Aging Flashcards
(30 cards)
body movement produced by muscle action that increases energy expenditure
physical activity
planned, structured, repetitive and purposeful physical activity
exercise
attributes related to how well one performs physical activity
physical fitness
physical, social and mental well being; not just absence of disease
health
components of physical fitness associated with some aspect of good health and/or disease prevention
health related physical fitness
length of life
longevity
Successful aging includes what 4 components?
physical health
spirituality
emotional/educational health
social satisfaction
considers the overall length of life based on mortality data without considered quality of life
life expectancy
how many years of life you have left is considered?
HALE- healthy life expectancy
men and women attain highest strength levels between what ages?
20 to 40
concentric strength decline?
slowly at first and then more rapidly after middle age
eccentric strength declines?
at a later age and progresses more slowly than concentric strength
arm strength deteriorates ?
slower than leg strength
primary cause of reduced strength between ages 25 and 80 relates to a 40-50%…..?
reduction in muscle mass from muscle fiber atrophy and loss of motor units
**applies to everyone, even healthy ppl
4 parts that should be included in a regular training program
aerobic
strength
flexibility
balance training
neural function with aging
decline in spinal cord axon number and nerve conduction velocity
What happens to heart rate with age?
declines
Around age 35, what happens to VO2 max?
declines at a non-linear rate that accelerates after 45
T or F: Physical activity does NOT entirely offset aging’s effect on VO2max even when adjusting for muscle mass quantity.
TRUE
Stats for people with high BP who exercised regularly
reduced death rate by 1/2
Do kids have a higher or lower VO2 max than adults?
lower
Children cant generate high levels of what during maximal exercise?
blood lactate
For exercise testing consideration: testing protocol should start with what?
workload at less or equal to 3 METs
small increments .5-1.0 METs
All exercise prescriptions should include what 4 components?
aerobic
muscle strengthening
flexibility
balance
