NASM Chapter 7

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
