Which of the following is used to determine the pulling strength of a pennate muscle on its attachment?

Question

Quizplus · Accepted Answer

The pulling strength of a pennate muscle on its attachment is determined by the pennation angle, which is the angle between the muscle fibers and the line of pull of the muscle. A larger pennation angle results in greater cross-sectional area and therefore greater force production, while a smaller pennation angle results in greater muscle fiber length and therefore greater shortening velocity. Therefore, the pennation angle is an important biomechanical factor in determining the force-generating capacity of pennate muscles.
