The Bispebjerg Hospital anti-doping researcher has worked on many scientific studies, including a 2008 paper co-written with Belhage and Damsgaard entitled Changes in Blood Profiles during Tour de France 2007, and stated that expected trends over a three week race were not seen in the Texan’s data.
"What we know from our research is that during periods of hard activity, like in the Tour de France, we normally see a drop in these blood values. We don't see this with Armstrong," he told DR Sport.
He elaborated on this when speaking to Cyclingnews. “His blood profile contradicts what we see and what we know from international studies during the last few decades,” he said in a phone interview. “His blood values are not acting as we would expect, so that is highly unusual.” (see sidebar)
Mørkeberg has just finished a Ph. D. dissertation entitled Detection of Autologous Blood Transfusions via Analyses of Peripheral Blood Samples, and is working on a method to trace this method of doping.
His aforementioned Tour de France study catalogued seven riders in the 2007 race, revealing lower hemoglobin and lower hematocrit (percentage of red blood cells in whole blood) on day 19 when compared to their pre-Tour reading. On average hemoglobin dropped 11.5% and hematocrit fell by 12.1%, keeping in line with physiological expectations.
