A primary mover, also known as an agonist, is a muscle or group of muscles that is primarily responsible for initiating and executing a specific movement in the body. During physical activity, the primary mover contracts to generate the force needed for that movement, while other muscles may assist or stabilize the action. For example, in a bicep curl, the biceps brachii is the primary mover that flexes the elbow.
brachialis
A muscle that assists the primary mover or Agonist
primary mover
rectus fermris
The Gastrocnemius (calf muscle) is the primary mover. The Synergist (or assistor) muscle is the Soleus.
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
The synergist muscle performs the same movement as the primary mover. This often depends of the position of the joint.
The primary movement is called the Prime mover or Agonist
The vastus medialis is involved in leg extensions.
