The American Coronary heart Affiliation’s present suggestions, that are primarily based on HHS’s Bodily Exercise Pointers, are for a minimum of 150 minutes per week of moderate-intensity cardio train or 75 minutes per week or vigorous cardio train, or a mixture of each.
“The potential influence of bodily exercise on well being is nice, but it stays unclear whether or not participating in excessive ranges of extended, vigorous or average depth bodily exercise above the really useful ranges offers any extra advantages or dangerous results on cardiovascular well being,” mentioned Dong Hoon Lee, Sc.D., M.S., a analysis affiliate within the Division of Diet on the Harvard T.H.

“Our research leveraged repeated measures of self-reported bodily exercise over a long time to look at the affiliation between long-term bodily exercise throughout center and late maturity and mortality.”
Researchers analyzed mortality knowledge and medical information for greater than 100,000 adults gathered from two massive potential research: the all-female Nurses’ Well being Research and the all-male Well being Professionals Observe-up Research from 1988-2018. Members whose knowledge have been examined have been 63% feminine, and greater than 96% have been white adults. They’d a median age of 66 years and a median physique mass index (BMI) of 26 kg/m2 over the 30-year follow-up interval.
Members self-reported their leisure-time bodily exercise by finishing a validated questionnaire for both the Nurses’ Well being Research or Well being Professionals Observe-Up Research each two years. The publicly obtainable questionnaires, which have been up to date and expanded each two years, included questions on well being info, physician-diagnosed sicknesses, household medical histories and private habits similar to cigarette and alcohol consumption and frequency of train.
Train knowledge was reported as the common time spent per week on varied bodily actions over the previous 12 months. Reasonable exercise was outlined as strolling, lower-intensity train, weightlifting and calisthenics. Vigorous exercise included jogging, operating, swimming, bicycling and different cardio workouts.
The evaluation discovered that adults who carried out double the presently really useful vary of both average or vigorous bodily exercise every week had the bottom long-term danger of mortality.
The evaluation additionally discovered:

- Members who met the rules for average bodily exercise had an noticed 22-25% decrease danger of CVD mortality and 19-20% decrease danger of non-CVD mortality, for an total 20-21% decrease danger of demise from all causes.
- Members who carried out two to 4 occasions above the really useful quantity of long-term vigorous bodily exercise (150-300 min/week) had an noticed 27-33% decrease danger of CVD mortality and 19% non-CVD mortality, for an total 21-23% decrease danger of demise from all causes.
- Members who carried out two to 4 occasions above the really useful quantity of average bodily exercise (300-600 min/week) had an noticed 28-38% decrease danger of CVD mortality and 25-27% non-CVD mortality, for an total 26-31% decrease danger of mortality from all causes.
As well as, no dangerous cardiovascular well being results have been discovered among the many adults who reported participating in additional than 4 occasions the really useful minimal exercise ranges. Earlier research have discovered proof that long-term, high-intensity, endurance train, similar to marathons, triathlons and long-distance bicycle races, could enhance the danger of antagonistic cardiovascular occasions, together with myocardial fibrosis, coronary artery calcification, atrial fibrillation and sudden cardiac demise.
“This discovering could cut back the issues across the potential dangerous impact of participating in excessive ranges of bodily exercise noticed in a number of earlier research,” Lee famous.

Arnett, M.S.P.H., Ph.D., B.S.N., a previous president of the American Coronary heart Affiliation (2012-2013) and Dean and Professor within the Division of Epidemiology on the College of Kentucky School of Public Well being in Lexington, Kentucky. Arnett served as co-chair of the writing committee for the American Coronary heart Affiliation’s 2019 Guideline on the Main Prevention of Cardiovascular Illness, nevertheless, she was not concerned within the research.
She additionally said that: “Now we have additionally seen that getting greater than 300 minutes of moderate-intensity cardio bodily exercise or greater than 150 minutes of vigorous-intensity cardio bodily train every week could cut back an individual’s danger of atherosclerotic heart problems even additional, so it is smart that getting these further minutes of train can also lower mortality.”
