Thesis: Athletes who use any type of biotechnology give themselves an unfair advantage and disrupt the sense of fair play, and they should be banned from competition.

• Athletic achievement nowadays increasingly results from biological and high-tech intervention rather than strictly from hard work.
• There is a difference between the use of state-of-the-art equipment and drugs and the modification of the body itself.
• If the rules that guarantee an even playing field are violated, competitors and spectators alike are deprived of a sound basis of comparison on which to judge athletic effort and accomplishment.
• If we let athletes alter their bodies through biotechnology, we might as well dispense with the human element altogether.
