European consensus
“Sarcopenia with limited mobility” is defined as a person with muscle loss whose walking speed is equal to or less than 1
m/s or who walks less than 400 m during a 6-minute walk, and who has a lean appendicular mass corrected for height
squared of 2 standard deviations or more below the mean of healthy persons between 20 and 30 years of age of the same ethnic group.
Morley et al. JAMDA 2011
International consensus
Sarcopenia interrelates with
organ systems.
Urgent need for a consensus
definition of sarcopenia.

Sarcopenia interrelates with
organ systems.
Urgent need for a consensus
definition of sarcopenia.
Sarcopenia associates strongly
with detrimental outcome in
cancer patients.
Targeted intervention!
