The upper trapezius works with what muscle as a force couple to create upward rotation of the scapula?
Serratus anterior
Which of the following effects may occur if the amortization phase of a plyometric exercise is prolonged?
Stored energy will dissipate, and the unloading phase will be less powerful.
How should the amortization phase of the stretch-shortening cycle be described?
The transition from eccentric loading to concentric unloading
Which muscle functions as part of the global muscular system?
transverse abdominis
What term is used to describe muscle tension that is created without a change in muscle length and no visible movement of the joint?
Isometric
In order to optimally load muscle during the eccentric phase, the fitness professional should recommend which of the following?
Lower the weight more slowly to increase time under tension
Which muscle functions in a feed-forward mechanism in anticipation of limb movements?
Multifidus
What is a key mechanism involved in internal feedback?
Proprioception
Improved performance during a plyometric jump is dependent upon which of the following?
Rapid amortization phase
What is the scientific term that describes the nervous system's role in the contract/relax relationship between agonists and antagonists?
Reciprocal inhibition
Which plane of movement can be described as an imaginary line that bisects the body into right and left sides?
Sagittal
The anterior oblique subsystem includes which of the following muscle groups?
Adductor (inner) thigh muscles, obliques, and hip external rotators
What is the concept used to describe the action of muscles that have the ability to contract automatically in anticipation of movement?
Antagonist function
Movements that take place within a joint and are not visible to the human eye may be classified in what way?
Arthrokinematic
Which of the following statements would be accurate with regard to muscle force and velocity during an eccentric muscle action?
As the contraction velocity increases the ability to develop force also increases.
Pronation of the foot describes what multiplanar movements?
