Intro 0:30 As you age, you move less. 2:40 Aging is associated with changes in muscle metabolism and a decline in functional capacity. 3:45 There is an increase in insulin resistance as you age.  6:00 Aging is associated with declines in skeletal muscle mass, sarcopenia and dynapenia. 6:50 Lean muscle loss occurs at .7 to .8%/year during your 70s.  7:30 Rate of muscle loss is greater in legs and lower extremities as you age. 8:10 Hand grip strength reflects your habits. 9:45 Increase your physical activity as you get older. 10:15 You preferentially lose fast twitch muscle fibers as you age. 13:10 Increase protein intake as you get older. 16:20 Do resistance training 3 to 4 days per week and walk 10,000 to 12,000 steps on most days. 16:47 You can overcome the age-associated declines in muscle protein synthesis and changes in muscle fiber type.
