Questão 21

TEXTO:

     Since the early 21st century, numerous studies
have shown how aerobic exercise promotes the
generation of new brain cells and white matter
integrity in people who exercise regularly. However,
[5] there’s still a lot of uncertainty about the exact “doseresponse” related to how much time people should
spend being physically active in their daily lives. And
nobody is certain about what intensity (easy, moderate,
vigorous, or intense) of physical exercise is ideal
[10] for optimizing brain structure and functional connectivity
across a lifespan.

    A recent study, conducted by researchers in
California and in Japan, shows that a single 10-minute
bout of very light physical activity can increase the
[15] connectivity between brain regions linked to memory
formation and storage. What makes this study unique
is that the researchers have demonstrated a more
immediate impact related to the strengthening of
communication lines between memory-focused parts
[20] of the brain after a single 10-minute bout of light activity
that wasn’t aerobic. 

     For this study, the researchers recruited 36 healthy
young adults and had them perform 10 minutes of very
easy physical movements such as tai $\chi$ or gentle yoga.
[25] Immediately after the brief session of physical
movement was completed, each person’s brain was
scanned using high-resolution functional magnetic
resonance imaging (fMRI). In comparison to a control
group that hadn’t done any physical activity, those who
[30] had gently moved their bodies for 10 minutes prior to
the brain scan showed better connectivity between the
hippocampal dentate gyrus as well as cortical areas
linked to detailed memory processing and storage. “The
hippocampus is critical for the creation of

      new memories; it’s one of the first regions of the brain
to deteriorate as we get older — and much more
severely in Alzheimer’s disease,”they said.

According to the text, fill in the blanks with T (True) or F (False). Previous research has shown that aerobics exercise

( ) can damage our brain’s white matter.

( ) kill newly-generated harmful brain cells.

( ) contributes to the growth of a few brain regions.

( ) improves the wholeness of the brain white matter.
