A-LEVEL PE (OCR): PAPER 3 - Ethics and Deviance in Sport

These flashcards describe key performance-enhancing methods, including blood doping—a technique used to increase red blood cell count and oxygen-carrying capacity, commonly by endurance athletes—and anabolic steroids, which boost strength, aggression, and training capacity. They highlight how these methods aim to enhance performance, often through artificial physiological manipulation.
