POSTURAL STRAIN
In
a
relaxed
state,
muscles
do
not
require
much
blood
and
the
supply
of
blood
matches
the
muscle's
demands.
When
the
muscles
are
involved
in
rhythmic
contractions,
such
as
during
walking,
running
or
cycling,
the
blood
circulation
to
the
muscles
increases
and
matches
the
increased
demands
of
the
muscles
(unless
the
activity
is
very
intense).
When
a
muscle
is
contracted
for
a
prolonged
duration,
the
blood
supply
to
the
muscle
is
restricted
due
to
continuous
compression
of
the
blood
vessels
by
the
muscle.
At
the
same
time,
the
muscle's
requirement
for
oxygen
has
increased
due
to
the
contraction,
so
the
blood
supply
to
the
muscles
is
not
matching the muscles demands.
When
this
chronic,
static
muscle
contraction
occurs,
your
body
responds
by
sending
cells
to
the
area
that
will
lay
down
fibrous
connective
tissue
within
the
muscle
to
help
re-enforce
and
support
the
muscle.
Over
a
long
period
of
time,
the
muscle
slowly
becomes
weaker,
more
”leathery”,
and
painful
knots or trigger points will develop in the muscle.
The
most
common
cause
of
static
muscle
contraction
is
poor
posture.
Poor
posture
can
occur
while
standing,
sitting,
sleeping,
playing
sports,
working,
or
doing
hobbies.
The
most
effective
approach
is
prevention,
which
can
be
addressed
by
the individual or the activity.
Individual interventions may include:
•
Postural education for sitting, standing and sleeping.
•
Stretching and strengthening exercises.
•
Nutritional advice.
•
Advice on technique and biomechanics of the activity.
