Compare and contrast aerobic physical activity with anaerobic physical activity.

Answer:

Aerobic activity uses oxygen to fuel sustained movement and typically raises the heart and breathing rates for an extended period, as in jogging or swimming. Anaerobic activity involves short, intense bursts of effort that rely more on energy stored in muscles, as in sprinting or lifting weights. Both improve fitness, but they emphasize endurance and cardiovascular health versus strength and power, respectively.
