Caffeine bombshell

[ravens]

WADA should ban slim Red Heads too - as that what get's my heart racing.

red heads huh ..... (freak)

 

[ravens]

Just ignore it.

ignoring and banning are all the rage

There are far too many benefits on learning capacity to worry about what it does to your heart. 1-2 doses a day is good for your brain.

 

[Willy_Voet]

The authors themselves acknowledge the limits of their study. They further state that they were 'grossly underpowered'.

Furthermore, there is one aspect of the study they do not mention, but I think I have figured out from the experimental design...

What were these people doing for the 1 hour after drinking an espresso? They were sitting around have blood drawn, being hooked up to machines and generally not working/running around.

I would imagine that sitting still for an hour has something to do with decreased blood flow, but what do I know, I'm just a...well, not a physiologist. Still, decaf drinkers did not see the 22% decrease in brachial artery flow-mediated dilation, but I think this difference would be lost in the noise if both sets of participants were hooked up to turbotrainers pushing 70-90% of their lactate threshold.

Furthermore, participants were excluded if they drank more than 2 cups of coffee a day and they were not allowed to have caffeine during the course of this study. In short, they set the system up to find an effect and !surprise!, they did. They list 3 other studies in their paper which had results that contradict theirs. Those 3 other studies used less homogeneous populations.

Caffeine does all sorts of great things for an athlete (some noted in this study, too). It decreases insulin excretion, which decreases sugar storage making more available in the blood. It is also a neurostimulant.

 

[Ripper]

The study is by proper qualified professionals, and 20 people is more than many other medical trials I have seen, so I wouldn't ignore it. It's information that must be noted, but of course with caution.

It's careful to say that in the long term caffeine is still good for the heart because of the other properties. But I'm just interested in the short term effects on performance. It has been thought that caffeine is a sports aid. Maybe the extra concentration overrides the possible cardio issues, I don't know.

An N of 20 for this type of study is crazy small. Noth really worth worrying about.

 

[brianf7]

Caffine opens up the arteries to the lungs and the conery arteries so you blood pumps faster.

It also causes dehydration so drink more and dont stop behind the old gum tree for a pee or you know what or you may get a fine for indecent exposure.

Drink and be merry if it helps why not.

from personal experience caffeine is a great race aid as are most stimulants. i notice no change in heart rate with myself on or off caffeine. i have seen negative study outcomes and many positive outcomes regarding caffeine and health/performance. a recent one found that the fluid loss(dehydration) is much less than once thought also teas and coffees have many widely recognized health benefits. considering that 100s of millions if not a billion people worldwide of all walks of life and health levels consume it daily and are not dropping dead i would say its pretty safe lol. bottom line narrow study which looks at 1 factor and uses 20 people or so pseudo science as with most "studies" i read.

The study was nothing to do with people dropping dead. It simply said it could be bad for your cardio in the short term, which is where the cycling interest comes in.

The best stimulant I think is modafinil. Lasts longer and gives smoother feel. Definitely improves time to exhaustion, which is why it's on the banned list.

It does not surprise me that Chunky here would be familiar with modafinil. From the Wikipedia page:

"Some of the positive effects of modafinil may be limited to "lower-performing" individuals or to the individuals with lower IQ."

You cannot make this stuff up.

I guess this begins to explain why our oft-banned resident troll loves to come on here and toe the pro-PED line.

It's refering to IQ levels, not sport, silly.

Plenty of pro athletes took modafinil in the early part of the 2000s before it was banned. Studies have shown it does improve athletic performance.

You know what else is on the banned list?
You.

I was starting to wonder about your comments. You sounded like BPC.

Ladies and Gentlemen....

I give you the post of the day....

You know what else is on the banned list?

Brilliant post!

But thanks to BPC this thread does serve a purpose......

 

[Dr. Maserati]

red heads huh ..... (freak)

Yes - Redheads should be banned by WADA and the UCI...... does this not get your heart racing more than one espresso?

Hurry Pat - the check cleared days ago!!

Because if Dave Brailsford "looks me in the eye" I think I will fail his test.

I tried to come up with responses that would not get me banned for being lewd. I could not.

You see - more dangerous than a little espresso!

And whats worse is I decided to see if RedHeads were banned by WADA previously........ so I put in "Dick Pound Red Heads" in to my browser - I nearly had a heartattack

Here's a present for you Doc.

 

[BikeCentric]

But wait a minute Doc, wouldn't Redheads (such as the examples provided thus far in this very serious discussion in a serious thread) be natural performance enhancers and thus not subject to banning?

Because he was.

Sadly, until we can find a way to tactfully block his network, it's likely he'll just get yet another e-mail address and start-up again.

(Not calling you mindless)

I have suffered the mindless blacklisting in my own business's web presence, and its effects are much more troublesome than a little forum bannage. The shared server was sending out spam. So the whole server was blocked. This is like saying some operation in the basement floor of an office building is bilking old blue haired ladies of their savings .... so the whole building was bombed.

The present system is adequate if people resist the urge to respond. He's gone, he'll be back. Just ban him sooner. It's business as usual at Kramerica.

her hair is what catches your attention? go see your doc

The frailty of your self control is appreciated by many. Redheads do scare me and for many crazy reasons.
My wife is not a red head. She scares me too but that's a separate issue.

You didn't hear this from me, but she scares you because she is a female. The ones with the red hair just take it another level.

I will go this far out on a limb - and we'll see if one of the lady mods will feel compelled to come by and slap me around a bit, not that there's anything right with that - and say that playing connect the dots with freckles to make your favorite stage profile can be a real bonding experience.

The natural Read Heads are the most dangerous.

Ever notice how Red Heads are never mentioned in Cycling publications - or by the riders?.............. Omerta.

C'mon JV - leave the kid in Wendy's, he sounds like he wont be able to go anywhere for a while - this is an issue that requires immediate action.
