Seven time consecutive Tour De France champion and yellow rubber band seller of the decade openly admitted to blood doping. His name was Lance Armstrong and not only did he live through cancer, but he was one of the greatest athletes the world has ever known. His list of achievement goes on until his banishment for professional racing and the stripping of his titles. He admitted to using banned substances including steroids and blood doping in an interview with Oprah Winfrey on January 17, 2013. Why would a man with so many accomplishments cheat the system with prohibited procedures and the use of illegal performance drugs? The three topics that rise in answering why Lance Armstrong blood doped is explaining what blood doping is, the advantage and disadvantages of it and drug use in profession sports.
To describe what blood doping is one must first understand some key terms. Hemoglobin is a red protein responsible for carrying oxygen in your blood. Another key term is the cardiovascular system and this is an organ system that distributes the blood throughout the body to deliver nutrients and remove waste. And the respiratory system is the organ system that carries out gas exchange in your body. These three things all work together hand in hand like a smooth operating clock. The respiratory system gets the oxygen from the air and transports it to the blood carried in the hemoglobin. The oxygen enriched hemoglobin rides along the cardiovascular system to get to the needy muscles and deliver the oxygen to them. Mitochondria in the muscle cell use the oxygen in cellular respiration to generate ATP. The ATP is the energy the muscle cells need to operate. All functions in the human body need ATP. The production of ATP is dependent on an adequate supply of oxygen and without oxygen ATP production stops.…...

...getting new avenues of earning name and fame, recognition from their country and also from world’s media. Then if one looks at Company's (Inner self, Family, Brands, and Country) point of view it’s always good that their employee mark their manifestation (unless it isn’t effecting Company’s reputation or rather it isn’t naked). And when it comes to peers (if they are too true to their company) one is being egocentric because there is matter of being promoted with more than just a Gold Medal. And this also may arouse interest of their peers to opt the enhancement therapy (which can be better for company). So one can’t be exactly sure of favouring doping which is better for sport and sportsman but only in short run. Different Kinds of Drugs used in Sports: The practice of taking remedial measures for performance enhancing is called Doping in Sports. There are different performance enhancing drugs for different requirements of an athlete, depending upon the sports and the core competence required for realisation of objective. • Stimulants – Caffeine, Amphetamine, Cocaine Many athletes have to follow strict guidelines for diet and also they have many social obligations. And this leads to stress of being a public figure, weight issues; so for that sportsmen seek help from drugs. • Build Muscle/ Bones - Anabolic Steroids, Insulin Anabolic steroids help in increasing the strength by promising new muscle growth. • Relaxants- Alcohol, Beta-blockers,......

Physiological Effects of Blood Doping

...received a large amount of praise and was even awarded the title “Man of the Year” by the United States Cycling Federation (USCF). To the world’s surprise, a scandal was about to be unveiled. Robert Lea, president of USCF, sent a letter to members of the board, in which he stated his resignation from his position as president because investigation showed that the United States coaching staff “blood doped” some of the Olympic cyclists. But what was blood doping, and why was it such an issue? Blood doping is the practice of increasing the number of red blood cells (by artificial means) in the bloodstream. With an increase of red blood cells, more oxygen can be carried from the lungs to the muscles, which can improve aerobic capacity. This blood doping procedure gained notoriety in the sports world because of what it can do for athletes during endurance events and the jeopardizing effects it could have on the cardiovascular system. Basically, in order for muscles to perform they need a need a ready supply of oxygen. This is especially true in endurance sports. For example—Jake, a non blood doper is a marathon runner. During high intensity runs, his oxygen levels increase for the first few minutes, and then a plateau follows shortly after. The plateau suggests that there is a balance between energy required by working muscles and the production of ATP by the body. When Jake reaches this plateau, he is reaching his maximal oxygen uptake, which means he can no longer increase......

