Sarc/o/penia is a medical term built from two word parts:
- sarc – word root for flesh or connective tissue
- -penia – suffix for [abnormal] reduction
The first known use of sarcopenia was in 1991.
The literal translation (finding the definition of a term by using the word parts) of sarcopenia is a reduction of connective tissue. Skeletal muscles are connective tissue, and since the reduction, or loss, is age-related, sarcopenia is often defined as age-related muscle loss.
