The terms aerobic fitness and cardio-respiratory fitness mean the same thing

Answer 1

Yes, the terms "aerobic fitness" and "cardio-respiratory fitness" are often used interchangeably and refer to the same concept. Both describe the body's ability to take in, transport, and utilize oxygen during sustained physical activity. This type of fitness is indicative of how well the cardiovascular and respiratory systems work to supply oxygen to muscles during exercise. Improving aerobic or cardio-respiratory fitness is typically achieved through activities such as running, cycling, swimming, and other endurance exercises.
