How the concept was born
In 1988 Tufts University researcher Irwin Rosenberg pointed out that muscle loss with age was hugely consequential yet had no name, so he proposed sarcopenia, from the Greek for "flesh" and "poverty." Early definitions focused on muscle mass alone, but evidence that strength matters more led the European Working Group on Sarcopenia in Older People (EWGSOP) to fold in strength and function in 2010; its 2019 revision made low grip strength the starting point. Sarcopenia got its own ICD-10-CM code (M62.84) in 2016, and an Asian working group set body-size-adjusted cutoffs.
Diagnosis and risks
Under EWGSOP2, grip strength below 27 kg for men or 16 kg for women, or taking more than 15 seconds to rise from a chair five times, flags probable sarcopenia; low muscle mass on a DEXA or body-composition scan confirms it. A quick home screen is the "finger-ring test": if your thumbs and index fingers easily encircle the thickest part of your calf, take note. Muscle declines roughly 1% a year after 30 and faster after 70. Sarcopenia raises the risk of falls, fractures, osteoporosis, worsening diabetes, hospitalization, and death.
Prevention and treatment
No drug is approved yet; resistance training is the proven treatment. Squats, sit-to-stands, and band work two to three times a week, plus walking, make a real difference. Older adults do best with about 1.0–1.2 grams of protein per kilogram of body weight daily, spread across meals, with leucine-rich foods like milk, eggs, and fish. Correct low vitamin D, and consider creatine alongside lifting. More muscle also raises your resting metabolic rate.

FAQ
- Can younger people get sarcopenia?
- Yes—long periods of inactivity, crash dieting, or chronic illness can cause it early.
- Is walking enough?
- Walking helps, but you need strength training to rebuild muscle.
