Frailty can be seen as the weakening of health (defined as the resilience or capacity to cope and to maintain and restore one’s integrity, equilibrium, and sense of well-being in 3 domains: physical, mental, and social). 

Clinically, it has been defined as a "multifactorial syndrome characterized by diminished strength, endurance, and reduced physiologic function that increases an individual’s vulnerability to develop increased dependency and/or death". 

Sarcopenia is the presence of low muscle mass plus low muscle function associated with aging.

Both these entities are strongly linked and the main predictors of negative health outcomes such as falls, disability, hospitalization, and death. They are considered treatable conditions that may be reversible.
