The primary joint actions that occur during the squat include:Eccentric (lowering) Phase> Hip flexion> Knee flexion> Ankle dorsiflexion, Concentric (lifting) Phase> Hip extension> Knee extension> Ankle plantarflexion. When the leg is lifted away from the midline the gluteus medius fibers contract. Once any of these movement compensations have been observed, the squat is at a depth no longer suited for the individual. While there are numerous benefits to deadlifts, its vitally important to understand the fundamentals, and how the necessary antagonist and agonist muscle movements form the basis of all the exercises you complete. International Journal of Sports Medicine, 789-795.Padua DA, Bell DR, Clark MA.

When the muscles in the front of your body contract, the muscles in the back stretch and vice versa. The opposing muscle, which works to extend that muscle, is called the. As weve touched upon in our previous sections on both agonist muscles and antagonist muscles, the biceps and triceps function as both agonist and antagonist muscles. Fixator. Then take a look at agonistic muscles, the synergistic muscles and the stabilizers that make the squat . An antagonist muscle produces the exact opposite movement of the agonist muscle. Essentially, with each pair of agonist and antagonist muscles, one muscle will contract (the agonist muscle) and another will relax (the antagonist muscle) during each movement. 0 Save Share Copy and Edit Edit. > Stand up straight until hips and legs are fully extended. How Do Agonist and Antagonist Muscles Work Together?
