Caffeine In Sports

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.

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.

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

Another study looked at the effects of acute caffeine ingestion on sprint performance following a week of creatine loading (7). Creatine loading is simply ingesting 20-30g of the creatine supplement daily for a week (5-7days). In the study the mean and peak power of the caffeine and creatine treatment group were significantly higher than the control group (7). With increased peak power more force production is being produced, thus sprinters are more explosive, enhancing their sprint performance. By increasing the mean power, the sprinter is able to maintain their performance for a greater

Symptoms that follow caffeine consumption are: anxiety, panic attacks, increased heart palpitations, trembling, stress, heartburn, and the deprivation of sleep (Driedger, Doyle par 2). Over time these symptoms can become more severe and eventually will become a major disturbance in one’s life. The anxiety that comes from this can be especially harmful to those who suffer from anxiety disorders, such as GAD-General Anxiety Disorder and Panic Disorder as the caffeine can stimulate a panic attack (Human par 3). The most apparent concern of caffeine consumption, is its effects on teen life. Dr. Jim Lane, a researcher at Duke University stated, “Teens are chronically sleep deprived. Caffeine use might be a consequence of that, and also a cause. Drinking coffee could lead to sleep-onset insomnia, or a delay in going to bed, that contributes to sleep deprivation” (Teens par 7). This shows that as the caffeine trend among teens continue, the link to teen sleep deprivation strengthens. Not only does it prevent the continuation of sleep, but also the process of even falling asleep is delayed. The more deprived of sleep these

Shukitt, Speckman, & Tulley, 2002). Hodgson et al.’s (2013) participants consisted of eight qualifying cyclists who trained three times per week, for more than 90 minutes. A preliminary trial was assessed before the experiment started. In that trial, the cyclist’s maximal oxygen uptake and power was assessed. Following this, each cyclist drank beverages containing caffeine, placebo, coffee, and decaffeinated coffee, each on different days. One hour after consumption, they completed a 30-minute steady state cycle exercise followed by a 45-minute energy based time trial exercise. Blood samples and respiratory breath samples, and heart rate were recorded during the exercise session. The main finding of this study was that a cup of caffeinated beverage helps improve endurance during exercise. Compared to placebo and decaffeinated drinks, there was a significant dopamine increase in the athlete’s brain. Therefore drinking coffee during workout can be beneficial as it enhances one’s performance. In Lieberman et al.’s (2002) study, moderate

The several research on articles have been done to study the effects of ingestion of caffeinated energy drink before, during or after exercise to determine its outcome on the performance of the athletes. All the articles showed a positive association between caffeinated energy drink and strength. The ingestion of caffeine 3-6mg per body weight proved to enhance the strength of players and improved their performance. The athletes should not intake more than 6mg per body weight as it can lead to various side effects and adversely affect the body and also consumption of caffeine less than 3mg per kilogram showed no effect on the body. Although, the caffeinated energy drink proved to enhance the strength but the mechanism of the strength improvement

The intent of caffeine and sleep deprivation is to help the students through pressure and stress of studying from courses that they are taking. However, in actuality, caffeine and sleep deprivation effectively enlarge the gap between proper sleep and restfulness needed for body to function efficiently. However, the effects of caffeine on elevated cognitive processes are well researched even though it is “useful for restoring basic alertness and vigilance” (Huck 489). Although, caffeine seems to provide an equal opportunity for students to excel in their studies regardless of the lack of sleep that they are receiving, there is evidence that suggests caffeine may have a distinct advantage over needed sleep. Furthermore, the paper will

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

One drug that used more than most for not only athletes but for those that need to feel a pick me up in the middle of the day. This drug is can be traced back thousands of years as a stimulant before they knew even what it was. Today, this drug is used in a variety of settings both for medical and recreational uses. However, this drug is taken by most people recreationally and don’t even know it. This can be a concern for those that have a sensitivity to this drug. The drug that almost most citizens throughout the world will have taken in their lifetime and not even realize it, is caffeine. For some this is an essential part of their everyday life or the feel a crashing effect come over them.

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.
