13.4 Physiological strategies

Question 1

Describe the use of altitude training to improve performance

Answer 1

• Increases RBC’s via increased release of EPO due to less 02 in the air at altitude.
• Therefore you can work at a higher intensity aerobically for longer therefore increased average speed.

Question 1

Describe the use of hypoxic tents to improve performance

Answer 1

• Simulate high altitude by removing some 02 from air leading to increased RBC’s, thus can work at a higher intensity aerobically for longer.

Question 1

Describe the use of hyperbaric chambers to improve performance

Answer 1

Areas that have higher concentrations of 02 in the air than normal, hence speeding up recovery from fatigue and injury.

Question 1

Describe how sleep can improve performance

Answer 1

• Reduces the production of the stress hormone cortisol, therefore decreases stress, anxiety, increases concentration, memory and general health.
  -Also increases the release of HGH therefore improves muscle growth and repair.

Question 1

Describe how cryotherapy can improve performance

Answer 1

Using ice and cold water causes a reduction in blood flow to the injuries therefore decreased localised swelling, therefore can train and play again sooner.

Question 1

Describe how Thermotherapy can improve performance

Answer 1

Warm water can increase blood flow, therefore increase 02 to muscles which speeds up recovery.

Question 1

Describe how massage and foam rolling can improve performance

Answer 1

It increases blood flow, therefore more 02 to the muscles, therefore faster recovery. Also helps psychologically to relax the mind.
