|
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 anaerobic glycolysis system and then the aerobic energy system.

Detailed explanation-1: -Energy system interplay simply refers to the energy systems working together, but at different rates, to supply the ATP required for an activity. When you look at the table above you will notice that there is a trade-off between Power and Yield for each of the energy systems.
Detailed explanation-2: -Energy systems refer to the specific mechanisms in which energy is produced and used by your body. Like most mammals, you generate energy via three systems: phosphagen (ATP-PC), glycolytic, and oxidative (see figure 2.1). All three energy systems are engaged during all forms of physical activity.
Detailed explanation-3: -To sustain muscle contraction, ATP needs to be regenerated at a rate complementary to ATP demand. Three energy systems function to replenish ATP in muscle: (1) Phosphagen, (2) Glycolytic, and (3) Mitochondrial Respiration.
