"Caffeine, as well all know, is a stimulant that is high in coffee, teas, guarana, yerba mate, and many energy drinks. For plants, caffeine is a natural insecticide. Caffeine as well as theobromine, paraxanthine and theophylline, are part of the methylxanthine family – psychoactive stimulants. Caffeine can be beneficial to some degree when you’re racing, but excess amounts can backfire and cause harm.
Symptoms of too much caffeine (too much ingested or impaired breakdown of it) include: nervousness, irritability, panic attacks, OCD, ADD, phobias, anxiety, muscle twitching, insomnia, headaches, heart palpitations, and digestive problems. But hey – there really isn’t a whole lot of caffeine in chocolate – even the pure unprocessed stuff. A typical 3.5oz bar of 70% cocoa is going to have roughly the same amount of caffeine as a cup (6-7oz) of coffee. If you’re eating 70% or higher chocolate, you’re probably not going to eat the whole bar. If you are, well you might have a problem. If you’re using <70% cocoa (not recommended) then there is even less caffeine in there so you’d have to eat more to get more caffeine. But you’d never do that, right? – Waayy too much sugar."
Caffeine is probably the most common drug used today, though perhaps you could argue sugar is a close second here, although not a true “drug.” But back to the definition of a drug – a food can have a drug-like effect in certain amounts, or in certain people. Many people use caffeine and sugar all day to keep them going and they use it to train and race with too and often perform well until their health suffers. (...)
By no means am I saying that moderate caffeine, alcohol, or even sugar use is a problem (for most). http://sock-doc.com/2012/10/athletes-on-drugs/
Your diet (such as sugar and caffeine) can impact the results of the test. For example, if you drink a lot of caffeine or ate a lot of sugar before one test and not the other, you most likely will get different results. http://sock-doc.com/2011/03/aerobic-or-anaerobic/
