The force that a muscle fiber produces results from many thousands of myosin cross-bridges binding to actin filaments over time. Given this, which statement(s) are correct. Choose all that apply.
A. The net force produced by the fiber represents the summation of cross-bridge forces across the thickness and length of sarcomeres within the muscle fiber.
B. More cross-bridges are associated with greater force generated by the sarcomere.
C. Variation in cross-bridge force could be assessed by measuring the standard deviation of peak individual cross-bridge forces.
D. All of the answer options are correct.
