Question

the track coach notices that his star runner is running quicker than ever before, but quickly gets tired and shows evidence of depression after the race. the coach should suspect that the runner might be taking ______. a. growth hormones b. amphetamines c. protein supplements d. creatine please select the best answer from the choices provided. a b c d

Explanation:

To solve this, we analyze each option:

• Option A: Growth hormones are for growth/development, not for quick energy followed by depression/tiredness. Eliminate A.
• Option B: Amphetamines are stimulants. They can increase speed (due to stimulation) but lead to crashes (tiredness, depression) as the effect wears off. This matches the runner's symptoms.
• Option C: Protein supplements help with muscle repair/growth, not causing quick tiredness or depression. Eliminate C.
• Option D: Creatine helps with short - term energy in high - intensity exercise, but doesn't typically cause depression after use. Eliminate D.

Answer:

B. amphetamines
