Caffeine and Sports Performance
Caffeine is a mild stimulant that occurs naturally in at least 63 plant species. Caffeine can be found in the leaves, stems, seeds, and roots of these various plants. Caffeine is part of the methylxanthine family. It consists of a xanthine molecule with three methyl groups attached to it. Caffeine can be found in many products like sodas, tea, and coffee, but it also occurs in several other products such as prescription medications, diuretics, and pain relievers. Caffeine’s widespread use and popularity have caused many people to view the substance as an addictive drug. Thus making caffeine the most inexpensive and readily available drug known to man. Then on the other hand there are people who view caffeine as a helpful stimulant that increases the individual’s concentration and awareness as well as many other physical traits. The important thing to remember is that caffeine’s affects vary based on the person, the amount ingested, the frequency of consumption, and individual metabolism.

Purpose of Caffeine in Athletics
Caffeine has many specific benefits for different types of athletes. Though much of the research on caffeine in athletics is inconclusive, there are many athletes that believe the substance can enhance their physical as well as mental performance. It is supposed that caffeine can improve the athlete’s endurance in sports where long-term stamina is needed. These sports include cycling, running, and even soccer. In an experiment to study the effects of caffeine as an ergogenic aid, 6 regular caffeine users were monitored while they exercised until exhaustion. During this double ...

This book focuses on different types of calendars from a number of different places all around the world. This specific chapter, even more specifically this section, focuses on the Mayan calendar. These calendars were written by honored members of their aristocracy and were held to be of great value. The Spanish invaders believed them to be instruments of the devil and burnt great quantities of them. E. G. Richards explains that only four Mayan books are survive in the libraries of Europe, and one of those—The Dresden codex—suffered severe damage in another fire, one which was inflicted on that city in the Second World War. Richards says that the earliest record of a calendar survives from about 500 BC in Monte Alban near Oaxaca. This calendar employs a 260-day cycle, which was commonly used by several societies and is still in use among the present-day inhabitants of the region. The Maya used the calendar partly to anticipate propitious days to embark on wars and other activities. It was also used to record on stone pillars, or stelae, important events in the lives of their kings and to relate these to more mythical events of the past. The Mayan calendar system involved two major methods of specifying a specific date—the calendar round and the long count. The calendar round was used to specify a date within a period of about 52 years, while the long count served to relate such dates within a longer period named a great cycle. The calendar round involved three interlocking cycles of 13, 20, and 365 days respectively. The 365-day cycle was called a haab and was similar to the Egyptian wandering year. Each haab was divided into 18 periods called uinals; each uinal had 20 days and a name. The 18 uinal were followed by five epagomen...
One of the major kidney problems that we face every day is Acute Renal Failure also called the Acute Kidney Injury which basically is that kidneys have suddenly stopped working and as I said earlier, our kidneys excrete waste products and balances fluids in our blood, so imagine not having a perfectly working kidney, it could cause serious problems in our body that could also be fatal.
The prediction for this experiment is that the higher the concentration of the caffeine, the higher the heart rate in beats per minute. This is because caffeine acts as a stimulant, causing the adrenaline hormone b...
1 in 3 Americans Adults are currently at risk for developing kidney disease. What is acute renal failure, when your kidneys functions all of a sudden stop working and your kidneys are the body’s filter which remove waste products and help balance water, salts and minerals especially electrolytes in your blood when your kidneys stop working you end up building all the products in your body that need to be filtered and eliminated. The pathophysiology of Acute Renal Failure are due to three main causes Pre-renal, Intra-renal, and Post renal. Pre-renal is a sudden drop in blood pressure or interruption of blood flow to the kidneys from illness or sever injury. Intra-renal is direct damage to the kidneys by inflammation of drugs, infection, toxins or reduced blood supply. Post-renal is a sudden obstruction of urine flow because of enlarged prostate bladder tumor, kidney stones, or injury.
"Drunk with melody, and what the words were, he cared not." This was a very common view among early commentators about Dylan Thomas (Cox 1). Thomas was a poet who was either loved or hated. It depended on the individual, and how they viewed his poetry. He was very famous for his poetry because it contained visions of life, aspects of birth and death, fear, grief, joy, and beauty. At a younger age, Thomas was a very violent poet. As he grew older, he spoke for all men greatly when he wrote. He wrote his poems referring to the qualities and sensations of life. The strength of feelings, which were expressed in his writings, gave many different impressions about Thomas’ attitudes toward religion and spirituality, relationships, and the passion in his poetry.

