Caffeine Manipulation
The past research increases validity of the current research by eliminating the possibility of not
having enough caffeine manipulation to cause an effect. 32 mg is less than what you would find in a
normal cup of coffee, assuring that if any effects were not seen, that it was not due to an insufficient
dosage of coffee. However the previous work does not show data on more voluntary cognitive
processes that the current experiment tests upon as stated previous. The past study measures reaction
times based on auditory and visual techniques, which are instinctive versus a task requiring more
thought process. The previous experiment does shed light on valuable data in dosing, that the current
experiment will not test.

In addition to the benefits caffeine has on the body, there have been studies completed to see the
effect of caffeine on the performance of athletes especially in terms of increasing endurance. Many
athletes try to improve their endurance through various methods such as eating high carb meals prior
to competitions. Some athletes also drink large amounts of caffeine in order to improve their
endurance through energy drinks or caffeinated beverages hoping to eliminate the fatigue from the
sport. The results of some studies have shown that ingesting caffeine prior to exercising in a sport
will extend endurance in moderate aerobic activity; other studies showed that caffeine consumption
on elite distance runners and swimmers can increase their performance times. Even though there are
some studies to show effects on endurance, another study showed that caffeine did not produce any
effect on maximal muscular force when studying voluntary and electrically–stimulated muscle
actions. However, the data gained from that study did show that it has the effect of reducing muscle
fatigue on muscles during repetitive motions. Furthermore, caffeine does have documented positive
effects to improve performance. Because of the effect of caffeine, the International Olympic
Committee banned athletes from performing with 12 mg/mL or more of caffeine in urine tests. In

Caffeine And Its Effects On Caffeine
Introduction: Have you ever experienced the jittery feeling after drinking too much pop or coffee?
You're suddenly filled with tons of energy and sitting still feels almost impossible. You have most
likely experienced this feeling whether it be from eating too much candy, or having too many
caffeinated, sugary drinks.
Attention Getter: Many of you probably drink pop, coffee, or other drinks containing some amount
of caffeine. Caffeine has become more and more common, and most people don't think too much
about it. Even if you only rarely consume caffeinated drinks, it's still important to know what these
drinks are doing to your body.
Listener Relevance Link: Personally, I drink a lot of coffee and tea throughout the day, and I was
wondering how this is effecting me, besides just giving me a little extra energy.

Caffeine is a common central nervous system stimulant drug which occurs in nature as part of the
coffee, tea, yerba mate and other plants, can be said to be the most psychoactive substance in the
world. ( Fredholm et al. 1999). It is also an additive in many consumer products, most notably
beverages advertised as energy drinks. Caffeine can also be found in soft drinks such as Coca–Cola
and Pepsi, where, on the ingredients listing, it is designated as a flavouring agent. It is regarded as
the most widely consumed stimulant drug in the world based on Nehlig, Daval, & Debry (1992)

It is now widely accepted based on available scientific data that only one or two cups of coffee are
enough to facilitate the action of caffeine in the circulatory system. The many effects of
methylxanthines can be said to be attributed by the translocation of intracellular calcium, the action
of blocking adenosine receptors and increasing the accumulation of cyclic nucleotides (Ashihara et
al., 2008). There is the lack of evidence to show the ability of methylxanthines to block cyclic
nucleotide phosphodiesterases. A high concentration of caffeine interferes with the calcium uptake
and storage by the sarcoplasmic reticulum. This explains why intake of caffeine strengthens and
increases the duration of cardiac and skeletal

Caffeine Adaptation
Caffeine is the most widely consumed central–nervous system (CNS) stimulant in the world. It is a
commodity that people use to boost their adrenaline and increase their metabolism. Caffeine
executes this by increasing the calcium in the brain. While caffeine's pharmaceutical effects have
been studied by many organizations such as the FDA, no studies have been conducted to assess
caffeine's role to induce endurance like adaptations. These adaptations include increased
vascularization, mitochondrial biogenesis, and increased oxidative capacity. Specifically, caffeine's
effect on calcium concentrations ([Ca2+]) on the body's muscular intracellular components and the
stimulation of Calcium / calmodulin–dependent kinase (CaMK) has not been studied. It is now
known that calcium enhances the calcium–sensitivity of the ADP–ribose–sensitive calcium release
channels. This releases intracellular calcium levels in the sarcoplasmic reticulum and the
endoplasmic reticulum in cells, specifically neuronal cells. Studies conducted by DeLorenzo, et al.,

