Understanding Antagonistic Muscle Pairs

The video explains how muscles work in antagonistic pairs to create movement. It uses examples like bending the elbow and kicking a football to illustrate the roles of agonist and antagonist muscles. The bicep and tricep are discussed in the context of elbow movement, while the quadriceps and hamstring are explained in relation to knee extension. The video concludes by directing viewers to interactive quizzes for further learning.

What is the role of the bicep when bending the elbow?

• It does not participate in the movement.

• It lengthens and relaxes.

• It acts as the agonist.

• It acts as the antagonist.

In the context of bending the elbow, what is the function of the tricep?

• It acts as the agonist.

• It lengthens and relaxes.

• It is the prime mover.

• It contracts and shortens.

Which muscle group is the agonist when extending the knee during a football kick?

• Triceps

• Quadriceps

• Biceps

• Hamstrings

During knee extension, what role do the hamstrings play?

• They act as the agonists.

• They contract and shorten.

• They are the prime movers.

• They lengthen and relax.
