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

well being
pre-adolescence bring a

focus on technique

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
