Performance Enhancing Drugs: Doping in Sport PE
Head coaches are often the highest paid person on the payroll at unis. Those same unis educate the nation and world, and they teach people to implicitly accept, support, and habituate negligence, inadequate testing, white collar crime, and abuses associated with sports doping. The rest are somewhere in the domino line in the USA. Steroids only have a negative effect given misuse and abuse. The suggestion that steroid hormones should not be used in medicine is flatly absurd. Taking these drugs could be considered cheating as well. While there are many players in sports taking Performance Enhancing Drugs, there are still many who do not. For the ones who do not use them, they put in hours of hard work to get stronger for the sport they play.
Athletes that do take them get the same effect in a much shorter time frame and many of the drugs they take give them more energy to work out harder and longer. They also do not show the true skills that a player may possess. For example, if a baseball player is a weak hitter but then takes steroids and works out while he is on them, he will get really big and strong and start to crush the baseball, then he is showing the skills that the drugs helped him create.
A Tuft University study showed that steroids can increase home run production by 50 percent showing that steroids are the reason why this weak hitter started crushing the baseball. Steroids help people get stronger a lot faster than if they did not take them. The focus of league officials would come back to the sport being played. Instead of them worrying about who has been taking Performance Enhancing drugs and how long they need to suspend that person for, they could worry about who hit a walk-off home run in the bottom of the 9th or who just won the gold in the Olympics all without worrying about what they did to get so good. Performance enhancing drugs should not be allowed in any sport ever and the government should stay out of the entire struggle with these drugs in sports.
The problems with Performance Enhancing drugs has proliferated over the years but if the government stepped in and tried to deal with it, it would just give them another responsibility that they may not be able to handle. They may also be able to take steps that are too extreme, such as throwing people in jail. Performance enhancing drugs are profoundly harmful deleterious to the human body and should under no circumstances, be used in sports.
They cause many life threatening illnesses such as heart attacks and disease. Keep all Performance Enhancing drugs out of sports forever! Steroids should be banned because in professional Chris Benoit murdered his wife, his son and then himself; the cause was from steroids. Eddie Guerrero was another professional wrestler who died from heart failure in from steroid use. Benoit and Guerrero were young. Marc Velasquez Chris Benoit did use steroids but what they say drove him to kill his wife and child was tramatic brain injury from taking bumps to the head over and over again. They said his brain was that of a year-old dementia patient. Eddy did steroids too but his heart problems were caused by years of hard drugs and prescription drug use not steroids.
Steroids need to be illegal!! It is not fair for people who work hard for their big muscles and who go to the gym everyday, and someone else just injects themself with a needle or whatever. And it is so horrible for the people who take steroids because it messes up your body so much!!! Steroids are just an excuse or an easy way to get bigger. People who uses steroids are just lazy to work for it or gain it themselves. Steroids should be allowed in professional sports, because after all, playing a professional sport is a job. Why should someone be denied from something that will help them be better then their competitor. With concussions becoming such a big deal recently you would think people would want to stop athletes from getting even stronger and possibly giving more concussions to other players.
Musberger should be ashamed of himself. Getting to the top of the mountain should be earned through discipline, hard work and perseverance — not by cheating or using a quick fix. I disagree with you because, doping does affect the integrity of the sport along with the health of the athlete. Getting a joint reaper is a surgery to get a athlete back in to the sport. Tom Kamenick. I agree and feel that steroids should be banned.
The reasons why are pretty clear including the obvious health concerns, unfair advantages it provides and also the message it sends to our younger generations. When you think of basketball household names would be Michael Jordan, Dr. Now think about how devastated they would be and what it would do to the sport itself. It puts in jeopardy the very programs that are meant to get those athletes face time with younger generations. To plant those lifetime roots of and keep those kids on the straight and narrow with at young ages a very achievable goal of becoming a professional. Majority of kids at some time have definitely sat in the backyard and done countdown of 5,4,3,2,1 score and the crowd goes wild.
Testosterone is partially responsible for the developmental changes that occur during puberty and adolescence and is also involved in controlling the build-up and breakdown of the main biochemical components of all tissues, including muscle. Exogenous steroids are synthetically created versions of the testosterone hormone. These substances cannot be naturally produced by the body. Endogenous steroids are naturally occurring substances in the human body that are involved with the metabolic pathways of testosterone. Because testosterone affects muscle growth, raising its levels in the blood can help athletes increase muscle size and strength. Anabolic steroids can be taken in tablet form or injected directly in to the muscle.
