Q

what is isotonic contraction?

A

where the muscle contracts and changes length which will create movement at the joint

29
Q

what are the two types of isotonic contraction?

A

concentric + eccentric

30
Q

what is concentric contraction?

A

contracts and shortens while producing tension

31
Q

what is eccentric contraction?

A

contracts and lengthens while producing tension

32
Q

what is isometric contraction?

A

where the muscle contracts creating a force but no movement takes place
