Assessment Practice

This image is of an athlete running "Running involves flexion and extension of both the hip and knee.

When the extends and flexes it requires movement of the muscles in pairs. The pairs required are the gluteous maximus and hip flexors.

For hip extension the prime mover or the against muscle is the gluteous maximus. When this contracts the hip flexors stretch/relax this is known as the antagonist.

For hip flexion the opposite is true. The hip will be stretched or relaxed while the gluteous maximus is contracting out. This is known as agonist.