The most efficient way to acquire energy is through high levels of mitochondrial biogenesis and
increase in Ca2+ concentrations. Greater concentration of mitochondria and Ca2+ will provide
athletes the sustainable energy needed to cause muscle contractions. In addition, continuous exercise
induces muscular intracellular and calcium concentrations. These muscle contractions are generated
via the transmission of action potentials (AP) through the alpha motor neuron, and once transferred
to the muscle fiber increase cytosolic Ca2+. Contractions result in larger levels of intracellular
Ca2+, and more activation of CaMKII will efficiently generate these contractions; thereby, reducing
the amount of muscle tissue the body damages to produce the energy it needs (Ojuka et al., 2003:

Caffeine Is A Substance Of Caffeine
Caffeine is a substance that occurs naturally in certain plants, Caffeine can also be man–made, and it
is added to many substances. Caffeine is one of the most commonly tested ergogenic aids
(substances that enhance an individual 's energy use, production, or recovery) and is known to help
athletes improve their performance allowing them to train harder and longer. Caffeine stimulates the
brain and contributes to clearer thinking and greater concentration.
WADA (World Anti–Doping Agency) are observing the usage of caffeine by athletes, because it has
been seen that since its removal from the prohibited list, its use has dramatically increased. Though
the substance still holds performance enhancing effects the WADA have the choice of reinstating
their ban our lowering the permitted amount before a sporting event. If the ban where to be
reinstated it would be difficult for athletes as caffeine remains in the system for 48 hours after
consumption therefore allowing for zero caffeine in that time period before a race.
The recommended maximum daily intake for most healthy adults to consume up to 400 milligrams
of caffeine per day which can come in the form of coffee, medication and other substances. How
much caffeine each beverage contains varies a lot, so it is near impossible to know the exact amount
that is being consumed. There's also a great variation in the amount of caffeine an individual can
tolerate without unpleasant side effects.

Caffeine Addiction
Addiction is a disease that causes individuals to be compulsive and seek for substances in order to
relieve craving. Addiction is commonly associated with drugs and is a great concern to the well
beings of people around the world. The physiological and psychological effects of drug addiction
can be deadly. Mood swings, hallucinations, and confusion are common physiology side effects,
while psychological effects include inevitable depression, cravings, paranoia, and anxiety. By
researching and gathering more data about substance addiction, it could lead to a decrease in the
number of deaths associated to drug abuse and find healthier alternatives.
Prominent drugs that are widely recognize are heroin, tobacco, alcohol, and meth. However, the
most widely consumed addictive substance that tends to get overlooked is caffeine. About 83% of
the world drink caffeine in one day. Many individuals rely heavily on its effect in order to perform
daily tasks. Unlike other psychoactive substances, caffeine can be obtained legally and the
government does not regulate its production in most parts of the world. Caffeine is a prominent
ingredient in a variety of products including coffee, soda, energy drinks, and some over–the–counter
medications. All these products can be easily purchased at a convenient store, which is why caffeine
is the top consumed additive substance. Since caffeine is cheap and readily available, the chance of
consuming and getting addicted is high. Researchers have

Memory gives us the ability to learn and adapt from previous experiences as well as to build
relationships. Scientists outlined three stages of memory which are sensory memory, short–term
memory, and long–term memory (Cherry, n.d.). The stage model of memory is often used to explain
the basic structure and function of memory. Sensory memory is the earliest stage of memory. During
this stage, the information from the environment is stored for a very short period of time. Short–term
memory, also known as active memory, is the information people are currently thinking about. The
information that stored in short–term memory will be kept for approximately 20 to 30 seconds, and
are quickly forgotten. Long–term memory refers to the continuing storage of information. The

