  • The Wrong Way to Win › Introduction to The Wrong Way to Win › Why Do Athletes Use Performance-enhancing Drugs? › Masking Pain and Managing Weight and Stress › Detecting Drugs Why Do Athletes Use Performance-enhancing Drugs?
  • An athlete may want to: Build mass and strength of muscles and/or bones Increase delivery of oxygen to exercising tissues Mask pain Stimulate the body Hide use of other drugs
  • Many drugs are banned outright in Olympic competitions. However, some drugs, such as cortisone and local anesthetics, are merely restricted because they have legitimate clinical uses. Athletes may also misuse drugs to reduce weight, relax, cope with stress or boost their own confidence. Whatever the reason, doping has many unsafe if not deadly side effects.

  • Athletes looking to build mass may also abuse Human Growth Hormone (hGH). Excessive hGH levels increase muscle mass by stimulating protein synthesis, strengthen bones by stimulating bone growth and reduce body fat by stimulating the breakdown of fat cells. Use of hGH has become increasingly popular because it is difficult to detect. Side effects include overgrowth of hands, feet, and face (known as acromegaly), enlarged internal organs, especially heart, kidneys, tongue and liver and heart problems.
  • In addition to taking drugs that build mass and strength, some athletes take drugs and engage in practices that increase the amount of oxygen in tissues. Endurance athletes, like cyclists or cross-country skiers, may use Erythropoietin (EPO). EPO can increase an athlete's oxygen supply by as much as seven to 10 percent. As mentioned earlier, EPO is extremely dangerous, if not deadly in some cases. The increased red cell density caused by EPO can thicken the blood. The thickened blood -- which is more like honey than water -- cannot flow through the blood vessels well. To pump the thickened blood, the heart must work harder. This increases the chances of heart attack and stroke.
  • Another method for improving oxygen concentration is blood doping -- infusing whole blood into an athlete. An athlete who infuses his own blood may cause infection or cardiovascular problems because of the increased blood volume (high blood pressure, blood clots, heart failure and stroke). An athlete who uses someone else's blood runs the risk of acquiring viral infections such as HIV/AIDS. These are huge risks for a result that can also be achieved by training at high altitudes.
  • Athletes use anabolic steroids to increase muscle strength. Anabolic steroids, which can be injected or taken as pills, allow the athlete to train harder and longer at any given period. The possible and well-known side effects of anabolic steroid use include jaundice and liver damage, mood swings, depression and aggression. Men may also suffer from baldness, infertility and breast development. Females may grow excessive hair on the face and body and suffer from infertility. The substances Human Chorionic Gonadotropin (hCG), Luteinizing Hormone (LH) may also produce the same side effects.

The dope on steroids: Why some athletes take the risk : UMNews : University of Minnesota - 0 views

www1.umn.edu/...me_athletes_take_the_risk.html

shared by anonymous on 03 Dec 08 - Cached
  • The stakes in Athens are fierce. The difference between an Olympic gold or silver medal could be a one hundredth of a second on the track or in the pool; an inch on the pole vault or shot put.
  • The athletes who make the Olympic cut are blessed with the right combination of physical and psychological traits, including an intense competitive drive and an unrelenting determination to be the best. This is the stuff of champions.
  • Steroids are not just for elite athletes--they can be used by anyone who wants to change his or her body image. The Centers for Disease Control's Youth Risk Behavior Surveillance report shows more than a million youth taking steroids, and the numbers have been rising every year.
  • ...13 more annotations...
  • Unfortunately, sometimes so are steroids. For decades, athletes have used anabolic (meaning muscle-building) steroids and other performance-enhancing drugs to build strength and endurance. And those drugs are getting more and more sophisticated in an effort to evade detection. Doping, as the practice is called, is illegal and, by most people's standards, unethical. Athletes who have been caught using these drugs have been stripped of their Olympic medals and world records and banned from their sports, sometimes for years, and on occasions for a lifetime.
  • "There are rights and wrongs in life, and if it's against the rules, it's cheating to do it," says Wiese-Bjornstal. "I love sports, but some athletes treat elite sports as if they are life itself, more important than their health, their loved ones, and even their lives."
  • In addition, steroids mess with your body. Potential side effects include high blood pressure, strokes, nausea, sleep problems, increased aggressiveness, and severe mood swings. In men, steroids can reduce sperm count and cause impotence, breast growth, and shrunken testicles. In women, side effects can include reduced breast size, increased body and facial hair, a deepened voice, and menstrual problems.
  • With the risks and consequences of steroid use so high, why do some athletes continue to dope?
  • "The major underlying factor [with steroids use] is that winning at all costs is the most important thing," says Diane Wiese-Bjornstal, associate professor in the School of Kinesiology.
  • She says that athletes that use steroids often have the mindset that "they are demonstrating that they are as highly committed to their sport as they can be and are doing whatever it takes to prove to themselves, their coaches, and to the world that they are true athletes who will do anything to win."

