With different sports doping scandals uncovering, the governing bodies of various sports have started taking measures to curb the menace of doping. In this regard, International Tennis Federation has also decided to take a big step by announcing that all the active players will be using biological passport. In addition to the biological passport, increased out of competition doping tests have also been recommended. Previously very few out of competition dope tests were conducted in tennis. In year 2011, only 21 out of competition blood tests were taken to check the doping which is a very few number. In the same year, cycling governing council UCI had taken at least 3,314 such dope tests.
The decision of increased dope tests and biological passport has come after many active players had called for more measures to curb and detect doping cases in tennis to prevent any case similar to that of Lance Armstrong. The introduction of biological passport will help to detect changes in the blood of athletes against their original blood profile as it contains test results collated at different times. Cycling governing body UCI has already introduced biological passports in 2008.
