Sarcopenia – why do our muscles become weaker when we age?

Karolina RygielDr Karolina Rygiel

The process of muscle wasting and loss of strength which progresses with advancing age is called sarcopenia. It is a serious condition as it is estimated that between the ages of 20 and 80 years selected skeletal muscles lose up to 40% of their mass resulting in restricted mobility for affected people. We are trying to understand the mechanisms behind this process by looking at the muscle itself, the nervous system which stimulates the muscle, and the connection between the nerves and the muscle cells.
