post everything you know about caffeine good or bad

[theALPHAone]

it stimulates the pancreas to make insulin, and its potentially bad for increasing th risk of type II diabetes

Increases Dopamine and Norepinephrine, dulls appetite, raises blood pressure, raises metabolism, gives you mental energy, increases nervousness and anxiety....

That is the most absolutely balls out wrong thing I've ever seen!

IN fact, within the last week they came out with a big study that said man who drank 6 cups of coffee a day had their chance of type 2 reduced by 1/2 and with women it was 30%

 

[theALPHAone]

no oofense bor

but who do you think funded the studies......?

the coffee industry

big vested interests usually do this when they know they have a product that may actually do bad things to you

a common tactic is to actually do studies that confront the flaw and to try to prove the complete oppisite

in the public mind its usually who shouts the loudest first, that wins or at least buy time

 

[Animal]

And your study on it increasing insulin secretion is where?

Caffeine DOES increase NA levels which clears glucose from the blood and you can't have NA and insulin around at the same time as they are antagonistic.

Yea, I love those coffee commercials hyping up their brand and trying to get you to drink their brand and more of it.
Starbucks and caribou are just begging people to come in.

You could look up the study and see who funded it and then we could have a problem with it.

But hey, if a study came out that said coffee had more caffeine than tea and it was done by the coffee industry, we couldn't believe it, right?

 

[theALPHAone]

on a side note Starbucks Breakfast beln has the MOST caffeine than all others

one 14 ounce cup has 550 mgs of caffeine where all other maybe have 250

also shots of espresson have only aboiut 60 mgs

fyi

nice to meet you

Supposedly you will burn more fat while you have caffiene in your system. Part of the reason it can increase endurance in distance runners/cyclists. Whether that is suffient for BB, I don't know. People learn faster with caffiene also.

 

[faller]

Oh yeah, it can increase muscle-fiber recruitment and people given caffeine felt that they were doing less work than they were without caffiene (there is a good study somewhere for that last comment).

It shifts your energy consumption away from burning carbs and toward burning fat.

Also it reduces the perception of effort but has no true physiological effect, just psychological.

at what dosage would it increase muscle-fiber recruitment, but not effect coordination?

 

[anthrax]

that's (IMO) the main benefit of caffeine : You don't feel so much the pain (or it delays it)

=> You train harder and longer
=> More cardio, more intensity, more fat burned

 

[faller]

>at what dosage would it increase muscle-fiber recruitment, but not effect coordination?

I guess it depends upon what the coordination is for, as well as your tollerance. If you have basically no tollerance, even 25 mgs should give some improvement, although it's usually 200mgs and up, and I mean WAY up!

You can get some nerve excitation, but I'd say an equal part of the population would likely get driven up the wall.

It switches your metabolism over to fat burning from glucose burning as it clears glucose out of the bloodstream

(Interesting that caffeine hasn't been looked as a way to suppress insulin!)

Anyhow, for many, that glucose clearing can be too severe and you actually get tired from the caffeine. It's hypersensitivity to caffeine though I don't remember the exact medical term for it.

>You can get some nerve excitation, but I'd say an equal part of the population would likely get driven up the wall.

Very true. I like caffiene before lifting or running, but when taken before mountain biking, I'm clumsy and nervous (boarderline scared). Just depends upon personal sensitivity I suppose.

also:

caffeine works by blocking the uptake of a natural sedative your body produces it actually is not a direct CNS stimilant like many think

it just blocks away the "sleepy" messenger in our body

however a theshhold comes where no matter how much you have you just crash soon after

 

[Lumberg]

also:

caffeine works by blocking the uptake of a natural sedative your body produces it actually is not a direct CNS stimilant like many think

if it blocks uptake of this sedative, then there's more of this sedative floating around....not sure if I'm getting this.

for examples SSRIs block the re-uptake of serotonin, thus increasing serotonin levels in the brain, which makes patients happier.

 

[Animal]

Ok, we're waiting on the increase in insulin and now it blocks a sedative?

I don't know, I always thought caffeine was a direct stimulant of the sympathetic nervous system? So now it's not 'direct' but works because of lack of a sedative which is being blocked?

Also, how is that sedative getting from the brain into systemic circulation as all too many know that if you drink too much caffeine you can get those muscle twitches which are initiated at the muscle and not at the brain.

 

[faller]

Caffiene prevents adenine (sp) from fitting into its receptor. Both are purines, but caffiene is methlyated. SO, it fits into the receptor, but doesn't do anything, while the adenine (the "sedative") can't fit into the receptor.

all my knowledge comes form books, so I can't just referance it for you bor
