How Exercise
and Beta-Glucan
Help the Immune
System
You may
enhance your
body's natural
resistance to
infection with
moderate
exercise, such
as speed
walking,
jogging, and aerobics. This
is due to that
fact that this
kind of
physical
activity
activates the
release of immunostimulatory
factors, such as
growth hormones,
cytokines, and
prolactin, which
in turn
activates
various
populations of
immune cells.
Exercise
sessions of
moderate
duration (under
60 minutes) have
been associated
with enhanced
activity within
the immune
system. This
applies to many
different immune
parameters,
including
oxidative
metabolism,
mactophage
chemotaxis, and
phagocytic
activities, as
well as
increased
natural killer
cell activity.
The nature of
these cells'
phagocytic,
cytotoxic, and
intracellular
killing
capacities
constitutes and
important part
of the body's
first line
immune defense.
Another immune
boosting method
that more and
more people have
used over the
past few years
to boost their
immune functions
is to take a
Beta Glucan oat
fiber
supplement.
These
supplements
contain ß-Glucans
(polysaccharides
derived from the
cell walls of
yeast, algae,
fungi, and
oats), which
have shown been
to enhance both
specific and
non-specific
immune
functions, yet
have received
little attention
so far in the
field of
immunology. Beta
Glucan directly
stimulates
macrophage,
neutrophil, and
natural killer
cells via ß-Glucan
specific
receptor sites.
When this
reaction occurs,
a cascade of
immune defenses
are set off,
which protect
the organism
from a wide
range of viral,
bacterial, and
fungal
challenges. The
exact mechanisms
that occur
depend at least
partially on the
route of
administration.
For example,
much of the
protection
achieved from
oral
administration
results
primarily from
certain effects
of ingestion.
