What is cardiovascular endurance also known as?

Cardiovascular endurance is also known as aerobic fitness because it focuses on the ability of the heart, lungs, and blood vessels to supply oxygen to the muscles during sustained physical activity. This type of endurance is critical for activities that require prolonged effort, such as running, cycling, or swimming, where oxygen is utilized efficiently to fuel the muscles over extended periods.

Aerobic fitness signifies the effectiveness of the cardiovascular and respiratory systems in transporting oxygen to the working muscles, enabling individuals to perform aerobic activities with greater stamina and efficiency. This is why cardiovascular endurance is synonymous with aerobic fitness. The other options refer to different aspects of physical training or fitness; muscular endurance pertains to the muscles' ability to sustain repeated contractions over time, flexibility training focuses on improving the range of motion in joints, and plyometric training involves exercises that produce quick, powerful bursts of movement, primarily to improve speed and power rather than endurance.
