Essay On Caffeine

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).

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.

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 is a natural product that is extracted from the raw fruit of coffee plants over sixty creased alertness. Caffeine gives most people a temporary energy boost and elevates mood..species to be exact. kola nuts, cocoa, yerba maté, guarana berries, coffee beans and teas contain this. Caffeine is rapidly absorbed in about 30 to 60 minutes in our bodies after ingestion. Caffeine is defined as a drug because it stimulates the central nervous system, causing increased alertness. Caffeine gives most people a temporary energy boost and elevates mood.caffeine can also be in things like over the counter medications, and pain relievers.

Caffeine is a very popular stimulant among athletes because most believe that it provides energy, increases alertness, and quickens reaction time. When in beverage form,

A single-blind experiment was used to study the effects of respiratory and cardiovascular to different exercise levels under the impact of either a placebo or atenolol, with a total group size of 97 volunteers involved. The drug assignment of either a placebo or atenolol to the volunteers is completely randomized to avoid bias and reduce any mental influences during exercise. However, class separation into groups is mainly not randomized and with freedom to choose. Moreover, each volunteer must have had a consent form signed prior to drug administration, ensuring ethical approval. There are additional factors that are provided such as height, weight and sex. Furthermore, the measurements taken may be inconsistent and inaccurate as there

Subjects were given their treatment of either beetroot juice or placebo ninety minutes prior to commencing the examination. Then, they began the treadmill portion of the exam, where VO2, VCO2 and RER data was collected at each varying intensity of the test. After completion of the treadmill test, subjects were then taken to an indoor track to complete the 1500m TT. This began 2.5 hours post-supplementation. After completion of the TT, subjects were then briefly quizzed to confirm the anonymity of the treatment they received. There were four experimental trials performed, with blood sampling occurring at the conclusion of each for plasma NO3 analysis. Throughout the course of the experiment, dietary standards were set in order to reduce confounding variables that would potentially alter the accuracy of the experimental procedure. Additionally, the supplementation blinding used by the experimenters was very successful, as subjects were only able to correctly identify the treatment they received 50% of the

The most precise method for the assessment of maximal oxygen consumption is the direct measurement which is considered the ‘gold standard’ (Noonan & Dean, 2000). However, the use of this method is limited in several settings such as in sports clubs, schools, or in large scale research studies (Pescatello & American College of Sports Medicine, 2014) because it requires appropriate and expensive equipment, supervision by trained personnel and a max-imal level of exertion which cannot be achieved by all the individuals and especially those who may be limited by pain, fatigue, abnormal gait, impaired balance or those with cardio-vascular problems(Evans, Ferrar, Smith, et al., 2015). As a consequence, many indirect tests have been developed for use in sports, clinical and home settings but there are sundry fac-tors which must be considered when we select one of them. Such factors are the population that we

How does caffeine work in the body to create such effects? Caffeine is absorbed quickly from the GI tract, and is significantly elevated in the blood in 15 minutes, with peak concentration at 60 minutes. It passes through the blood-brain barrier and affects brain centers leading to an increase in alertness and decrease in fatigue and drowsiness. It stimulates the nervous system, affects respiration, boosts energy levels and thereby is beneficial at enhancing sports performance. Caffeine helps to mobilize fat stores so the body can use it as a primary fuel source, thus sparing glycogen. The delay in depletion of muscle glycogen

Many of us find ourselves drinking a freshly brewed cup of coffee, an ice cold soft drink, a hot cup of tea, or an energy drink whether it be in the morning, afternoon, or in the night but one thing is that they all share a common ingredient: Caffeine

The metabolism results of study A showed caffeine results (Fig. A) as expected. Pre-caf gave the earliest caffeine reading, followed by dur-caf. Urinary caffeine levels (Fig. B) were well below the International Olympic Committee regulation of 12µg/ml. Plasma analysis showed that blood glucose levels were higher in the pre-caf treatment, possibly due an increase in metabolic rate from the

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
