Caffeine Retention Paper

Caffeine is a wildly use drug in today’s society. Caffeine is a methylated xanthine which acts as a mild central nervous system stimulant (MS & RL, 2001). It is a stimulant which acts upon the central nervous system and increases alertness, wakefulness and restlessness and it increases the release of catecholamine from renal medullar (Fernandez, 2016; Collines, 2007). It is present in many beverages. Caffeine is found in coffee, tea, soft drinks, products containing chocolate (cocoa) and some medication (Collines, 2007). It is used as a cardiac and respiratory stimulant (Collines, 2007).Caffeine is the most frequently ingested pharmacologically active substance in the world (Collines, 2007).

Taurine helps people get more awake with less fatigue so it helps people get more energy from it. In conclusion the barry Meier does not get his claim enough evidence and the wrong evidence to believe that energy drinks don't give you energy. The examples he gave were

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,

An independent samples t-test was conducted to examine the difference between experimental conditions on test performance. The results indicated a significant difference between participants who consumed the caffeinated beverage and participants who did not, with participants in the caffeinated group (M = 7.64, SD = 2.41) performing worse than participants in the non-caffeinated group (M = 9.81, SD = 3.16), t (97) = 2.14, p < .05.

The behaviour of caffeine acts as a stimulant which increase brain memory. Caffeine belongs to the xanthine chemical group that has an influence on the central nervous

Caffeine’s mental appeal is just as trendy as its physical purpose. Caffeine has been proven to stimulate the central nervous system. Caffeine stimulates the Central Nervous System at high levels, like the medulla and cortex, and even has the ability to reach the spinal cord in larger doses. The effect of caffeine in the cortex is a clearer thought process and also can rid the body of fatigue. This gives people a greater ability of concentration for 1-3 hours. For athletes competing in sports where quick thinking and rapid reactions are necessary, caffeine can provide a huge edge. However, these results are much more inconsistent than the experiments done on caffeine in endurance sports. (http://www.garynull.com/Documents/CaffeineEffects.htm)

Caffeine is an ‘alkaloid’ (Farlex, 2003) and according to Spriet, 2014, is commonly used ‘work enhancing supplement’ which has been researched thoroughly since the 1970’s, due to caffeine’s potential to improve performance through its ergogenic effect. Caffeine’s ergogenic effect targets the CNS, as caffeine is a ‘adenosine antagonist’ (Davis et al., 2002; McCall, Millington, Wurtman,. 1982) Caffeine has a very similar structure adenosine (Fredholm, B, B et.al., 1999) which enables the caffeine to pass through the blood brain barrier (McCall, A.L., Millington, W.R. and Wurtman, R.J. 1982) and block the adenosine receptors and therefore delays the onset of fatigue (Graham, 2001) and create a greater sense of wakefulness and alertness while also improving reaction time. This is achieved throught the blocking of the adenosine receptors

Research by Smith 2001, shows that he found that cognitive performance over the course of a working day was improved more in people who consumed above average amounts of caffeine than those who consumed less than average.

Caffeine does not usually have an affect on memory. When you drink caffeine at a low

The consumption of caffeine can increase alertness, reaction speed, vigilance, the ability to concentrate and problem-solving ability; all the things Red Bull Energy Drink also claims to do (Red Bull 2013).

Caffeine, however, is the most common stimulant. “Caffeine is the most widely used drug on the planet and has been used for centuries for its stimulating effects” (energy fiend.com). Most energy drinks contain between seventy to two hundred milligrams of caffeine each. For example, a full can of Rockstar contains one hundred sixty milligrams of caffeine. Caffeine stimulates the central nervous system, which gives the body a jolt of their senses, making them more alert. The use of caffeine can dehydrate the body and raise blood pressure and heart rate. Symptoms can commonly occur from consuming caffeine such as, heart palpitations, headaches, nausea, and the jitters. Taurine is an amino acid that is naturally produced by the body. Our body usually creates enough of this so you do not need a supplement. It is said to help with regulating the heart beat, energy and muscle contractions. A long time ago the use of taurine was banned in certain countries, but that ban has been lifted. The ingredient gaurana comes from a plant in South America. Some people say that gaurana works better than caffeine for an energy boost, but there are not many statistics on the fact. The last of the five common ingredients is all of the B vitamins that are used. These vitamins are pretty much the items that help you transform food into energy. The Vitamins B6 and B12 do not absorb well when you swallow them. Typically the amounts of B vitamins used in most of the energy drinks will have no

According to Smith (2001), he found that cognitive performance over the course of a working day was improved more in people who consumed above average amounts of caffeine than those who consumed less than average (Smith 2001).

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

Taurine is found in many energy and sport drinks because under stressful situations, taurine is eliminated from our body without being replaced quickly enough. Taurine has no proven side effects but “may counteract the effects of caffeine in energy drinks” 7.

It has in fact been found that intake of caffeine may enhances the physical performance however there is no linear relation between the amount of caffeine consumed and the performance. It is evidenced that caffeine is able to enhance different types of performance when consumed in low or moderate doses (3-6 mg/kg), whereas higher doses provides no further benefits. It is evident that caffeine enhances the performance during high-intense exercises for a longer period of time, the impact of caffeine is however not identical in all individuals and the effect on the performance depends on the athletes. There are reported no significantly difference of the impact of caffeine on individuals habitually caffeine consumers and non-habitual caffeine
