GRADE 12 - PE and HEALTH

What is the fuel source for the Anaerobic Glycolysis System?

• PC

• Glycogen

• Glycogen & FFAs

• FFAs

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

• High Intensity (85% MHR)

• At rest

• Sub-maximal intensity (<85% MHR)

• High Intensity (95% MHR)

At what duration does the aerobic energy system become dominant?

• 45 seconds

• 15 seconds

• 75 seconds

• 5 seconds

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

• ATP-PC System

• Aerobic System

• Lactic Acid System

The ATP-PC system is limited by

• production of lactic acid as a by-product

• the need for long chemical reactions

• the ability to re-synthesise ATP quickly

• limited stores of phosphocreatine in the muscles

Which of the following does NOT occur when working at or above the lactate threshold?

• Ventilation rate increases

• Pain levels increase

• Fatigue sets in

• Blood lactate levels decrease

Which one of these is considered the "good fats" that we get from foods?

• Unsaturated Fat

• Saturated

• Trans Fat

• Carbs

The anaerobic glycolysis system

• operates without oxygen

• is used for high intensity exercise

• provides energy for about 10 seconds to 90 seconds

• all of the above

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

• Carbohydrates

• Fats

• Proteins

• all of the above

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

• intensity of the activity

• duration of the activity

• Both 1st and the 2nd choice

• none of the above
