A full-arc knee extension refers to the complete range of motion in which the knee joint moves from a fully flexed position to a fully extended position. This motion involves the quadriceps muscles contracting to straighten the leg, allowing for optimal knee function and stability. Achieving full-arc knee extension is important for activities like walking, running, and jumping, as it ensures proper alignment and mechanics of the lower limb. It's often a focus in rehabilitation and training to promote joint health and prevent injuries.
What else can I help you with?
What muscles are involved in knee extension?
The quadriceps muscles are primarily involved in knee extension.
What is the primary function of the knee extension muscle?
The primary function of the knee extension muscle is to straighten the leg by extending the knee joint.
Agonists in knee extension?
An agonist muscle is a muscle that plays a part in the extension of a muscle. The agonist muscles for a knee extension are the quadriceps and hamstrings.
What type of rotation occurs when you perform knee extension?
Knee extension is primarily a sagittal plane movement that involves extension of the knee joint, resulting in straightening of the leg. It does not involve any specific type of rotation.

What are the antagonist muscle used in knee extension?
The antagonists would be those muscles that cause knee flexion. Hamstrings (biceps femoris, semimembranosus, semitendonosis) are the primary knee flexors, and would thus be antagonists to knee extension.
What is a strength exercise?
knee extension
Which of these is a strength exercise?
Knee extension
Which type of of movement bends the knee and brings the lower leg backward?
Extension. Extension increases an angle, as in straightening a joint. During extension, the knee or elbow are straightened.
What is the prime mover for knee extension?
quadraceps
What is the synergist to knee extension?
iliopsoas
Which nerve innervates knee extension?
OBTURATOR
