The hamstring (back / dorsal side of the thigh)
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.
Quadricepts
Quadriceps muscle or thigh muscle.
A bruise on your quadriceps muscle, which is the large muscle in your thigh.
No it is not true, the antagonist muscle to the biceps is the triceps. You have to think of what muscles will have to release in order to allow contraction, another example would be when the quadriceps contract, your hamstrings must release otherwise the work of the muscles would contradict one another.
In hockey, the antagonist muscles that are commonly engaged include the hamstrings, which oppose the action of the quadriceps during skating strides. When the quadriceps contract to extend the knee for pushing off, the hamstrings help control and stabilize the movement, ensuring proper technique and balance. Additionally, the gluteus medius acts as an antagonist to the hip flexors, aiding in lateral movements and stability on the ice.
antagonist muscle
A antagonist muscle is a muscle that opposes the action of another muscle. The Triceps Brachii is the antagonist of the Biceps Brachii.
in the arm: bicep contracts (agonist) triceps relax (antagonist) in the leg: hamstrings contract (agonist) quadriceps relaxes (antagonist) remember the agonist is the muscle "agonising" to do the work - like pulling the joint.
