22
highest strength levels are achieved during this age range
20-40
concentric strength of muscle groups decline slowly then more quickly after blank
middle age
blank strength declines at a later age than blank strength
eccentric, concentric
blank stregnth decreases more slowly than blank
arm, leg
a normal, continuous process that involves motor endplate repair and reconstruction, gradually deteriorates in old age
motor unit remodeling
denervation of muscles with age causes blank
muscle atrophy

increase in the number of blank fibers with aging
type 1
muscle size decreases at this age
30
muscle size decreases by about blank percent between 30 and 50
10
aging leads to a blank decline in the spinal cord axons number and a blank percent decline in nerve conduction velocity
40, 10
physical activity blanks the effects of aging on muscles and neural function
slows
glucose tolerance decreases with age which can lead to blank

thyrotropin, metabolic
hormonal changes can result in blank with age
somatopause, menopause, andropause
