10 PED Energy Systems

During rest, energy is produced mostly

• aerobically with oxygen

• aerobically without oxygen

• anaerobically with oxygen

• anaerobically without oxygen

The ATP-PC energy system

• utilises carbohydrates

• needs the presence of oxygen

• is used for endurance type activities

• provides energy for up to about 10 secs of high intensity work

The anaerobic glycolysis system

• operates without oxygen

• provides energy for about 10 seconds to 90 seconds

• is used for high intensity exercise

• 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

• triglyceride

• lactic acid

• ATP

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

• Carbohydrates

• Proteins

• Fats

• all of the above

• none of the above

The fuel source for anaerobic glycolysis is:

• Carbohydrates

• Proteins

• Fats

• all of the above

• none of the above

The energy system used for a particular activity will depend on the:

• intensity of the activity

• duration of the activity

• both of the above

• none of the above

The steady state indicates that the:

• aerobic system is being used

• anaerobic glycolysis system is being used

• ATP-PC system is being used

• anaerobic energy system is being used

EPOC stands for

• Excess Pre-exercise Oxygen Consumption

• Excess Post-exercise Oxygen Consumption

• Energy Producing Oxygen Consumption

• Energy Pathways Oxygen Consumption