Some of the most common types of anabolic steroids include:. Athletes who use anabolic steroids claim that as well as increasing muscle mass, they reduce body fat and recovery time after injury. But the androgenic masculinising side-effects—such as increased body hair and a deepening of the voice—are not always desirable, particularly in women. To counteract these side-effects, scientists developed steroids that retain their anabolic effects but have a lower androgenic effect. Androstenedione was used by East German Olympic swimmers and other athletes in the s and s to improve their performances.
Medical experts see significant dangers in the use—and particularly the gross over-use—of anabolic steroids. Some of the effects are minor or only last while the drug is being taken; others are more serious and long-term. For example, anabolic steroids can cause high blood pressure, acne, abnormalities in liver function, alterations in the menstrual cycle in women, decline in sperm production and impotence in men, kidney failure and heart disease. They can also make both men and women more aggressive. Testing for anabolic steroids has come a long way since the s, when basic radioimmunoassay GLOSSARY radioimmunoassay RIA is a sensitive method for measuring very small amounts of a substance in the blood.
Radioactive versions of a substance, or isotopes of the substance, are mixed with antibodies and inserted in a sample of the patient's blood. The same non-radioactive substance in the blood takes the place of the isotope in the antibodies, thus leaving the radioactive substance free. The amount of free isotope is then measured to see how much of the original substance was in the blood. Today, anabolic steroids and their by-products can generally be detected quite easily in urine, using mass spectrometry.
Testosterone and a related compound, epitestosterone, are eliminated from the body in urine. There are problems with this test. Today, anti-doping labs use the combined technique of Gas Chromatography GLOSSARY Chromatography a technique for the separation of a mixture by passing it in solution or suspension through a medium in which the components move at different rates. This is an analytical method that combines the features of gas-phase chromatography and mass spectrometry to identify different substances within a test sample, effectively detecting differences in the ratio of carbon isotopes in different compounds.
This technology can distinguish between testosterone produced naturally by the body endogenous and that which is a result of synthetic compounds exogenous. Continuing advancements in the detection of steroids and stimulants are currently being developed. In the U. S, a research team is working on a detection system that is being touted as a fold improvement on the commonly used mass spectronomy technique. The new technique, named Paired Ion Electrospray Ionisation PIESI makes traces of steroids or amphetamines more visible to current detection equipment by introducing a chemical agent which effectively binds itself to the traces, right down to the parts per trillion.
To develop reliable tests, researchers have to know what they are looking for. This is difficult because the development of new 'designer' steroids is an on-going process. The World Anti-Doping Agency is aware of the problem. In they were able to develop a test for one of these designer steroids—tetrahydrogestrinone THG —when a syringe full of the drug was given to them. Human growth hormone HGH; also called somatotrophin or somatotrophic hormone is a naturally-occurring hormone produced in the human body. It promotes physical development—particularly the growth of bone—during adolescence. It stimulates the synthesis of collagen, which is necessary for strengthening cartilage, bones, tendons and ligaments, and also stimulates the liver to produce growth factors.
In adults, HGH increases the number of red blood cells, boosts heart function and makes more energy available by stimulating the breakdown of fat. Other effects attributed to HGH include increase in muscle mass and strength as well as tissue-repairing recovery. Still, it is quite easy to see why athletes believe it will enhance their performance. English Rugby player Terry Newton was suspended in after testing positive for human growth hormone, while Bulgarian sprinter Inna Eftimova was banned from competition in after a returning a positive HGH test. If you believe all the hype—emanating mainly from drug manufacturers—HGH is a wonder drug that will remove wrinkles, reverse the ageing process, restore vitality and improve sleep.
Nevertheless, there are some health risks. For example, too much HGH before or during puberty can lead to gigantism, which is excessive growth in height and other physical attributes. After puberty, inflated levels of HGH can cause acromegaly, a disease characterised by excessive growth of the head, feet and hands. The lips, nose, tongue, jaw and forehead increase in size and the fingers and toes widen and become spade-like. The organs and digestive system may also increase in size, which may eventually cause heart failure. Acromegaly sufferers often die before the age of Excessive use of HGH in adults may also lead to diabetes; muscle, joint and bone pain; osteoarthritis; cardiac limitations; hypertension; and abnormal heightened symptoms of cardiovascular disease.
