The biggest story in tennis this week is not Rafael Nadal making his comeback on hard courts or Novak Djokovic going for the IW-KB double, but the new Biological Testing Policy that was placed into effect. Here's the article about it from the Associated Press:Tennis bodies adopt biological passport and increased blood testing in anti-doping drivePublished March 07, 2013Associated PressLONDON – Tennis has agreed to adopt the biological passport program and to increase blood testing as part of a new anti-doping drive.The move was announced Thursday by the International Tennis Federation, which said the measures will go into effect this year on both the men's and women's tours.The biological passport tracks an athlete's blood profile over time for any changes that could indicate doping. The system is already applied in track and field and cycling.The ITF says the project will mean an increase in the number of blood tests carried out each year, as well as an overall increase in out-of-competition controls.ITF President Francesco Ricci Bitti says implementation of the passport program "provides us with a great tool in the fight against doping in our sport."Read more: key is that there will be more blood tests of players and out-of-competition tests. It was very revealing when Djokovic said at the Aussie Open that he was not being tested very much out of competition. it was reported that: "The ITF and WADA conducted only 21 out-of-competition blood tests – used to detect growth hormone, EPO, transfusions and other blood-doping substances – in tennis in 2011. The vast majority of tests in tennis in 2011 – 2,019 of a total of 2,150 – were urine."The biological testing sets a baseline for what a player's testosterone levels are and if they spike for any reason, even if the testers can't tell why it spiked, they know something smells in Denmark. So this is a positive because when I was in Delray talking to the ATP rep, he said the biological testing is what the pro cycling circuit is doing and track and field, too. Now maybe the ITF will also be more forthright with who their testing, how many times, and what the results are as well. But I doubt it because the ITF has always been clandestine on these matters. But I say, Open It Up, let's make this sport transparent. Even Rafa, who has been critical of being over-tested said it should be made public who is being tested and how frequently.“The important thing is that those who are cheating, pay for their cheating,” Nadal said. “With Armstrong the image of sport has been damaged, especially in the case of cycling. The important thing is for sport to clean up its image, that the controls are made public.”
