Questions and Answers

How does altitude training primarily benefit athletes?

  • By decreasing muscle mass and improving flexibility.
  • By lowering the resting heart rate and blood pressure.
  • By reducing the need for dietary supplements and enhancing hydration.
  • By increasing red blood cell production, enhancing oxygen delivery. (correct)

What key physiological adaptation occurs in athletes due to consistent training at high altitudes?

  • Decreased lung capacity and reduced respiratory rate.
  • Enhanced anaerobic capacity and lactic acid tolerance.
  • Improved oxygen extraction efficiency and increased mitochondria density. (correct)
  • Increased bone density and reduced joint stress.

Which of the following is a crucial consideration when implementing altitude training for athletes?

  • Immediate increase in training intensity upon arrival at altitude.
  • Monitoring iron levels and maintaining adequate hydration. (correct)
  • Focusing exclusively on high-intensity workouts at altitude.
  • Ignoring signs of altitude sickness to maximize training benefits.

High performance

High performance involves reaching optimal functioning at every stage. It's sustained throughout preparation and competition.

Fine-tuning

This involves continually making subtle adjustments and changes to refine and improve performance.

Study Notes

  • Marfan Syndrome is a genetic disorder affecting the body's connective tissue.
  • Connective tissue provides strength and support to tendons, ligaments, blood vessel walls, cartilage, heart valves, and other body parts.
  • Both men and women of all races and ethnic backgrounds can get the disorder.
  • Marfan Syndrome is caused by a defect, or mutation, in the gene that controls the production of fibrillin-1.
  • Fibrillin-1 is a protein essential for the formation of connective tissue.
  • It is estimated that at least 1 in 5,000 people in the United States has Marfan syndrome.
  • About 3 out of 4 people who have Marfan syndrome inherit it from a parent with the disorder.
  • However, some cases result from a new genetic mutation.
  • This spontaneous mutation means that person is the first in the family to have it.
