Caffeine use for athletes is a worldwide known and tested idea. Many athletes use caffeine as a legal performance enhancer, as the benefits it provides, both physically and cognitively outweigh the disadvantages.
The benefits caffeine provides influences the performance of both endurance athletes and anaerobic athletes. Caffeine has been proven to be effective in enhancing performance. Below is more detail on who benefits more, trained athletes in comparison to untrained, males in comparison to females and aerobic vs anaerobic athletes.
Caffeine  is classified as a stimulant drug. Once consumed, it is absorbed in the stomach and small intestine as well as being circulated throughout the body. Caffeine is most commonly known for being in coffee. It is also found in tea, chocolate, soft drinks, energy drinks and medications. Coffee is made from coffee beans, which are an exotic bean, roasted fruit from the Coffea arabica bush.
The short term effects from caffeine are usually noticed after 5—30 minutes and long term ones last for up to 12 hours. Those who use caffeine regularly, most often drinking at least one coffee a day, can become dependent and addicted.
Caffeine acts on both the respiratory system and cardiovascular system. The cardiovascular system is the pathway the human body uses for circulating blood, supplying oxygen and removing waste products. Physical benefits include bronchodilation. Caffeine also increases adrenaline levels in the blood system. Adrenaline, is commonly known as the 'flight-or-fight' hormone, so prepares the body for physical activity. Via many of these physiological responses, the fatigue an athlete would normally feel is postponed, allowing physical activity to be sustained for longer and of a higher level.
Discussed in more detail later, this is very beneficial to aerobic athletes, where delayed and suppressed fatigue will improve performance. As caffeine targets the brain there are many cognitive effects from using it. Caffeine is a stimulant, so the cognitive benefits from it is that it can reduce tiredness and reaction time.
Usually, sports that require a high amount of cognitive energy tend to correlate to a fine motor skill. Such as darts, pool or chess. In these areas, caffeine can assist by providing greater alertness and feelings of awareness. In gross motor skills, such as cricket batting, volleyball the cognitive aspects of these sports are improved by caffeine for greater awareness. Having a shortened reaction time is also highly beneficial for these sports, such as when the ball is travelling rapidly and a quick response is required to either block or dig the volleyball during a game.
Caffeine is a mild diuretic, which can often lead to dehydration. Other physical disadvantages include, impaired fine motor control, observed via the shakiness of athlete's hands, gastrointestinal upset, increased heart rate and sleep disruptions.
This, on top of the initial rise in temperature due to exercise is disadvantageous, as the human body must work hard to cool the body, via systems such as sweating. Another disadvantage of caffeine is that it can become addictive and to those who don't have a coffee one day will feel edgy and tired, which will worsen their performance, should they be doing exercise.
Caffeine can cause feelings of anxiety and insomnia. Studies have found that sleep deprivation has a significant effect on sub-maximal, prolonged exercise. Although these listed symptoms are cognitive and effect the mental aspect of performance or wellbeing they also lead on to effecting physical performance. Lack of sleep and stress reduces ones ability to perform at optimal level. Caffeine has been proved to be effective for strength and endurance athletes, although greater responses have been gained for the endurance, aerobic athletes.
This is because over the overarching benefit caffeine has for masking fatigue. There is evidence that shows even though caffeine is effective for endurance and anaerobic activities, it is of greatest assistance to trained athletes.
Anaerobic capacity and blood lactate concentration were analysed. Only the trained swimmers increased their velocity after caffeine ingestion, with the p value showing significance.
Temple and A. Ziegler wrote studies that determined the differing effects of caffeine on genders. Males showed greater positive responses, with greater decreases in heart rate after caffeine than females. As well as females showed greater increases in diastolic blood pressure. Endurance athletes have been reported to use caffeine. The benefits caffeine provides may be especially important for low arousal situations. Where a sustained response is required, such as endurance marathons, caffeine improves performance.
Caffeine, when circulating through the body breaks down body fat. The body then has the ability to use free fatty acids as a primary fuel source.
Glucose can be stored as glycogen for later bursts of intense activity. Glycogen sparing is most crucial for the first 15 minutes of the race, so caffeine is likely to be consumed a few hours prior to the event in order to achieve optimal results.
For example, a marathon runner requires energy for 4 to 5 hours. They go through periods of low intensity sustained exercise, in which the predominant energy source is fats. Carbohydrates are also used but are more beneficial if they are stored to use later, nearing the end of the race, hence caffeine improves this glycogen storing process.
Marathon runners must also maintain alertness and energy during the long race. For this reason supplements, such as sports gels are advised and consumed during the race. Typical sports gels contain 26g of carbohydrates with energy boosting caffeine. Anaerobic exercise includes sprinting, weightlifting, and long jump. In studies of trained males the discovery of the optimal amount of caffeine for anaerobic exercise was determined.
J Grgic, E. Trexler, B. Lazinca and Z. Pedisic reported on the testing of caffeine on muscle power and strength, both anaerobic activities. The analysis showed that there were small improvements, in which they discussed for these activities correlate to meaningful differences in performance. From Wikipedia, the free encyclopedia.

The examination of the effect of caffeine supplementation in professional soccer players
Position Statement: The position of The Society regarding caffeine supplementation and sport performance is summarized by the following seven points: 1. Caffeine exerts a greater ergogenic effect when consumed in an anhydrous state as compared to coffee. It has been shown that caffeine can enhance vigilance during bouts of extended exhaustive exercise, as well as periods of sustained sleep deprivation. Caffeine is ergogenic for sustained maximal endurance exercise, and has been shown to be highly effective for time-trial performance. Caffeine supplementation is beneficial for high-intensity exercise, including team sports such as soccer and rugby, both of which are categorized by intermittent activity within a period of prolonged duration. The literature is equivocal when considering the effects of caffeine supplementation on strength-power performance, and additional research in this area is warranted.

Submitted by David F. Vanata, Ph. Caffeine has been identified as a possible ergogenic aid for athletic performance.
The influence of specific training on benefits from caffeine Caf ingestion was examined during a sprint test in a group of highly trained swimmers T and compared with the response of a group of untrained occasional swimmers UT. In light of these results, it appears that specific training is necessary to benefit from the metabolic adaptations induced by Caf during supramaximal exercise requiring a high anaerobic capacity.

Benefits of caffeine ingestion on sprint performance in trained and untrained swimmers
Caffeine is one of the most studied supplements in the world. Studies correlate its use to increased exercise performance in endurance activities, as well as its possible ergogenic effects for both intermittent and strength activities. Recent findings show that caffeine may increase or decrease exercise performance. These antagonist responses may occur even when using the same dosage and for individuals with the same characteristics, making it challenging to explain caffeine's impact and applicability. This review article provides an analytic look at studies involving the use of caffeine for human physical performance, and addresses factors that could influence the ergogenic effects of caffeine on different proposed activities.

Почти через двадцать лет, получив степень магистра математики в Университете Джонса Хопкинса и окончив аспирантуру по теории чисел со стипендией Массачусетского технологического института, она представила докторскую диссертацию- Криптографические методы, протоколы и алгоритмы ручного шифрования. По-видимому, ее работу прочел не только научный руководитель, потому что вскоре последовал телефонный звонок, а затем по почте ей доставили авиационный билет от АНБ. Все, кто имел отношение к криптографии, знали, что о АНБ собраны лучшие криптографические умы нашей планеты. Каждую весну, когда частные фирмы начинают охоту за талантливой молодежью, соблазняя ее неприлично высокими окладами и фондовыми опционами в придачу, АНБ внимательно наблюдает за этим, выделяет наиболее подходящих и удваивает предлагаемую сумму.
