Cardiorespiratory fitness reduces heart problems, research reports

New research, published in the European Heart Journal, suggests that people with higher cardiorespiratory fitness have a lower risk of heart-related problems than those with lower levels of cardiorespiratory fitness.

Cardiorespiratory fitness is described as the body’s ability to supply oxygen to the muscles during exercise. And the muscles’ ability to use that oxygen.

It is improved through physical activity or exercise. It is proven to decrease the risk of stroke, heart disease, and other diseases. Also, it improves heart and lung function.

Individuals who exercise regularly are healthier than others. Doctors often recommend exercising to persons who are at risk of certain condition- specifically chronic heart-related difficulties. A new study points out that people without any related signs should, too, exercise.

Why are heart problems a big concern?

In the U.S, heart problem remains the leading cause of death. It is responsible for the deaths of about 610,000 people each year.

There are many types of heart conditions. Coronary artery disease is common heart disease. It often results in a sudden heart attack. However, even healthy individuals might be at risk of a heart attack. That is because physical fitness does not promise good cardiorespiratory fitness.

Even if somebody has no signs of heart problems, low cardiorespiratory fitness may lead to future cardiovascular disease. Thus, healthy people should exercise regularly to keep heart disease at bay.

How was the research conducted?

The researchers along with Letnes checked the cardiorespiratory fitness of 4,527 people. They were the participants of large HUNT3 study in 2006-08. All of them were considered fit and healthy.

These participants were required to wear an oxygen mask and a heart monitor while working out. Through this, the researchers checked their cardiorespiratory fitness or ability to provide oxygen during the exercise.

The standard measure of cardiorespiratory fitness is VO2max. That is the maximum oxygen which body can use during a specified period of usually intense exercise.” It depends on a person’s weight, as well on the strength and health of their respiratory system.

Moreover, the participants’ family history, blood pressure, alcohol intake, dietary habits, body mass index, smoking status, and cholesterol levels were also examined. This research went on for almost nine years.

What were the outcomes?

After nine years, 3.3% or 147 of the participants were affected by heart disorder. Some of the individuals developed it, had coronary artery bypass graft, or died from it. Participants with better cardiorespiratory fitness were found to have a lower risk of cardiovascular disease throughout the research.

Moreover, the risk of developing heart-related problems and heart attack reduced by 15% with every metabolic equivalent. This proves that exercise is important for all including those who are otherwise considered fit.

The lead author of the research also added that exercise should be recommended as a preventive measure. 30-45 minutes of exercise is adequate to prevent heart disease in all individuals along with a healthy lifestyle.
