What is sarcopenia

 

Sarcopenia is a disease, resulting in a high and progressive loss of mass, strength and muscle functions during aging.

From the age of 30, there is a progressive degeneration of muscle tissue around 3 to 8% per decade, with an acceleration from 50 years. Finally, at the age of 70, we have lost half of our muscle mass in favor of adipose tissue¹.

Various studies estimate that 25% of people over 70 years and 40% over 80 years would be sarcopenic².

Sarcopenia is associated with impairment of vital functions, a weakness, an increased risk of infections, increased risk of falls, a loss of quality of life and becoming dependent³.
