A new study found that adults who exercised 150 to 600 minutes per week had the lowest risk of death

Highlights of the study:

  • An analysis of the physical activity and medical records of more than 100,000 people over 30 years found that people who engaged in moderate (150-300 minutes/week) or vigorous physical activity (75-150 minutes/week), respectively, as currently recommended by the US Department of Health and Human Services, all 20-21% and 19% lower risk of death due to causes.

  • People who did two to four times the recommended amount of physical activity (150 to 600 minutes per week) had a further reduction in all-cause mortality.

(NewMediaWire) — July 25, 2022 — DALLAS analyzed more than 100,000 participants over a 30-year follow-up period, showing that adults who did two to four times the recommended amount of moderate or vigorous physical activity per week did so, according to a new study published today in the American Heart Association’s flagship, peer-reviewed journal. Accordingly, the risk of death decreases. circulation. It was 21-23% for people who got two to four times the recommended amount of physical activity, and 26-31% for people who did two to four times the recommended amount of moderate physical activity each week.

Regular physical activity reduces the risk of cardiovascular disease and early death. The 2018 United States Department of Health and Human Services’ Physical Activity Guidelines for Americans recommended that adults get at least 150-300 minutes of moderate-intensity physical activity per week or 75-150 minutes of moderate-intensity physical activity per week. a combination of two intensities. Current American Heart Association recommendations, based on HHS’s Physical Activity Guidelines, are at least 150 minutes of moderate-intensity aerobic exercise per week or 75 minutes of vigorous-intensity aerobic exercise per week, or a combination of both.

“The potential effects of physical activity on health are large, but it remains unclear whether prolonged intensity, vigorous or moderate physical activity above recommended levels has any additional benefits or detrimental effects on cardiovascular health,” said Dong Hun Lee. . , Sc.D., MS, is a research fellow in the Department of Nutrition at the Harvard TH Chan School of Public Health in Boston. “Our study used repeated measures of self-reported physical activity over decades to examine the association between long-term physical activity and mortality in middle and late adulthood.”

The researchers analyzed mortality data and medical records of more than 100,000 adults from two large prospective studies: the all-female Nurses’ Health Study and the all-male Health Professionals Follow-Up Study from 1988 to 2018. Of the participants whose data was checked, 63% were women, and more than 96% were white men. Their mean age was 66 years and mean body mass index (BMI) was 26 kg/m.two Over the next 30 years.

Participants self-reported their leisure-time physical activity by filling out a validated questionnaire for the biennial Nurses’ Health Survey or health professionals’ follow-up survey. The publicly available questionnaires, updated and expanded every two years, included questions about health information, physician-diagnosed diseases, family medical history, and personal habits such as smoking, alcohol consumption, and frequency of exercise. Exercise data were reported as the average time spent per week in various physical activities during the past year. Moderate activity was defined as walking, low-intensity exercise, weight lifting, and calisthenics. Vigorous activity includes running, jogging, swimming, cycling, and other aerobic exercises.

The analysis showed that adults who did twice the recommended range of moderate or vigorous physical activity each week had the lowest long-term risk of death.

The analysis also found:

  • Participants who met the guidelines for vigorous physical activity experienced a 31% reduction in the risk of CVD death and a 15% reduction in the risk of non-CVD death, for an overall 19% reduction in the risk of death from all causes.

  • Participants who met the guidelines for moderate physical activity had a 22-25% lower risk of CVD death, a 19-20% lower risk of non-CVD death, and a 20-21% lower risk of all-cause death overall.

  • Participants who performed two to four times the recommended amount of long-term vigorous physical activity (150-300 minutes per week) had a 27-33% risk of CVD death and a 19% risk of non-CVD death. -23% lower risk of death from all causes.

  • Participants who performed two to four times the recommended amount of moderate physical activity (300-600 min per week) had a 28-38% increased risk of CVD mortality and a 25-27% increased risk of non-CVD mortality. The risk of death from all causes is reduced by 31%.

In addition, no adverse effects on cardiovascular health were found among adults who exceeded four times the minimum recommended activity level. Previous studies have shown that long-term, high-intensity, endurance exercise, such as marathons, triathlons, and long-distance bicycle races, increases the risk of cardiovascular disease, including myocardial fibrosis, coronary artery calcification, atrial fibrillation, and stroke. cardiac death.

“This finding may reduce concerns about the harmful effects of high levels of physical activity seen in several previous studies,” Lee said.

However, long-term, high-intensity physical activity (300 minutes per week) or moderate-intensity physical activity (600 minutes per week) more than four times the recommended weekly minimum did not provide an additional reduction in mortality risk.

“Our study provides evidence that can help people choose the right amount and intensity of physical activity throughout their lives to maintain good health,” Lee said. “Our findings support current national guidelines for physical activity and further suggest that maximum benefit may be achieved by performing moderate to vigorous levels of activity or a combination of moderate to vigorous activity.”

He also noted that people who engaged in less than 75 minutes or less than 150 minutes of moderate activity per week had the greatest benefit in reducing mortality by consistently doing about 75 to 150 minutes of vigorous activity or 150 to 300 minutes of moderate exercise. per week, or a combination of both, long-term.

“We’ve known for a long time that moderate to vigorous physical activity can reduce a person’s risk of death from atherosclerotic cardiovascular disease,” said Donna K. Arnett, MSPH, Ph.D, BSN, Past President. American Heart Association (2012-2013) and Dean and Professor of Epidemiology at the University of Kentucky College of Public Health in Lexington, Kentucky. Arnett served as co-chair of the American Heart Association’s 2019 Cardiovascular Disease Prevention Guideline Writing Committee, but he was not involved in the study. “Also, we found that doing more than 300 minutes of moderate-intensity aerobic physical activity or more than 150 minutes of vigorous-intensity aerobic physical activity each week further reduced a person’s risk of developing atherosclerotic cardiovascular disease, so even additional minutes of exercise may reduce mortality.”
