The Effects of Creatine
Creatine has been used in sports throughout time. Athletes have always had a fascination with being excellent at what they do. With the banning of steroids from competitive sports and the implementation of random drug testing in most sports, most athletes are still somehow hoping to gain an edge on their competition. This edge that they are using is creatine.
In order to understand how creatine works, we must discover what creatine is. Creatine is an energy producing nutrient found in our bodies. It is synthesized from three amino acids arginine, glycine and methionine. These amino acids are primarily found in the liver, pancreas, and kidneys. It is also consumed in our everyday diets from fish, meat and other animal products. Creatine is not considered an essential nutrient in our diets.
In general, we consume approximately one gram of creatine per day in our diets (www.healthlink.mcw.edu).
Creatine helps provide the energy our muscles need to move, especially movements that are quick and explosive. Approximately ninety five percent of the body’s creatine supply is found in the skeletal muscles (www.pacific-nutrition.com). The other five percent is spread throughout the body, but mainly found in the heart, brain and testes. Creatine is easily absorbed from the intestinal tract into the blood stream.
Creatine was first discovered in 1832 by a French scientist, Cevreul. In 1847, it was noticed that the meat from foxes killed in the wild had ten times more creatine than meat from inactive foxes. The conclusion from this was that creatine accumulates in muscles due to physical activity. It was discovered in the early twentieth century that not all creatine consumed was excreted in the urine, but in fact, stored in the body. In 1912, researchers found that ingesting creatine can dramatically boost the creatine content of muscle. Fiske and Subbarow discovered creatine phosphate in 1927, and determined that creatine is a key player in the metabolism of skeletal muscle. Most studies focusing on creatine and sports performance have only been done since the early 1990’s (www.pacific-nutrition.com).

...rity. It claims to increase muscle strength and to delay fatigue, allowing athletes to train harder and longer. Companies promoting creatine supplements also claim that creatine can help burn fat and increase muscle mass. Annual sales of creatine in the United States alone are well over $100 million (Performance Enhancing Substances). Although creatine use in athletes is expected to increase because it is not on the list of banned substances as of yet, it is possibly going to be banned from professional sports, as well as NCAA sports, as early as next year.
I feel like creatine is great and should not be banned. How are athletes going to gain a competitive edge without a supplement that will allow their muscles to train harder? I have used creatine and I am still currently using creatine. I have seen the gains in muscle mass already only after two weeks of taking creatine. Drinking plenty of water is the key. As long as you take creatine as suggested, there should be no problems. There are no known serious side effects, therefore, I don’t think that creatine should be banned. Creatine is a great supplement for athletes to gain that competitive edge!
Creatine is one of the most popular sports supplements on the market and is used by bodybuilders, and athletes. It is an amino acid, like the building blocks that makes up proteins. It is also an important store of energy in muscle cells. Creatine is a natural nutrient found in our bodies and in the bodies of most animals. It can also be found in the form of a powder and sold as a supplement. Creatine is categorized as a food supplement by the Food and Drug Administration, like a vitamin and is available over the counter at drug stores and nutrition centers. Approximately 95% of the body’s creatine supply is found in the skeletal muscles. The remaining 5% of creatine is scattered throughout the rest of the body, with the highest concentration in the heart, brain, and testes. The human body gets most of the creatine it needs from food or dietary supplements.
Creatine serves as an energy reserve in muscle cells. Muscular contraction is powered by the breakdown of ATP (adenosine triphosphate) to ADP (adenosinediphosphate). When all the ATP is broken down, creatine phosphate in the muscle donates a phosphate group to ADP, and further energy reactions can occur. Creatine monohydrate is a precursor to creatine phosphate. By supplementing with CM, CP levels in muscle apparently are maximized, and more muscular work can occur, since there are greater energy reserves to use.
