The antagonists would be those muscles that cause knee flexion. Hamstrings (biceps femoris, semimembranosus, semitendonosis) are the primary knee flexors, and would thus be antagonists to knee extension.
The prime mover for knee flexion is biceps femoris, semimembranosus, and semitendinosus. The prime mover for knee extension is the Quadriceps â?? vastus lateralis, vastus medialis, vastus intermedius, and rectus femoris
Hip and knee extension primarily involves the gluteus maximus and the hamstring muscles for hip extension, while the quadriceps are the primary muscles responsible for knee extension. The gluteus maximus helps to extend the hip joint, while the hamstrings facilitate both hip extension and knee flexion. The quadriceps, particularly the rectus femoris, vastus lateralis, vastus medialis, and vastus intermedius, are crucial for straightening the knee during extension. Together, these muscle groups work to perform movements such as standing up, walking, and running.

When kicking a ball, the primary agonist muscle is the quadriceps, which extends the knee to propel the leg forward. The hamstrings act as the antagonist muscles, controlling the movement and preventing hyperextension of the knee. Additionally, the hip flexors assist in lifting the leg, while the gluteal muscles stabilize the hip during the kick.
Sartorius.
False. The quadriceps muscle is primarily responsible for extending the knee, not flexing it. The muscles that flex the knee are mainly the hamstrings.
extensorThe triceps brachii is an extensor. It is the large muscle on the back of the arm and is primarily the muscle used for extension of the elbow joint or straightening of the arm. The triceps is also an antagonist of the biceps and the brachialis muscles.ExtensorsTriceps is not a flexor. It is extensor of the elbow joint.
The antagonist muscle used in a leg curl is the quadriceps, located at the front of the thigh. During a leg curl, the hamstrings contract to flex the knee, while the quadriceps must relax and lengthen to allow this movement. This reciprocal inhibition helps facilitate smooth and controlled leg movements.
quadricepts are the muscle on the front of your leg above the knee. they are used in football, rugby etc
Stretching an antagonist muscle through the tension of the agonist muscle is a technique often used in proprioceptive neuromuscular facilitation (PNF) stretching. In this method, the agonist muscle is contracted, which causes the antagonist muscle to relax and lengthen due to reciprocal inhibition. This allows for a deeper stretch of the antagonist without the risk of injury that might come from direct stretching. Overall, this approach enhances flexibility and range of motion effectively.
The triceps muscle is the primary muscle used in a cable extension.
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.
