Adults who exercise 2-4 times per week have lower risk of mortality: Study – Times of India

WASHINGTON: In a study of more than 100,000 participants and a 30-year follow-up period, it was found that those who engaged in two to four times the amount of weekly moderate or vigorous physical exercise currently advised had a higher mortality risk. The risk is much less. ,
For those who did two to four times the recommended amount of vigorous physical activity each week, the reduction was 21–23%, and for those who did the same amount of moderate physical activity each week, it was 26–31%. Was. for the new study.
The study’s findings were published in American Heart AssociationHead of the peer-reviewed journal Circulation.
It is well documented that regular physical activity is associated with a lower risk of heart disease and premature death. In 2018, the United States Department of Health and Human Services’ Physical Activity Guidelines for Americans recommended that adults engage in at least 150–300 minutes/week of moderate physical activity or 75–150 minutes/week of vigorous physical activity, or equivalently a combination of both intensities. Current recommendations from the American Heart Association, which are based on: familiesPhysical activity guidelines are for at least 150 minutes per week of moderate-intensity aerobic exercise, or 75 minutes per week of vigorous aerobic exercise, or a combination of both.
Dong Hoon said, “The potential effect of physical activity on health is great, yet it is not clear whether engaging in high levels of prolonged, vigorous or moderate-intensity physical activity above recommended levels has any additional benefits on cardiovascular health. or have harmful effects.” Took, Sc.D., MS, a research associate in the department of nutrition at the Harvard T.H. Chan School of Public Health in Boston. “Our study took advantage of repeated measures of self-reported physical activity over decades to examine the association between long-term physical activity during middle and late adulthood and mortality.”
Researchers analyzed mortality data and medical records for more than 100,000 adults collected from two large prospective studies: the All-Female Nurses’ Health Study and the All-Male’s Health Professionals Follow-up Study from 1988-2018. Of the participants whose data were examined, 63% were female, and more than 96% were white adults. They had a mean age of 66 years and a mean body mass index (BMI) of 26 kg/m2 over a 30-year follow-up period.
Participants self-reported their leisure-time physical activity every two years by completing a validated questionnaire for the Nurses’ Health Study or the Health Professionals Follow-up Study. The publicly available questionnaire, which was updated and expanded every two years, included questions about health information, physician-diagnosed diseases, family medical history and personal habits such as cigarette and alcohol consumption and frequency of exercise. Exercise data were reported as the mean time spent per week on various physical activities over the past year. Moderate activity was defined as walking, low-intensity exercise, weight lifting and calisthenics. Vigorous activity included jogging, running, swimming, cycling and other aerobic exercises.
The analysis found that adults who performed twice the currently recommended range of moderate or vigorous physical activity each week had the lowest long-term risk of mortality.
The analysis also found:
*Participants who met the guidelines for vigorous physical activity had a 31% lower risk of CVD mortality and a 15% lower risk of non-CVD mortality, for an overall 19% lower risk of death from all causes.
*Participants meeting guidelines for moderate physical activity saw a 22-25% lower risk of CVD mortality and a 19-20% lower risk of non-CVD mortality, with an overall 20-21% lower risk of death from all causes to risk.
*Participants who performed two to four times the recommended amount of long-term vigorous physical activity (150–300 min/week) saw a 27–33% lower risk of CVD mortality and a 19% lower risk of non-CVD mortality Went. 21-23% reduced risk of death from all causes.
*Participants who performed two to four times the recommended amount of moderate physical activity (300-600 min/week) had a 28-38% lower risk of CVD mortality and 25-27% for non-CVD overall 26 mortality rate was observed. -31% Low risk of all-cause mortality.
In addition, no harmful heart health effects were found in adults who reported engaging in more than four times the recommended minimum activity levels. Previous studies have found evidence that long-duration, high-intensity, endurance exercise, such as marathons, triathlons and long-distance cycling, can reduce the risk of adverse cardiovascular events, including myocardial fibrosis, coronary artery calcification, atrial fibrillation and sudden can increase. Heart death.
“This finding may allay concerns around the potentially harmful effect of engaging in high levels of physical activity seen in many previous studies,” Lee said.
However, engaging in prolonged, high-intensity physical activity (?300 min/week) or moderate-intensity physical activity (?600 min/week) at levels greater than four times the recommended weekly minimum did not result in any additional reduction in risk I. Death.
“Our study provides evidence to guide individuals to choose the right amount and intensity of physical activity over their lifetime to maintain their overall health,” Lee said. “Our findings support current national physical activity guidelines and further suggest that maximum benefit can be achieved by performing moderate or high levels of moderate or vigorous activity or a combination.”
They also noted that people who did less than 75 minutes of vigorous activity or less than 150 minutes of moderate activity per week had a reduction in mortality from about 75-150 minutes of vigorous activity or 150-300 minutes of moderate exercise consistently. But you can get more benefits. per week, or an equivalent combination of both over a longer period.
“We have known for a long time that moderate and intense levels of physical exercise can reduce a person’s risk of both atherosclerotic cardiovascular disease and mortality,” says Donna K. Arnett, MSPH, PhD, BSN, former president. Dean and Professor in the Department of Epidemiology at the American Heart Association (2012–2013) and the University of Kentucky College of Public Health in Lexington, Kentucky. arnet Served as co-chair of the writing committee for the American Heart Association’s 2019 Guidelines on primary prevention of heart diseaseHowever, she was not involved in the study. “We have also seen that doing more than 300 minutes of moderate-intensity aerobic physical activity or more than 150 minutes of vigorous-intensity aerobic physical exercise each week can further reduce a person’s risk of atherosclerotic heart disease, So it makes sense that getting those extra minutes of exercise could also reduce mortality.”
