Which of the following is an example of an aerobic activity?

Long-distance cycling is an excellent example of aerobic activity because it primarily relies on continued and rhythmic movement that enhances the efficiency of the cardiovascular system. Aerobic activities are characterized by their ability to increase heart rate and improve oxygen consumption over extended durations. During long-distance cycling, participants maintain a moderate level of intensity, allowing for sustained effort that strengthens the heart, lungs, and overall endurance.

In contrast, weightlifting, sprinting, and powerlifting tend to prioritize short bursts of high-intensity effort, focusing more on strength and power rather than prolonged aerobic endurance. These activities typically rely on anaerobic energy systems, which do not utilize oxygen in the same way that aerobic exercises do. Thus, long-distance cycling stands out as a quintessential example of a workout that builds aerobic capacity and endurance, making it the correct choice.
