Geriatric research

​Loss of muscle strength and functional performance occur with increasing age, which is why independent living becomes increasingly difficult in older age. Because of this, older people are less resistant to what younger people perceive as a minor bodily stress – such as a period with influenza – which often causes a further loss of muscle strength due to inactivity or bed rest. An acute loss of muscle strength may be particularly damaging in older people with limited reserve-capacity in muscle strength and functional performance, and may result in acute hospitalization.
