How fit are your heart and lungs? Let's find out exactly what Cardiovascular Endurance is!

Do you sometimes find it hard to breathe when doing a little strenuous work, climbing stairs, or walking a little distance? Do you feel like you're getting tired? Have you ever wondered why this happens? One reason for this is that there are some weaknesses in the functioning of our heart and lungs. That's what we're going to talk about today, namely , cardiovascular endurance .

What is Cardiovascular Endurance?

Simply put, when you exercise, that is, when you do some strenuous work, your heart and lungs should be able to supply your body with the right amount of oxygen . This is what we call cardiovascular endurance, or aerobic fitness .

Imagine that you have good cardiovascular endurance . Then you can do moderate intensity exercise for a long time without getting tired. You can do high intensity exercise for a short time without any difficulty. The reason for this is that your body is able to continuously receive the required amount of oxygen during exercise. Just like a well-running car gets a regular supply of fuel.

Why is cardiovascular endurance important to us?

Having good cardiovascular endurance allows your body to move blood more efficiently throughout your body. This allows your cells to get the oxygen they need. This oxygen is what provides the energy, or rather fuel, for the cells in our tissues and muscles .

Think of it this way: every cell in your body is like a tiny engine. These engines need oxygen to function. So, the heart and lungs are the two main places that pump this fuel. When they work well, the whole body works well.

What are the benefits of increasing cardiovascular endurance?

There are not just one or two benefits to this, there are many. Let's look at some of the main benefits:

• Helps keep your cholesterol and blood pressure at a good level : This is very important. Because if both of these get out of control,Big problems like heart disease can occur.
• Protects you from many diseases: Especially reducing the risk of developing heart and blood vessel conditions.
• Helps you live healthier and longer: Who wouldn't want to live healthier, happier and longer, right?
• Strengthens your heart and lungs: Just like the limbs of someone who exercises daily become stronger.
• Daily tasks (e.g., lifting a laundry basket, climbing stairs) can be done with less effort: It's a pain to do even a small task, isn't it? As this ability develops, the feeling of fatigue decreases.
• Improves brain function: This also helps improve things like memory and attention, as the brain receives a good blood supply.
• Increases mental well-being: When we exercise, our bodies release happy hormones like endorphins. This reduces mental stress and makes us feel happy and relaxed.
• Improves quality of life: You will realize how much easier life is when you can work without getting sick often and without fatigue.

How do we measure cardiovascular endurance?

There are special devices that can measure this. These measure how much oxygen your body can consume (`(Maximum Oxygen Consumption)` or `(VO2 max)`) when you exercise. There are several tests that can be used to do this:

• Riding a stationary bike at different speeds: A test that is done by gradually increasing the speed.
• Walking or running on a treadmill: This is done by changing the speed and incline.
• Running a set distance in a set time: For example, measuring the maximum distance you can run in 12 minutes.
• Doing a shuttle run: This involves seeing how many times you can run between two points about 20 meters (66 feet) apart at a set speed. The advantage of this is that it doesn't require any special equipment. A coach might use this method to test the endurance of children on a school sports team.

What are the results of a cardiovascular endurance test usually like?

This varies from person to person.

• The maximum oxygen consumption (usage) of an active young person may be between 35 and 50 milliliters of oxygen per kilogram of body weight per minute.
• For an endurance athlete, this figure might be between 70 and 85 milliliters of oxygen per kilogram per minute. Imagine what a difference that makes!
• Someone who has suffered a strokeThis value may be as low as 8 to 23 milliliters of oxygen per kilogram per minute. However, even for them, this value can be improved by 10% to 15% by doing moderate aerobic exercise. That's really good news, isn't it?

How do we develop this cardiovascular endurance?

The best part is that this is something anyone can improve. All you have to do is engage in activities that increase the amount of oxygen you breathe and increase your heart rate.

• Start small: You can start with exercises like this for about 10 or 15 minutes a day.
• Gradually increase: Then you can gradually challenge your body by adding a few minutes each day (the recommendation is for adults to exercise for at least 150 minutes a week).
• Increase Intensity: In addition to increasing the time you exercise, you can also increase the distance you walk, or increase the incline on a treadmill to increase the difficulty. All of these things will force your body to work harder, which will improve your endurance.

A study of elementary school children found that increasing their physical education class from two days a week to four days a week increased their cardiovascular endurance.

Sprint Interval Training (SIT)

This is also a very effective method. Several studies have found that people who did Sprint Interval Training (SIT) for two to eight weeks improved their cardiovascular endurance by 4% to 13.5%.

Here's how to do it:

• About three days a week.
• They run as fast as they can (push their hardest) for 10 to 30 seconds at a time.
• Then take a two to five minute rest (recover) and do it again in the same way.
• Do about 3 to 7 rounds like this.

High-Intensity Interval Training (HIIT)

This is also a very popular method. ``High-Intensity Interval Training`` (HIIT) is a low-intensity exercise followed by short periods of high-intensity exercise. It's like running fast, then sprinting fast again.

One study found that high-intensity interval training (HIIT) improved people's cardiovascular endurance by an astonishing 38% to 79%!

What are these exercises that improve cardiovascular endurance?

Any exercise that increases your breathing rate and heart rate will help with this. Here are some examples:

• Swimming
• Riding a bike
• Dancing
• Jogging
• Walking
• Jumping rope
• Climbing stairs

Finally, take-home message:

No matter your age, you can improve your cardiovascular fitness. It's never too late. You can ask your doctor about this and ask for help in developing an exercise plan that's right for you.

Remember, start small, increase gradually, and keep going without giving up. Then you will see the results for yourself. You will feel better and be able to do your daily tasks more easily. So, let's start thinking about this today and make your heart and lungs a little more fit, shall we?