Most people aren't aware that caffeine can act as a stimulant to the central nervous system. So once
someone consumes a caffeinated beverage they may begin to notice a slight change in the way their
body begins to feel. Caffeine can be found in many different places such as energy drinks, coffee,
candy and also in other common beverages and over the counter medications. Caffeine can have
major side effects on those who consume it on a regular routine, but caffeine can also have side
effects on those who rarely even consume caffeine . "These side effects include sleep deprivation,

(Berger 58)." Not only can caffeine have a bad effect on your diet it can also have major effects on
your brain. Caffeine can increase the rate of neuron firing in the brain, and it blocks adenosine
receptors in the brain which keeps people feeling alert. "It works differently on different people with
different tolerances (Berger 63)." People who consume large amounts of caffeine on a regular basis
can suffer a change in the brains chemical makeup which make it even more difficult for someone to
quit. After 24 hours of attempting to quit the substance the withdrawal symptoms begin. Someone
may notice things become foggy, and lack alertness. Why, exactly, is caffeine so addictive? It is
basically so addictive because of the way the caffeine reacts with the brain. Soon after caffeine is
consumed it heads to the small intestine and absorbs it is then transferred to the bloodstream, and
from there it can enter the brain. When someone ingest caffeine is said to be like "putting a block of
wood under one of the brains primary brake pedals (Braun 65)." The block could remain there for
about six hours depending on how old the person is, how much they weigh, and also how often the

The module for this week will be about caffeine. I thought it would be a good idea to provide some
basic information about caffeine. Many of us have caffeine as part of our daily routine. An example
of this would a cup of coffee, an energy drink or soda. The question that ran through my mind, is,
how much caffeine should you have? The answer to this is no more than 500 milligrams a day. Have
you ever considered the amount of caffeine that you brew or buy at a coffee shop? According to
Mayo Clinic, "the actual caffeine content of the same coffee drink can vary from day to day–even at
the same coffee shop–because of various factors, such as roasting and grinding as well as brewing
time" (2014). My go to coffee place is Starbucks. When I go there, I know exactly what I am going
to order, a venti iced caramel macchiato with light ice. If I am tired, I may ask to add another shot,
but other than that I don't ever think about the caffeine amount in that drink. I don't think about how
it is grinded, or how it is roasted. I order, I pay, and I drink. For me, coffee is part of my daily
routine. I enjoy the smell and the taste. I would consider it as a morning ritual. With coffee, the type
of coffee (how it is brewed, where you get it) impacts how the amount of caffeine in that drink.
According to an article published by Mayo Clinic Staff (2014), lists the amount of caffeine for
different types of coffee, tea, soda, and energy drinks. An 8 oz. brewed coffee contains 95–200

The story says that a farmer noticed his cattle acting ancy and relentless, a few days later he went to
check on them and found berries they had been chewing. These beans had been later dried and
renamed "coffee beans", which is a very popular association today between caffeine and users. As
stated from this story, the first discovery of anything with caffeine was the coffee bean. Humans
have consumed caffeine since the stone age. "Early peoples found that chewing seeds, bark, or
leaves certain plants had the effects of easing fatigue, stimulating awareness, and elevating moods."
("Science"). Ever since this time, the people who consumed it knew the effects it would have on
your body. By the early 1500's, caffeine was used regularly to stay awake for nighttime rituals.
When this was going on, people into the community started to get suspicious. The ruler of the
community banned coffee completely, but didn't let it last long because the people of the town were
so outraged. In the 1980's, the FDA considered taking caffeine out of all soft drinks. Companies
argued that it was a flavor enhancer, so it should be allowed, and they won. "If caffeine had not been
accepted as a flavor enhancer, but had been regarded as a psychoactive ingredient, soft drinks might
have been regulated by the FDA as drugs." (Chicago Tribune). This is an ongoing struggle
everywhere in the world, and it needs to be addressed more. As I stated before,

system consists of the heart and the blood vessels that circulate blood throughout the organism's
body. Blackworms do not possess a respiratory system or a heart, thus they circulate their blood
through contractions of the blood vessels. The pulsation rate was observed along the dorsal blood
vessel near the posterior end of the worm to give better readings. The various drugs were exposed to

