While each of these factors is distinct, they actually combine to produce the age-related loss of muscle coordination and mass that we call sarcopenia.

Cigarette smoking has also been associated with sarcopenia, the age-related loss of muscle mass and strength.

Presbyopia is the age-related loss of accommodation, which is marked by the inability of the eye to focus on nearby objects.

But it is more than 10 times the normal age-related annual loss.

And strength training helps delay age-related loss of muscle mass and strength.

The empathic model is a technique used to simulate age-related sensory losses to give designers personal experience with how their product performs for users.

The rate at which they are lost correlates well with the age-related loss in touch sensitivity for small probes (Thornbury and Mistretta, 1981).

There is also a gradual onset of muscle weakness as a result of sarcopenia - the age-related loss of skeletal muscle.

Because polio survivors have already lost a considerable number of motor neurons, further age-related loss of neurons may contribute substantially to new muscle weakness.

A study conducted on rats who, like humans, suffer from an age-related loss of memory were tested on how choline affected memory.
