Armstrong wins the time trial and wins the tour to France in professional sports the stakes are high athletes want to win it's you versus the clock you versus the other competitors you against yourself late is there any stopping in this to FR and there's big money some will do whatever it takes to be the best we live in a performance- enhanced world so so we have performance enhancing drugs and sports Mayo Clinic Dr Michael Joiner is an an theologist whose research focuses on understanding Elite athletes how they reach maximum performance he says it's all about
oxygen delivery to the body's tissues one of the things that determines the maximum ability of somebody to use oxygen is how many red blood cells they have circulating around in their body blood doping is an effort to raise the number of blood cells by taking Blood Out storing it and then reinfusing it later red blood cells carry oxygen to the body's tissues when the stored blood is returned to the body there's a sudden boost of red blood cells those cells carry higher than normal amounts of oxygen to muscles enhancing performance the other thing people do
is use a drug called arthropo or EPO to boost the body's natural production of red blood cells an injection of epo stimulates your bone marrow to make more red blood cells boosting levels of oxygen getting to your muscles and boosting performance just kind of the body's own own Factory that makes red cells gets cranked up both techniques are not just for athletic enhancement they're also needed in the medical world EPO is used to help keep up red blood counts such as for people on dialysis and removing blood to put back later is common during surgery
you're not going to stop the onslaught of L's AR still blood doping for performance enhancement is illegal in the Sports World and Dr Joiner suspects that as long as the stakes are high some athletes will be tempted to dopee I think the athletes would tell you that they would be happy to not dope if they were convinced the playing field was level for Mayo Clinic News Network I'm Vivian Williams
