Define ergogenic aids and give two examples with ethical considerations.

• A. Ergogenic aids are substances or strategies intended to enhance performance; examples include caffeine and bicarbonate; ethical considerations include fairness and safety.
• B. Ergogenic aids are only illegal substances; examples include steroids and diuretics; ethics are not a concern.
• C. Ergogenic aids are training devices; examples include jump ropes and resistance bands; ethics relate to accessibility.
• D. Ergogenic aids are dietary plans; examples include vegan and ketogenic diets; ethics relate to cost.

Answer: (A)

Ergogenic aids are substances or strategies designed to enhance athletic performance. Two commonly cited examples are caffeine and bicarbonate. Caffeine acts as a stimulant that can improve alertness and endurance in many sports, while bicarbonate helps buffer lactic acid in muscles, delaying fatigue during high‑intensity efforts. Both are used legitimately, but they bring ethical considerations: fairness, since access and individual responses can vary, and safety, because improper use or dosing can pose health risks and must align with competition rules. The other options miss the broader scope of what ergogenic aids encompass—legal substances in some cases, or equipment and nutrition strategies that aren’t precisely the same category as substances or strategic approaches used to boost performance.
