Which type of exercise is typically characterized by activities like running or cycling aimed at increasing cardiovascular endurance?

Aerobic exercise is specifically designed to increase cardiovascular endurance. Activities such as running, cycling, swimming, and dancing fall under this category because they involve sustained, rhythmic movements that elevate the heart rate and improve oxygen utilization in the body. This type of exercise enhances overall cardiovascular health by strengthening the heart and lungs, increasing blood flow, and improving endurance over time.

Flexibility training focuses on enhancing the range of motion of joints and muscles rather than increasing cardiovascular endurance. Strength training, on the other hand, is aimed at building muscle mass and strength through resistance exercises, which do not primarily target the cardiovascular system. Plyometrics involve explosive movements designed to improve power and athletic performance, but similarly do not focus on endurance. Thus, aerobic exercise is the correct choice as it directly relates to activities that enhance cardiovascular endurance.
