Multiple choice question?
There are three types of muscle contraction: concentric, isometric, and eccentric.
Concentric: In a concentric contraction, the muscle tension rises to meet the resistance then remains stable as the muscle shortens. During eccentric contraction, the muscle lengthens as the resistance becomes greater than the force the muscle is producing.
Isometric: An isometric exercise is a form of exercise involving the static contraction of a muscle without any visible movement in the angle of the joint.
Eccentric: An eccentric (lengthening) muscle contraction occurs when a force applied to the muscle exceeds the momentary force produced by the muscle itself, resulting in the forced lengthening of the muscle-tendon system while contracting

Explanation:
A person who exhibits sudden paralysis while remaining conscious may be suffering from an episode of cataplexy.
Cataplexy:
While a person is awake, cataplexy is an abrupt loss of muscle tone that causes weakness and a lack of voluntary muscle control. Strong, sudden emotions like laughter, anxiety, rage, tension, or excitement are frequently what set it off.
The reduction of muscular tone experienced during cataplexy is comparable to the natural paralysis of muscle activity experienced during REM sleep. At most a few minutes long, episodes end very immediately on their own. The episodes are frightening, but as long as the person finds a secure location to collapse, they are not harmful. While cataplexy happens once a person is completely awake, sleep paralysis occurs at the borders of sleep.
