CARDIORESPIRATORY ENDUCANCE. HEART / LUNGS / BLOOD AND THE BODY. Cardiorespiratory Endurance. The most important component of physical fitness, and best indicator of overall health. The measure of how efficiently our bodies work: oxygen uptake / distribution and utilization.
HEART / LUNGS / BLOOD AND THE BODY
Low to moderate intensity exercises.
Body requires oxygen to produce energy (ATP).
Walking, jogging, swimming, cycling, etc.
High intensity exercises.
Exercise that doesn’t need oxygen to produce energy.
2-3 minutes of high energy bursts.
100, 200, 400 meter sprints, weight lifting, etc.
Higher maximum oxygen uptake
Increase in oxygen-carrying capacity of the blood.
Decrease in resting heart rate
Increase cardiac output & stroke volume.
Lower heart rate at given workloads.
Increase number & size of mitochondria.
Increase number of functional capillaries.
Increased recovery time.
Decreased blood pressure & blood lipids.