      Diane Wiese-Bjornstal's Comment
  • From a moral and ethical framework, Wiese-Bjornstal believes this is twisted thinking. "There are rights and wrongs in life, and if it's against the rules, it's cheating to do it," she says. "I love sports, but some athletes treat elite sports as if they are life itself, more important than their health, their loved ones, and even their lives."

      Wiese-Bjornstal's Comment
  • She also says there is pressure to dope because of the belief that everyone else is doing it, and that if an athlete wants to compete at the highest level, she or he has to do it, too.
  • Nancy Cullen, a sports psychology consultant for the University, says the temptation to use steroids and other performance-enhancing drugs simply comes down to the rigors and pressure of elite competition and the desire to win. She cites an alarming poll taken in 1995 of 198 sprinters, swimmers, power lifters and others, most of whom were Olympians or aspiring Olympians. The poll asked if the athletes would take a banned performance-enhancing substance if they knew if would help them win and they wouldn't be caught--195 responded, yes.
  • Most athletes train for perfection," says Cullen. "The drive to achieve and win is so strong. If the difference between winning or losing is a hundredth of a second, and there is a drug that might give you the edge, the temptation can be great."
  • For some Olympic events, steroid scandals have cast a pall over the games, leaving viewers to wonder after each win, "Did he take drugs? Did she?"
  • Both Wiese-Bjornstal and Cullen agree that education, beginning with young athletes, is important in the fight against steroid use, as are drug testing and stiffer penalties for those who are caught. They also believe that coaches and parents play an important role in supporting the healthy ambitions of developing athletes.
  • "It's important to teach athletes to know what the consequences are and to learn other training practices that are legal and don't involve taking drugs," says Cullen. "Strive to win, strive for perfection, but do it within the rules of the game."

Howstuffworks "How Performance-Enhancing Drugs Work" - 0 views

entertainment.howstuffworks.com/...printable

shared by anonymous on 01 Dec 08 - Cached
  • Every two years as the Olympic Games begin, we hear about athletes using or at least being tested for performance-enhancing drugs. Every time the Tour de France rolls around, there's talk of possible doping. Sometimes, competitors raise the question when one athlete does particularly well. Other times, tests catch athletes with drugs in their systems. The practice of using artificial substances or methods to enhance athletic performance is called doping. Doping has become such a great concern that the United States formed an Anti-Doping Agency.
  • Why Some Athletes Use DrugsAthletes face enormous pressure to excel in competition. They also know that winning can reap them more than a gold medal. A star athlete can earn a lot of money and a lot of fame, and athletes only have a short time to do their best work. Athletes know that training is the best path to victory, but they also get the message that some drugs and other practices can boost their efforts and give them a shortcut, even as they risk their health and their athletic careers.
  • As far back as ancient Greece, athletes have often been willing to take any preparation that would improve their performance. But it appears that drug use increased in the 1960s. One well-publicized incident happened at the Seoul Olympics in 1988 when sprinter Ben Johnson tested positive for anabolic steroids and was stripped of his gold medal. Athletes may also misuse drugs to relax, cope with stress or boost their own confidence. Athletes may have several reasons for using performance-enhancing drugs. An athlete may want to: Build mass and strength of muscles and/or bones Increase delivery of oxygen to exercising tissues Mask pain Stimulate the body Relax Reduce weight Hide use of other drugs
  • ...7 more annotations...
  • Building Mass and Strength Mass- and strength-enhancing drugs used by athletes include: Anabolic steroids Beta-2 agonists Human chorionic gonadotropin (hCG) Luteinizing hormone (LH) Human growth hormone (hGH) Insulin-like growth factor (IGF-1) Insulin
  • A steroid is a chemical substance derived from cholesterol.
  • he body has several major steroid hormones -- cortisol and testosterone in the male, estrogen and progesterone in the female. Catabolic steroids break down tissue, and anabolic steroids build up tissue. Anabolic steroids build muscle and bone mass primarily by stimulating the muscle and bone cells to make new protein.
  • Athletes use anabolic steroids because they increase muscle strength by encouraging new muscle growth. Anabolic steroids are similar in structure to the male sex hormone, testosterone, so they enhance male reproductive and secondary sex characteristics (testicle development, hair growth, thickening of the vocal cords). They allow the athlete to train harder and longer at any given period.
  • Anabolic steroids are mostly testosterone (male sex hormone) and its derivatives. Examples of anabolic steroids include: Testosterone Dihydrotestosterone Androstenedione (Andro) Dehydroepiandrosterone (DHEA) Clostebol Nandrolone
  • hese substances can be injected or taken as pills. Anabolic steroids have a number of possible and well-known side effects, including: Jaundice and liver damage because these substances are normally broken down in the liver Mood swings, depression and aggression because they act on various centers of the brain In males, the excessive concentrations interfere with normal sexual function and cause: Baldness Infertility Breast development
  • In females, the excessive concentrations cause male characteristics to develop and interfere with normal female functions. The drugs can: Stimulate hair growth on the face and body Suppress or interfere with menstrual cycle, possibly leading to infertility Thicken the vocal cords, which causes the voice to deepen, possibly permanently If pregnant, interfere with the developing fetus

