Final answer:
The immediate energy system, nonoxidative energy system, and oxidative energy system are different ways the body produces energy for different types of physical activities.
Step-by-step explanation:
Immediate Energy System
The immediate energy system, also known as the ATP-PC system, provides energy for short bursts of high-intensity activities. It relies on stored ATP (adenosine triphosphate) and phosphocreatine stored in the muscles. Examples of activities that use the immediate energy system include sprinting, weightlifting, and jumping.
Nonoxidative Energy System
The nonoxidative energy system, also called the anaerobic glycolysis system, provides energy for medium-intensity activities. It involves the breakdown of glucose or glycogen without the need for oxygen. This system can provide energy for activities such as running a mile or swimming a lap at a faster pace.
Oxidative Energy System
The oxidative energy system, also known as aerobic metabolism, provides energy for long-duration, low-intensity activities. It uses oxygen to break down carbohydrates, fats, and sometimes proteins to produce ATP. Examples of activities that primarily use the oxidative energy system include long-distance running, cycling, and hiking.
