Synergist

Which concept should be used to describe the functioning of the serratus anterior as it assists the anterior deltoid during shoulder flexion?

Stored energy will dissipated, and the unloading phase will be less powerful.

Which of the following effects may occur if the amortization phase of a plyometric exercise is prolonged?

The Biceps brachia being active during extension

Which of the following examples describes a muscle that is functioning as an antagonist?

The biceps brachii being active during elbow extension

Which of the following examples describes muscle that is functioning as an antagonist?

Internal and external obliques functioning to create trunk rotation

Which of the following force couples is accurately linked to the movement created nay their combined action?

Brachioradialis

Which of the following muscles is primarily targeted when performing a biceps curl exercise with the thump up?

Place a small board under the heels

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?

As the contraction velocity increase the ability to develop force also increases.

Which of the following statements would be accurate with regard to muscle force and velocity during an eccentric muscle action?

Sagittal plane

Which plane of movement can be described as an imaginary line that bisects the body into right and left sides?

Isokinetic

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?

Muscular, nerveuse, and skeletal

Movement represents the integrated functioning of which three main body systems?

Eversion, dorsiflexion, and ankle abduction

Pronation of the foot describes what multiplanar movements?

Eccentric

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

How should the amortization phase of the stretching- shortening cycle be described?

The transition from eccentric loading to concentric loading

How should the amortization phase of the stretching-shortening cycle be described?

Lower the weight more slowly to increase time under tension

In order to optimally load muscle during the eccentric phase, the fitness professional should recommend which of the following?
