The Energy Systems

The ATP-PC system is utilised during what exercise intensity?

• Sub-maximal intensity (<85% MHR)

• High Intensity (95% MHR)

• High Intensity (85% MHR)

• At rest

At what duration does the aerobic energy system become dominant?

• 30 seconds

• 1 minute

• 2 minutes

• 3 minutes

An elite 3000m runner would predominantly use which energy system during a race?

• ATP-PC Energy System

• Anaerobic Glycolysis Energy System

• Aerobic Energy System

 

Which would be the dominant energy system in this physical activity?

• ATP-PC System

• Lactic Acid System

• Aerobic System

The anaerobic glycolysis system

•  

  operates without oxygen

• is used for moderate - high intensity exercise

• provides energy for about 10 seconds to 90 seconds

• all of the above

• none of the above

For athletic events such as javelin and discus, the predominant energy system used is

• aerobic system

• anaerobic glycolysis system

• ATP-PC system

The substance that accumulates in the muscle during anaerobic glycolysis is known as:

• phosphate creatine

• lactic acid

• triglyceride

• ATP

Which of the following fuels can be used to produce energy?

• Carbohydrates

• Proteins

• all of the above

• Fats

• none of the above

The speed of ATP production when the aerobic energy system is predominant is:

• very fast

• fast

• slow

Our breathing rate increases and you start to breathe heavily, this happens because

• More blood gets circulated around the body

• We have started to perform a physical activity

• To break down Lactic Acid and replenish energy supplies.

• Our muscles need more oxygen so you breathe deeper and quicker so a supply of oxygen can get to the muscles.
