adaptations. A proper strength regimen, integrated into the rest of a boxers routine is of great value.

acceleration and speed are two completely different things. You can gain power without changes in your muscle, by training the central nervous system.

Google for motor neuron for more info.

type I fiber is the strongest muscle fiber in the body and the the slowest too.

I totally quote this. The fact is: how to train this aspect?

I'm spending more and more afternoon at the local medicine library, trying to learn stuff, I'm looking forward to find a book that could teach me stuff, I'm genuinely interested.

No, acceleration and speed are basically the same thing.

That's what I'm saying. Sort of.

I don't need to google it, I have a stack of books about it right here.

type I fiber is the strongest muscle fiber in the body and the the slowest too.

Wrong, type I fiber is the most enduring, but the weakest. It is activated at the beginning of a muscle contraction, and type II fibers only activate after that, if/when the resistance is bigger than what type I can handle.

Word of advice, get the basics of all this down properly before you start giving out advice. The fact is, you've got a lot of this mixed up as of now, so you should look to learn more, before you consider teaching others.

Books I'd recommend:

Essentials of strength training and conditioning, by Baechle & Earle

Periodization training for sports, by Tudor Bompa

There are tons, but that is a good place to start.

Right right! BTW I'm not trying to give advice on such stuff, I'm trying to learn

I apologize for my past, present and future errors, and I strongly advice not to pay attention to what I say :P

I'll give a look to the first title, but I have had the second one borrowed to me for a pair of days from a friend of mine, so I can't exactly give an honest opinion about it because I didn't have enough time to read it all, but I remember that I thought that Tudor lacked a bit on the speed and agility part of periodization, as if it would have been a book for body builder.

But maybe I'm wrong, do you think that I should spend more time on it in the future?

What would ou say then are the best excercises for speed?

Not trying to be a prick, but the part of your quote that I highlighted seriously makes me doubt that you read said book....

There is no simple answer to that question. It differs from person to person, from sport to sport, it depends on where in your training you are, which equipment you have available, whether you have a trainer who can coach you in said exercises or not, etc. etc.

Training is not a simple matter.

[Don Flamenco]

alright, would you say that using plyometic excercises along with rubberband excercises a good option?

No, acceleration and speed are basically the same thing.

1. Acceleration is the change of speed in a time interval, which is just as different to speed as speed is to position.
a = dv/dt and v = dx/dt

2. You're probably thinking of the forumula F = m.a
Where F = force, m = mass of the system and a = acceleration of the system.
In that formula, the acceleration is a RESULT of force, the force is NOT a result of the acceleration. So it has NOTHING to do with punchingpower.
If there works a resulting force F on a system with mass m, the acceleration will be a. This also means that if a system is moving at a constant speed, there is no acceleration, which indicates that there works no force.

What you're thinking of is probably "beweginshoeveelheid" (in Dutch). Litteraly translated: moving quantity. A general term is I think impulse.
p = m.v
With p = impulse, m = mass of the sytem, v = speed of the system.
There is also an expression for the force times time.
I = F.dt
with d = differential
I is called "krachtstoot" in Dutch, which literally translated means: powerhit...

So basically it's true that the impact of your punch will partly depend on the mass you put behind it and the speed you move the mass with. But don't say it's like that because of Newton's law because, that couldn't be more wrong.
There are also MANY MANY more factors that come into play with the impact of a punch. Biomechanics, structure, angle, square inches...

With p = impulse, m = mass of the sytem, v = speed of the system.
There is also an expression for the impulse per time.
I = dp/dt
with d = differential, p = impulse, t = time.

Look at the formula as you yourself has written it. It clearly states that F is a result of m*a.

The factors you mention are mostly technical issues which is a different discussion altogether, and the ones that aren't technical, are factors you can't control or change - luck, coincidence, how you happen to be built.

Preparing yourself in the best way possible, in this case to develop more speed and therefore power, you can control, therefore this is an issue worth discussing.

Another point: A punch (and any athletic movement, really) is thrown as an accelleration, not at a constant speed.
