Here's what I wrote in the "Rosa" thread:
You can refer to previous explanations, because there is no need for me to change any.
Athletes take drugs based on belief and hope. Sometimes it works. Sometimes they get busted.
Belief in drugs in the hope of improved performance is deep and wide -- for many examples, just visit forums like letsrun.
Given the circumstances around Sumgong, Chepchirchir's suspension was predictable.
I forgot to mention that the validity of "proofs by example" does not change by adding one more example.
I trust the AIU will do what they can to determine her guilt, and do not offer any excuses for her (or anyone's) doping.
If you want to start a performance discussion, you need more data.
Some interesting info on doping & elite performance:
http://nymag.com/speed/2016/12/how-much-faster-could-the-fastest-human-on-the-planet-be.html"There are three broad classes of performance-enhancing drugs, including those that make athletes stronger, such as testosterone; those that improve endurance, such as EPO (erythropoietin); and stimulants, such as amphetamines, which sharpen an athlete’s focus and can quicken reaction time at the start of a race. An athlete may take these substances by themselves or in conjunction with others.
“Every imaginable cocktail has been tried,” says Dr. Michael Joyner, a physiologist at the Mayo Clinic. “This is the devil’s playground.”
"Testosterone, the most well-known doping drug for sprinters, is an anabolic steroid that improves the synthesis of muscle protein and can provide a runner with increased power and speed. It comes in many forms, such as a time-release pellet the size of a grain of rice that gets inserted through a tiny incision in the skin, or as a candy, like a Life Saver, in 28 different flavors, including “tutti frutti” and “piña colada.” But it’s most difficult to detect when it’s used as a fast-acting cream or gel, which can be applied directly to the skin, and therefore enter one’s bloodstream directly. Using this method, the steroid “will peak in your bloodstream in three or four hours and then by six hours later you’re back down to the allowable limit,” says Victor Conte, who as the founder of Balco, a California nutritional supplements lab, pleaded guilty in 2005 to distributing anabolic steroids to athletes. Several of track and field’s top runners were among those linked to Balco at the time."
*This is very interesting with rEPO & sprinters:
"The most powerful banned substance for sprinters, says Conte, who now runs Snac System, an all-natural sports-nutrition company, is EPO. While it is more often associated with improving results for long-distance runners because of its ability to increase oxygen intake, EPO allows sprinters to do more training repetitions and to do them more intensely. “The deeper the training load long-term throughout an off-season, the greater the gains,” Conte says."
"As Joyner points out, “One of the things that people fail to recognize about doping in general is that it facilitates harder training.”
"Nearly as powerful as EPO is the insulin-like growth factor IGF-1, another fast-acting injectable substance that aids a runner’s recovery from training. Yet, according to the United States Anti-Doping Agency, “although IGF-1 can be identified in urine, there is no current criterion for detecting abuse in this way.”
The lozenges are currently virtually impossible to detect, hence WRs keep improving.
