Sarcopenia

Sarcopenia is the progressive loss of muscle mass and, importantly, strength and physical function that tends to accompany ageing if left unchecked. It's a major contributor to frailty and loss of independence in later life.

It matters because muscle underpins metabolism, mobility, balance and resilience; declining muscle and strength are linked to falls, disability and higher mortality. Much of the decline is not inevitable but driven by inactivity.

In practice, resistance training and adequate protein are the most effective defences, which is why building and maintaining muscle throughout life — not just for aesthetics — is a genuine health priority.
