Which of the following would result in increased active muscle tension if the task required the muscle to produce greater torque/tension?

a. Increased firing rate of the activated motor units
b. Decreased number of motor units activated
c. Increased amount of perimysium and endomysium
d. Decreased number of cross-bridges formed

ANS: A
Active tension occurs as a result of several factors, including the number of motor units recruited,
the fiber type of the motor units recruited, the type of contraction being performed, and the
frequency of motor unit firing.
