An athlete is using creatine monohydrate supplementation. Under current WADA regulations, creatine is classified as:
Answer: A permitted supplement not on the prohibited list
Creatine is not prohibited by WADA and is freely available as a dietary supplement, though product contamination remains a concern.
Which of the following is a primary concern when an athlete combines alcohol with acetaminophen (Tylenol)?
Answer: Potential for severe hepatotoxicity
Both alcohol and acetaminophen are metabolized hepatically; combined use increases toxic metabolite production and risk of liver damage.
Which pharmacokinetic process is primarily responsible for converting lipid-soluble drugs into more water-soluble metabolites for excretion?
Answer: Metabolism (biotransformation)
Metabolism, primarily occurring in the liver, chemically transforms drugs into polar, water-soluble metabolites that can be excreted.
An athlete taking erythropoietin (EPO) for performance enhancement is primarily seeking to improve which physiological parameter?
Answer: Aerobic capacity by increasing red blood cell production
EPO stimulates red blood cell production, increasing oxygen-carrying capacity and improving VO2max in endurance events.
Which of the following best describes the pharmacological concept of a 'therapeutic window'?
Answer: The range between a drug's minimum effective concentration and its minimum toxic concentration
The therapeutic window is the concentration range where a drug provides therapeutic effect without causing toxicity.
A high school athlete's parent requests information about melatonin use for sleep disruption during travel. Which statement is most accurate regarding melatonin?
Answer: Melatonin is an endogenous hormone available OTC and not prohibited by WADA
Melatonin is an endogenous hormone sold OTC in the U.S. and is not on WADA's prohibited list, making it permissible for athletes.
An athlete reports chronic use of oral contraceptives. Which nutritional deficiency has the strongest evidence of association with long-term oral contraceptive use?
Answer: Riboflavin (B2) and Vitamin B6
Long-term oral contraceptive use is associated with depletion of several B vitamins, particularly riboflavin and B6, due to altered metabolism.