  • I have always talked to my cats. I say their name when I see them, when I pet them and when I feed them. They know their names and come when called. The human voice is calming to a cat. Some cats will respond when talked to, others just look at me, but at least I have their attention. I've had other cats that would answer every question with different sounds. Since I don't speak "cat" it was impossible to understand, though. Cats can remember us by our voices as well. One of our cats named "Graceful Mowser" was sold to some friends of ours and a year and a half later had kittens. They called her "Mouse". We were invited to see the kittens, but the momma kept standing over them so we couldn't see them. I talked to her, "Hi Gracie, what beautiful babies" and she stood back as if she was proud and looked at me intently. I always called her "Gracie". When other people came to see the kittens she still tried to cover them. Later, whenever we stopped by, Gracie would come to greet us as soon as she heard my voice. Otherwise she was naturally shy and would hide whenever anyone came in the house.

  • Eventhough parachutes seem to have been used in China since the 1100s and that Leonardo da Vinci of Italy had invented devices similar to parachutes nowadays, worldwide skydivers state that the French inventor André-Jacques Garnerin is the one to make the first parachute. In 1797 he jumped from a balloon over Paris using a parachute and kept on making other jumps in France and also in England.
  • In World War I , that is between 1914 and 1918, the military began using parachutes in their missions
  • ...6 more annotations...
  • Barnstormers, who were in fact aerial showmen, fired the imagination of aviators and skydivers after World War I. The barnstormers showed airborne performances and parachute jumps and travelled every year throughout the United States. Competitions began as a result of the increase of parachuting awareness. The first contest of accuracy landing was held in 1930 in the Union of Soviet Socialist Republics (USSR).
  • The military used paratroopers in World War II , that is between 1939 and 1945. The paratroopers were parachute-equipped soldiers and had the most famous use on D-Day, the invasion of Normandy (Normandie), France, on June 6, 1944
  • The surplus of nylon parachute equipment after World War II and the fact that the U.S. Army had started the first military sport parachuting clubs, set the grounds of skydiving in the United Dtates, as a pleasant and relaxing activity. The same thing happened in many other countries, and thus , the first parachuting world championships were organized in 1951 in Yugoslavia.
  • Little by little, in the mid 1960, systems specially made for sport parachutes took the place of the military surplus systems. Parachutists started to call this activity skydiving and calling themselves skydivers. In order to improve the opening characteristics and to make them more maneuverable, there were a few sport modifications to military parachutes. A French Canadian kite builder, Domina Jalbert, developed in 1964 the the ram-air design, that has set the tendencies for parachutes in skydiving from then on.
  • Sport skydivers constantly tested new and revolutionary designs and materials. Apart from sport uses , there have also been designed sport-generated designs like military HAHO (high altitude, high opening) designs, smoke jumping designs and many types of equipment for two-person and four-person tandem jumping. The military HAHO designs allowed soldiers to silently fly over large areas. The smoke jumping designs aimed to put firefighters into remote forest fires from low altitude.
  • Skydiving has kept on becoming more and more popular after the late 1980s, and this is because the equipment, that is reliable, lightweight, and easy-to-operate, picture this sport as accesible to many people. The U.S. president George H. W. Bush also jumped , thus increasing the popularity of skydiving.

