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
Correct Answer
A. EPO (Erythropoietin)

Explanation
Athletes, particularly distance runners and cyclists, have used EPO to improve their endurance.

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.

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

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.

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.
