How is an isokinetic muscle contraction best described?

Reciprocal inhibition

What term is used to describe the concept of how the functioning of one body segment can impact other areas of the body?

Regional interdependence

What movement term is used to describe the concept of adducting the shoulder blades so that they become closer together?

Scapular retraction

The upper trapezius works with what muscle as a force couple to create upward rotation of the scapula?

Serratus anterior

During a squat, the lowering phase would be described as what type of muscle action?

Eccentric

The anterior oblique subsystem includes which of the following muscle groups?

Adductor (inner) thigh muscles, obliques, and hip external rotators

Movements that take place within a joint and are not visible to the human eye may be classified in what way?
