**[Cardiorespiratory endurance]** Cardiorespiratory endurance is an indication of a person's overall physical health. Cardiorespiratory endurance tests monitor how well the heart, lungs, and muscles perform during moderate to high-intensity exercise. Increasing cardiorespiratory endurance: - improves oxygen uptake in the lungs and heart - and can help a person sustain physical activity for longer. Other names for cardiorespiratory endurance: - cardiovascular fitness, - cardiovascular endurance, - cardiorespiratory fitness. **What is cardiorespiratory endurance?** Cardiorespiratory endurance measures - how well the body performs during long periods of exercise. - A person with high cardiorespiratory endurance can sustain high-intensity activities over an extended period without getting tired. - Measuring a person's cardiorespiratory endurance involves examining how well their body takes in and utilizes oxygen. - When a person inhales, their lungs fill up with air and some of the oxygen it contains passes into the bloodstream. - This oxygen-rich blood then travels to the heart, which circulates it around the body to the tissues and organs that need it. - The muscles require an adequate supply of oxygen and other nutrients to work properly during high-intensity or extended periods of exercise. - If the muscles do not get enough nutrients, waste products begin to accumulate and cause fatigue. A person's level of cardiorespiratory endurance can directly affect their physical performance. **[How is it measured?]** Tests that measure cardiorespiratory endurance include: ***Metabolic equivalents*** - Metabolic equivalents (METs) refers to the ratio between - the energy expended during physical activity - and the energy expended while at rest. ***Maximum oxygen uptake*** - Maximum oxygen uptake (VO2 max) test determines the maximum amount of oxygen the body is capable of using during high-intensity activities, such as sprinting or biking. - The VO2 max test typically involves - running on a treadmill - or pedaling on a stationary bike as fast as possible. - a chest strap or other body attachment that records their heart rate - and a face mask that measures oxygen consumption. undefined **[Why is it important?]** - Cardiorespiratory endurance indicates a person's level of aerobic health and physical fitness. This information can benefit everyone, not just professional athletes. - Having a high cardiorespiratory endurance generally means that a person can perform high-intensity exercise for longer. - People trying to lose weight may want to focus on increasing their cardiorespiratory endurance because doing higher-intensity aerobic activities can help a person burn more calories. - Scientific research also suggests some other potential health benefits from having an improved cardiorespiratory endurance. For example: - A 2017 study suggests that people with higher cardiorespiratory endurance are less likely to develop high blood pressure than those with a lower cardiorespiratory endurance. - In a 2015 study, researchers found a positive correlation between cardiorespiratory endurance levels and multitask performance among adults aged between 59 and 80 years. - Improving cardiorespiratory endurance may decrease the risk of - coronary heart disease - and all-cause mortality, **[How to improve it?]** People can improve their cardiorespiratory endurance through regular exercise. - The authors of a 2019 study reported that resistance training, endurance training, and high-intensity interval training led to improvements in cardiorespiratory endurance and muscular strength among adults who were aged 40--65 years old and who were not previously physically active. - Exercises that can help improve cardiorespiratory fitness include: - Running - power walking - swimming - dancing - jump rope - cycling - rowing - Kayak -- Canoe - All kind of AEROBIC physical activity **[Summary]** - Cardiorespiratory endurance is a measure of how well the heart, lungs, and muscles perform during moderate to high-intensity physical activity. - Getting regular physical activity, especially aerobic exercise, can improve cardiorespiratory endurance. - Aerobic exercises can help promote heart and lung health and improve how well the body circulates and utilizes oxygen.
