Which of the following solutions would allow an individual to achieve a greater depth during the lowering phase of the squat if ankle stiffness is the cause?
Place a small board under the heels
What is the scientific term that describes the nervous system's role in the contract/relax relationship between agonists and antagonists?
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
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
What type of muscle action would expend the highest amount of energy at a fixed resistance level over a comparable duration?
Concentric
Which type of exercise accommodates effort whereby the harder the individual pushes or pulls, the more resistance they feel, despite the movement speed remaining constant?
Isokinetic
Which subsystem is responsible for providing both frontal plane mobility and stabilization of the lumbo-pelvic-hip complex?
Lateral subsystem
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
Which of the following muscle groups work both eccentrically and concentrically in the sagittal plane during a squat?
Quadriceps
Improved performance during a plyometric jump is dependent upon which of the following?
Rapid amortization phase
The anterior oblique subsystem includes which of the following muscle groups?
Adductor (inner) thigh muscles, obliques, and hip external rotators
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.
Which of the following statements would be accurate with regard to muscle force and velocity during a concentric contraction?
As the velocity of the muscle action increases, its ability to produce force decreases.
Which of the following muscles is primarily targeted when performing a biceps curl exercise with the thumb up?
Brachioradialis
Which of the following benefits may occur as a result of exercises that comprise only eccentric muscle actions that are appropriately loaded?
Increased anabolic hormone stimulation
Which of the following force couples is accurately linked to the movement created by their combined action?
Internal and external obliques functioning to create trunk rotation
Which of the following examples describes a muscle that is functioning as an antagonist?
The biceps brachii being active during elbow extension
Performing a biceps curl with a dumbbell in the hand is an example of which type of lever?
Third class
What measurement is dependent upon the length of the lever arm and the angle between the force application and the lever arm?
Torque
During normal walking, the pelvis rotates in what plane to facilitate the necessary momentum for the swing phase?
Transverse
