True/False - Only aerobic exercise is needed to battle sarcopenia
False
Example of secondary factor - Disease

Neurological disorders
Diagnosis if muscle strength is normal
No sarcopenia
Two tests used as measurement for skeletal muscle strength
Grip strength
Chair stand test
True/False - Individuals with sarcopenia generally consume less protein those without sarcopenia
True
Example of secondary factor - Malnutrition
Under/over-nutrition
Medication-related anorexia
Diagnosis if muscle quality is low
Sarcopenia confirmed
