Cardiovascular EnduranceCardiovascular endurance is the ability of the heart, lungs and blood vessels to deliver oxygen to working muscles and tissues, as well as the ability of those muscles and

tissues to utilize that oxygen over an extended period of time with moderate intensity.

What happens to your body during cardiovascular endurance or aerobic training?

• The heart pumps faster and pumps more blood.

• Lungs increase volume of air inhaled and exhaled.

• Muscles contract at a greater speed.

• Body temperature rises and the body sweats.

Benefits of cardiovascular endurance training.

• The heart becomes more efficient • Blood volume, red blood cells and hemoglobin increases • Decreases resting blood pressure • Arteries grow larger • Diaphragm grows stronger • Lungs become more expandable increasing in volume • Decreases body fat • Increases energy level • Recovery after exercise becomes quicker • Reduces risk of heart disease and other health

conditions. • Reduces the risk of an early death.

Factors that affect your cardiovascular endurance.

• 1. The ability of the respiratory system to take air into the body and the efficiency with which the lungs supply oxygen to the blood. Endurance is reduced if your breathing is inefficient or if the lungs are not working well.

• 2. The ability of the blood to carry oxygen. This can be reduced if you are ill, have a poor diet or train too hard.

• 3. The ability of your heart to pump blood around your body.

• 4. The efficiency of the circulatory system that takes blood to your muscles and then returns it to your heart.

• 5. The ability of your muscles to extract oxygen from your blood.

• 6. Heredity influences your level of Cardio Vascular Endurance
