Test your knowledge of the science behind performance-enhancing drugs.


Questions and Answers
  • 1. 

    Which drug increases the number of red blood cells thereby increasing the transport of oxygen in the body?

    • A.

      EPO (Erythropoietin)

    • B.

      Clenbuterol

    • C.

      Human growth hormone

  • 2. 

    This is the structural diagram of which drug that increases heart rate and blood flow to muscle by activating noradrenaline receptors in the lungs?

    • A.

      EPO (Erythropoietin)

    • B.

      Clenbuterol

    • C.

      Human growth hormone

    Correct Answer
    B. Clenbuterol
    Explanation
    Clenbuterol is the correct answer because it is a drug that increases heart rate and blood flow to muscles by activating noradrenaline receptors in the lungs. EPO (Erythropoietin) and Human growth hormone do not have this specific mechanism of action.

    Rate this question:

  • 3. 

    Caffeine in large doses was prohibited by the World Anti-Doping Agency until what year?

    • A.

    Caffeine was removed from the Prohibited List in 2004. Its use in sport is not currently prohibited.

    Rate this question:

  • 4. 

    Which of these foods has recently been shown to make runners use oxygen more efficiently?

    • A.

      Dill pickles

    • B.

      Grapefruit juice

    • C.

      Bacon

    • D.

      Beetroot juice

    Correct Answer
    D. Beetroot juice
    Explanation
    Like nitrate pills, beetroot juice has been shown to make athletes use oxygen more efficiently.

    Rate this question:

  • 5. 

    Which of these natural substances is required by the human body, but banned for use as a supplement by all sporting bodies?

    • A.

      Blood

    • B.

      Milk

    • C.

      Fiber

    • D.

      Vitamin D

    Correct Answer
    A. Blood
    Explanation
    Blood doping (receiving infusions of your own or another's red blood cells) enhances the body's oxygen delivery mechanism. The World Anti-Doping Agency (WADA) does not allow transfusions except in the case of medical emergencies.

    Rate this question:

  • 6. 

    Which of the following does not increase the efficiency of oxygen delivery in the blood?

    • A.

      EPO (Erythropoietin)

    • B.

      Training at high altitude

    • C.

      Human growth hormone

    • D.

      Spending time in a low oxygen tent

    Correct Answer
    C. Human growth hormone
    Explanation
    Human growth hormone does not increase the efficiency of oxygen delivery in the blood. EPO (Erythropoietin) is a hormone that stimulates the production of red blood cells, which carry oxygen. Training at high altitude increases the production of red blood cells and improves the body's ability to utilize oxygen. Spending time in a low oxygen tent also stimulates the production of red blood cells. However, human growth hormone primarily promotes growth and development, but it does not directly affect oxygen delivery in the blood.
