4.2.2

Outline the types of muscle contraction.

Isotonic: increase in load on the muscles (concentric and eccentric muscle contractions).

Isometric: Muscles generates force without changing length (ex: plank).

Isokinetic: the speed of the movement is fixed and the resistance varies with force exerted (needs special equipment).

Concentric: muscle is shortening during contraction.


Eccentric: muscle is contracting while lengthening.
