Caffeine And Exercise Performance Analysis

(Graham, 1998) This shows the importance of caffeine in endurance sports such as cycling, running, and soccer which require a great deal of physical stamina in order to compete successfully. Studies also show that caffeine has very little affect on athletes requiring quick burst of energy such as sprinters and swimmers. Also caffeine has been known to decrease fatigue in athletes, which plays a physical as well as psychological role in the performance of an athlete.

Caffeine is a natural central nervous system stimulant. It is considered a drug that if is overly consumed can be dangerous for one’s body. Caffeine is a temporary energy booster that improves mood and alertness for most people, mainly athletes. It can be an eye-opener in the morning, could be drunk or eaten on practice brakes, and for some, it just became a habit that they cannot go through a day without a cup of coffee before exiting their doorways. Furthermore, it requires good health and stamina for athletes to perform throughout the game, particularly the one in teams,

Caffeine is a huge component in pre-workout supplements, and is probably the one ingredient that is most controversial. Chemically, caffeine does promote alertness and focus, but the long-term effects and other side effects are what scare most people away from taking additional caffeine to what many people already take on a daily basis. When someone gets tired, it is because of a chemical called adenosine. Adenosine builds up in the brain whenever you are awake, and it binds to adenosine receptors on brain cells. The binding of adenosine causes drowsiness by slowing down nerve cell activity. To a nerve cell, caffeine looks just like adenosine, so caffeine is able to bind to the adenosine receptors in your brain. However, caffeine does not slow down the cell’s activity like adenosine would. The cell cannot “see” adenosine anymore because caffeine is taking up all the receptors adenosine binds to,

The world’s most popular drug is legal, inexpensive, and believed to amplify workouts. It supposedly motivates athletes and helps them stay alert and focused while also boosting physical endurance by twenty to fifty percent. This stimulant is found naturally in sixty-three plants and is consumed by eighty percent of Americans. This white, bitter, crystalline substance is known as caffeine, and is commonly consumed in efforts to enhance athletic ability (http://gopher1.bu.edu/COHIS/substance/caffeine/about.htm).

Caffeine has many negative effects on humans, such as increased heart rate (Lane, J.D., 2002), depression (Goldstein, 2008), and addiction to this “drug.” You may be asking yourself, “What is caffeine?” Well, caffeine is actually a stimulant (Barone, Roberts, 2008) that is found in beverages such as tea, coffee, and soft drinks. In fact, caffeine is the highest grossing and most used stimulant in the United States (Barone, Roberts, 2008). It is estimated that 85% of adults living in the United States consume caffeine on a daily basis (Barone, Roberts, 2008). That means for every 100 adults, 85 of them have had a drink that contained caffeine on any given day. One reason caffeine is so widely available compared to other stimulants is

In 2002, a group of Australian researchers published a paper entitled the "Effect of different protocols of caffeine intake on metabolism and endurance performance". Caffeine use during sporting events has become much more popular and has widely studied. The purpose of the research was to examine the work increasing (ergogenic) effects of differing regiments of caffeine on metabolism and performance while simulating the typical nutritional preparation an athlete would do for a race. The study also sought to examine the effect of timing of caffeine intake, comparing

The painting has been called “a more domestic sort of Eden” because the painter was able to recognize and appreciate God’s creation for everyone to see.

Athletes interested in improving endurance and performance have used caffeine as an ergogenic aid. Caffeine, which is easily available in a variety of foods, drinks and over-the-counter drugs, is a well-recognized stimulant, which has a significant impact on the body. It can improve alertness, concentration, decrease perception of fatigue and perceived exertion, hence used by athletes.

These two drinks have helped millions feel energized, but there are some dangerous side effects. Before sporting events, many athletes choose to have a drink of coffee or an energy drink. These athletes can get these drinks at convenience stores just on the side of the road. Both drinks have a lot of caffeine. Now I'm going to tell you which one is the better choice.

This caused many athletes to begin using caffeinated products in physical sports competition in order to enhance their abilities. The reason that many consider caffeine to improve physical activity is due to the fact that caffeine naturally provides the body with energy and decreasing pain and fatigue. While performing any physical activity the body uses energy that has been stored inside, so with the excess energy provided from the caffeine the body is able to exert more power and energy allowing the physical performer to work longer and with more strength. Decreasing fatigue is one of the other benefits that may aid in the physical performance of the consumer. Caffeine is thought to affect physical performance by stimulating fat oxidation, which, in turn, spares muscle glycogen stores. This means that caffeine is somewhat forcing the body to burn the necessary energy needed to conduct the physical activity from the body’s fat rather than the muscles, this allows the physical performer to continue for longer, farther, and with more force output. If caffeine can decrease naturally occurring pain of exercise and sustain or increase firing rates of motor units, a greater force output should be maintained (Davis 824). It, being caffeine, may also enhance muscle contractions, and increase tolerance to fatigue through the production

Caffeine is a naturally occurring stimulant drug and is commonly found in coffee, tea, chocolate, cola and other products. It is commonly ingested drugs globally and is one of the most studied. Caffeine is a white solid material at room temperature; classified as alkaloid- a nitrogen-containing basic compound that is obtained from plants and has physiologic effects in the body. The number of experimental studies reported increased urination (diuresis) after caffeine intake of 3.4-6 mg/kg/day, which was in some cases associated with increased natriuresis or the excretion of sulfate. Although 6mg/kg caffeine increased urine flows and sweat electrolyte excretion in response to exercise, there was no overall effect on hydration status (Killer,

various studies have looked into the impact of caffeine ingestion on activity execution. The vast majority of them for the most part infer that caffeine utilization before working out appears to broaden continuance execution amid tolerably strenuous vigorous activity. The principle proposed instrument for this change is the expanded utilization of fat as fuel. On the other hand, there is by all accounts advantage errors between constant caffeine clients and non-chronic clients. When a certain level of resistance is come to, the ergogenic impact of caffeine may be lessened (Roberts,2003).

Thesis: Caffeine can have many different effects on the body depending on the amount of consumption.

When caffeine enters your bloodstream, it will block the receptors of adenosine, a quieting neurotransmitter that tells your brain when it’s time to sleep. This will result in your brain becoming hyperactive and lead to an increase in levels of epinephrine, a “fight or flight” hormone in your body that will cause an increase in heart rate, blood circulation to muscles, and sugar release from the liver into the bloodstream for energy. As a result, caffeine will in fact stimulate your brain and provide a perception of increased energy after consumption. A runner who may expend a lot of energy on one of his/her jogs may need the extra energy from sugar and caffeine to keep the cells in their muscles working to aid their endurance. Studies to date have shown that consumption of 3-9 mg of caffeine before physical activity may improve endurance running and cycling in athletes; others have shown that caffeine consumption improved memory and reasoning responses on tests. However, a can of Impulse contains only 88 mg of caffeine, whereas a cup of coffee contains up to 200 mg. Why opt for Impulse when you can get more bang out of your buck with a cup of coffee?
