They didn't stop after the EPO era wrote:
I get how the superhuman times are really suspicious, but I can't bring myself to 100% believe that Kenenisa Bekele and Haile Gebrselassie were taking EPO.
There was a lot of EPO in the 90's, but Kenenisa Bekele's career really started around 1999-2000. Haile Gebrselassie was consistently putting down fast times far after the 90's; Haile set the Marathon WR in 2008 and continued running fast until 2012, while Bekele kept eventually ran a 2:03 marathon in 2016.
People knew that Bekele was a special talent for a long time (
http://www.letsrun.com/forum/flat_read.php?thread=58776), and even in 2002 people doubted his ability to break records after the EPO era (look at 1st reply).
If people could only get away with EPO in the 1990's and 2000's, how were both Bekele and Gebrselassie still able to run so fast 20 years into their career, after the EPO era? It's this that I don't understand.
Science has prevailed, and EPO is old news. Quote:
Have you ever wondered what Usain Bolt, Ronaldo, Michael Jordan, Paula Radcliffe, etc. all have in common?. .
. . . A recent piece in the New York Times (link) discussed the sub-2-hour marathon project, and in it, it chronicled the struggles of world record holder Kenensia Bekele in his attempt to return to racing form. The article mentioned a German doctor, Hans-Wilhelm Müller-Wohlfahrt, and a distant bell was rung in my brain, as I had heard this name associated with other big athletes (the article even mentions Usain Bolt) and his unconventional treatment methods.
. . .So for comparison, the infamous performance-enhancer for endurance sports (and likely many other sports) is EPO. As we all know, EPO increases the number of red blood cells in your body, thereby delivering more oxygen to the muscle cells. Actovegin essentially helps the muscle cells use that oxygen more efficiently. This ability to enhance O2 flux and glucose-derived energy-utilization on the mitochondrial level may be ringing bells for the scientific minds out there. Indeed, this mechanism is similar to the drug that most recently dominated headlines: Meldonium. Maybe Maria Sharapova has a ‘legal’ alternative (though one can’t help but suspect it may have already been in the medicine cabinet…)!
