The capacity of the cardiovascular and respiratory systems to deliver oxygen to the working muscles for sustained periods of energy production.
The ability of the heart, lungs, and blood vessels to mobilize the body’s energy and sustain movement over an extended period of time, cardiorespiratory efficiency.
Cardiorespiratory endurance (CRE) is the ability to deliver essential nutrients, especially oxygen, to the working muscles of the body and remove waste products during prolonged physical exertion. It involves efficient functioning of the heart, blood vessels, and lungs.
The ability of the heart, blood vessels, and lungs to distribute nutrients and oxygen and to remove wastes.
The ability to perform large-muscle movements over a sustained period of time; the ability of the circulatory and respiratory systems to deliver fuel, especially oxygen, to the muscles during continuous exercise.
