What is a concentric contraction?

muscle shortens

what is an eccentric contraction?

the muscle lengthens under tension

What is an isometric contraction?

muscle contracts but does not change length

what is a closed chain movement?

movement concurring when the distal segment of the joint is fixed in space (ex: push up because hands are fixed on the ground)

what is an open chain movement?

movement occurring when the distal segment of a joint moves in space
