Slow gait speed over 4m
R/Fs for sarcopenia?
Lack of exercise
Low protein diet
Exercise, dietary supplementation, Vit D
Risks for falls in the elderly?

Definition of sarcopenia?
Progressive generalised loss of skeletal muscle mass and strength with age
Factors that account for the maintenance of muscle mass?
Anabolic hormones e.g. testosterone
Growth factors e.g. GH
Factors that account for the reduction in muscle mass in sarcopenia?
Catabolic hormones e.g. Glucagon, steroids
Inflammatory mediators e.g. cytokines
Changes to muscle tissue with age?
Decline in both muscle fibre size and number
Single muscle fibre intrinsic force is decreased
Definition of frailty?
Increased vulnerability to stressors associated with a decline in physical and psychological reserves
Consequences of sarcopenia?
Disability and poor mobility
Falls and fractures
Reduced quality of life
Features of a diet that may prevent sarcopenia?
Higher antioxidant status
High Fish oil consumption
Greater fruit and vegetables