1). Another study shows that nicotine stimulates the adrenal medulla to secrete hormones such as
epinephrine and norepinephrine which are responsible for the increase in the pulsation rate (George,
"Effects of smoking on cardiovascular function: the role of nicotine and carbon monoxide", 2015,
pp. 278–280).
Methods
The experiment was conducted using six worms, where three were used for one treatment and the
other three for a different treatment level. Initially, the worm was transferred to a parafilm slide
containing some water and placed under a dissecting microscope. Application sticks were used to
place the worm on the mark and an additional light was placed to observe. The focus was on the
posterior end of the worm to obtain the basal pulsation rate. A timer was used to record the basal
pulsation rate for 15 seconds, then the result was multiplied by 4 to get the number of beats per
minute and this was repeated for two more trials. Same methods were used to measure the pulsation
rate of two additional worms and the data were recorded. Next, the same three worms were removed
from each slide and placed inside three vials containing nicotine at a concentration of 0.05mM. The
worms were placed for 15 minutes and then were transferred sequentially to the parafilm slide to be
viewed under the dissecting microscope. The pulsation rate was recorded for 15 seconds, then
multiplied by 4 to get the number of beats per minute and this was repeated for

minute were calculated and the same amount was used for the caffeine test. The shrimp was allowed
to destress in between the tests and was finally placed in water with 2000 µL of acetylcholine and
2000 µL of caffeine. The results demonstrated that compared to the average baseline heart rate, 196
beats per minute, the caffeine increased the beats to 230 while the acetylcholine decreased the beats
to 158. Together the stimuli produced an average of 200 beats per minute and produced the closest
heart rate to the baseline. The statistical t test scores for acetylcholine, caffeine and in combination
were 0.083, 0.029 and 0.37 respectively. These scores demonstrate that acetylcholine and the

Not only it is a major component for bones in humans, it also serves other vital roles. Caffeine also
may contribute to loss of bone by increasing calcium excretion and also a decrease in intestinal
absorption efficiency of calcium (4). Calcium provides structure and hardness in bones and teeth, it
allows muscle to contract and nerves to send signals, makes blood vessels expand and contract,
helps to move blood clots, and it also plays a roles in supporting protein function and hormone
regulation (3). Knowing calcium role, it is easy to see how it can lead to a decrease in bone density.
Inadequate calcium intake can lead to decreased bone mineral density, which can increase the risk of
bone fractures (13). A few ways an agent may increase fracture risk and/ or skeletal fragility include
an interference with the bone remodeling process designed to detect and repair fatigue damage in
bone structures and also a decrease in bone tissue mass either generally or in key architectural
elements (12). Osteoporosis is a medical condition, in which the bones become brittle and fragile

The Consumption of Caffeine
From coffee to tea, caffeine has become a prominent substance that people use to keep them alert
and productive. Considering the number of people that consume more and more amounts of caffeine
each day through different means, it has been integrated into daily lives as a part of a routine.
However, many people do not comprehend what caffeine is actually doing to their bodies, and they
just consume it for the energy boost it provides. Primarily used as a stimulant, caffeine has proven
itself in the course of history as a beneficial component of daily routines, despite the fact that
repercussions have become more prevalent in the past years surrounding the use of caffeine.
The spread of caffeine is documented throughout history in many different countries and in many
different forms of the substance. In 1819 after a rendezvous with Johann Wolfgang von Goethe, an
affluent member of the upper class, Friedlieb Ferdinand Rung, who was a junior doctor at the time,
identified the chemical caffeine (Weinberg and Bealer xvii). The abundant elements nitrogen,
oxygen, hydrogen, and carbon are what make up the molecular structure of caffeine (Weinberg and
Bealer 216). Consequently, when an individual ingests caffeine, it subdues the adenosine receptors
which if not inhibited would diminish bodily actions, however, due to caffeine's effect on the body,
it yields a pick–me–up reaction (Gilbert). Generally speaking, individuals who consume caffeine in
the United States get their caffeine

