Which type of exercise is characterized by continuous, low-intensity activity lasting up to an hour or more?

The correct answer is characterized as aerobic exercise, which refers to a form of physical activity that is sustained over a longer period and relies primarily on the body’s aerobic energy-producing processes. During aerobic exercise, the body utilizes oxygen to convert carbohydrates and fats into energy, enabling individuals to perform activities that increase heart and lung endurance.

This type of exercise is typically low in intensity, making it possible to maintain for extended durations, often up to an hour or longer. Common examples include activities like jogging, swimming, cycling, and brisk walking, where participants can carry on a conversation without becoming overly breathless, further emphasizing the low-intensity nature of aerobic workouts.

In contrast, anaerobic exercise involves high-intensity activities that are performed in short bursts and do not rely on oxygen for energy production, leading to quicker fatigue. Types like weightlifting or sprinting are great examples. Isometric exercises are characterized by static strength training without changing the length of the muscle, while dynamic exercises involve movement that may vary in intensity but are not necessarily sustained over long periods.
