AGING AND THE MUSCULAR SYSTEM
With age,
muscle cells die and are replaced by fibrous connective tissue or by fat.
Regular exercise, however, delays atrophy of muscles. Although muscles become
slower to contract and their maximal strength de-creases, exercise can maintain
muscle functioning at a level that meets whatever a person needs for daily
activities. The lifting of small weights is recom-mended as exercise for
elderly people, women as well as men. Such exercise also benefits the
cardiovascular, respiratory, and skeletal systems.
The loss of
muscle fibers also contributes to a loss of proprioception, because the brain
is getting less information about where and how the body is posi-tioned. The
loss of muscle sense contributes to unsteadiness in elderly people and to an
impaired sense of balance, which in turn may lead to a fall. Simple awareness
of this may help an elderly person prevent such accidents.
