alone means it is especially important for her memory and thinking to remain clear.>>Speaker 3: I have to be in charge of a
household and an automobile and my health.>>Catherine Dolf: They both participated
in a two-year study that included more than 1600 sedentary adults
between the ages of 70 and 89. Dr. Kaycee Sink from Wake
Forest Baptist Medical Center and co-authors divided the
seniors into two groups. Bobby was in the physical activity group.>>Speaker 4: The goal was to get folks to
walk at least 30 minutes at moderate intensity. We also did some lower extremity
strength and some flexibility exercises.>>Catherine Dolf: Instead of exercise, Carol’s
group attended health education seminars on different topics of interest to seniors.>>Speaker 4: We measured how they
were thinking, what their memory and complex processing and language
function at the very start of the study.>>Speaker 5: And I want you to
say the name of each pictures.>>Speaker 3: Acorn. Dominoes.>>Speaker 4: And then we measured it again at
two years after they had been participating.>>Catherine Dolf: The study appears in JAMA,
Journal of the American Medical Association.>>Speaker 4: Both groups preserved their
cognitive function over the course of two years. They stayed the same, which
is really remarkable, because we would have expected
older adults in this age range to have declined at least some over two years.>>Catherine Dolf: Bobby is exercising
almost every day and Carol stays active by spending time with her grandchildren.>>Speaker 4: Older adults should stay
active physically, cognitively and socially. All of those things are important to maintaining
independence and cognitive function as you age.>>Catherine Dolf: Catherine
Dolf, the JAMA Report.
