Question

What is the primary function of the quadriceps during midstance?

A. Concentrically flex the knee for upcoming swing phase
B. Eccentrically controls knee flexion
C. Concentrically extend the knee to support body weight
D. Eccentrically control hip flexion

Answer 1

The primary function of the quadriceps during midstance is to concentrically extend the knee to support body weight.

Step-by-step explanation:

The primary function of the quadriceps during midstance is to concentrically extend the knee to support body weight. At this phase of the gait cycle, the quadriceps contract to extend the knee joint and provide stability while distributing body weight. This action helps maintain balance and prepare for the subsequent swing phase.
