Blood doping methods -

Preliminary results from her work have so far produced no evidence of any relationship between intense exercise in hot weather and false positive results, which could provide much-needed credibility and authority for the World Anti-Doping Agency's current methods.

Dr Caillaud's work responds to an alarming lack of research on the impact of physical exercise on markers of EPO abuse in the context of elite sports. Record-breaking temperatures during the Ashes cricket test match in Sydney led many to wonder: how hot is too hot to continue playing sport safely?

Dr Adrian Cohen from the University of Sydney explains what causes a concussion and how to best prevent them. Improved blood doping detection protects sport and athletes.

Dr Corinne Caillaud of the University of Sydney researches the impact of physical activity on doping tests to help prevent false positive results.

A few years after the Mexico Games, and through the s and s athletes used transfusions to blood dope. That method wasn't banned until , after the Los Angeles Olympics, where the U.

cycling team boasted about their use of transfusions. There are two methods of using transfusions for blood doping, plus other methods that use substitutes and hormones. For transfusions, there's the standard method, using blood from someone of the same blood type. The hemoglobin in the transfused blood increases the amount of hemoglobin in the recipient's bloodstream.

That's called homologous transfusion. Another method used by athletes is transfusing their own blood, which is called autologous transfusion.

Hospital patients awaiting elective surgery sometimes choose this method to avoid infections and blood type match errors.

Athletes have their own blood withdrawn, preferably when their hemoglobin level is high, stored and then re-infused before a competition. The athlete's blood could also be run through a centrifuge to isolate red blood cells from blood plasma.

In , Spanish police raided a cycling team doctor's office in Madrid and discovered 99 bags of athletes' blood allegedly being stored for later transfusion. American cyclist Tyler Hamilton, an Armstrong teammate, was investigated by the IOC during the Athens Games, after his initial sample indicated he had tested positive for a blood transfusion but the case was dropped after his backup "B" sample was mistakenly frozen and couldn't be properly tested.

The IOC stripped him of the medal in August. It took 20 years until a successful test was developed in for homologous transfusions, which involves using another person's blood, but experts are still confounded by the use of an athlete's own blood. Cyclist Niklas Axelsson tested positive for EPO in Cyclist Tyler Hamilton failed a fluorescent-activated cell sorting test for detecting homologous blood transfusions during the Olympics.

He was allowed to keep his gold medal because the processing of his sample precluded conducting a second, confirmatory test. He appealed a second positive test for homologous transfusion from the Vuelta a España to the International Court of Arbitration for Sport but his appeal was denied.

Hamilton's lawyers proposed Hamilton may be a genetic chimera or have had a ' vanishing twin ' to explain the presence of red blood cells from more than one person. While theoretically possible, these explanations were ruled to be of "negligible probability".

Tour de France rider Alexander Vinokourov , of the Astana Team , tested positive for two different blood cell populations and thus for homologous transfusion, according to various news reports on July 24, Vinokourov was tested after his victory in the 13th stage time trial of the Tour on July 21, A doping test is not considered to be positive until a second sample is tested to confirm the first.

Vinokourov's B sample has now tested positive, and he faces a possible suspension of two years and a fine equal to one year's salary. Vinokourov's teammate Andrej Kashechkin also tested positive for homologous blood doping [45] on August 1, , just a few days after the conclusion of the Tour de France a race that had been dominated by doping scandals.

His team withdrew after the revelation that Vinokourov had doped. According to Russian investigators, year-old New York Rangers prospect and Russian hockey player Alexei Cherepanov was engaged in blood doping for several months before he died on October 13, , after collapsing on the bench during a game in Russia.

He also had myocarditis. The German speed skater and five-fold Olympic gold medalist Claudia Pechstein was banned for two years in for alleged blood doping, based on irregular levels of reticulocytes in her blood and the assumption that these levels were always highest during competitions.

Her mean reticulocyte count over the ten years from to was 2. At world cup races the mean reticulocyte was 1. once the possibility of a blood disease has been safely excluded On May 20, , Tyler Hamilton turned in his Olympic Gold Medal to the U.

Anti-Doping Agency [50] after admitting to doping in a 60 Minutes interview. On August 23, , Lance Armstrong was stripped of his seven Tour de France titles and banned for life by cycling's governing body following a report from the U. Anti-Doping Agency that accused him of leading a doping program during his cycling career.

He later admitted to using banned substances including blood doping with transfusions and EPO in an interview with Oprah Winfrey on January 17, In June , UFC fighter Chael Sonnen tested positive for EPO.

In February , Bahraini steeplechase and m steeplechase world record holder Ruth Jebet tested positive for EPO and in the 4th of March, she was suspended for 4 years. The simple act of increasing the number of red blood cells in blood may be associated with hyperviscosity syndrome which is characterized by increased blood viscosity and decreased cardiac output and blood flow velocity which results in the reduction of peripheral oxygen delivery.

This increases the chances of heart attack, stroke, phlebitis , and pulmonary embolism , which has been seen in cases where there is too much blood reintroduced into the blood stream. Because blood doping increases the volume of red blood cells, it effectively introduces a condition called polycythemia , a blood disorder that has known adverse outcomes such as heart attacks or strokes.

Blood contamination during preparation or storage is another issue. Contamination was seen in 1 in every , transfusions of red blood cells in Certain medications used to increase red blood cells can reduce liver function and lead to liver failure, pituitary problems, and increases in cholesterol levels.

