Final answer:
The word 'aerobic' actually means 'with oxygen' and refers to exercises that involve sustained physical activity to improve cardiovascular endurance, unlike anaerobic exercise, which means 'without oxygen' and includes short, intense bursts of activity.
Step-by-step explanation:
The statement that the word "aerobic" means without oxygen is false. Aerobic exercise is a type of physical activity that relies on the presence of oxygen to fuel the energy demands of the body during sustained activity. The term "aerobic" literally means "with oxygen". Examples of aerobic exercise include activities like jogging, cycling, swimming, and walking, which involve sustained movement that increases cardiovascular endurance. On the other hand, anaerobic exercise, such as weightlifting and sprinting, is characterized by short bursts of intense activity where the body's demand for oxygen exceeds the supply, leading to the production of energy through processes that do not require oxygen.
