Caffeine versus No Caffeine

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 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.

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 the fast paced life of a college student, it is not uncommon for tasks and due dates to quickly pile up, demanding more hours studying and less hours sleeping. Any amount of sleep deprivation can lead students to consume caffeinated beverages, particularly coffee, to help them stay awake and get their work done. According to the University of Michigan (2015), Caffeine acts in the body by effecting the central nervous system and may start to

This experiment studied the effects of caffeine on the reaction time of a number of students. It was done with 12 individuals who all selected their own source of caffeine to use for the testing. The three main caffeine sources were V energy drink, coffee and red bull. The reaction times of these students were recorded before and after drinking the caffeine in order to obtain results on the effect that caffeine had on the individual. This was done by using an online reaction test where students were to click on a button each time the green traffic light appeared. The results indicated significant differences in the reaction times of the students’ pre and post caffeine intake. Therefore, the experiment showed that caffeine did have an impact on the reaction time of the student after consuming caffeine. This report allows comparison of the mean scores of the 12 groups using tables and graphs to clearly indicate the differentiation of each result.

Caffeine can result to higher blood pressure, can increase body’s heart rate and metabolism.

Ever stay up late studying for a test or exam and wake up exhausted? Or just experienced a long day and need an extra boost? Many people believe caffeine is the answer to anyone’s drained state of being. Healthline.com explains that, “Caffeine reaches your brain quickly and acts as a central nervous system stimulant.” Caffeine is commonly referred to the most widely used drug on the planet, so the next question is which caffeine-filled product is the most efficient? It is widely debated whether energy drinks or coffee can provide the best balance of caffeine, flavor, and other ingredients, but after researching, I have come to conclude coffee is superlative in all aspects.

Due to the increase of the sampling size and finely divided groups, the result can accurately point out the effect of caffeine towards people with the different physical condition, and thus showing a more precise effect from the result. There are studies stating that significant effect of caffeine to aerobic performance may be only showing on the trained individuals but not the untrained ones as the untrained ones do not get any ergogenic effect after getting caffeine (Hoffman,

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.

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

One on the beneficial effects on caffeine, two the negative effects, and finally on trends in caffeine consumption

Thesis: Caffeine is something that almost everyone has consumed and some people are even addicted to. Caffeine has negative and positive effects on one’s health

Coffee urine osmolality followed the same trend as control urine osmolality by remaining constant with increasing post-consumption time. Soda urine osmolality differed from control urine osmolality and soda urine osmolality by decreasing with post-consumption time. Also, soda urine osmolality was lower than both control urine osmolality and coffee urine osmolality at all collections times. Coffee heart rate followed same trend of control heart rate by generally decreasing with post-treatment time. Soda heart rate differed from control heart rate and coffee heart rate by increasing with post-consumption time. Coffee heart rate was significantly higher than both control heart rate and soda heart rate 30 minutes after treatments. Soda heart rate was higher than control heart rate and coffee heart rate at 60 minutes and 90 minutes after treatments. These results are important to our understanding of the effect of caffeine on the human

Caffeine is one of the most consumed psychoactive substances around the world. Caffeine is not bad for health, some researchers even show positive effects. Caffeine appears to reduce fatigue. And in this way also has an indirect effect on decision. Regarding cognitive function, caffeine has an effect on reaction time. Some studies also show a positive effect on long-term memory.
