Cardiorespiratory Endurance
Cardiorespiratory endurance is the most important component of health related physical fitness. Aerobic exercise is very crucial in preventing cardiovascular disease. A poorly conditioned heart has to pump more often to keep a person alive and is subject to more wear and tear than someone who has a well-conditioned heart. With today's society being active and physical is not part of daily life, sedentary living is a way of life due to technology. Cardiorespiratory endurance is defined as the ability of the lungs, heart, and blood vessels to deliver adequate amounts of oxygen to the cells to meet the demands of prolonged physical activity. When someone exercises regularly with aerobic exercise their heart does not need to work as hard as their body utilizes oxygen as energy better than someone that does not do aerobic exercise. Anaerobic exercise is so high that oxygen cannot be delivered and utilized to produce energy.
Benefits:
Aerobic exercise programs have a number of beneficial physiological benefits, they are; a higher maximal oxygen uptake (VO2max), an increase in the oxygen-carrying capacity of the blood, a decrease in resting heart rate and an increase in cardiac muscle strength, a lower heart rate at given workloads, an increase in the number, size, and capacity of mitochondria. More benefits would include an increase in the number of functional capillaries, ability to recover rapidly, lower blood pressure and blood lipid levels, and an increase in fat burning enzymes.

assessing Cardiorespiratory exercise:
There are different ways to do assessments of cardiorespiratory endurance. The most significant way to do that is by testing the VO2max. Examples would include 1.5 mile run test, one mile walk test, step test, and astrand-rhyming test. After going through the procedures to figure out your VO2max, you can then assess of what your next goals are to improve your cardiorespiratory fitness. The rate of how quickly you progress through an exercise program depends on your house status, exercise tolerance, and exercise program goals. At the beginning only three week training sessions of 15 to 20 minutes are recommended to avoid musculoskeletal injuries. After that you can increase that duration by 5 to 10 minutes per week in the frequency so that by the fourth the fifth week you're exercising five times per week. After progressing through that, increase the frequency, duration, and the intensity of the exercises until you reach your fitness goals.
The step test is done for 3 minutes consecutively stepping up and down on a 16.25 inch high box with a metronome set for men at 96 beats per minute and 88 beats per minute for women. after the three minutes is up check the heart rate between 5 to 20 seconds following the test.
