Cardiorespiratory endurance, also known as, cardiovascular fitness, is a major component in creating overall health and wellness. It leads to increased stamina, lower blood pressure levels, and effective management of diabetes. It can also help relieve stress, slow the aging process, improve the quality of sleep, and improve mental focus. Cardio exercise is vital to the health of the total body and mind.
The efficiency of the heart, lungs, and vascular system in delivering oxygen to the working muscle tissues, so that prolonged physical work can be maintained, cannot be overlooked. While a person’s ability to deliver oxygen to the working muscles is affected by many physiological functions, including heart rate, stroke volume, cardiac output, and maximal oxygen consumption, it is of the utmost importance to consistently work towards increasing cardiovascular fitness through exercise.

Understanding the relationship between cardiorespiratory endurance training and other categories of conditioning requires a review of changes that occur with increased aerobic, or anaerobic capacity. As aerobic/anaerobic capacity increases, general metabolism rises, muscle metabolism is enhanced, hemoglobin rises, buffers in the bloodstream increase, venous return is improved, stroke volume is improved, and the blood bed becomes more able to adapt readily to varying demands. Each of these results of cardiovascular fitness/cardiorespiratory conditioning will have a direct positive effect on muscular endurance, and an indirect effect on strength and flexibility.
If your goal is weight loss, weight management or simply to improve your overall health, cardiovascular exercise is essential for burning calories and conditioning your heart. Incorporating one or more “cardio” exercises like, cycling, running, treadmill, swimming, etc. will not only get that all important oxygen flowing through your body, the variety of activities and intensities will keep you challenged and your mind engaged.
