Exercise and Skeletal Muscle Flashcards
1
Q
muscle hypertrophy
A
- building muscle increase fiber size but not number of fibers
- results from repetitive, exhaustive stimulation of muscle
2
Q
muscle atrophy
A
reduced stimulation results in reduced muscle size, tone, and power due to lack of use
3
Q
muscle tone
A
some muscle fibers activated and some in resting state
4
Q
isometric contraction
A
muscle length is constant
5
Q
isotonic contraction
A
muscle length is shortening
6
Q
concentric contraction
A
muscle length is shortening
7
Q
agonist
A
prime mover, muscle that does most of the work in an area
8
Q
antagonist
A
muscle that opposes the agonist
9
Q
