Aging Flashcards
Age Related Changes
Bones brittle
Cartilage thinner
Epithelium thinner
More fragile
Overall decline
Osteoporosis
Decrease bone density
Highest at risk = female
Health promotion: movement, weight bearing exercises, balance
Arthritis
Inflammation of joint
Wear and tear
Susceptible joint: knee
Increase resistance, mobility, balance/ stability exercises
Variety is key
Muscular System
Smaller muscle fibers
Ability to recovery decreased
Nervous System
Dementia is a result
Reduced brain size and blood flow
Decrease senses
Cardiovascular system
Blood decrease
Max cardiac output decrease
Decrease blood vessels
Increased PA can reverse age related heart changes
Respiratory system
Decreased efficiency
Regular exercise substantially slows decline
Fall risk
Leading cause to injury
More in women than men
Eccentric strength is key to absorbing fall
Fall prevention
Muscle strength
Endurance
Balance
Main 3 things aging population should work on
