Caffeine: Go big or go home:

[cepopeye]

Similarly, a recent (2007) study claims that women who drink six cups of caffeinated coffee a day have lower risks of high blood pressure than do women who drink three or fewer cups daily. The same study found that men and women who never drink coffee also have lower risks of high blood pressure.

haha, i just read this. So six cups of coffee a day is GOOD for blood pressure, NO cups is GOOD for blood pressure, and moderation is BAD for blood pressure.

this is fantastic news for me

[Aiden Bloodaxe]

WHAT THE...!?..Explain:tongue:

Edit: Wait,doesn't it depends on genetics,I think that's what I read.

It has something to do with the intense tolerance you gain from basically OD'ing regularly. It makes your long-term blood pressure drop because eventually your blood pressure normalizes even in the extreme caffeinated conditions, s when you go off its that much less than normal peoples

Cool,thanks man.

Do note that the study is referring to effect on women, men may react differently. Do also note that it is referring to six cups of coffee, not caffeine per se.

Another study that somewhat contradicts cepopeyes post and is definitely relevant to the training members of the forum:

Caffeine (CAF) exerts a pressor effect both at rest and during exercise, as blood pressure is higher than with placebo. The effect of acute CAF ingestion combined with intense resistance training on cardiovascular function is unknown, however. The primary aim of the study was to examine changes in cardiovascular function after completion of fatiguing bench-press and leg-press exercise after CAF or placebo ingestion. Twenty-two resistance-trained men ingested CAF (6 mg/kg) or placebo 1 h preexercise in a randomized, double-blind crossover design. They refrained from CAF intake and strenuous exercise 48 and 24 h pretrial, respectively. Heart rate and blood pressure were measured preexercise. After a standardized warm-up, 1-repetition-maximum (1-RM) on the barbell bench press and leg press was tested. When it had been determined, a load equivalent to 60% of 1-RM was placed on the bar, and the subject completed repetitions to failure. Measurements of heart rate and blood pressure were immediately completed, and mean arterial pressure and rate-pressure product were calculated. Results showed significant (P < 0.05) increases in heart rate (+ 10 beats/min), systolic blood pressure (+ 8-10 mmHg), and rate-pressure product with acute CAF ingestion versus placebo. No change (P > 0.05) in diastolic blood pressure across time or treatment was shown. To prevent elevated blood pressure and potential enhanced risk of heart disease, CAF intake should be monitored in at-risk men who participate in resistance training.

hahaha Rahf is right of course

[Aiden Bloodaxe]

I don't use caffeine anyway:smile:

[Miojo]

WTF?

[jan]

... wait, 6 mg per kg??? I only use 200mg, I'd die from 83x6 = around freaking 500mg of pure caffeine.

150-200mg per kg of bodyweight can result in fatalities amongst adults.

[Sakanem]

200 mg in total, not per kg :wink:

[jan]

Yeah, hahaha. I get inconsistent heartbeats from 400mg, haha.

[Rahf]

200 mg in total, not per kg :wink:

If 200mg total was the toxic count, hundreds of thousands of people would be dead. One cup of coffee contains roughly 100-150mg of caffeine.

The LD50 of caffeine in humans is dependent on weight and individual sensitivity and estimated to be about 150 to 200 milligrams per kilogram of body mass, roughly 80 to 100 cups of coffee for an average adult taken within a limited timeframe that is dependent on half-life. Though achieving lethal dose with caffeine would be exceptionally difficult with regular coffee, there have been reported deaths from overdosing on caffeine pills, with serious symptoms of overdose requiring hospitalization occurring from as little as 2 grams of caffeine.

No he's saying jan meant 200mg in total, not per kg.
I think.

[Sakanem]

yes.

[jan]

Yes.

[Rahf]

Language barriers and tired heads are fantastic sometimes.

[Oat]

Yes.










EDIT: HEY LOOK AT ME I'M AN EGG NOW!!!!! YOU'RE A GENIOUS JUJI!!!!

[jan]

Hahaha, from oat to egg:D

[Oat]

Hahaha, from oat to egg:D

Haha, I know. I was actually a nut just awhile ago.

[Kitosho]

i lof coffee

[Ashtar]

This is similarly fantastic news for me since I drink 8 cups or none each day.

But I am not a woman, sadly.

[jiayo-chris]

Hmmm i don't notice a huge effect from caffiene...

[Kaos]

What does it say about tea?!?!?!?!/1

[teef]

i hate caffiene. i love amphetamines. it also does wonders for trickings

[Am I Evil]

I doubt it's healthy to drink too many cups of coffee anyway. It's just a mellow stimulant. The studies have shown before that coffee is dangerous too, but yeah, better if it's good for you than bad. :3

i hate caffiene. i love amphetamines. it also does wonders for trickings
Is that meant as sarcasm?
Try ephedrine instead, it's a legal amphetamine derivate which you get on prescription from the doctor.
