Physiology of Aging: Theories, VO2max and Muscle Decline
Cards in this deck (33)
- 1PathologericThis is considered pathological; not a predestined part of aging
- 225-30 yearsThis is the age at which most physiological declines begin
- 3Rate of Living TheoryTheory that states that the faster an organism's metabolism, the shorter its lifespan
- 4Accumulation TheoryTheory suggests a functional decline w/ aging resulting from the accumulation of biproducts from cellular metabolism
- 570 yearsThe age at which a decrease in weight tends to occur
- 6DeclinesThis is what happens to RMR w/ older age
- 7go down/declineLoss in muscle mass causes RMR to do this
- 8Disease BurdenHigher RMR in older sedentary adults is indicative of this
- 9Oxidative StressThis may result from chronic elevations in oxidative/aerobic metabolism
- 10SOD, GPX, catalaseThis is an example of an endogenous antioxidant
- 115% per decadeThe rate in decline of VO2max that occurs with older age in highly active individuals
- 12Walking/Exercise EconomyThe measure of the amount of energy required (metabolic cost) to travel 1.5 mph
- 13AerobicReliance on this energy system predominates w/ older age
- 14SDHThe activity of this metabolic enzyme improves w/ AEX even in older adults
- 15ReducedWhat happens to muscle glycogen levels with older age
- 1610%The % decline in muscle mass that occurs by 50 years old in inactive individuals
- 17Type IOlder age results in greater shift to this fiber type
- 18Low Muscle QualityInfiltration of IMAT results in this
- 1960-80 yearsMajor decrements in muscle fiber size occur within this age range
- 20Loss of alpha motor unitsloss of total muscle fibers that occurs w/ older age is closely related to this
- 21FNIHDefinition of sarcopenia that includes ALM/BMI and low muscle strength
- 22SPPBThis test for physical function includes balance, gait speed and chair stand
- 230.3 W/kgThe minimum muscle power needed to rise from a chair
- 24greater or equal to 15sThe time in four-square step test that is indicative of greater disability
- 25<20kgAccording to the EWGSOP, this is the cutoff for handgrip strength in women
- 26Skeletal Muscle CapillariesThis is necessary for adequate perfusion of skeletal muscle
- 27greater than or equal to 12sThis time in the TUG test is indicative of greater fall risk
- 28CalciumThis mineral adds strength to the bone and hardens the framework
- 29RigidityThis feature of bone that allows for movement
- 30Onset of symptoms occurs ~10 years earlier in this type of arthritisp
- 31OsteoclastsThese cells break down and remove old/damaged bone
- 32below -2.5The T-score associated w/ osteoporosis
- 33Weight bearing (high loading)What type of exercise is best for improving BMD?
