Energy system interplay refers to

• All three energy systems working together

• One energy system providing more energy than the other two systems at any point in time

• Three energy systems working together and one kicking in as the others drop off

• The PC system providing most energy first, then the aerobic system then the aerobic system

When using the anaerobic glycolysis energy system

• Most of the ATP is produced from fats

• Twice as much ATP is released when compared to the ATP-PC system

• Activity will only be possible for another 45 seconds

• LIP is being trained

In a marathon, two competitors enter the stadium together and the final sprint will determine the winner. Which energy system is providing the most ATP in the final sprint to the finish line?

• The ATP-PC energy system

• The alactacid system

• The aerobic energy system

• The anaerobic glycolysis system

Carbohydrates require

• Less oxygen than fats to break down

• More time than protein to break down

• More oxygen than protein to break down

• More time than fats to break down

Improving the capacity of the anaerobic glycolysis system will also improve

• Lactic acid removal

• Lactate shuttling

• LIP

• Lactate tolerance

When contrasting the energy systems, the ATP-PC system has

• The fastest rate of production

• The largest capacity

• A slower rate than the anaerobic glycolysis system

• A larger capacity than the aerobic energy system

A 30 minute jog at about 50% max HR would predominantly use

• Triglycerides

• Free fatty acids

• Carbohydrates

• Proteins

When an athlete starts to jog for part of their warm up, the ATP-PC system

• Is depleted at a faster rate than at higher intensities

• Calls upon less carbohydrates than at higher intensities

• Provides ATP for longer than at higher intensities

• Splits ATP at a faster rate than at higher intensities

An acute response to exercise is

• A response that lasts beyond the exercise period

• A response that lasts for the duration of the exercise period

• A response that lasts for the duration of the exercise and the recovery period

• A long-term physiological response

When exercise commences, the demand for oxygen and energy substrates

• Increase

• Decrease

• Stay the same

• Remain at resting levels