Caffeine Synthesis
Caffeine is a stimulant drug and the most widely–consumed mid–altering substance in the world.
Most of the effects of caffeine are thought to be traceable back to its action as an antagonist at
receptors for adenosine, a neurotransmitter. Caffeine binds to adenosine receptors and blocks
adenosine from binding there and activating the receptor; thus, it reduces activity at the adenosine
receptor. Although there are four subtypes of adenosine receptor, most of caffeine's effects are
thought to be due to its antagonistic actions at the A1 and A2A subtypes. Its ability to produce
wakefulness may be especially due to actions at the A2A receptor subtype. How exactly the
antagonism of the adenosine receptor translates into the effects of caffeine

physical well–being, but psychological well–being as well. Caffeine addiction can lead to sleeping
disorders, anxiety disorders, and in some cases, a type of caffeine intoxication. Some argue that
caffeine addiction is one of the least harmful addictions, and they excuse their dependency by
considering that there are worse things in the world that they could become addicted to. However,
people who fail to acknowledge that they have an addiction, may not be prepared to experience its
lasting effects on their health. Often, people who are dependent upon caffeine do not recognize if
they have a bigger health concern, they blame any fatigue or illness on either lack of caffeine, or too
much caffeine. Caffeine only takes somewhere around half an hour to start having its effects on the
body and brain. After these effects are processed by the body, it builds up a certain amount of
tolerance which causes people to crave more

Essay On Caffeine
Can someone tell me why they drink coffee? Well, most people think of it as a powerful drink that
gives them energy whenever they need it. I am here to tell you that coffee works a lot differently
than most of us think. It does something completely different than what you might expect to your
body. And coffee is not the same for everyone, to some living things it's even poisonous. Even its
name is deceiving because coffee is not even a bean at all. I am not here to dissuade you from
drinking coffee, but rather inform you about how coffee affects us and how our bodies deal with it.
So next time when you chug down a cup you should know what you're doing to your body.

Melatonin is a hormone that makes us drowsy, it's activated by the time of the day, light exposure,
and many other things. The more melatonin in your body the sleepier you are going to be. But an
important part of your sleeping process is adenosine. Adenosine is released periodically hour by
hour building in your system. And when you go to sleep adenosine breaks down and begins the
whole process again in the morning. Now the reason adenosine is so special is because it's a neuro–
depressant. When it attaches to your receptors, it slows down neuron activity which makes you more
sluggish and tired over the day. It naturally works with melatonin to put you to sleep. Now because
your sleep cycle is a very delicate process, the things you do can highly affect your sleep. The color
of your room can affect how fast you go to sleep and if that sleep made you tired in the morning.
Right now, caffeine seems like it has nothing to do with your sleep cycle. But it actually has a lot to
do with it. Caffeine and adenosine have identical binding structures (show nitrogen rings) which
means when you drink coffee, caffeine binds to those adenosine receptors and stays there. But
because caffeine has no effect on your neurons it just stays there taking up space. Well, then what's
the problem? Because caffeine is taking up the receptors which are meant to bind with adenosine,
adenosine

Effects of Caffeine
Effects of Caffeine Caffeine has been a hot topic in the medical community as of late. Studies have
shown that the effects of caffeine are undoubtedly beneficial to people's health. However, other
studies have shown that its effect can have a negative impact on health. So what is caffeine and
where do you find it? According to Merriam–Webster's dictionary, it is "a bitter alkaloid
C8H10N4O2 found especially in coffee, tea, and kola nuts and used medicinally as a stimulant and
diuretic," (Merriam–Webster). It can be found in foods such as chocolate, cappuccino frozen yogurt
and mocha cheesecake. Surprisingly enough, it can also be found in beverages such as Sunkist
Orange Soda, Mountain Dew and Jolt.

2). However, the benefits outweigh the negatives, according to Flora (par. 10).
So how do we know just how much caffeine we ingest on a daily basis? The average consumer will
never know exactly how much they take in since food and drink manufacturers are not required to
list how much caffeine their product contains on the nutritional label, (Hitti, par. 5). Mann notes that
an eight–ounce cup of coffee contains about 135 mg of caffeine, an eight–ounce cup of tea contains
50 mg, 12 ounces of Coca Cola contains 34.5 mg and 12 ounces of Diet Coke contains 46.5 mg (par.
11). The average habitual user of caffeine takes in approximately 200 mg of it daily (Mann, par. 10).