A full description of the testing method is available on the WADA website. This dual-approach test has been confirmed as robust and scientifically reliable by the Court of Arbitration for Sport. Higher levels of red blood cells in the blood result in more oxygen being transported to the muscles, resulting in increased stamina and performance. There are three main types of blood doping:. Erythropoietin—more commonly known as EPO—has long been the drug of choice for endurance athletes.
Although used in a wide variety of sports, it is most commonly associated with cycling—particularly with the disgraced former champion of the Tour de France—Lance Armstrong. Produced naturally by the kidneys, EPO is also available as a pharmaceutical. EPO stimulates the production of red blood cells in bone marrow and regulates the concentration of red blood cells and haemoglobin in the blood.
This is useful for athletes, since red blood cells shuttle oxygen to the cells, including muscle cells, enabling them to operate more effectively. Longer chains of amino acids are called proteins. By injecting EPO, athletes aim to increase their concentration of red blood cells and, consequently, their aerobic capacity. If EPO levels are too high the body will produce too many red blood cells which can thicken the blood, leading to clotting, heart attack and stroke. In fact, EPO has been implicated in the deaths of numerous athletes, predominantly cyclists. Repeated doses of EPO can also stimulate the development of antibodies directed against EPO, which can result in anaemia.
The long-term health risks of sustained EPO use are still unclear. The Tour de France hit controversy when the entire Festina team was disqualified after several hundred doses of EPO and other doping products were found in the team car. Methods such as isoelectric focusing, which is the separation of proteins based on their electrical charge, and sodium dodecyl sulfate polyacrylamide gel electrophoresis, which is the separation of proteins based on their size, are used to detect EPO. Since , EPO tests in the United States were undertaken using only urine, however, in recent years the joint testing methods, such as direct EPO testing in urine and use of indirect blood tests as part of the Athlete Biological Passport see below , have been used to help identify the use of newly-developed erythropoiesis stimulating agents.
A new testing technique for EPO is also in the pipeline. In essence the new test will look for genetic expressions which prove that EPO has been used. If the new test proves accurate and viable, it will be almost impossible to use EPO without detection. Synthetic oxygen carriers SOCs are purified proteins or chemicals that have that ability to carry oxygen. They are still under development and have not been approved for use outside of South Africa and Russia.
SOCs were developed for use in crisis situations where blood transfusions are not possible or blood products are not available. There are several different types of SOCs available. Like red blood cells, they work to deliver this oxygen to the muscles, increasing aerobic capacity and endurance. However, they also have some additional benefits. HBOCs are not only great at tissue oxygenation, they can deliver increases in blood serum iron, ferritin and naturally occurring EPO. SOCs are still under development and testing, and have not yet been proven safe for human use. Athletes and coaches are encouraged to bend the rules wherever possible in order to gain a competitive advantage over an opponent, and to pay less attention to the safety and welfare of the competition.
Some of the key tenants of gamesmanship are:. All of these examples place greater emphasis on the outcome of the game than on the manner in which it is played. A more ethical approach to athletics is sportsmanship. Under a sportsmanship model, healthy competition is seen as a means of cultivating personal honor, virtue, and character. It contributes to a community of respect and trust between competitors and in society. The goal in sportsmanship is not simply to win, but to pursue victory with honor by giving one's best effort. The sportsmanship model is built on the idea that sport both demonstrates and encourages character development, which then influences the moral character of the broader community. How we each compete in sports can have an effect on our personal moral and ethical behavior outside of the competition.
Some argue for a "bracketed morality" within sports. This approach holds that sport and competition are set apart from real life, and occupy a realm where ethics and moral codes do not apply. Instead, some argue, sports serves as an outlet for our primal aggression and a selfish need for recognition and respect gained through the conquering of an opponent. In this view, aggression and victory are the only virtues. For example, a football player may be described as mean and nasty on the field, but kind and gentle in everyday life. His violent disposition on the field is not wrong because when he is playing the game he is part of an amoral reality that is dictated only by the principle of winning.Caffeine reduces low-frequency delta activity in the human sleep EEG.
