An analysis of the physical activity and medical records of more than 100,000 people over a 30-year period found that individuals who performed the current US Department of Health and Human Services recommended range of moderate duration (150-300 minutes/week) or vigorous physical activity (75-150 minutes/week). week), respectively, a decrease in the risk of death was observed by 20-21% and 19% from all causes.
It was observed that individuals who performed two to four times the recommended amount of physical activity (150-600 minutes/week) had a greater reduction in all-cause mortality.

(NewMediaWire) – Jul 25, 2022 – DALLAS An analysis of more than 100,000 participants over a 30-year follow-up period found that adults who performed two to four times the currently recommended amount of moderate or vigorous physical activity per week had a significantly reduced risk of death. , according to new research published today in the leading peer-reviewed journal of the American Heart Association Rotation. The reduction was 21-23% for people who did two to four times the recommended amount of vigorous physical activity, and 26-31% for people who did two to four times the recommended amount of moderate physical activity each week.
It is well documented that regular physical activity is associated with a reduced risk of cardiovascular disease and premature death. In 2018, the US Department of Health and Human Services’ Physical Activity Guidelines recommended that American adults get at least 150-300 minutes/week of moderate physical activity or 75-150 minutes/week of vigorous physical activity, or the equivalent of a combination of both severity. The current American Heart Association recommendations, which are based on the HHS Physical Activity Guidelines, are at least 150 minutes per week of moderate-intensity aerobic activity or 75 minutes per week of vigorous aerobic activity, or a combination of both.
Dong Hun Lee said, “The potential impact of physical activity on health is significant, yet it remains unclear whether engaging in high levels of prolonged, vigorous or moderate intensity physical activity above recommended levels provides any additional benefits or adverse effects on health. Cardiovascular Health. , MA, Research Associate in the Department of Nutrition at 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 relationship between long-term physical activity during mid and late adulthood and mortality.”
The researchers analyzed mortality data and medical records for more than 100,000 adults collected from two large prospective studies: the Whole Nurses’ Health Study and the Male Health Professionals Follow-up Study Only from 1988-2018. The participants whose data were examined were 63% female, and over 96% were white adults. They had a mean age of 66 years and a mean body mass index (BMI) of 26 kg/m2 During the 30-year follow-up period.
Participants self-reported their leisure-time physical activity by completing a validated questionnaire from either the Nurses’ Health Study or the Health Professionals Follow-up Study every two years. Publicly available questionnaires, which were updated and expanded every two years, included questions about health information, doctor-diagnosed illnesses, family medical history and personal habits such as cigarette and alcohol consumption and exercise frequency. Exercise data is reported as the average time spent a week in various physical activities over the past year. Moderate activity was defined as walking, low-intensity exercise, weight lifting, and gymnastic exercises. Vigorous activities included jogging, running, swimming, cycling, and other aerobic exercise.
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 death.
The analysis also found:
Participants who met the guidelines for vigorous physical activity had a 31% lower risk of death from cardiovascular disease and a 15% lower risk of death not related to cardiovascular disease, for a 19% lower risk of death from all causes.
Participants who met the guidelines for moderate physical activity had a 22-25% lower risk of death from cardiovascular disease and a 19-20% lower risk of death not related to cardiovascular disease, for a 20-21% lower risk of death from all causes.
Participants who performed two to four times higher than the recommended amount of long-term vigorous physical activity (150-300 minutes/week) had a 27-33% lower risk of cardiovascular death and 19% lower risk of non-CVD-related deaths. For a total of 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 minutes/week) experienced a 28-38% reduction in the risk of CVD mortality and a 25-27% reduction in non-CVD related mortality, for a total 26-31% reduced risk of death from all causes.
In addition, no adverse effects on cardiovascular health were found among adults who reported participating in more than four times the minimum recommended activity levels. Previous studies have found evidence that long-term, high-intensity endurance exercise, such as marathons, triathlons, and long-distance cycling, may increase the risk of adverse cardiovascular events, including myocardial fibrosis, coronary artery calcification, and sudden and atrial fibrillation. cardiac death.
“This finding may reduce concerns about the potentially harmful effect of engaging in high levels of physical activity that has been observed in several previous studies,” Lee noted.
However, engaging in long-term, high-intensity (300 min/week) or moderate-intensity (600 min/week) physical activity at levels greater than four times the minimum recommended weekly provided no further reduction in the risk of death.
“Our study provides evidence to guide individuals to choose the appropriate 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 benefits can be achieved by performing moderate to high levels of moderate, vigorous or combination activity.”
It also indicated that people who perform less than 75 minutes of vigorous activity or less than 150 minutes of moderate activity per week may have greater benefits in reducing mortality by performing approximately 75-150 minutes of vigorous activity or 150-300 minutes. of moderate exercise. weekly, or an equivalent of both, in the long run.

Arnett served as co-chair of the 2019 American Heart Association Guidelines Writing Committee on Primary Prevention of Cardiovascular Disease, however, she was not involved in the study. “We’ve also seen that getting more than 300 minutes of moderate-intensity aerobic physical activity or more than 150 minutes of vigorous-intensity aerobic physical activity each week may reduce a person’s risk of developing atherosclerotic cardiovascular disease even more, so it makes sense that these The extra minutes of exercise may also reduce the mortality rate.”
