Which of the following describes exercise that requires oxygen?

The term that describes exercise requiring oxygen is aerobic. Aerobic exercise involves activities that can be sustained over a prolonged period and rely on the body’s ability to supply adequate oxygen to the muscles. This type of exercise improves cardiovascular fitness, enhances the ability of the heart and lungs to work efficiently, and typically includes activities such as running, cycling, swimming, and dancing.

In contrast, anaerobic exercise refers to short bursts of high-intensity activity where the demand for oxygen exceeds the oxygen supply available to the muscles, making it rely on energy sources stored within the muscles. Examples include sprinting and weightlifting. Immediate exercise generally focuses on quick reactions and does not characterize the reliance on oxygen for sustained activity. Responsive exercise may not specifically pertain to the physiological demands regarding oxygen usage in the context of sustained physical activity.

Thus, aerobic is the terminology that accurately encapsulates exercise demanding oxygen for energy production over extended periods.
