Caffeine versus No Caffeine

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

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

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 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

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’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)

This paper explores and explains the findings of the heart rate experiment conducted by the students of Grand Canyon University for the Anatomy and Physiology 202 Laboratory course. Over a two week time span, students were asked to record their heart rate, before, during, and after activities as instructed by the professor. Specifically, this paper focuses on the female students, comparing the heart rates of individuals who reported that they drink coffee versus those females who reported that they do not drink coffee. The effects of caffeine contained in the coffee were examined and it was noted that those who drink coffee have lower heart rates before, during, and after times of examination. These findings suggested that the hypothesis proposed prior to research, Females Who Drink Coffee Have a Higher Heart Rate Prior to Exams, was an incorrect statement.

This article discusses the affects caffeine has on several aspects of human health. These included toxicity, cardiovascular effects (arrhythmia, heart rate, cholesterol and BP), bone/calcium balance, behavior, and reproductive and developmental effects. It also discussing the affect caffeine intake has on children and reproductive-aged women.

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).

All around the world, people drink coffee, tea and caffeinated drinks to wake up in the morning, to be more vigilant and alert throughout the day. Not only does this keep individuals alert but also allows them to focus and efficiently manage their time throughout their day. This quality of caffeine has caused it to be one of the most highly consumed psychoactive drugs. Individuals who require frequent intakes of Caffeine often feel tired, weak, drowsy if they tend to miss their cup of coffee early in the morning. Although, Caffeine is known for causing wakefulness and alertness it also has its downsides. If a person has a large dose of caffeine in a limited time, the drug could cause them trembling, anxiety and nausea. In long term effects,

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

Caffeine is one of the most popular drink and psychoactive drug in today’s world (Nehlig, 1999). A lot of studies have focused on caffeine with behavior and there was one article by (Smith, 2002) which was explaining how caffeine has been known to increase anxiety after a dose of 300mg or more has been ingested. In an earlier study by Lieberman (1988) it was also proven the caffeine was to reduce depression when in was ingested in moderate doses (Smith, 2002). Many studies have focused with a large consumption of caffeine or with a single dose of caffeine never truly addressing the tolerance of the participants or seeing the long lasting effects of caffeine on the participants (Soar, Chapman, Lavan, Jansari & Turner, 2016). Caffeine is normally seen as a ‘drug’ that can improve our physical and cognitive functions (Hogervost, Bandelow, Schmitt, Jentjens, Oliveira, Allgrove, Carter & Gleeson, 2008). It is known to hold many beneficial effects with fatigue, concentration levels and the skills being applied to physical and mental functions (Hogervorst et al., 2008). It is able to change our central nervous system along with our reaction time for the better, compared to with when there is fatigue our brain and bodies tend to slow down and lose focus on what was trying to be achieve (Smith, 2002). In the Nehlig, (1999) article they mentioned the ‘mechanism of action of caffeine’ where they went over the best concentration of caffeine is usually achieved around one to two cups of

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 is surrounding us these days, and it is in our everyday lives. We see kids with energy drinks and candy bars, and adults with their daily cup of coffee in their hand. “The US Food and Drug

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.
