Which of the following characteristics apply to aerobic exercise?

Aerobic exercise is characterized by its reliance on oxygen to fuel the body during physical activity, which typically occurs at a lower intensity but over longer durations. This type of exercise encourages the use of fat as a primary energy source, which is efficient for extended periods of activity. Examples include activities such as jogging, cycling, or swimming, where the body has sufficient oxygen to perform the exercise without quickly exhausting its energy reserves.

The emphasis on low intensity allows individuals to maintain the activity over time, making it easier to sustain for longer periods without fatigue. In contrast, higher intensity workouts tend to rely more on carbohydrates for energy and are typically shorter in duration. Understanding these characteristics helps distinguish aerobic exercise from other forms like anaerobic exercise, which involves short bursts of high-intensity effort and relies more on quick energy sources. This distinction is vital for designing effective fitness programs that meet various health and fitness goals.
