What happens when the deltoid contracts concentrically?
When the Deltoid contracts the humerus abducts.
When glute max contract concentrically which movement occurs at the hip?
When the gluteus maximus contracts concentrically, hip extension occurs. This means the thigh moves backward, bringing the leg into alignment with the body.
Does the triceps contract concentrically during the down phase of a push up?
No, the triceps do not contract concentrically during the down phase of a push-up. Instead, they are involved in an eccentric contraction as the elbows flex and the body lowers toward the ground. This eccentric action helps control the descent and stabilize the movement. During the upward phase, the triceps contract concentrically to extend the elbows.
What movement occurs when the subscapularis contracts concentrically?
When the subscapularis muscle contracts concentrically, it performs internal rotation of the shoulder joint. This movement involves rotating the arm inward toward the midline of the body.
What type of movement takes place at the hip if the glutes contract concentrically?
Hip extension
What is a reamer used to accomplish?
A reamer concentrically enlarges a hole in a thin-ish piece of material.
What connective tissue contains cells arranged concentrically around the nutrient canal?
Osseous Tissue
What movement occurs when the infraspinatus contracts concentrically?
When the infraspinatus muscle contracts concentrically, it primarily facilitates external rotation of the shoulder joint. This movement is crucial for various activities that involve lifting the arm away from the body or throwing motions. Additionally, the infraspinatus plays a role in stabilizing the shoulder by maintaining the position of the humeral head in the glenoid cavity during arm movements.