    This is Catawba Valley Habitat for Humanity's Zero Energy House in the Ridgeview Neighborhood of Hickory, North Carolina. It is considered to be the first Zero Energy home in the entire state. Built in cooperation with Appalachian State University in Boone, the ZEH features passive solar heating, photovoltaic panels, solar hot water heater, rainwater collection for garden use, icynene insulation, polar wall insulated siding, and a geothermal heat pump. As in all of their houses, CV Habitat used 2x6 exterior walls for more insulation, compact flourescent bulbs, high power exhaust fans in the bath, and low-e windows. Working with Advanced Energy (based in Raleigh, NC), CV Habitat also had the heating and cooling bills guaranteed at $17/month, which is not too far below the average for the other houses they build. The ZEH was was finished in Sept. 2005, remained open for a year as an office and educational venue, and was finally dedicated and turned over to a homeowner in early Oct. 2006.

  • There are a lot of different kinds of music. Some of the most popular kinds of music today are rock, techno, hip-hop, and rap. All of those kinds of music affect you in different ways. Other kinds of music are instrumental music, opera, etc. Those kinds of music also affect you. The music that affects you the most is calm music like instrumental or fast music like rock or techno. Rock and techno make you speed up, and instrumental or calm music makes you slow down and feel more calm.

      oooooooooooooooooohhh i didnt know this its kind of off topic but i like it it does have music involved
  • Music can also slow down and equalize brain waves. A brain has 4 kinds of waves. It has beta waves, alpha waves, theta waves, and delta waves. When we do daily activities and experience emotions that’s when we use beta waves. Calmness is when we use alpha waves ,when your sleeping you use theta waves , and lastly when you are in deep sleep or in meditation that is when delta waves are used. When your brain waves are slow that is when you are very calm. Different types of music cause different waves. If you listen to calm music then the waves will drop to delta and theta. If you listen to fast or loud music your brain waves will most likely be alpha or beta.

      Even though there are some difficulties with working towards the alternative fuels, it may prove to be more efficient for smaller things (heat and power to small communities or single buildings) in the long run

  • seek an extra fee on broadband connections and to use the money to compensate rights holders for music that's shared online.
  • Griffin's idea is to collect a fee from internet service providers -- something like $5 per user per month -- and put it into a pool that would be used to compensate songwriters, performers, publishers and music labels.

  • A Crisis In Swimming - A lot has been said and written about drugs in sport. With each passing year, there are more and more of athletes caught taking banned drugs/chemicals that enhance sport performance. In the recent Tour de France cycling race, almost half of the urine samples yielded traces of banned substances. An underlying inference is that anyone who tests positive for drugs is a cheat.

  • Feral cats can minimize rodent problems. While cats cannot hunt rats and mice into extinction, they can keep their populations in check and discourage new rodents from moving into the area. Often feral cats fill in a gap in the current ecosystem. For example bob cats or lynx used to live up and down the East Coast but were hunted ruthlessly and driven away by development. Feral cats are similar in size and behavior to these native feline predators and help to control the same species of small prey animals. Many people enjoy watching feral cats and observing animals has been shown to lower blood pressure in medical studies. People who help to care for feral cats by feeding them and taking them to the vet enjoy many benefits. Often cat caretakers are elderly and live alone, a population at risk for depression, loneliness, and isolation. Cats relieve these conditions and often bring a sense of happiness and purpose to people who help them. Just as companion animals have been shown extend life expectancies, lower blood pressure, and relieve stress, caring for feral cats improves the health of their caretakers. Individuals who cannot take on the full time commitment of adopting a companion animal can participate in programs to help feral cats. This provides a viable alternative to irresponsibly purchasing an animal one is not prepared to care for. An established, stable, vaccinated, and sterilized colony of feral cats will deter other stray and feral cats from moving into the area. This actually decreases the risk that residents will encounter an unvaccinated cat, and will virtually eliminate problem behaviors like fighting and spraying.
