When the leg is lifted away from the midline the gluteus medius fibers contract. An agonist is a muscle that is capable of increasing torque in the direction of a limb's movement and thus produce a concentric action. To contract, the triceps relaxes while the biceps contracts to lift the arm. Antagonist: The antagonist in a movement refers to the muscles that oppose the agonist. Your synergist(s) will actually be your hamstrings as the biceps femorislong head assists greatly in hip extension. Muscles: Quadriceps.

The Optimal Load for Maximal Power Production During Lower-Body Resistance Exercises: A Meta-Analysis. In other words, due to limited ankle mobility, the knees are not able to track over the toes in the sagittal plane, so motion is borrowed from another plane. Muscular tightness of the calf complex or joint restriction in the ankle itself are the primary causes of this movement compensation. They are the muscles at rest while the movement is being performed. It is a common and useful practice in clinical set up to assess the relative balance of opposing muscle groups around a joint by comparing strength ratios of agonist and antagonist muscle groups (Sapeda, 1990). An agonist usually contracts while the opposing antagonist relaxes. (LogOut/ Dumbbell Front Squat6. Lets explore some key examples. Muscles that work like this are called antagonistic pairs. Understanding the different muscles, and how each of these can have a huge impact, is crucial to creating a sustainable, effective routine.
