As you age,
it becomes harder to keep your muscles healthy. They get smaller,
which decreases strength and increases the likelihood of falls
and fractures. New research is showing how this happens, and what
to do about it.
have already shown that when older people eat, they cannot make
muscle as fast as the young. Now they've found that the suppression
of muscle breakdown is blunted with age. This may explain the
ongoing loss of muscle in older people when they eat they
don't build enough muscle, and in addition, their insulin fails
to shut down the muscle breakdown that rises between meals and
weight training may "rejuvenate" muscle blood flow and help retain
muscle for older people.
