Drug-Taking Behavior in Sports The use of performance-enhancing (ergogenic) drugs in athletic competition has a long history, dating from the original Olympic Games in ancient Greece. In the modern era, the principal type of performance-enhancing drugs has been anabolic steroids.

Drug-Taking Behavior in Sports This latter group typically takes steroids in enormous quantities and administers them in a largely unsupervised fashion. Recently, great concerns have been raised about the use of anabolic steroids, as well as other performance- enhancing drugs, in major league baseball.

For men, the effects include lower sperm count, enlargement of the breasts, atrophy of the testicles, baldness, and severe acne. For women, masculinizing changes occur, only some of which are reversible when steroids are withdrawn.

Patterns of Anabolic Steroid Abuse Since 1990, anabolic steroids have been classified as Schedule III controlled substances, making their possession and sale without a specific medical prescription illegal. In 2004, steroid precursors were added to the category of Schedule III controlled substances.

Nonsteroid Hormones and Performance-Enhancing Supplements Human growth hormone (hGH) is a nonsteroid hormone that has been used for performance-enhancing purposes. Two dietary supplements, androstenedione and creatine, have been prominent recently as performanceenhancing aids.

Nonmedical Use of Stimulant Medication in Baseball In 2007, an unusually large number of MLB players reported taking stimulant medications for ADHD treatment, raising suspicions that this was an effort to circumvent prohibitions against nonmedical stimulant use.

Current Drug-Testing Procedures and Policies The ultimate goal of drug-testing procedures is to make it impossible to yield either a false-negative or false- positive result. A sensitive test yields few false negatives, and a specific test yields few false positives.
