I'm not sure that any of them do.\n\nIf you follow the research that comes out on caffeine, you'll notice that every time there is a paper published that says caffeine improves your performance in some way, there is another one that says that caffeine hurts your performance.\n\nThey may drink coffee, tea, Pepsi, Jolt, eat chocolate, pop caffeine, but does it improve their performance? \nThe jury is still out on that one.

if u have this workload on you, you can try this: a herbal tee from south america called mate or yerba mate. it has just little caffeine but plenty of other nutrients that really complement the stimulation effect of caffeine. it will give u more stamina than coffee and, unlike coffee, it is absolutely harmless, it is healthy in fact, u can drink it all day, just do not drink it right before going to sleep \n\ni used to drink lots of it instead of coffee, when i realized that i simply cannot continue drinking so much coffee.\n\n  or try Korean ginseng - eleuterococus (i used it when i was writing my thesis and had little sleep and much work) or leuzea=rhaponticum= maral root (i take this one or eleuterococus to combat severe jet lag when the necessity arises - they wake me up, so i am active when i am supposed to be, so i get myself tired and then in the evening i can fall asleep more easily than if i spent the whole day trying to keep my eyes open! . so i think it is equally good for shiftworkers or the situation u described)\n\nBUT: dont take it before u go to sleep, it is imperative thet u sleep well since u dont have much time for that...

First, do not listen to any answers if people do not qualify their info.  Red Bull was actually created as a sports drink in Europe, when brought to the US marketing determined they had a wider audience (higher sales) if they marketed as an energy drink.  It is like gatorade with caffeine.  IT contains stimulants, and yes, stimulants speed your metabolism, but very minimally and are not going to help you lose weight, the extra energy however, gives you the capacity to workout harder, which in turn burns more calories.  1)Drink = 2)more energy = 3)better workout = 4)weight loss.  without 2 and 3, 1 DOES NOT equal 4.  On the downside, most stimulants also act as diuretics (they dehydrate you).  Dehydration weakens performance (worse workout), particularly in longer duration cardio.  \n\nGOOD SIDE BAD SIDE, make the smart choice, if you feel better when you workout while or after drinking one, go for it, if you don't, then don't.  \n\nRemember, it is ultimately the workout (and diet) that determines your weight loss, supplements (pills or drinks) do nothing on their own, they work through their impact on your workout.

I'd be real hesitant to rely on caffeine during practice. It will give you a boost, but two-a-days are so long, you'll end up crashing part way through. They're absolutely miserable, but you've just gotta grit your teeth and grind through it. Stick with water and gatorade if you're allowed to have it, and make sure you get plenty of sleep. During your break, make sure you eat some fruit, especially bananas.

OF COURSE!!  I love the St. Louis Cardinals and Albert Pujols is the best player who hasn't been suspected of steroid use!!  HE's even one the best players compared to those who did use steroids!!

Caffeine increases heartbeat, respiration, basal metabolic rate, gastroenteric reflexes, and the production of stomach acid and urine; and it relaxes smooth muscles, notably the bronchial muscle. All of these changes vary considerably among people and may depend upon the individual's sensitivity to this drug, his/her metabolism, or upon whether the consumer habitually uses or rarely uses caffeine. How long caffeine's effects last is influenced by the person's hormonal status, whether he/she smokes or takes medications, or has a disease that impairs liver functioning.\n\nSubjectively, people report that caffeine gives them a "lift." They feel less drowsy, less fatigued, more capable of rapid and sustained intellectual effort. They also report improved performance of some manual tasks such as driving. However, caffeine may restore only those abilities or feelings the person had before fatigue or boredom set in. Studies have also shown that caffeine decreases reaction time to both visual and auditory stimuli; it does not significantly alter numerical reasoning (arithmetic skills) or short-term memory; and it can diminish performance of manual tasks that involve delicate muscular coordination and accurate timing.\n\nWhen caffeine is taken in high doses it can cause many unwanted side effects.\n\nStudies of the effect of caffeine on sleep have shown that one strong cup of coffee, drunk 30-60 minutes before going to sleep, can cause restlessness and difficulty falling asleep, increased body movements, a tendency to be awakened more readily by sudden noises, and a decreased quality of sleep.\n\nThe wide variation in caffeine's effects on sleep may be related to whether the person is a habitual, heavy user or a non-user of caffeine. Non-users report greater difficulty with sleep after consuming caffeine. Heavy users may also experience sleep disturbances; however, their increased tolerance to the effects of caffeine affects their perceptions of disturbed sleep. Often they sleep for shorter periods of time, but have grown accustomed to this pattern.\n\nIf you use caffeine and are having trouble sleeping, you may want to try cutting back on your total daily intake or avoid consumption 5-7 hours before you plan on sleeping, to allow time for the caffeine to be metabolized.

Two cups of coffee is about half the recommended maximum daily caffiene intake for males. (100mg)\n\nCoffee had been proven to improve mental alertness and general cognative ability. As long as you're not drinking energy drinks as well as coffee, you shouldn't be experiencing anything other than minor side effects.

He didn't take drugs, he just trained harder than anyone else.\n\nAn independent physiologist familiar with the study commented: “This study shows that long term training has a lot bigger effects than we thought. They followed Armstrong – a well-known hard trainer – and the changes in his efficiency over seven years are really quite amazing. We wouldn’t be surprised if some major physiological changes happened, but here’s a real quantified example.”\nHe added: “Generally there are two ways to improve efficiency: Train your maximum capacity to be very high, or train your sub-maximal capacity to be very efficient. In Armstrong’s case, he did both. In the lab they measured his performance against standard oxygen consumption and by the end of the study he was much more efficient utilizing the same amount of oxygen. But on the road,” he pointed out, “it means he can go faster and get more guys off his wheel.”\nEffect of cancer, therapy nil\nThe period that started when Armstrong was 21 and just turning professional and ending at age 28 with his first TdF victory, also included his cancer diagnosis, surgery, chemotherapy and recovery. About eight months after chemotherapy ceased (August 1997), Armstrong was tested in Coyle’s laboratory in the same manner as in his other four visits. The results showed that he “displayed no ill-effects from his previous surgeries and chemotherapy” and were in line with measurements expected from highly trained athletes during periods of detraining, Coyle added later.
