Cardiorespiratory endurance is a component of fitness and refers to the body's ability to supply and use oxygen and involves the cardiovascular and respiratory systems. These systems include the heart, blood vessels, lungs, diaphragm, and air passages, which transport oxygen, nutrients, and other substances throughout the body. The types of activities that impact cardiorespiratory endurance are those that involve rhythmic use of large muscle groups for an extended period of time and are generally referred to as cardio, aerobic, or endurance exercise. Cardiorespiratory endurance activities can be light-, moderate-, or vigorous-intensity and each has benefits.
