Which category of prohibited substances in sports includes drugs that increase alertness and reduce fatigue?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. Stimulants.
Stimulants are a category of prohibited substances that directly act on the central nervous system to speed up bodily processes. In sports, athletes use them to increase alertness, improve concentration, and reduce fatigue by delaying the onset of tiredness. Common examples include amphetamines and cocaine. However, their use is strictly banned by the World Anti-Doping Agency (WADA) because they provide an unfair competitive advantage and pose serious health risks, such as heart palpitations and increased blood pressure.
