The world was shocked when world #11 and five-time grand slam singles champion, Maria Sharapova, was suspended from tennis competition for use of a banned substance, meldonium. The tennis world reacted with scorn for the former world #1 women’s tennis player:

• John McEnroe: “It would be hard to believe that no one in her camp, the 25 or 30 people that work for her, or Maria herself, had (any) idea that (meldonium had been banned).”
• Jennifer Capriati: “I didn’t have the high priced team of [doctors] that found a way for me to cheat and get around the system and wait for science to catch up.”

Capriati is making the most powerful case against doping from an athlete’s perspective. Taking banned or illegal drugs to enhance performance is cheating. And to not call out cheats is unfair to those who are not taking drugs that give advantage.

Sponsors dropped Sharapova like an overripe fruit with maggots inside. All except Head, the racquet manufacturer.

According to this statement from HEAD, “We question WADA’s decision to add meldonium to its banned substances list in the manner it did; we believe the correct action by WADA would have been to impose a dosage limitation only. In the circumstances we would encourage WADA to release scientific studies which validates their claim that meldonium should be a banned substance.”

WADA is the World Anti-Doping Association, the international governing body that establishes what athletes may or may not put into their bodies. The president of WADA, Dick Pound responded to HEAD’s statement to the BBC:

“First and foremost, Head is a manufacturer and seller of tennis rackets, among other things. So far as I’m aware, it’s not a medical expert and not in a position to amend the world anti-doping code. As for its view as a commercial racket seller as to whether meldonium should be on the list of prohibited substances or not, quite frankly I prefer the scientific opinion of medical experts to the commercial interest of somebody telling tennis rackets using a player who is subject to whatever discipline is called for under the world anti-doping code. A complete conflict of interest on its part, combined with a lack of knowledge of the particular substance.”

That is a powerful and damning retort from Pound, whose efforts helped lead to the suspension of Russia’s entire track and field team from international competition, including the upcoming 2016 Rio Olympics.

And yet, this is what confuses me. There doesn’t seem to be any consensus among “medical experts” as to whether meldonium actually enhances performance in athletes.

This New York Times article explains the science of how meldonium works. In short, burning glucose in your body releases more energy than burning fat. The “science” states that meldonium will work to encourage the burning of glucose, not fat. So when you’re oxygen starved, a situation many high-performance athletes find themselves in when they exert themselves, the meldonium will give them a glucose burn and a bigger burst of oxygen.

The same New York Times article, entitled “Effects of Meldonium on Athletes are Hazy“, quotes Dr Eric Brass of UCLA, who questions the correlation between meldonium and greater athletic performance.

“In general, if one is involved in short-duration, sprint-type activity, one tends to use glucose because it is more available and it is an efficient way to generate energy quickly,” said Dr. Eric Brass, a professor of medicine at U.C.L.A. Still, Brass said it was not clear if that was what was really happening in athletes. “The science behind many of these performance-enhancing compounds is limited, biased and subject to misinterpretation,” he said. Several of the studies on meldonium were done on rats and published only in Russian.

This is why doping stories outrage me and put me to sleep at the same time. I definitely
