Think of stabilizers as the foundation from which your main muscles work. Even when the original reason for the sacroiliac stabilization is valid, often the human body overdoes it and tightens the musculature excessively and/or keeps it tight long after it needs to be, so the musculature becomes stuck in a chronic pattern of hypertonicity. They are the one joint stabilizers whose main role is to control direction-specific stress and strain. Anatomy of the Core The core is comprised of a complex system of muscle, ligament, and fascial layers that assist in providing spinal stability necessary for activities of daily living. Some muscles, such as stabilizers, consistently perform the same muscle role. Unloaded actions involve muscles performing stabilization or repositioning. Tendons attach muscle to bone. This gives your main muscles a solid base from which to generate force. These receptors are . A synergist muscle is a muscle which works in concert with another muscle to generate movement. The rotatores and intertransversarii muscles are highly rich in muscle spindles, 4.5 to 7.3 times more than the multifidus. The Anatomy of a Push Up.