Creatine increases the body's ability to do work. It is high powered and generates the muscles ultimate energy source - ATP (adenosine triphosphate)- ATP produces the contractions of a muscle's proteins. When muscles are performing work ATP is being broken down into ADP (adenosine diphosphate) and energy is given off. The ATP being used usually lasts 10 - 15 seconds. After that the muscle depends on creatine phosphate to restock the ATP. Creatine acts as a reserve for the ATP. Therefore increased amounts of creatine will allow the body to supply ATP at a faster rate. Which, in turn allows an individual to workout longer and maintain a high level of strength. With creatine as a supple)-nent the body is exposed 4 grams of creatine per kilogram. Red meats give 1 gram of creatine per large serving.
A common goal for many works of literature is to achieve “thoughtful laughter,” in which the first response to a situation is laughter, but it makes the reader later think about its meaning and application in real life. One such work is The Adventures of Huckleberry Finn by Mark Twain, a brilliant work of American literature that is noted for its commentary on Southern Antebellum society. Twain’s humor in Huckleberry Finn is satirical in order to convey his thoughts on how cruel, self-absorbed, and hypocritical people in Southern society were. Tom Sawyer, the privileged and imaginative friend of Huck Finn, serves as a primary example of Twain’s “thoughtful laughter.” Tom’s mischievous yet subtly cruel personality and frequent escapades allow
“The Godfather of Soul”, better known as James Brown grew to be one of the most influential artists in Michael Jackson’s life. As a child Michael Jackson was intrigued by Brown’s flamboyant performances on stage and would soon begin to implement them into his own stage acts. By the age of five Michael Jackson was already sealed into a world of show business by his father, Joseph Jackson. Deprived of a childhood at a very young age, Michael and his siblings began a family-musical group called “The Jackson 5.” They began playing the soul hits they listened to on the radio all across the country. The band toured the Midwest extensively from 1966 to 1968, frequently performing at clubs and bars. In 1966, they won a major local talent show with renditions of Motown hits and a cover of “I Feel Good (I Got You)” by James Brown. It wasn’t until July 23, 1968 where they received major recognition by Motown owner, Berry Gordy. Gordy was reluctant to sign the “Jackson 5” but after their audition performance of the song “I Got the Feelin”, by James Brown, he changed his mind. In March 1969, “The Jackson 5”, were officially signed into Motown records. This marked a historical point in Michael Jackson’s life where his musical influences from James Brown would be noticed. Song’s from Michael Jackson that s...
Background on Creatine What is Creatine When I think of Creatine I don’t think of a body building supplement I think of an aid to recuperation. Like an aspirin you take if you have a headache, an athlete takes Creatine if they have chronic sore muscles from continuously working out. Creatine is a compound that can be made in our body. It is taken as a strength supplement. The chemical name for Creatine is methyl guanidine-acetic acid. The organ that produces the bodies Creatine is the liver. The amount of natural Creatine in the body can be increased or decreased depending on our diet(Absolute). How much Creatine do we have in our body? A 160-pound person would have approximately 120 grams of Creatine stored in their body (The Beg…). The reason Creatine is such a hot commodity is because 95-98% of the Creatine in our body is stored in our muscles.
Primarily lifters and athletes take creatine to get ahead of the competition. In an article written by Nancy Ling, she mentions how in the Olympic games from 1964-1994 Soviet Union powerlifters consumed creatine to get an edge on the competition and had great success from it. ("Creatine? Is It Worth the Risk?"). Also in the article, Nancy stressed the importance of taking the correct amount of creatine because it can help prevent kidney and liver problems. On the other side, consuming creatine can be dangerous if you are prone to having seizures, blood clots, or cardiac
Under President Franklin D. Roosevelt’s administration the atomic bomb was being developed. After Roosevelt died, his vice president Harry Truman was appointed President of the United States. Truman was never informed about the bombs development until an emergency cabinet meeting (Kuznick 9). Truman had to make the fatal decision on whether the bomb was to be dropped on Japan. With the idea of going to war, Truman had to think about the lives of the thousand American soldiers. The American soldiers had begun using the method of island hopping, because the bomb was not available. The idea of dropping a bomb was that the war itself could possibly end in its earliest points. The dropping of the atomic bomb could also justify the money spent on the Manhattan Project (Donohue 1). With a quote by Franklin D. Roosevelt “This will be a day that will live in infamy”, Pearl Harbor was a tragic day for Americans. The United States had lost many soldiers, which they had claimed that they will eventually get revenge. The alternates of dropping the bomb was also discussed at the Interim Committee. The American government was trying to get an invitation response from the Japanese government. If the United States did not drop the bomb and ‘Operation Downfall’ ha...
