Aerobic exercise increases the ability of the body to take in oxygen, and transport it to your muscles. Increasing aerobic fitness will lead to an increase in the efficiency of the body to take in and utilize oxygen which is associated with decreased fatigue, improvements in exercise capability and your ability to perform activities of daily living, and decrease mortality risk.

  • Cardiorespiratory endurance is an important aspect of health for a number of reasons:
    • Better cardiorespiratory endurance typically leads to higher levels of routine physical activity as you go about your day-to-day life. This in turn provides additional health benefits.
    • Low levels of cardiorespiratory fitness are associated with higher risk of premature death from all causes, and specifically from cardiovascular disease. Increases in cardiorespiratory fitness are associated with a decreased risk of death from all causes.
    • Aerobic fitness is an important foundation that allows you to engage in activities of daily living with greater ease.
    • Aerobic activities that promote cardiorespiratory endurance also burn a relatively large number of calories and thus help to maintain appropriate body weight.
