Along with greater strength and more defined muscles, a fitness goal worth striving for is greater cardiorespiratory endurance. Maybe you know it simply as \u201cendurance.\u201d Either way, it\u2019s a skill that can improve your performance in just about any athletic endeavor, allowing you to exercise harder and longer \u2014 and reach your goals faster.<\/p>\n

If you can barely run a mile without keeling over, though, don\u2019t stress. As with any other fitness skill \u2014 like\u00a0building strength, enhancing explosive power, becoming more\u00a0flexible\u00a0\u2014 you can improve your cardiorespiratory endurance with the right\u00a0cardio activities\u00a0and\u00a0workout regimen. Here\u2019s a look at how you can do that, and what exactly this term means.<\/p>\n

What Is Cardiorespiratory Endurance?<\/h2>\n

\u201cCardiorespiratory endurance is the ability of your heart, blood vessels, and lungs to deliver oxygen to working muscles,\u201d says Trevor Thieme, C.S.C.S.<\/p>\n

The more efficient and effective your body becomes at doing that, the longer you can sustain vigorous physical activity, and the fitter you\u2019ll become. Cardiorespiratory is often measured by your VO2 max, a number that represents the greatest volume of oxygen you body can recruit during exercise, notated as ml\/kg\/min (milliliters of oxygen per kilogram of bodyweight per minute).<\/p>\n

Cardiorespiratory vs. Cardiovascular Endurance<\/h2>\n

These two terms are often used interchangeably, and while they both relate to how long and how hard you can perform physical activity, they are slightly different.<\/p>\n

Cardiorespiratory\u00a0endurance involves the heart, blood vessels, and lungs, while cardiovascular\u00a0endurance just includes the heart and blood vessels, says\u00a0William P. Kelley, C.S.C.S., ATC.<\/p>\n

\u201cCardiovascular endurance is related to the cardiorespiratory function, as blood is what carries the oxygen,\u201d he explains. \u201cBut it\u2019s more about the cardiac muscles\u2019 ability to fire repeatedly and forcefully.\u201d The cardiorespiratory system, on the other hand, also encompasses the gas exchange that occurs between the heart and lungs, Kelley says.<\/p>\n

If you need a trick to remember the difference between the two, break down the words. Vascular refers to vessels \u2014 in this case, blood vessels \u2014 and respiratory refers to the respiration system \u2014 aka your lungs.<\/p>\n

Why Is Cardiorespiratory Endurance Important?<\/h2>\n

Increasing your endurance is key to improving your overall fitness. \u201cThe greater your cardiorespiratory endurance, the longer and harder you can push yourself during a workout or athletic event,\u201d Thieme says. This helps with traditional\u00a0cardio activities\u00a0\u2014 like\u00a0running on a treadmill\u00a0or cycling \u2014 allowing you to go farther, faster.<\/p>\n

But it also gives you an edge in other types of workouts. \u201cIf you\u2019re doing\u00a0HIIT, for example, it means being able to sustain a higher exercise intensity before fatigue starts taking a toll on performance,\u201d he says.<\/p>\n

Good cardiorespiratory and cardiovascular endurance is also helpful with certain kinds of strength workouts, like circuit training, where stamina is important. \u201cAll in all, it translates into greater exercise capacity,\u201d says Thieme. \u201cAnd the greater your exercise capacity, the more calories you\u2019ll burn and\u00a0the more fat you\u2019ll shed.\u201d<\/p>\n

And beyond enhanced fitness and improved body composition, greater cardiorespiratory endurance can also lead to a stronger, healthier heart, which Thieme says is \u201chugely important for longevity and quality of life.\u201d<\/p>\n

What Is the Best Way to Improve Cardiovascular Endurance?<\/h2>\n

If you want to challenge your cardiorespiratory and cardiovascular endurance, start by engaging in\u00a0aerobic activity. That includes any exercise or workout that increases your heart rate and relies on the respiratory (lungs) and circulatory (heart) systems to deliver oxygen to your working muscles for energy production.<\/p>\n

(Think: aerobic activity like distance running and interval training, not anaerobic activity like weightlifting.)<\/p>\n

The Centers for Disease Control and Prevention (CDC) recommends the following as the\u00a0minimum amount of exercise for adults: two strength-training workouts and either 2.5 hours of moderate-intensity aerobic exercise (steady-state exercise, like distance running) or 1.5 hours of high-intensity aerobic exercise (interval training, like HIIT) per week.<\/p>\n

If you\u2019re just\u00a0beginning your fitness journey, stick to moderate-intensity cardio. But if you\u2019ve already built a strong fitness foundation and have limited time to exercise, your\u00a0cardio workouts\u00a0should emphasize interval training.<\/p>\n

Either way, \u201cboth steady-state exercise and interval training have been shown to lead to\u00a0similar increases in cardiorespiratory endurance,\u201d Thieme says.<\/p>\n
