The term "performance-enhancing drugs" (PEDs) in sports refers to substances that athletes illegally use to improve their performance unfairly. These drugs can include steroids, stimulants, and other banned substances that enhance attributes like strength, endurance, and recovery. PED use raises serious ethical concerns, as it undermines the principles of fair competition and can harm an athlete's health. Regulatory bodies in sports enforce strict policies and testing to deter the use of these substances, aiming to protect the integrity of competition and athlete welfare.
