An isometric contraction generates increasing muscle tension without producing which of the following?

1. Isometric contractions occur when a load is too heavy for the muscle to move. 2. Sarcomeres still activate and shorten to a point, generating ever-increasing tension, and cross-bridges still form and consume ATP. 3. However, because the force produced cannot overcome the load's resistance, the angle of the skeletal joint does not change. 4. Cross-bridge formation, sarcomere activation, and ATP use all still occur in an isometric contraction, so none of these three is the thing that is absent. _Source: OpenStax Anatomy and Physiology (CC BY 4.0), Ch 10 "Muscle Tissue", section 10.4, p. 421_
