Explosive movements and plyometrics predominantly use the ATP-PC energy system. Here's why:

1. The ATP-PC system, also known as the phosphagen system, provides immediate energy for short, intense bursts of exercise, such as a 100-meter sprint or a maximal weight lift. This is because it uses stored ATP (adenosine triphosphate) and PC (phosphocreatine) in the muscles, which can be broken down quickly to produce energy.

2. Plyometrics and explosive movements are typically high-intensity, short-duration exercises. They require a rapid, powerful movement, which the ATP-PC system is perfectly designed to handle.

3. The glycolytic energy system and the aerobic energy system are used for longer durations of exercise. The glycolytic system is used for moderate to high intensity exercises lasting for a few minutes, while the aerobic system is used for low to moderate intensity exercises lasting for several minutes to hours.

4. The basal metabolic system is not an energy system used during exercise. It refers to the rate at which your body uses energy while at rest to maintain vital functions such as breathing, circulating blood, and regulating body temperature.

So, the ATP-PC energy system is the primary energy system used during explosive movements and plyometrics.
