 “It is not surprising that moderate-intensity physical activity is
protective against cardiovascular disease mortality,” said lead
author Dafna Merom of the University of Western Sydney in Australia.
“I actually was surprised that light-intensity dancing was not
protective; I would expect that if the benefits of dance can be
attributed to the social and affective aspect of dancing than I
would expect light-intensity dancing to be beneficial,” Merom told
Reuters Health by email.
Merom and her colleagues pooled 11 population surveys form the U.K.
between 1995 and 2007, including more than 48,000 adults age 40 and
older with no heart disease at baseline.
The surveys included questions about frequency, duration and
intensity of dancing and walking over the previous four weeks. These
answers were linked to the National Death Registry.
Only about 3,100 of the 48,000 people surveyed reported dancing of
any intensity. Two-thirds of the group said they walked at any
intensity.
People who danced tended to be younger, have a lower body mass
index, were less likely to have long-standing illnesses and got more
overall physical activity than non-dancers.
During follow-up, there were 1,714 deaths due to cardiovascular
disease. People who reported moderate intensity dancing and walking
were less likely to die from cardiovascular disease than those who
did not, even after accounting for age, sex, socioeconomic status,
smoking, alcohol use, body mass index, chronic illness, psychosocial
distress and total physical activity, as reported online now in the
American Journal of Preventive Medicine.
The minimum recommended amount of moderate-intensity activity is 150
minutes a week, but this pooled analysis did not include a direct
measurement of how much people were dancing, Merom said.
“I would advise for those who find walking somewhat boring or those
that like to challenge themselves to try dancing,” she said. “First,
you can reach higher intensity than in walking while dancing, it may
be for short intervals but this all adds up, and you get some of the
benefits associated with vigorous-intensity physical activity.”

“But dance is also hard on the brain, as it is a highly coordinated
activity and requires skills and learning,” she said.
All styles of dance tend to have slow or quick tempo options, and
the quicker the better for heart health, Merom said.
“A large body of literature over 60 plus years shows that energy
expenditure from physical activity reduces risk of cardiovascular
disease,” said Dr. I-Min Lee of the Harvard T.H. Chan School of
Public Health in Boston, who was not part of the study. “We now
increasingly realize that how this energy is expended – from
walking, biking, swimming, dancing, playing with children, etc. –
doesn’t matter, so long as it is moderate in intensity.”
“I think what is important is that we need to stick with being
physically active – and to do so, one must do what one likes,” Lee
told Reuters Health by email. “So if you like to dance, great! If
you don’t and prefer to walk – then walk.”
