The hamstring muscle group (biceps femoris, semitendonosis, semimembranosis) are the antagonists to the quadricep group.
The antagonist muscle in the flexion of the knee is the quadriceps muscle group. When the knee is being flexed, the quadriceps relax to allow the hamstrings to contract and bring about the flexion movement.
