Cardiovascular Endurance
Cardiovascular 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
