Final answer:
Aerobic exercise is physical activity with slow, short, and sustained movements that focuses on improving cardiovascular endurance by utilizing slow-twitch muscle fibers. It is low-intensity and long-duration as opposed to anaerobic exercise. Examples include cycling, swimming, and brisk walking.
Step-by-step explanation:
Exercise done with slow, short, and sustained movement is typically referred to as aerobic exercise. This form of physical activity involves using muscles at a level well below their maximum contraction strength for a relatively long period of time, leading to the consumption of a large amount of oxygen. The primary objective of aerobic exercise is to increase cardiovascular endurance, although muscle toning can also be a beneficial outcome.
Aerobic exercise integrates a high percentage of slow-twitch muscle fibers, which are mainly responsible for aerobic activities such as long-distance running. Examples of aerobic exercise include cycling, swimming, brisk walking, jumping rope, rowing, hiking, and tennis. Unlike anaerobic exercise, which is high intensity and short duration, aerobic exercises are designed to be low-intensity enough that they do not generate significant lactate, allowing all carbohydrate to be turned into energy aerobically.
