The above interview is from 2009 and titled "Too Many Drug Tests In Beijing". Asafa Powell and Tyson Gay are a part of an athlete panel at the 2009 Reebok Indoor Grand Prix. Powell says he was tested four times in one week in Beijing and it was "too much," while Gay said he is tested regularly all year, so he didn't find the Games' testing to be exceptionally intolerable. Although according to the USADA database, they only administered three tests to Gay in 2009. In 2013, both Powell and Gay served bans for testing positive for illegal substances.

Matt Centrowitz was tested by the U.S. Anti-Doping Agency 17 times in 2016. The next most tested athlete? Carmelita Jeter, who at age 37 failed to dip under 11 seconds in the 100m in 2016, was tested 15 times.

You can view the number of times an athlete was tested by USADA by year at this link. However, this number only indicates "the number of times USADA has organized a test on an individual athlete", meaning it doesn't include other testing entities' numbers, if the test was not requested/initiated by USADA, and other sports organization/event/International Federations/individuals' requests for tests.

The total numbers, minus athletes' names, are available at this link. And it's also interesting to note that track and field is the MOST tested sport by USADA. Between in competition and out of competition tests administered by USADA, track and field had 2785 total tests conducted in 2016.

Mixed martial arts had 2289, cycling 1398, and swimming 1071.

So what does this mean? Can you really make conclusions from simply looking at testing numbers? Justin Gatlin and Galen Rupp were tested 14 times in 2016, but compared to '15 (21 times), '14 (21 times) and '13 (28 times), this was one of Rupp's lowest years.

Here are all 481 athletes from the 2016 USADA database:
