Sample Answer

During the running stride, the hamstrings and quadriceps demonstrate the antagonistic relationship between muscle groups.
As the leg drives forward, the quadriceps contract concentrically to extend the knee while the hamstrings undergo eccentric contraction to control the movement.
During the recovery phase, the hamstrings contract concentrically to initiate knee flexion while the quadriceps lengthen eccentrically.
This alternating pattern of concentric and eccentric contractions allows for controlled movement and efficient force production throughout the running stride.
