Disturbance that causes an individual to feel unsteady, or
have a sensation of movement (ex: spinning) when standing or lying down
what can balance disorders be caused by
– Can be caused by certain health conditions (ex: high BP), medications, or a problem in the inner ear or the brain
explain the nutritioanal problems in the elderly
– Elderly sometimes lose their appetites, and do not eat correctly
– They may not feel like eating or are simply lonely. They may not have the energy or are on limited budgets
which individual is more liekely to suffer from sarcopenia
87 idnependant walker or 87 ambularotry with wheelcahri
ambulatory with wheelchair

adls
there are physiological cahanges to the cardiovascular system assocaited with aging, what are the changes in functtion
- ↓ VO2 peak and Max HR
- ↑ Resting and Exercise BP
65 year old men face a decrease in what eprcentage of muscle strength
20%
65 year old women face a decrease in what eprcentage of muscle strength
20-50%
Loss of estrogen
there are physiological changes in the musculosketal system associated with aging, what are the chagnes in function
↓ Musc Strength, Flexibility,
Balance and Muscle Mass
in the nervous system, is there a decrease in nerve condution>
yes, in aging, there is a decrease in nerve conduction by 20% because of neurolnal degenration
why is there a decrease in nerve condution by 20% in aging
because of neuoral degeneration
there are physiological changes in the nervous system associated with aging, what are the chagnes in function
- ↑ Time of reaction (↓ conduction speed by 20%)
- ↓ Sensory System
in aging, is there a decrease in basal metabolic rate?
yes
since there is a decrease in basal metabolic rate in aging, what does tthat icrease the risk of
icnrease the risk of diabettes
there are physiological changes in the metabolic system associated with aging, what are the chagnes in function
↓ Basal Metabolic Rate and Lean Body Mass
↑ Body Fat
Which of these variables has showed the strongest correlation with the risk of falls in older adults?
a) ↑ time of reaction b) ↓ musc strength c) ↓ flexibility d) ↓VO2 peak
increase time of reaction
what is the variable that showed the sttrongest correlationn with the risk of falls in older adults
increase time of reaction
Which training mode can
decrease the risk of reaching the disability threshold?
strenght training
throughout life, there is a range of muscle mass and strength between indivdiausl, but where do you not want to be under
the disability threshold
if you are below the disability threshold, you become dependatn in what
