WebThe two types of isotonic contraction are concentric (moving the resistance), and eccentric (slowly returning the resistance to a resting state). If a muscle contracts but the bones do not move at all (think about holding your fist in a clench or holding a position in a half squat), we call it an isometric contraction. To put all this together ... WebJul 7, 2024 · Explanation: During muscular contraction, the myosin heads pull the actin filaments toward one another resulting in a shortened sarcomere.
