Atrial fibrillation is a condition that can make your heart race and put you at risk for stroke. But people who are obese are more prone to it and can reduce it if they exercise regularly.

According to a study, people with a body mass index (BMI) greater than 30 have a significantly higher risk of developing atrial fibrillation than the normal weight individuals.

“People who reported that they didn’t exercise at all had about double the risk of developing fibrillation, when compared to those who were physically active and whose body weight was normal,” said co-author Lars Elnan Garnvik from the Norwegian University of Science and Technology’s (NTNU).

“However, people who were obese but who exercised a lot limited the increase in risk to no more than approximately 50 per cent. This suggests that physical activity is good for limiting the increased risk of atrial fibrillation in obese people,” Garnvik added.

For the study, published in the European Journal of Preventive Cardiology, the research team involved 43,602 men and women who participated in the study between 2006 and 2008.

“Physical activity and exercise reduce a lot of the known risk factors for atrial fibrillation, like high blood pressure, high blood sugar, high cholesterol and chronic inflammation,” said co-author Lars Elnan Garnvik from the Norwegian University of Science and Technology (NTNU).

“Physical activity can also improve a person’s fitness level, and we know that people in good shape have a reduced risk of heart failure,” Garnvik added. (IANS)

Exercise Cuts Risk of Chronic Disease in Older Adults

For the study, the researchers interviewed more than 1,500 Australian adults aged over 50 and followed them over a 10-year period

Older adults who exercise above the current recommended levels may have a reduced risk of developing chronic disease as compared to those who do not exercise, a new study has found.

The findings suggested that people who engaged in the highest levels of total physical activity were twice as likely to avoid stroke, heart disease, angina, cancer and diabetes, and be in optimal physical and mental shape 10 years later.

Older adults who did more than 5,000 metabolic equivalent minutes (MET minutes) each week saw the greatest reduction in the risk of chronic disease, suggested the study published in the journal Nature Scientific Reports.

“Some older adults may not be able to engage in vigorous activity or high levels of physical activity,” said lead author Bamini Gopinath, Associate Professor at the University of Sydney.

“But we encourage older adults who are inactive to do some physical activity, and those who currently only engage in moderate exercise to incorporate more vigorous activity where possible,” Gopinath added.

Currently, the World Health Organisation (WHO) recommends at least 600 MET minutes of physical activity each week. That is equivalent to 150 minutes of brisk walking or 75 minutes of running, the researchers mentioned.

“Our findings suggest that physical activity levels need to be several times higher than what the WHO currently recommends to significantly reduce the risk of chronic disease,” said Gopinath.

“Our study showed that high levels of physical activity increase the likelihood of surviving an extra 10 years free from chronic diseases, mental impairment and disability,” Gopinath noted. (IANS)
