Answer:
The 12 Minute Run fitness test was developed by Dr. Ken Cooper in 1968 as an easy way to measure aerobic fitness and provide an estimate of VO2 max for military personnel. This simple test is still used today as a field test for determining aerobic fitness.
Dr. Cooper found that there is a very high correlation between the distance someone can run (or walk) in 12 minutes and their VO2 max value, which measure the efficiency with which someone can use oxygen while exercising.
This test is still one of the basic fitness tests used by the military, as well as many coaches and trainers to determine cardiovascular fitness and track fitness over time. This simple test also allows you to compare your cardiovascular endurance with others of your age and gender.
What is Cardiovascular Endurance?
In sports, cardiovascular endurance refers to an athlete's ability to sustain prolonged exercise for minutes, hours, or even days. Endurance testing is a way to measure the efficiency of an athlete's circulatory system and respiratory system in supplying oxygen to the working muscles and support sustained physical activity.
When we talk about endurance, we generally refer to aerobic endurance. Aerobic exercise requires oxygen to help supply the energy needed for exercise. The objective of endurance training, then, is to develop and improve the body systems that produce and deliver the energy needed to meet the demands of prolonged activity.
