VCE PE Fatigue and Recovery

The most likely cause of fatigue in a 100m sprint is

• Depletion of fuels

• Depletion of fuels PC stores

• Depletion of fuels glycogen stores

• Accumulation of Lactic Acid

Which of the following is not a by-product of the aerobic energy system?

• Water

• Pyruvate

• Carbon Dioxide

• Heat

H+ stands for

• Hydrogen

• Hydrogen Dioxide

• Hydrogen Ions

• Hydrogen Oxide

Which of the following athletes is most likely to accumulate H+ ions during their activity?

• 100m freestyle swimmer

• Tour De France Cyclist

• Lawn Bowler

• Discuss Thrower

The factors that determine the oxygen deficit are:

• PC store levels

• Glycogen stores

• Temperature of the environment

• Intensity, Duration and Type of activity

Which of the following is a fatigue causing by-product?

• Inorganic Phosphates

• H2O

• CO2

• Heat

How long does the stored ATP last when performing maximal intensity exercise?

• 1-2 seconds

• 5-8 seconds

• 8-10 seconds

• 10-30 seconds

Stores of PC are depleted roughly after:

• 1-2 seconds

• 5-8 seconds

• 8-10 seconds

• 10-30 seconds

Hitting the wall refers to:

• Depletion of glycogen stores and utilising Free Fatty acids as the main fuel source

• Depletion of glycogen stores and utilising Amino acids as the main fuel source

• Depletion of PC stores and utilising Amino acids as the main fuel source

• Depletion of Free Fatty Acid stores and utilising glycogen as the main fuel source

The most likely cause of fatigue for a 400m runner is:

• Glycogen depletion

• PC depletion

• Accumulation lactic acid

• Accumulation of plasma
