What is the height (in metres) that can be classed as high altitude?

• 2500

• 1500

• 2400

• 3000

What is anaerobic power?

• The peak volume of oxygen consumed and utilised in one minute .

• The exercise intensity at which lactic acid starts to build up in the body faster than it can be removed.

• The maximal force that a muscle can generate in one single effort.

• The maximal power developed in maximal short-term exercise.

Thermoreceptors detect a change in....

• pH, carbon dioxide and oxygen

• temperature

• blood pressure

• muscle length and movement.

Why is an increase in mitochondria a beneficial long-term adaptation?

• Increases the blood supply.

• Increases the storage of oxygen.

• Increases aerobic energy production. This will delay fatigue.

Why can the release of Oestrogen be beneficial?

• Raises the level of nutrients in the blood.

• Increases protein synthesis.

• Increases heart rate and vasodilation.

• Helps with the regulation of bone remodelling. Can help prevents osteoporosis.

What happens during inhalation?

• The diaphragm contracts, lifting the ribcage up and out. The thoracic cavity size increases, thus air rushes in.

• The diaphragm relaxes, as the ribs go back down and in. The thoracic cavity size decreases.

• The external intercostals relax. Air is pushed into the lungs.

What are the adaptations to training in altitude conditions for long periods of time?

What is summation?

• To fire a lot of impulses in targeted muscles all at once.

• When nervous inhibition decreases as a result of long-term training.

• The breakdown of muscle tissue.

What is VO2 Max

• The exercise intensity where lactate accumulates faster than it can be removed

• The amount of oxygen stored in the muscle.

• The volume of oxygen consumed and utilised in one minute.

• The capacity to perform repeated muscle contractions, or to sustain a contraction over time.
