Biological-age tests are flooding the longevity scene, but the rulers we use to measure aging — and the muscle loss that comes with it — are getting a hard second look.
Two new papers reframe age-related muscle loss as a downstream effect of chronic inflammation, immune aging, and a restless gut. Protein shakes alone won't cut it.
A 13,422-person analysis hints the brain-friendly eating pattern may also help older adults hold onto muscle and physical function.
A new mechanistic review argues that after 50, the cardiovascular system and the skeletal muscle system age as one. Protecting muscle, in other words, may be vascular medicine in disguise.
New molecular and longitudinal research suggests the slide in strength begins decades before frailty — and that nerves and inflammation, not just muscle, set the pace.
A new systematic review reframes age-related strength loss as a problem of failing wires, not shrinking cables — and it changes what screening and training after 60 should look like.
A 2025 review reframes sarcopenia as a modifiable condition — and grades which interventions actually move the needle on muscle mass, fiber loss, and motor unit decline.
Two new studies reframe the conversation around metabolic health in later life — pointing to skeletal muscle, mitochondria, and medication choice as the quiet variables that matter.
A long-running Taiwanese cohort took a closer look at osteosarcopenia — losing bone and muscle at the same time — and the findings are more nuanced than the headlines suggest.
