Research Reveals How Fitness Affects the Risk Of Developing Heart Disease

In the current world, the awareness regarding health issues is much more in comparison with past times. People now keep a strict check on their diets and try to fulfill their daily need of exercise. This is because of a variety of factors.

For example, the availability of sources to confirm any doubt you have in your mind is a big facility. You can look up proper scientific journals to know whether a diet is worth trying or know.

There are also several opinions and demonstrations present on the internet. Gone are the days when you needed to go through numerous books to find a single answer.

Additionally, the presence of gadgets and technology to aid your fitness journey also makes a big difference. One good example of this is the popular Fitbit watches. You probably see every other person wearing Fitbits at work. Advanced models of this gadget can also help track water intake and blood pressure!

However, amidst all these facilities, some health conditions are still prevalent in the world. You may have noticed that even the healthiest of people experience cardiovascular issues. Why is this so? A recent study highlights this very issue.

Previous research shows the benefits of exercise and its role in the health of the heart. The new one, published in the European Heart Journal, corroborates how physical activity along with a good cardiorespiratory fitness can cut down the risk of heart-related conditions by half.

How Was the Study Conducted?

The new study, conducted by Bjarne Nes, from the Norwegian University of Science and Technology’s Cardiac Exercise Research Group in Trondheim, and a team of researchers shows the importance of cardiorespiratory fitness in an individual.

Cardiorespiratory fitness refers to the ability of the body to provide it with an appropriate amount of oxygen during physical activity. Precisely, it can show how well are the respiratory system and the heart working.

To check the role of cardiorespiratory fitness, the researchers looked at data of around 4,500 people from a health survey known as HUNT3. None of the participants had symptoms of cardiovascular disease, lung malfunction, or high blood pressure at this time.

At the same time, about 80% of them also had a minor risk of developing a cardiovascular problem in ten years.  To check their cardiorespiratory fitness, the golden standard method was used. The key is to note the maximum oxygen intake of a person in this method.

What Did the Study Show?

147 out of all the participants had a cardiovascular event – either Angina Pectoris or a heart attack – by the end of the study. The researchers here noted a correlation. People who developed these conditions typically had low levels of cardiorespiratory fitness.

In addition, the higher the levels of cardiorespiratory fitness in a person, the lower were his/her chances of having a heart-related problem.  Secondly, small improvements in the fitness levels also had a great effect on the risk. This is to say even a 3.5 percent increase in fitness led to a 15 percent decrease in risk of a heart attack or angina.

The corresponding and last author of the study, Nes, says that such results should make people take exercise more seriously. Using it as a preventive method, it can lower the risk of cardiovascular diseases even in healthy people effectively.
