Being old may not necessarily mean being frail in the future thanks to new research on why muscles weaken with age.
The work could potentially lead to a pill that reverses muscle loss in the elderly.
An experimental drug called S107 has been shown to strengthen two-year-old mice with an equivalent human age of 70. A similar drug is now undergoing clinical trials for the treatment of heart failure, say scientists.
Skeletal muscles naturally wither and weaken with age. The effect, which begins to appear at around the age of 40, is a major cause of disability in the elderly.
