2 multiple choice 1 point
what are the hamstring muscles likely doing as the leg goes from mid swing into terminal swing?
eccentrically controlling (slowing) knee extension
concentrically developing knee flexion
eccentrically controlling (slowing) knee flexion
concentrically developing knee extension
clear my selection

Explanation:

The hamstring muscles are responsible for knee flexion. When the leg goes from mid - swing into terminal swing, the movement of the knee is being controlled. Eccentric contraction occurs when a muscle lengthens while still under tension. In this case, as the leg moves into terminal swing, the hamstring muscles are eccentrically controlling (slowing) knee flexion to ensure a smooth and controlled movement. Concentric contraction (where the muscle shortens) for knee flexion would be more relevant in initiating flexion rather than controlling it during this phase. Knee extension is mainly the function of the quadriceps.

Answer:

Eccentrically controlling (slowing) knee flexion
