Caffeine Overdose

[chucky]

usse a supplement with out caffene in it ,much better for u

[skipperw]

thanks chucky.

think i'll be sticking to the energy drink with caffeine and maybe keep the caffeine gels to a minimum.

 

Suspect it may also be a case of build up. as a journalist, i live on coffee and cigarettes. i know it's bad...but i wouldn't be a good journalist if i didn't...now would I?

i did the redbull and vodka allot!!!! i did the filter coffees allot!!!! and i did the caffeine pills allot!!! i am still ok, but i must admit, dont think it can be the best for you!!! best thing for me was not to have any form of caffeine at all and then come race day you just have so 3 - 4 caffeine pills through the race... but try it out in training first or you might just blow bigtime before the finish!!!

Anita Valen non-negative for caffeine

Norwegian cyclist Anita Valen has tested 'non-negative' for caffeine, according to Syklingensverden.com. At this stage 'non-negative' means that she was over the prescribed limit for the stimulant, but her B sample has yet to be analysed. The PowerPlate-Bik rider was controlled at the Vuelta Castilla y Leon in March where it was found that she had a level of 14.5 micrograms/mL of caffeine in her urine. The UCI legal limit is 12.0 micrograms/mL.

The Norwegian cycling federation issued a statement saying that her B sample is currently being analysed, and the results will be known in mid-May. If that sample also contains a high level of caffeine, then she will officially be declared positive and will face a sanction from her federation.

This is 2003, I don't know if the limit is the same now.

 

CYCLING PERFORMANCE TIPS Caffeine

 

Caffeine is a legal stimulant which can be an endurance aid for activities of > 30 minutes duration. It is a member of a group of compounds called methylxanthines found naturally in coffee beans, tea leaves, chocolate, cocoa beans, guarana, and cola (kola) nuts and similar to the asthma medication theophylline.
During prolonged exercise, the onset of fatigue correlates closely with the depletion of muscle glycogen stores (and is delayed if glycogen is spared). The metabolism of free fatty acids (FFA) as an alternative energy source can lead to decreased use of muscle glycogen. Caffeine can increase blood FFAs, and it is felt that this is its major method of action. In one study, caffeine produced a 50% increase in FFA at 3 to 4 hours. This effect was seen after 300 mg of caffeine (an average 6 ounce cup of brewed coffee contains 100 - 150 mg of caffeine but a Starbuck's 8 oz cup contrains 250 mg!).

There is speculation that some of its benefits may also be related to its central nervous system effect as a stimulant, and a recent study has demonstrated a direct positive effect on the muscle fiber itself via a mobilization of calcium from the sarcoplasmic reticulum with a reported 7% increase in power output over a 6 second cycle exercise task.

In one controlled study, subjects were able to perform for 90 minutes to fatigue as compared to 75 minutes in controls (a 20% increase) after the drinking the equivalent of 3 cups of coffee or 6 caffeinated colas 1 hour before, even though values for heart rate and oxygen uptake were similar in both groups. Another study, looking at performance with acute altitude change (4300 meters), demonstrated a 50% increase in performance with caffeine supplements. How this would help at lesser elevations, riding in the Rocky Mountains for example, is not clear.

The suggested dose of caffeine for the recreational rider is 5 mg per kg of body weight (range 3 - 9 mg/kg) taken 1 hour before the ride although some riders take smaller doses periodically throughout the ride itself.

But there are potential side effects. Caffeine can cause headaches, insomnia, and nervous irritability. In addition it is a diuretic (can cause an increase in urinary water loss) and can lead to dehydration. However the biggest negative is that in high concentrations it is considered a drug and is banned by the US Olympic Committee and US Cycling Federation (to exceed the US cycling Federation's legal limit for caffeine - urine concentration of 12 micrograms/ml - one would have to ingest 600 mg of caffeine (6 cups of coffee) and have a urine test within 2 to 3 hours). Fortunately the ergogenic effects can be achieved well below these limits.

Habitual use will induce tolerance so a period of abstinence is recommended for several weeks before the event. The bottom line is that most endurance athletes consider caffeine useful if used correctly.

As far as I know there is not set limit for caffeine anymore.

WADA 2008 list:

 

The following substances included in the 2008 Monitoring Program:

(bupropion, caffeine, phenylephrine, phenylpropanolamine, pipradol, pseudoephedrine, synephrine)

are not considered as

Prohibited Substances.

I think the hub had one too many coffees. It keeps double posting.

I feel abnormal, I drink more or less 5 cups of coffee a year, even then I don't finish my cup. In winter I will drink maybe 3 cups of tea a week.