LITERATURE REVIEW
Caffeine has a long history of consumption. It was first found in the form of coffee which was
discovered around 1,000 years ago in the region now known as Ethiopia. The first coffee shipment
to Europe was around 1615. Rapid growth of popular coffee houses spread from the mid–17th
century as they became favourite meeting places. Till to date, it is the world's most widely
consumed psychoactive drug. It is legal and unregulated in nearly all parts of the world, unlike many
other psychoactive substances. Caffeine, a bitter substance found in coffee, tea, soft drinks,
chocolate, kola nuts, and certain medicines (MedilinePlus, 2015), is a central nervous system
stimulant of the methylxanthine class. Caffeine intake is so common ... Show more content on

The Harvard study also found that regular coffee drinkers were 80 percent less likely to develop
Parkinson's disease, 20 percent less likely to get colon cancer, 80 percent less likely to develop
cirrhosis, and 50 percent less likely to develop gallstones compared with those who did not consume
caffeine (Brain, 2000). Caffeine is also being studied further for its potential benefits in battling
Parkinson's disease, Alzheimer's and cancer (Brain, Bryant & Cunningham, 2000). Recent studies
have found that coffee consumption decreases depression among women (Aubrey, 2013). According
to Jack Bergman, a behavioural pharmacologist in the department of psychiatry at Harvard Medical
School, caffeine has rarely been abused. He also mentioned that overuse of caffeine tends to stop
itself. The user would naturally stop consuming caffeine after getting jumpy and uncomfortable
from consuming too much caffeine. Looking at all of the studies on caffeine and its effects, it is not
exactly proven to be dangerous to human's health, however, moderate consumption is advisable.
Like any other edible stuff, caffeine also comes with good and bad attributes, depending on how it is

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.
The results from Graph 1 and Graph 2 clearly show that there was a very large spike in systolic and
diastolic blood pressure, which occurred between the 20–30 minute marks. This pattern is consistent
throughout the 5 days, which supports the research conducted by Harvard University that caffeine
causes an increase in adrenaline and therefore, blood pressure in the body. It is also to be noted that
the spike in systolic blood pressure increased as the dosage of caffeine increased, except for the
114mg serve of caffeine, which had a larger increase in blood pressure than the 142.5mg serve. This
could have been due to the surrounding conditions of the consumer since although the starting ...

This spike only lasted for 5–10 minutes, whereas the spikes caused from the 114 and 142.5mg of
caffeine lasted for approximately 10–20minutes. This could have been due to the fact that in an
average cup of instant coffee, there is approximately 95mg of caffeine. Since the doses of 28.5mg

much of a strong effect on the body and once the consistent activity for the hour began, in this case

The brain has receptors in it that a chemical called adenosine binds to; adenosine is a small chemical
in the brain that causes the person to feel tired or sleepy (Olekalns and Bardsley). Caffeine has a
very similar shape to adenosine; it goes in and blocks the receptors that adenosine originally binds
to. This is why after drinking a big cup of coffee the body feels awake and more alert. A person's
body can function without caffeine completely with no negative effects. In moderate amounts
(250mg daily) it can have a pleasant feeling for the user. Furthermore it causes the pituitary glands
to release adrenaline, which heightens the senses. Since caffeine causes a bit of an adrenaline surge
in the body, someone's physical output is much higher. (Olekalns and Bardsley). Having the body in
a jumpy state for a whole day after many cups of coffee or energy drinks is not very healthy for the
body or the heart. (Olekalns and Bardsley)
Also caffeine has a track record of do nots for people trying to live a healthy lifestyle. It always
points back to the negative effects on the nervous system. (Olekalns and Bardsley) The body weight

It occurs when a chemical does from something really hot to really cold quickly, at a low pressure. If
the pressure were to increase then the solid would become a liquid and then a gas. When it actually
came to the sublimation part, the crude substance of caffeine, was put over a heat source at high
degree of heat, around 200 degrees Celsius. The vacuum pipe was attached to the side of the tube,
and it worked to control the pressure within the tube. In the middle of the tube was the most
important part. There was a smaller tube (cold finger) placed, it was filled with ice cold water to
ensure that the gas would sublime, and when it came in contact with the ice cold tube, white caffeine
crystals would form. To ensure that no water got into the tube where the crude substance was, we
used saran wrap to block it. If water had gotten into the crude caffeine tube, then the caffeine would
have dissolved. We also had to be careful when taking out the inner tube that had the caffeine
crystals as they were

