From the time you are born to around the time you turn 30, your muscles grow larger and stronger. But at some point in your 30s, you start to lose muscle mass and function. The cause is age-related or sarcopenia with aging.
Sarcopenia typically happens faster around age 75. But it may also speed up as early as 65 or as late as 80. It’s a factor in frailty and the likelihood of falls and in older adults.
Symptoms can include weakness and loss of stamina, which can interfere with physical activity. Reduced activity further shrinks muscle mass.
If you or someone you know has sarcopenia, they may qualify for a paid research study at ACR. Please see below for ACR locations that are currently enrolling for sarcopenia studies.
