'No limit' - the more exercise the better, heart health study finds

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.

Researchers studied 90,000 United Kingdom residents who had no prior cardiovascular disease and had them wear an accelerometer to measure their physical activity over a week. What's more, there was no threshold where the effects of exercise stopped improving cardiovascular health, the study found.

Overall, there were 3,617 cases of cardiovascular disease diagnosed in the participants, who were part ofthe wider UK Biobank study of people between 40 and 69 years old.

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

'The potential risk reduction estimated in those engaging in relatively high levels of activity is substantial and justifies a greater emphasis on measures to increase levels of physical activity in the community'.

"This means that they need to take more purposeful activity to maintain even what they were doing previously". The findings should provide confidence that exercise is something people should pay attention to.

This research, which involved more than 90,000 people studied over a five-year period, found that those in the top 25% of people who engaged in vigorous-intensity activity had an average reduction in risk heart disease of between 54% and 63%.

These results, the researchers said, demonstrated that exercise alone has a significant effect on the risk of being diagnosed with cardiovascular disease.

Cardiovascular disease is the leading world's number one cause of death - killing nearly 18 million people a year globally, according to the World Health Organization (WHO).

Physical activity can be associated with a lower risk of cardiovascular disease, with the greatest benefit seen among those who are the most active, research has confirmed.

Physical exercise can be a crucial prevention of cardiovascular diseases.

Aiden Doherty, an Oxford professor who worked with Ramakrishnan, said the study's results were a robust endorsement for World Health Organization advice that people should aim to do at least 150 to 300 minutes of moderate to vigorous aerobic exercise a week.

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 is "no limit" to the benefits that can be gained in terms of heart health and reduced risk of cardiovascular disease from exercise, according to a new study.

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. This included 2,220 men and 1,397 women.

One way to do your recommended 150 minutes of weekly physical activity is to do 30 minutes on 5 days every week.