The Advantages and Disadvantages of Blood Doping

...The Advantages and Disadvantages of Blood Doping Over the past years, there have been many technological advances in the field of medicine. Some of them have proven to be extremely beneficial in creating a healthier society while others have been used for personal gain. The following essay will outline one of these advances, which is the medical phenomena of blood doping, also known as blood boosting and blood packing. There has been much controversy surrounding the use of blood doping ever since it has gained mainstream publicity. From a medical and an ethical perspective, many consider the use it wrong and immoral. In the following paragraph, we will briefly introduce this concept by describing the process and how it can be utilized. Later on, we will discuss the advantages and disadvantages of employing blood doping. Blood doping is a medical process used to increase the concentration of red blood cells in one’s body to a higher, supraphysiologic level (Shah 167). Athletes who would like to give themselves an advantage competing physically most commonly use it (Foschi, 458). This procedure can be achieved in two different ways. One can ask to have his or her own blood injected or can request the use of the blood of a matching donor. These processes are respectively called autologous and monologous transfusions. The red blood cells are usually removed over an extended period of time. The withdrawn blood is then refrigerated for preservation and finally......

...Quality of Red Blood Cells Isolated from Umbilical Cord Blood Stored at Room Temperature Mariia Zhurova, 1 John Akabutu, 2 and Jason Acker 3 ,* Author information ► Article notes ► Copyright and License information ► ------------------------------------------------- Abstract Red blood cells (RBCs) from cord blood contain fetal hemoglobin that is predominant in newborns and, therefore, may be more appropriate for neonatal transfusions than currently transfused adult RBCs. Post-collection, cord blood can be stored at room temperature for several days before it is processed for stem cells isolation, with little known about how these conditions affect currently discarded RBCs. The present study examined the effect of the duration cord blood spent at room temperature and other cord blood characteristics on cord RBC quality. RBCs were tested immediately after their isolation from cord blood using a broad panel of quality assays. No significant decrease in cord RBC quality was observed during the first 65 hours of storage at room temperature. The ratio of cord blood to anticoagulant was associated with RBC quality and needs to be optimized in future. This knowledge will assist in future development of cord RBC transfusion product.

Why We Should Regulate Doping in Sports

...“Nothing was being done to help the non-dopers, to encourage or support them. Even the clean riders like myself and Moncout knew how easy it was to cheat the tests" (Millar). In Jeremy Rozansky's article "How to Think About Our Steroid Supermen" he discusses the use of performance enhancing drugs (PEDs) in sports and how the use of these drugs is unethical because it goes against the sportsmanship spirit of the game. Rozansky also talks about the many ways doping is dangerous and can compromise the health of the athletes involved. He states his opinion that doping in sports sends a bad message to children-that drugs make champions. While these are valid points, However, if PEDs in sports were allowed and regulated, not only would it help the athletes improve performance, it would also make doping safer for the athletes as limits could be set on how much an athlete can use/have in their system. By regulating doping in professional sports, not only would this help keep athletes from injuring themselves, it also has the potential of improving the entertainment of spectating the sports by leveling the playing field even more and allowing for even greater spectacular feats to occur. Lance Armstrong was a role model. Not only did he survive cancer, despite having brain and lung metastases, he came back to win the most grueling race in sports, the Tour de France, a record 7 times. He was an icon, but that time has passed. In Rozansky's article he argues that Lance, and other......

Blood

...Blood is very important to our bodies for many reasons; it carries oxygen to our vital organs, as well as important vitamins and minerals to other parts of the body. It also helps to regulate the PH balance as well as our bodies’ temperature. But most importantly, it carries white blood cells which are very important for our immune system. If we have problems with our blood supply, we can develop anemia or leukemia, and this may affect how our bodies function. Worse yet, if not getting it properly taken care of, it may result in a host of complications or even death. Plasma is a yellow liquid form portion of our blood that replaces easily thru out our bodies, consisting of water and proteins, and that helps control infections as well as bleeding. They are responsible for carrying oxygen thru out our body. Platelets are responsible for making our blood clot, which enables us from bleeding to death. Clotting when it dries out produces scabbing which aids in the healing process. Leukocytes or white blood cells are germ fighting cells, and there are two types: phagocytes (they help get rid of germs) and lymphocytes (which act as memory cells that can recall their last attackers). White blood cells can be found in places like the spleen, the bone marrow, and it has a sponge gel like consistency. Lily: Her poor eating habits are creating some serious health issue.

