sarcopenia

   Also found in: Wikipedia 0.01 sec.
sarcopenia /sar·co·pe·nia/ (sahr″ko-pe´ne-ah) age-related reduction in skeletal muscle mass in the elderly.
sarcopenia
[-pē′nē·ə]
Etymology: Gk, sarx, flesh, penia, poverty
a loss of skeletal muscle mass that may accompany aging. Studies indicate that the loss of skeletal muscle for the average normally healthy person amounts to about 20% between about 30 and 70 years of age. The loss may accelerate as aging progresses. The muscle is replaced by fat, usually in a subtle way that is not noticed by the individual, as by padding areas of muscle loss with extra fat. Muscle-strengthening and muscle-building exercises can prevent or reverse much of this problem.