The basic function of a working kidney is to remove toxic waste from the bloodstream, balances body fluids and forms urine. (WebMd, 2013) When the kidney, which is an essential part of the human body fails and blood flow is compromised by electrolyte and acid base abnormalities this is Acute Renal Failure (ARF) also known as Acute Kidney Injury. There are three major causes of acute renal failure. First being Prerenal, which is primarily a severe drop in blood pressure and cessation of blood flowing to the kidneys caused by a traumatic injury or a severe illness. Secondly, another cause is Intrarenal which is the Middle stage of renal Failure, manifested by edema, toxins, drugs and decreased blood supply. Lastly, Postrenal is when the urine flow is compromised due to an enlarged prostate, stones, and/or a bladder tumor. According to the American Family Physician (2000) 60 to 70 percent of cases are prerenal causes.
The renal disease are common nowadays .The acute renal failure is a medical term means that the kidneys stopped from working and not able to clear toxins from body ,not able to maintained a stable electrolyte balance inside the body and not able to secret the extra fluid as urine outside the body. The renal replacement therapy (RRT) or dialysis has been discovered on 1913 by Able, Rowntree and Turner in London, UK.
...ease of calcium, and reduction of lactic acid is a result of glycogen sparing. In endurance exercise, caffeine allows athletes to exercise for a longer duration through glycogen- sparing, burning fats as fuel, increase calcium production, and increase in alertness and adrenaline. Caffeine is also proven to improve reaction time by the increase amount of adrenaline the caffeine provides. Caffeine also aids in post-work out pain an athlete may experience after a rigorous workout. Caffeine also has its health benefits. Caffeine reduces the risk of: liver cancer by improving enzyme activity, Alzheimer’s by blocking the progression of the disease as a result of the A2A antagonist, and Parkinson’s disease by protecting dopamine- producing cells. Ultimately, caffeine is shown to have a positive effect on an athlete’s performance, and also has positive health benefits.
During tasks that involve memory, and other cognitive processes the research will try to confirm the belief that caffeine is a cognitive enhancer. Whether students are in a withdrawn state, a normal caffeinated state, or just moderately use caffeine it has an effect on their memory, attention, planning, capacity, and psychomotor performance. Along with the effects of caffeine, student’s performance can be influence by other factors such as mood, the time of day, personality, intelligence, age, memory span, education, gender, socioeconomic status, occupation, smoking, expectancy, and/or alcoh...
If the patient has a urinary catheter, and most ICU patients do, he or she may not have any reportable symptoms. Therefore, good assessment of urinary elimination, done in relation to a patient’s signs, symptoms, urine amount, intake and output, and lab values, is important. The lab values are discussed in Chapter 5. Acute and chronic renal failure can cause numerous systemic symptoms and altered homeostasis ( Collins, 2011). See Table 3-10 for abnormal urinary elimination.
What happen to the caffeine when it is ingested, and what are its consequences? In addressing these questions, there have been many contributors spent much time to prove that caffeine has been shown to behave as an adenosine antagonist to stimulate motor activity, mood and behavior. This antagonist behavior is the basis for an increase in cholinergic and dopaminergic behavior after caffeine intake. Beside of that, the acute administration of caffeine has been reported by several laboratories to elevate brain level of serotonin (5-HT) and 5-hydroxyindoleacetic acid (5-HIAA). This increase of serotonin may be associated with the improvement in good mood. Recent studies also show the higher caffeine intake to a lower suicide risk. In this paper, I will investigate the caffeine at a biochemical level and relate its effects on physiological behavior of human with information from the recent research.

Caffeine is a chemical found in coffee, tea, soft drinks and various easy to get foods and drinks. Like all drugs, caffeine has its good and bad side. Caffeine’s categorized as a stimulant, meaning it temporarily increases alertness and energy. With this stated, you may ask yourself, what’s so bad about a little high associated with coffee or chocolate? I mean it’s practically harmless, right.
Coffee is the first thing that people associate with instant energy on a groggy morning. “In the U.S., coffee is king of beverages” (Reinke) Research has been done that has named coffee as an addiction to the people who consume large quantities of it. Coffee was named the top source of antioxidants. This is partly because of the amount consumed each day. Some of the antioxidants that coffee has are quinines and chlorogenic acid. It also contains trigonelline, an antibacterial compound. This is where coffee acquires its delicious aroma. Now let’s step back for a minute and just think about how much caffeine people consume. In an 8oz cup of coffee it has about 85 milligrams of caffeine. This is about double the amount that tea contains. Studies have shown that caffeine stimulates the brain and nervous system. This is where you get that energized feeling. After about the third cup, knees start to bounce, pens are clicking and people start running laps around the office. Caffeine can become addicting if you drink too much. Coffee can become that addictive habit people are unable to shake.
