21 Adaptations to body systems - High Altitude

Which adaptation occurs in the body to increase oxygen transport when exposed to high altitude?

• Decreased red blood cell production

• Reduced capillarisation

• Decreased haemoglobin concentration

• Increased red blood cell production

What happens to haemoglobin concentration in response to high altitude exposure?

• It decreases

• It remains unchanged

• It increases

• It fluctuates randomly

Which of the following best describes capillarisation as an adaptation to high altitude?

• Decrease in the number of capillaries

• Increase in the number of capillaries

• No change in capillary density

• Capillaries become less efficient

How do mitochondria adapt to high altitude conditions?

• Their number decreases

• Their efficiency decreases

• Their number increases

• They stop functioning

What is the role of oxidative enzymes in adaptation to high altitude?

• They decrease in activity

• They increase in activity

• They are unaffected

• They are replaced by anaerobic enzymes

Which type of sport performance is most positively impacted by high altitude adaptations?

• Anaerobic performance

• Flexibility performance

• Strength performance

• Aerobic performance

How does high altitude adaptation generally affect anaerobic performance?

• It significantly improves it

• It has little or no positive effect

• It always decreases it

• It doubles anaerobic capacity

Which method is used to simulate high altitude conditions at sea level for athletes?

• Hyperbaric chambers

• Cryotherapy chambers

• Hypoxic chambers

• Sauna rooms

What does the 'sleep high, train low' strategy involve?

• Sleeping at low altitude and training at high altitude

• Sleeping and training at sea level

• Sleeping at high altitude and training at low altitude

• Only training at high altitude

Why might athletes use hypoxic chambers to sleep or train?

• To decrease their red blood cell count

• To mimic the effects of high altitude and promote physiological adaptations

• To increase muscle mass directly

• To improve flexibility