Improved blood doping detection protects sport and athletes - The University of Sydney	For the time being, the storage of athletes' blood samples to allow testing and sanctioning of guilty athletes once a definitive test has been introduced may represent a reliable deterrent policy. Abstract Blood doping consists of any illicit means used to increase and optimize oxygen delivery to the muscles and includes blood transfusions, administration of erythropoiesis-stimulating substances, blood substitutes, natural or artificial altitude facilities, and innovative gene therapies. Substances Blood Group Antigens Hemoglobins Erythropoietin. Three weeks after the last EPO injection, only two out of 48 urine samples showed up as positive in lab tests. Nonetheless, the total red blood cells and aerobic capacity of the participants were still elevated at that time. That's just one of the reasons EPO urine tests, which began in , have been fraught with challenges. In addition, EPO is short-lived, remaining in the body for as short a time as two days. But the performance effects, he added, can remain for 90 days or so. In addition, cheating athletes and those who administer their drugs constantly work to sneak under the testing radar, finding the lowest doses possible that still have performance effects or figuring out when to inject the drugs to beat testing. Blood doping, when successful, involves more than acclaim, broken records and winning medals. Serious health effects also can come into play.

During the storage period the body is able to restore all or almost all of the withdrawn blood. The athlete then injects the stored blood via blood transfusion the day before a race or match. Blood doping was banned by WADA the World Anti-Doping Agency in The idea is that unexplained fluctuations in biological variables for instance, hemoglobin content in the blood, hematocrit value , or the number of new, immature red blood cells, called reticulocytes could indicate doping, even though some doping methods cannot be detected directly. Nine healthy, well trained men with an average age of 29 years participated in the study. They had at least three years of experience in endurance sports cycling or triathlon. The men participated in two rounds of experimentation. They randomly received either a blood transfusion or a placebo in the first round of testing. In the second round of testing they received the opposite. The study was blinded for both the test manager and test subjects. In both rounds of testing the subject performed a time trial of approximately 40 minutes on an ergometer bike before and after receiving a blood transfusion of their own blood or a placebo.
Blood doping - Wikipedia	Aerobic Capacity is also referred to as VO2Max. Someone like Greg Lemond has a massive stroke volume and VO2max of The junior time trial world champion Oskar Svendsen is reported to have the highest VO2 Max ever recorded in a human at The only variables in VO2max that you can manipulate to improve it is by reducing your bodyweight, or increasing your haemoglobin mass. In aerobic sports such as cycling, the main factors determining performance are the high delivery of oxygen to the exercising muscles and its use. With cardiac output, our maximum achievable heart rate goes down as we all age. Mitochondrial respiratory capacity is inherited from your mother. The only variable that remains open for manipulations with regards to increasing performance is the hemoglobin concentration and blood volume the left side of the diagram. This is the basis of blood doping. Athletes can either cheat by injecting EPO or transfuse red blood cells to elevate the haemoglobin mass. Both will achieve the same endpoint. Tyler Hamilton described some slight differences in his book however. Altitude training is legal in most countries but banned by in Italian. Higher levels lead to EPO wastage, and lower levels cause inefficient red blood cell production. There are a couple different strategies when taking EPO. There is the high dosage X UI per kilogramo of body weight 3 times per week strategy which athletes use to elevate blood levels but is much more easily detected. The low dose strategy is called micro-dosing and involves the athlete using high dosages of EPO initially to get his levels up, and then maintains them with low dosages. Image photoshopped Transfusing blood RBC Transfusion. There are two types of blood transfusions: Autologous and homologous. If not, your body will react to it as foreign substance and destroy it. You read about Tyler Hamilton urinating blood in his book. This is one of those reactions. In its worst form, you can die from this incompatible reaction. You can dope this way and match the major similarities in blood. If they match, you are unlikely to have any problems. Homologous transfusion can be detected by testing for minor incompatibilities. Even if you get all the major similarities right, there are other complications that can arise that will create a reaction. You might ask why somebody would risk a homologous transfusion when his own blood could be used. There are a couple reasons. The use of blood transfusion, an extremely straightforward, practical and effective means of increasing an athlete's red blood-cell supply in advance of competition, became rather popular in the s, but it has suddenly declined following the widespread use of recombinant human erythropoietin among elite endurance athletes. Most recently, following implementation of reliable tests to screen for erythropoiesis-stimulating substances, blood transfusions have made a strong resurgence, as attested by several positive doping tests. Doping by blood transfusion can be classified as homologous, where the blood is infused into someone other than the donor, and autologous, where the blood donor and transfusion recipient are the same. The former case produces more clinically relevant side effects, but is easily detectable using current antidoping protocols based on erythrocyte phenotyping by flow cytometry and, eventually, erythrocyte genotyping by DNA testing. Since the donor and recipient blood are identical in autologous blood doping, this is less risky, though much more challenging to detect.

This allows the body to transport more oxygen to muscles and so increase stamina and performance, making it particularly effective for endurance events. There are three widely known substances or methods used for blood doping: injections of erythropoietin EPOsynthetic oxygen carriers and blood transfusions. EPO, which was used by Lance Armstrong throughout his cycling career, is a hormone released from the kidneys that acts on bone marrow to stimulate red blood cell production.
