Which of these are characteristics of aerobic activity?

• A. An activity that is rhythmic in nature.
• B. It can be sustained for more than 10 mins.
• C. All of these are correct.
• D. It uses large muscle groups

Answer: (C)

Aerobic activity is defined by sustained, oxygen-using exercise that keeps the heart rate elevated over a period of time. The movements are rhythmic and continuous, typically involving large muscle groups like the legs or arms, which helps keep the activity going smoothly. Because it relies on oxygen and can be continued for extended periods, it can be sustained for more than about 10 minutes. Each of these characteristics describes aerobic exercise, so all of these statements are correct. Examples include brisk walking, cycling, and swimming at a moderate pace.