Doping Notes

...athletes who choose not to dope, choose not to be in their strongest shape (minus the possible side effects of doping) and go against their motto. Documentary-ish: http://www.youtube.com/watch?v=IPnT1ZSXfaU * This video basically follows this body builder around as he talks about steroids and body building. * This video shows how athletes feel like they are not performing their best if they choose to not use steroids. * This video also shows how body builders felt when they found out their role models (Sylvester Stallone, Schwarzenegger) * Athletes who choose not to dope fall into conventional thinking as they abide to the regulations of the sport, rather than the outcomes made possible by winning. If an athlete chooses not to dope and loses to someone who does, they directly fall into conventional thinking. Post conventional thinking would be if the athlete dopes despite the regulations, wins, and brings home wealth to his benefactors. This thinking is considered utilitarian and can be considered rights based if his opponents doped as well. * As evidenced in Lance Armstrong’s case, he was able to dope for years and received the benefits of winning. This suggests two things. * Doping can be done successfully without the consequences of getting caught. * Lance lives the life of a very successful athlete despite admitting to his doping. This proves the example of post conventional thinking ~ utilitarian. Article:......

Doping

...My friend was being recruited by a D1 university for football and was given multiple items of great value to play for them. 2. In 1972 a GDR sixteen-year-old swimmer was found dead in the pool from overtraining/ doping complications. Other examples of overtraining are the female/male now Andrea’s caused irreversible damage to her hips and thighs. As Katharina Bullin could play volleyball anymore because of the wear on her body. 3. Yes, I can make sense of the varying responses of the athletes being doped. These children and teenagers had no idea that they were being experimented on until it was to late and their bodies have already been broken down. No matter what the athletes think their medals are all tainted because they did not earn them the drugs did because of the physical advantage they offered the GDR athlete. 4. I feel that cheating in sports is a norm because it’s been around since sports have been around. Someone is always looking at how to beat the system and get a physical advantage over everyone and history has proven that. Alex Rodriguez, Chris Phillips, Lance Armstrong, Melisa Price and several other athletes have been caught for doping in U.S. sports. No “Doping for Gold” has not changed my opinion because I still feel that doping is terrible and you should be stripped of your medals and banned from the sport for life. It needs to stop and we all need to keep the games clean. 5. I found it to be very interesting that the GDR girls never......

...May 5, 2015 Anatomy and Physiology Tell Me About Blood 1. A lower than normal hermatocrit means that a person is anemic. You may have heard your parents say, ‘I think my blood is low”. 2. Lymphopoiesis is the development of lymphocytes, which are which blood cells. Erythropoiesis is the development of erythrocytes, which are red blood cells. Myelopoiesis is the development of myelocytes, which are young blood cells. Granulopoiesis is the haematopoiesis of grandulocytes, which is also a white blood cell, but it is in the cytoplasm. Megakaryocytopoiesis is haematopoiesis of megakaryocytes, which are responsible for the production of blood platelets. 3. Erythropoiesis is the production of red blood cells. The factor that speed up and slow down erythropoiesis is when the kidneys release a factor that changes a blood protein to erythropoietin. This hormone targets the bone marrow where immature precursor cells are induced to synthesize large amounts of hemoglobin, the oxygen protein of red blood cells. Erythroblasts become reticyclocytes, immature red blood cells released into the blood stream where they mature into erythrocytes, full-fledged red blood cells, in one or two days. 4. Nothing negative will happen if a person who is blood type B is given a transfusion of the blood type O because blood type O is the universal donor and can be given to any blood type. 5. White blood cells contain small, pale, lilac granules and a......

