1.1 Cardiovascular Endurance
β Definition & Mechanism: The capacity of the cardiorespiratory system (heart, lungs, blood vessels) to deliver oxygen-rich blood to skeletal muscles during sustained exertion. Involves increased stroke volume and capillarisation in trained individuals.
β Physiological Adaptations: Enhanced cardiac output, increased mitochondrial density, improved VOβ max, lower resting heart rate.
β Advanced Assessment Protocols:
β Laboratory Test: Graded treadmill test with gas analysis to measure VOβ max directly.
β Field Test Variation: Cooper 1.5-mile run for school settings, with normative data tables by age and sex.
β Training Example: Long slow distance (LSD) runs at 65β75% of HRmax for 30β60 minutes, twice weekly, complemented by interval training (4 Γ 4βminute at 85β90% HRmax with 2-minute recovery).
Detailed Explanation
Cardiovascular endurance refers to how well your heart and lungs function when exercising or doing any kind of sustained physical activity. It indicates how efficiently your body can deliver oxygen to your muscles. Improved cardiovascular endurance can lead to a healthier heart and lungs. This section also describes methods to assess this endurance, such as treadmill tests and running a specific distance. Training for endurance often involves long, slow runs and can include interval training for better performance.
Examples & Analogies
Imagine your heart as a pump in a swimming pool. The more effectively it pumps water (or oxygen, in this case) to the swimmers (your muscles), the longer they can swim without tiring. Training for cardiovascular endurance is like increasing the pump's capacity to push more water efficiently, allowing swimmers to perform better.
