Age - Lecture 3 Flashcards
@ birth muscle accounts for
25% of BW
from infancy to puberty
muscle fiber size and muscle mass increase
muscle mass and strength is slightly greater in
boys
10%
when does hypertrophy become present
puberty
pre-adolescence has improved
muscle strength and motor performance
body comp
pre-adolescence has an increased sense of
well being
pre-adolescence bring a
positive attitude towards fitness
what training is acceptable with pre-adolescence
moderate resistance training
heavy resistance training should be avoided
focus on technique
adolescence includes
rapid acceleration of muscle mass
gender differences occur
training for adolescence
avoid heavy lifting and unilateral loading
general strength training is recommended
resistance training –> adolescence
results in significant strength gains
in early and middle adulthood
muscle mass peaks
decrease in muscle mass can begin as early as 25
early and middle adulthood –> muscle mass BW
40% of total BW
men having more than women
improvements in physical activity –> early and middle adulthood
modest
in late adulthood
strength declines
as much as 15-20% per decade
during the 6th and 7th decades
by 80 y/o…
strength is 50% of peak
how does atrophy occur –> late adulthood
of type 2 fibers
speed of muscle contraction –> late adulthood
slows
in late adulthood there is a loss of
flexibility
fxnal skill
endurance
in advanced age there is still possibility of
reverse muscular weakness
advanced age requires
lower stimuli for strength gains
what is needed with advanced age
longer recovery
training considerations for advanced age
power and strength
benefits for all ages
neural benefits
skeletal muscle benefits
connective tissue benefits
vascular and metabolic benefits
body comp
“feeling good” sensation
