Coffee Drinkers!

I've been scanning the JAP and found this, albeit 4 years old, but never the less:

Vol. 85, Issue 3, 883-889, September 1998

Metabolic and exercise endurance effects of coffee and caffeine ingestion
T. E. Graham, E. Hibbert, and P. Sathasivam
Human Biology and Nutritional Sciences, University of Guelph, Guelph, Ontario, Canada N1G 2W1

Caffeine (Caf) ingestion increases plasma epinephrine (Epi) and exercise endurance; these results are frequently transferred to coffee (Cof) consumption. We examined the impact of ingestion of the same dose of Caf in Cof or in water. Nine healthy, fit, young adults performed five trials after ingesting (double blind) either a capsule (Caf or placebo) with water or Cof (decaffeinated Cof, decaffeinated with Caf added, or regular Cof). In all three Caf trials, the Caf dose was 4.45 mg/kg body wt and the volume of liquid was 7.15 ml/kg. After 1 h of rest, the subject ran at 85% of maximal O2 consumption until voluntary exhaustion (~32 min in the placebo and decaffeinated Cof tests). In the three Caf trials, the plasma Caf and paraxanthine concentrations were very similar. After 1 h of rest, the plasma Epi was increased (P < 0.05) by Caf ingestion, but the increase was greater (P < 0.05) with Caf capsules than with Cof. During the exercise there were no differences in Epi among the three Caf trials, and the Epi values were all greater (P < 0.05) than in the other tests. Endurance was only increased (P < 0.05) in the Caf capsule trial; there were no differences among the other four tests. One cannot extrapolate the effects of Caf to Cof; there must be a component(s) of Cof that moderates the actions of Caf.

norepinephrine; epinephrine; diuresis; free fatty acids; glucose; glycerol; lactate; performance; methylxanthines; doping

It's basically suggesting that it's not just caffiene that seems to perk you up - it's something in the coffee that kinda interacts with the caffiene.

Anyone got any newer studies or opinions on this?

**Mudge** · 06-16-2002, 04:02 PM

My dad told me about runners who used to drink coffee to open up thier blood vessels a bit (as well as people who would run in the mountains to affect thier ability to carry oxygen in the blood via plasma increase).

I'm a recovering coffee addict, I am now down to 1-3 cups a day, 2 on the average. I used to drink anywhere from 8-12 cups a day, sometimes more. The only thing I really did was switch from coffee in the can, to instant, this way its not as tempting to finish off a whole pot.

Dr. Pain · 06-16-2002, 04:54 PM

My understanding is that the caffiene coumpounds in coffee are "xanthines", the coffee itself having almost 500 constituents??

Robboe · 06-16-2002, 06:44 PM

Dp, i don;t know exactly how much difference it actually makes but i think they're called "methylxanthines" and the other two are theophylline and theobromine. (they're basically CNS stimulants.)

And i'm not entirely sure about the constituents, but i have read somewhere that there's 1500 chemicals found in coffee, out of which we're familiar with about 20 - half of which are carcinogens lol.

Mudge: "My dad told me about runners who used to drink coffee to open up thier blood vessels a bit"

I was under the impression that caffiene actually constricted blood flow?

Haemodynamic effects of coffee and caffeine in normal volunteers: a placebo-controlled clinical study.

Casiglia E, Bongiovi S, Paleari CD, Petucco S, Boni M, Colangeli G, Penzo M, Pessina AC.

Medical Clinic, University of Padova, Italy.[/b]

The acute haemodynamic effects of Italian coffee and 200 mg purified caffeine were investigated in 15 healthy non-coffee-drinkers compared to individuals who consumed placebo (highly decaffeinated coffee for regular coffee, and china bitter extract for caffeine). Before coffee and caffeine consumption and 30, 60, 90 and 120 min afterwards, rest flow and blood pressure were measured, and peripheral resistance in the arm was calculated; an echocardiogram was also performed before and 60 and 120 min after caffeine consumption. Both coffee and caffeine significantly decreased rest flow, and increased peripheral resistance. Systolic blood pressure increased by 10% and diastolic pressure increased by 5% for at least 2 h. No variation in heart rate or cardiac contractility was found. No effects were observed after placebo treatment. It is concluded that Italian coffee and caffeine increase blood pressure via vasoconstriction.

