July 26: An analysis
of over 100,000 people over 30 years has found that adults who perform two
to four times the currently recommended amount of moderate or vigorous physical
activity per week have a significantly reduced risk of mortality, according to
new research published today in the American Heart Association's journal Circulation.
reduction was 21-23% for people who engaged in two to four times the
recommended amount of vigorous physical activity, and 26-31% for people who
engaged in two to four times the recommended amount of moderate physical
activity each week.
physical activity is accepted as reducing the risk of cardiovascular
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 an equivalent
combination of both intensities.
Heart Association's current recommendations, which are based on HHS's
Physical Activity Guidelines, are for at least 150 minutes per week of
moderate-intensity aerobic exercise or 75 minutes per week or vigorous aerobic
exercise, or a combination of both.
activity was defined as walking, lower-intensity exercise, weightlifting and
calisthenics. Vigorous activity included jogging, running, swimming, bicycling
and other aerobic exercises.
found that adults who performed double the currently recommended range of
either moderate or vigorous physical activity each week had the lowest
long-term risk of mortality.

to a study co-authored by Marily Oppezzo, a Stanford doctoral graduate in
educational psychology, and Daniel Schwartz, a professor at Stanford
Graduate School of Education, way back in 2014. Steve Jobs, the late co-founder
of Apple, was known for his walking meetings while Facebook’s Mark Zuckerberg
has also been seen holding meetings on foot.
