WebThe greater force capacity during lengthening contractions is attributable to the stretching of incompletely activated sarcomeres, an increase in cross-bridge force, a more rapid reattachment phase, and—most importantly—the engagement of a third contractile protein known as titin. The force contributed by titin increases during the ... WebJan 17, 2024 · Isotonic contractions generate force by changing the length of the muscle and can be concentric contractions or eccentric contractions. A concentric contraction causes muscles to shorten, thereby generating force. Eccentric contractions cause muscles to elongate in response to a greater opposing force.