Action profiles of smoking and caffeine: Stroop effect, EEG, and peripheral physiology.

Hasenfratz M, Battig K.

Comparative Physiology and Behavioral Biology Laboratory, Swiss Federal Institute of Technology, Zurich.

Twenty female regular cigarette smokers and coffee drinkers performed a numerical Stroop task in a 2 x 2 (caffeine x smoking) prepost crossover design. In the easier of the two different versions, caffeine and smoking reduced the reaction times (RT's) when given alone, but there was no additive effect. The Stroop effect itself (difference between RT's to numbers and RT's to symbols) was reduced by the two treatments only in the more difficult version, but the combination did not differ from the placebo condition. The physiological reactions to both treatments were additive, although the two reaction profiles were different. Smoking increased heart rate, blood pressure, finger vasoconstriction, respiratory frequency, EEG dominant alpha-frequency, and beta power and reduced respiratory amplitude, EEG delta and theta power. Caffeine increased blood pressure, finger vasoconstriction, motor activity, frontal EMG, and EEG theta power and decreased heart rate and EEG beta power.

The effects of caffeine on physiological functions and mental performance.

Battig K, Buzzi R, Martin JR, Feierabend JM.

Polygraphic monitoring of several physiological variables was done throughout an experiment investigating the effects of caffeine on mental performance. The experiment started with a mental maze learning task. Then the subjects were given the test beverages according to the group design (CC group (N = 16): 300 mg caffeine in decaffeinated coffee, DC group (N = 16): decaffeinated coffee, WW group (N = 8): warm water, and NB group (N = 8): no beverage). The experiment continued with a letter cancellation task which was followed by a second mental maze learning task. The caffeine treated subjects differed from the other groups by increased regularity of letter cancellation performance, as indicated by decreases in intraindividual variance. They also differed from the other groups by a slight but significant acrodermal vasoconstriction. No intergroup differences were obtained for mental maze learning, heart rate, respiration, muscle tension, and skin conductance. The results suggest therefore that the drug at this dose level improves behavioral routine and speed rather than cognitive functions and that the vegetative side effects are minimal.

never tasted coffee..can anyone explain what it tastes like ? and don't say chicken !

ponyboy · 06-17-2002, 05:52 PM

Funny, all that research TCD, I was always told that coffee was good after a long night of drinking because it caused vasodilation and got rid of your headache through increased blood flow.

I guess those frat boy remedies don't hold a lot of water (and neither do I after a long night of drinking).

No, coffee helps sober you up because it is a CNS stimulant and has the opposite effect of alcohol, which suppresses CNS activity.

I can't see it getting rid of your headache either, cause they both have diuretic effects and dehydration isn't gonna do too much for a hangover.

The reason i posted it was cause it got me thinking whether people using ECA would possibly benefit more from actually "drinking" their caffiene as opposed to taking it in pill-form.

Thanks TCD.

My boss showed me an article in a recent Mens' Health magazine, that coffee can inhibit muscular growth due to the caffeine blocks the body from utilizing calcium. IS there any research on that???

Coffee is my friend.

Something like that, I have always heard that it strips calcium from the body, as well as minerals and vitamins. Its definately evil for older women, calcium supplements would probably be adviseable for people with bone density problems. I've been a milk drinker my whole life, I've never had a problem with breaking anything.

I wouldn't believe that large amounts of coffee are good for you though, which is why I dropped my intake down severely, besides the high blood pressure aspect.

I actually tested in the hypertension area until I dropped my caffeine intake by a large amount.

Not sure about actual growth, but i know that caffiene can mess around with the calcium release at the synaptic cleft so can effect contractions.

so drinking coffee after running for 30 minutes on an empty stomach is ok... ????

sawheet · 02-04-2003, 09:54 PM

Coffe has Theopholyne in it. I think Theopholyne is a beta inhibiter that aids in dialation of the bronchial airways, too lazy to reasearch that. I love my Starbucks every day!!

oceangurl01 · 02-04-2003, 09:58 PM

whats that supposed to mean? i dont understand

Dero · 02-04-2003, 09:59 PM

This I found,but it's from 95...

Could be too old???
