23
Q

isotonic contraction

A

muscle contracts to create movemtn

24
Q

concentric contraction

A

when muscle shortens under tension

25
Q

eccentric contraction

A

when the muscle lengthens under tension (downward phase of movements)

26
Q

isometric contraction

A

when the muscle contracts without lengthening or shortening

-no movement occurs-