Doping in Sports

...Doping in sports is a serious matter and should not be used for any sport for numerous reasons. These types of drugs come with serious health risks. First, there are many dangers to the body from steroids. Second, it is just unfair to other players and athletes. Thirdly it could possibly cause a crash in an athlete’s career if getting caught. Steroids and other performance enhancing drugs, PED’s, are very harmful to the body. It is not worth the risk of permanent damage to the body and organs. Most PED’s contain hormones which will cause extreme behavioral changes. People who take PED’s act more aggressively, are more likely to sexually harass somebody, and are generally more violent. So just from taking these drugs the users are effecting their and people that they are with lives outside of sports. The use of any PED is unfair to other players because they are not competing against a person its, the drug. It takes out the spirit of competition. A player that has been on a steroid has an unfair advantage due to the power gained from the drug and not the body. It is basically a form of cheating. PED use can cause a crash in an athlete’s career if they are caught using the drug, because if it gets on the news it would give him/her a bad reputation, the drug will cause the downfall of the athletes career and possibly get the player kicked off the team, it’s a shocking matter for the fans to find out and also winning without relying on drugs is a real accomplishment to a......

...The Rh factor (ie, Rhesus factor) is a red blood cell surface antigen that was named after the monkeys in which it was first discovered. Rh incompatibility, also known as Rh disease, is a condition that occurs when a woman with Rh-negative blood type is exposed to Rh-positive blood cells, leading to the development of Rh antibodies. Rh incompatibility can occur by 2 main mechanisms. The most common type occurs when an Rh-negative pregnant mother is exposed to Rh-positive fetal red blood cells secondary to fetomaternal hemorrhage during the course of pregnancy from spontaneous or induced abortion, trauma,[1] invasive obstetric procedures, or normal delivery. Rh incompatibility can also occur when an Rh-negative female receives an Rh-positive blood transfusion. In part, this is the reason that blood banks prefer using blood type "O negative" or "type O, Rh negative," as the universal donor type in emergency situations when there is no time to type and crossmatch blood. The most common cause of Rh incompatibility is exposure from an Rh-negative mother by Rh-positive fetal blood during pregnancy or delivery. As a consequence, blood from the fetal circulation may leak into the maternal circulation, and, after a significant exposure, sensitization occurs leading to maternal antibody production against the foreign Rh antigen. Once produced, maternal Rh immunoglobulin G (IgG) antibodies may cross freely from the placenta to the fetal circulation, where they form antigen-antibody......

Blood Donation

...Health Care Market-Blood Donation Health Care Market- Blood Donation According to Wikipedia, blood is a specialized bodily fluid that delivers necessary substances to the body’s cells, such as nutrients and oxygen, and transports waste products away from those same cells (Wikipedia, 2011). There has been a high demand for blood, all types of blood. Statistically speaking someone in the United States needs blood every two seconds (Rare Blood Types, 2010). Due to the high need for blood, scarcity plays a role with blood donation. This paper will discuss how scarcity resources influence the market, and the choices stakeholders are forced to make. The essay will also relay the economic flows that may affect the health care market, the causes of change in supply and demand and the affects of equilibrium price and quantity, and the pricing decisions for blood donations with elasticity or inelasticity. A resource is considered scarce when its availability is not enough to meet its demand. Scarcity is based on the idea that oftentimes a limited supply of goods or services comes up against an ever increasing demand for it, and that ever effort must be made to ensure its proper utilization and distribution to avoid inefficiency (International Society for Complexity, Information, and Design, 2005). Blood is needed for many individuals, whether it is for someone that has trauma, needed surgery, needed blood transfusion, cancer patients, etc. More than 38,000 blood......
