Caffeine Experiment

From the results obtained from conducting this experiment, it can be observed that caffeine influences blood pressure levels, both systolic and diastolic and causes it to spike up within a short period of time. These results support the research conducted prior to this experiment, which states that caffeine consumption causes blood pressure levels to rise due to a sudden increase in adrenaline and vasoconstriction in the body.

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).

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,

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

Caffeine is a psychoactive drug and potentially deadly in large amounts, especially for adolescents (Hershorin, Lipschulz, Schaechter & Seifert, 2011). Caffeine is one the most common energy drink ingredients and one of the most widely consumed substances in the world. According to the National Institutes of Health (NIH), caffeine is a chemical stimulant compound found in various plants that acts as a central nervous system stimulant. Caffeine is produced naturally and artificially. Caffeine is found mainly in coffee, tea, soda, chocolate, energy drinks and some over-the-counter medications. Due to the increasing demands placed on teenagers today, caffeine is becoming more prevalent in adolescents. While the American Academy of Pediatrics recommends children have no more than 100 mg of caffeine a day due to unknown medical conditions, the fact a teenager’s brain is still in a developmental stage, and the importance sleep plays in the developing brain. Table 1, shows the amount of caffeine for the energy drinks in this report. (Note-this does not include the caffeine from blend ingredients)

Various studies have been conducted in attempts to connect the use of caffeine with increased endurance levels. Graham and Spriet (1995) conducted a double-blind test involving eight endurance runners. Each participated in a control test previous to the study in which they ran a prescribed distance, to the point of exhaustion. All ate similar meals and abstained for caffeinated substances previous to the trials. Over a four-week period, each runner returned to the laboratory to run the prescribed distance while intravenously being given varying doses of caffeine. A blood and oxygen sample was collected every fifteen minutes during the run in order to record the time span until physical exhaustion was reached. The results confirmed that low doses of caffeine caused a drastic increase in endurance levels, while not altering the epinephrine (or adrenaline) levels. Also, large doses of caffeine caused great increases in plasma epinephrine levels while only slightly altering the endurance levels. This test, therefore, supposes that small doses of caffeine, when compared to

The overview and purpose of this article was to explain all common aspects of caffeine, and the affects it has on both professional and recreational athletes. Caffeine looks as if it is involved in multiple areas of the body, so it is hard for scientist to study the specific effects of caffeine on the muscles, the central nervous system and our fat tissue. This article individually explains the findings of caffeine and performance of graded exercise tests, caffeine and

In today’s society, coffee has become the most prevalent and usual source of energization that many individuals turn to when they need vitality. Even though coffee is the most prominent, caffeine can also be found inside sodas, teas, and even energy drinks. Caffeine is a psychoactive drug that stimulates the central nervous system. A typical cup of coffee encompasses about ninety-five milligrams of caffeine. Studies have been performed to observe the effects of caffeine and how it effects so many individuals. For an instance, some studies have discovered that the effects of caffeine may be different for some individuals depending on individual differences such as level of fatigue (Oei & Hartley 2005). These effects lead people to

Caffeine plays an enormous role in society today, from coffee to cokes to candy bars. Companies have made billions off the desire for that extra kick. Caffeine is the most widely consumed behaviorally active substance in the world making it one of the world’s most popular drugs. It’s known for the ability to stimulate the brain and central nervous system. The Chemical structure of caffeine is C8H10N4O2. Before the popular use of caffeine one can assume that people were sleepier, and less alert.

Many people start their day with a cup of coffee. According to John Hopkins, “Around 90 percent of Americans consume caffeine every single day in one form or another”. It seems if we need a wakeup call to our morning, many of us grab caffeine to give us that extra boost of energy. Caffeine is a CNS stimulant drug known as trimethylamine. Caffeine is naturally found in chocolate, coffee, and tea. It is also added to drinks such as soda and energy drinks. Caffeine temporarily blocks the adenosine receptors in the brain. These nerve cells can’t sense adenosine in caffeine, therefore, they maintain their activity and keep us alert.

Caffeine is one of the most prevalent drugs consumed around the world, and is frequently used by athletes in efforts to enhance their performance. It is defined by the Medical Dictionary as “A bitter white alkaloid, C8H10N4O2 that stimulates the central nervous system and body metabolism” (2010). Some believe that increasing their caffeine intake will then improve their energy and endurance levels during long-term sporting events such as running, biking, or swimming. Caffeine is found in an assortment of foods and drinks including but not limited to coffee, tea, cokes and cola products, chocolate and energy drinks. Caffeine can also be found in some over-the-counter medications.

Spriet and Graham,"Caffeine and Exercise Performance”, point out their research on overuse of caffeine. Drugs contain caffeine can cause gastrointestinal discomfort, cramps, insomnia; palpitations should be used in accordance with the prescribed dose. Caffeine effective strengthening of intellectual clarity, and improve thinking ability through blockade of receptors which perform functions adenozyn inform the body needs to sleep. In addition, caffeine also changes some biochemical processes in the body, 2 cups of strong coffee can increase three times the amount of adrenalin in the blood, at the same time accelerate the respiratory rhythm. Caffeine also increase dopamine production stimulating the pleasure centers in the brain, makes people

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

The purpose of this study is to examine the effect of caffeinated beverages (coffee, energy drinks, and sports performance drinks) on an athlete’s quality of sleep, academic success, and athletic performance. Our study will be about how caffeine can affect student athletes sleep which can relate to their academic success, as well as athletic performance. Athletes have a very busy schedule and they use caffeinated beverages to compensate for their lack of sleep. This study is necessary because large amounts of caffeine found in different caffeinated drinks has been said to have a short-lived high of ergogenic effects, which can negatively impact sleep and performance. Focusing on moderate quantities can maximize the effects of caffeine on

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
