Frailty, sarcopenia, and cachexia: loss of muscle mass in the elderly. Complex metabolic syndrome associated with underlying illness and characterized by loss of muscle with or without loss of fat. Age-related loss of muscle mass and function that leads to disability. Loss of muscle due to bed rest. Rda for protein inadequate for nitrogen balance. Role of exercise and activity in treatment of sarcopenia. Strength gains were greatest in the group that strength trained and received a protein- calorie supplement. Before intervention, measure muscle mass by whole-body potassium. Spontaneous activity = what you do in the course of a day. Quarter stay in hospital for a year. How far can you walk in six minutes.
