Dynapenia (pronounced dahy-nuh-pē-nē-a, Greek translation for poverty of strength, power, or force) is the loss of muscular strength not caused by neurological or muscular disease that typically is associated with older adults.[1]
Dynapenia is the loss of muscle strength, rather than the loss of muscle mass (sarcopenia). The preservation of muscular strength through the aging process has become increasingly significant with increasing life expectancy in the modern world.
