A new study says there is no limit to physical activities' benefits, effectively reducing cardiovascular disease risks.

Norfolk, Va. (Dec. 11, 2006) - Sailors assigned to the pre-commissioning unit (PCU) aboard the nuclear-powered aircraft carrier George H. W. Bush (CVN-77) come together for physical training exercises. 

There was a persisting notion that too much exercise could have adverse effects on the body. However, in a recent study, researchers believe that more exercise can prevent heart attacks and strokes.

Physical exercise can be a crucial prevention of cardiovascular diseases.

Study of Exercise and Cardiovascular Disease

The study published in the journal PLOS Medicine says that higher physical activity levels are linked to lower risks of cardiovascular disease. 

The researchers obtained accelerometer-measured moderate-intensity and intense exercises over 7 days from 2013 to 2015 for roughly 90,000 participants. 

Overall, 3,617 cases of cardiovascular disease were diagnosed in people between 40 and 69.

Through experiments, researchers observed that cases of cardiovascular disease such as stroke decrease as participants had increased physical exercise. 

Also, there was no threshold wherein the cardiovascular health of participants stopped improving.

Findings say that the top 25% had, on average, reduced risks between 48-57%.

In an article by CNN Health, Terence Dwyer, an author of the study and professor emeritus from the University of Oxford, says, "During the pandemic, because of lockdowns or self-imposed isolation, people have not been getting as much 'incidental' activity, particularly in relation to travel or move around an office,"

According to researchers, this means that people, now more than ever, need to maintain previous activity levels. The findings should provide confidence that exercise is something people should pay attention to. It should also prove that increasing physical activities beyond the norm will have an immense effect on a person's cardiovascular health.

Aiden Doherty, lead study author and associate professor at the University of Oxford, points out that the top 25% did 50 minutes of intense exercise like running. In comparison, those in the bottom 25% did less than 10 minutes per week of strenuous exercise.

Despite the upper 25% having the least amount of smokers, alcohol drinkers, and generally had healthy body weight, these factors were essential in the study. However, despite those, the correlation between increased exercise and decreased cardiovascular disease risks was still strong.

The research proves that exercise alone can significantly affect the risks of being diagnosed with any cardiovascular disease.

What are Cardiovascular Diseases?

According to the National Health Services UK, cardiovascular disease or CVD refers to conditions affecting either blood vessels or the heart. The disease is often associated with the build-up of fatty deposits inside the arteries increasing risks of blood clots.

The Center for Disease Control and Prevention reports that heart disease is the leading cause of death in the United States. Each year roughly 655,000 Americans, or 1 every 36 seconds, die from the disease.

This is why researchers are hopeful that the correlation between increase physical activity and cardiovascular disease prevention will motivate more people to spend time and focus on improving their physical health.
