Doping refers to the use of banned substances or methods to enhance athletic performance. It undermines the principles of fair competition and can pose serious health risks to athletes. Common substances include steroids and stimulants, which can provide an unfair advantage in various sports. The fight against doping is led by organizations like the World Anti-Doping Agency (WADA), which establishes regulations and conducts testing to ensure athletes compete fairly. Education and awareness are crucial in promoting clean sports and protecting the integrity of athletic competitions.
