Step-by-step explanation:
Cardiorespiratory endurance, also known as aerobic fitness, is the ability of the heart, lungs, and circulatory system to deliver oxygen and nutrients to the body's tissues during prolonged physical activity. It is a measure of how efficiently the body can use oxygen to produce energy for muscular activity over an extended period of time.
Cardiorespiratory endurance is typically assessed through exercise tests that measure an individual's maximum oxygen uptake (VO2 max), which represents the highest amount of oxygen that a person can consume during exercise. Higher VO2 max values are associated with better cardiorespiratory fitness and can indicate a lower risk for cardiovascular disease, as well as improved overall health and fitness.