Creatine is produced by the body and stored in all kinds of muscles such as the heart, diaphragm, and all visible muscles. Creatine’s role is to
this is because creatine is most effective when the muscles are used for a short 6 seconds, then a long 45 second rest. The time period of using muscles for 6 seconds and then resting for 45 seconds is closely related to a football game where the players run a play, then get to rest until the next play is called. At the professional level of football, most teams are allowed to take creatine, but some teams are have banned the use of it because no one know the long term effects yet (Actions and Effects).
Abstract: Since the beginning of sports competition, athletes have always looked for some kind of an edge over their competitors. They will do whatever it takes to be one of the elite and that includes injecting supplements into their bodies to make them bigger, stronger, and faster. Steroid use is probably one of the most common drug misuses in sports competition. Athletes found that with anabolic steroids one could become a better athlete twice as fast. Not until 1975 was the drug first banned from Olympic competition because of the health risks it produced. Shortly thereafter, the rest of the sports world did not allow anabolic steroids as well. With the use of steroids no longer permitted athletes began to look for other alternatives. On the rise is two substances called creatine and androstenedione, both of which are sold over the counter. These two performance enhancers have only had minimal testing done on them, excluding the long-term effects, simply because they haven't been around long enough. Creatine and androstenedione have been said to produce results like steroids without the side effects. The truth is they do produce side effects and irregular muscle growth. By banning the use of performance enhancing drugs, just like steroids, sports competition will have a much healthier and fairer environment to participate in.
Although the film and the novel of Abraham Lincoln: Vampire Hunter highlighted different characters and other versions of Lincoln, they shared a commonality in the underlying themes discussed within the works that later helped to explain the alteration of his character as a result of the Twenty-First Century. One of the main themes shared between the works was the fight against oppression and injustice. An immediate connection was made between vampires and slavery: the reason for the imprisonment of the African American race in the South was due to vampires. The movie said that “killing a slave was not considered murder, no matter the circumstances” and went on to illustrate how this fact upset President Lincoln to the point where he wanted
An icon for decades, legend for an eternity, Michael Jackson 's impact on the world continues to thrive as a silhouette amongst pop culture. His music has influenced many people to "Xscape" from the deceptions of all the "Dirty Diana[s]." Yet, his talent has encouraged people to "Scream" through all the "Thriller[s]" they receive as his stardom illuminates the stage as the "Smooth Criminal" of performances. His songs vary from selections that you can "Jam" to, those that promote tough love and adornment, while some are advocates for equality. Jackson is and will remain one of the most profound superstars of his time and one of most dynamic artist in "HIStory."
Introduction: Perhaps no one has received this title in history “the king of pop”, now a days many artist’s have arisen and have performed but not as the king of pop known worldwide and in history, has dominated the world of pop as Michael Jackson.
Much to athletes' delight, a new promising product, creatine, has recently appeared on the market. Creatine is a substance found in meats and synthesized by the human body but the latest craze is over artificially made creatine. Many athletes take it in hopes of increasing their strength, speed, or endurance. Althoug h the initial results of creatine testing were very positive, showing potential to help athletes increase their strength and speed, new evidence shows that creatine is not as perfect of a nutritional supplement as it once appeared to be. Creatine supplementation is now being linked to several hazardous side effects in the body and even its effectiveness has come into question. The use of creatine supplements by athletes is a dangerous wa y to enhance performance and should be regulated or banned.
