Quizplus · Accepted Answer

An isometric contraction is defined as a constant contraction with no change in joint angle and no change in muscle length. Imagine an arm wrestling match where the opponents are at an equal standstill, creating resistance while still engaged in the match. There is no movement, but each opponent's muscle groups are still fully contracted. Another example would be performing a push up and stopping when your arms are fully extended and you are holding up your own weight.
