To
determine
whether
10
weeks
of
whole-body
vibration
(WBV)
training
has
a
significant
effect
on
strength,
muscle
mass,
muscle
power,
and
mobility
in
older
women,
26
subjects
were
randomly
assigned
to
a
WBV
training
group
(n=13;
mean
age
79
years)
and
a
control
(CON)
group
(n=13;
mean
age
76
years).
Maximal
voluntary
isometric
contraction
(MVIC)
increased
38.8%
in
the
WBV
group,
without
changes
in
the
CON
group.
Electromyographic
activity
of
the
vastus
medialis
(VM),
the
vastus
lateralis,
and
the
biceps
femoris
(BF)
did
not
change
in
either
group.
Thigh
muscle
cross-sectional
area
increased
significantly
after
training
in
VM
(8.7%)
and
BF
(15.5%).
Muscle
power
at
20%,
40%,
and
60%
MVIC
decreased
from
pre-test
to
post-test
in
the
CON
group;
however,
WBV
training
prevented
the
decrease
in
the
WBV
group.
Consequently,
mobility,
measured
by
the
Timed
Up
and
Go
test,
increased
significantly after training (9.0%) only in the WBV group.
Ten
weeks
of
lower
limb
WBV
training
in
older
women
produces
a
significant
increase
in
muscle
strength
induced
by
thigh
muscle
hypertrophy,
with
no
change
in
muscle
power.
The
adaptations
to
WBV
found
in
the
present
study
may
be of use in counteracting the loss of muscle strength and mobility associated with age-induced sarcopenia.
