Cardiorespiratory endurance is the body's ability to carry out strenuous tasks such as exercise while maintaining adequate oxygen supply to the muscle and organ cells. This means that a person with high cardiorespiratory endurance will be able to carry out strenuous tasks more easily, while someone with less endurance is more likely to fail.
More importantly, a high endurance of the cardiovascular and respiratory systems helps prevent heart disease in individuals, which improves a person's overall health.
