UAMS Study Shows Bed Rest Speeds Muscle Deterioration in Elderly

LITTLE ROCK (AP) - A new study by researchers at the University of Arkansas for Medical Sciences shows that elderly adults who take bed rest during hospitalization lose a substantial amount of muscle tissue from their inactivity.

The study, printed in yesterday's issue of the Journal of the American Medical Association, showed that inactivity led to a large decrease of a muscle cell's ability to make a necessary protein. A research team led by William J. Evans found its 12 study participants lost 30 percent of their muscle cells' protein-making ability.

Evans says the researchers also found the bed rest likely caused an increase in insulin resistance, which further ratcheted down the protein production rate.

Evans says the team will examine different strategies for preventing muscle loss. Those potential treatments included nutritional supplements, exercise and the use of insulin sensitizers.