The Benefits Of Caffeine
In the late 17th century, coffee was spread throughout the world and was produced for commercial
usage for the first time. Emil Fischer, a German chemist was the first to separate Caffeine in 1895
from plant extracts.
Caffeine is now the most widely used stimulant in the world. It is a stimulant in humans and is
mostly distributed through drinks including tea, coffee, soft drinks, and chocolate. (Gilbert, 2012)
Caffeine's chemical name is 1,3,7–trimethylxanthine, based on its formula, C8H10N4O2, and
molecular structure. Caffeine is the most used psychoactive drug worldwide. It is also a natural

Benefits of caffeine include preventing diseases like stroke and certain cancers, lowering the risk of
Parkinson's and dementia, as well as boosting concentration and memory skills.
However, caffeine can react poorly with some medications and it can worsen insomnia, anxiety, and
heartburn. Caffeine is a drug and too much of it can cause addiction, severe headaches and a rise in
heart rate or blood pressure.
Side effects of caffeine include headaches when too much caffeine is consumed or due to a sudden
stop in consumption. Other effects of an overdose include confusion and hallucinations or even
death due to convulsions. Caffeine raises the concentration of acid in the stomach and may cause
heartburn or an upset stomach. Rapid or irregular heartbeats and breathing difficulties could also be
due to an overdose. (Sagon, 2013)
The function of caffeine is to stimulate or excite the brain and nervous system, thus many people

The Effect Of Caffeine On Caffeine And Endurance Performance
In this literature review, I will be analysing the literature on Caffeine Ingestion and Endurance
Performance.
Endurance performance according to Farlex, 2003, 'is a performance where key muscles are
exercised at submaximal intensity for prolonged periods of time', without the onset of fatigue.
Caffeine is a, stimulant which affects the central nervous system (CNS) (Farlex, 2003) and it has
also been found to increase the fat oxidation and metabolism of free fatty acids, FFA, (Essig, Costill,
and Van Handel, 1980; Hadjicharalambous et al., 2006), during aerobic respiration through the
release 'epinephrine' as stated by Spriet et al., 1992.
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

Within the experiment, the team administered 200 milligrams of caffeine to a select number of
patients while the remaining were given a placebo (Borota et al). A placebo, in experiments are pills
that have no effect on the user. The placebo recipients were under no effects while the caffeine
recipients got a boost to their ability to recall long–term memory. This was expected given that they
have no effect on the individual. This was crucial for the experiment because without it the team
could not be sure if caffeine produced the result. Since the study concluded that caffeine improved
people's ability to recall long–term memory, caffeine is beneficial for mental health. Although
caffeine has been proven to improve mental health, it can also harm it. Negative effects on a person's

Effects Of Caffeine On The Consumption Of Caffeine
Caffeine, a popularly consumed central nervous system stimulant is consumed on a day to day basis
around the globe. Caffeine can be ingested into the body by either eating it or drinking it. Caffeine
comes in forms of many processed foods such as coffee, chocolate bars, candy, sodas, and energy
drinks as well as tea. For example millions of people all around the world consume coffee on a daily
basis. Due to the large consumption of caffeine, both the negative and positive side effects of
consuming it have been well researched and documented. However the long term effects are much
more significant, the short term side effects of caffeine may not appear to be as extreme. The
regulation of caffeine consumption is crucial in order to guarantee that one does not become
dependent on it, and to ensure that an individual's body will not be damaged by doing so. The
evidence that backed up the claim that coffee is best consumed in small amounts and not on a daily
basis is overwhelming and clearly shows that coffee consumption must be carefully regulated and
controlled.
Caffeine is absorbed rapidly into the bodies blood stream. The blood stream carries the caffeine to
the bodies organs within minutes of caffeine consumption. The suggested safe amount of caffeine
for a healthy adult is around three hundred milligrams per day. The standard dosage of caffeine in
