Q

empty endfeel

A

pain

Q

rubbery endfeel

A

muscle spasm

Q

isometric contractions

A

no change in muscle length

Q

isotonic contractions - types and what

A

concentric and eccentric

change in muscle length while the force or tension remain the same

Q

what is a concentric muscle contraction

A

the muscle length shortens

EX: lifting yourself up against gravity

Q

what is eccentric muscle contraction

A

the muscle length gets longer

EX: lowering yourself against gravity

Q

what is a isokinetic contraction

A

constant velocity muscle contraction that requires equitment

Q

A
