ACSM Corrective Exercise Specialist Flashcards

What is the primary goal of corrective exercise?

Answer: To identify and address movement dysfunction and muscle imbalances to restore optimal movement patterns

Corrective exercise aims to identify dysfunction, address underlying causes (tightness, weakness, poor motor control), and restore efficient movement patterns.

In the corrective exercise continuum, which phase comes immediately after foam rolling (self-myofascial release)?

Answer: Static or active isolated stretching to lengthen the target tissue

After SMR reduces tone in overactive tissue via autogenic inhibition, static or dynamic stretching further lengthens the target muscle.

Which muscle is most commonly identified as overactive/shortened in individuals with anterior pelvic tilt?

Answer: Iliopsoas

The iliopsoas (hip flexor) is typically overactive and shortened in anterior pelvic tilt, pulling the lumbar spine and pelvis into extension.

What does the Golgi tendon organ (GTO) response trigger when overstimulated?

Answer: Autogenic inhibition — a reflexive decrease in muscle tension

When stimulated by excessive tension, the GTO triggers autogenic inhibition, causing the muscle to relax — the mechanism exploited by foam rolling and static stretching.

Reciprocal inhibition in the context of corrective exercise means:

Answer: When an agonist muscle contracts, the antagonist is neurologically inhibited to allow smooth movement

Reciprocal inhibition is the neural mechanism by which activation of the agonist (prime mover) reflexively inhibits the antagonist to allow efficient movement.

Which postural deviation involves lateral curvature of the spine?

Answer: Scoliosis

Scoliosis is an abnormal lateral (sideways) curvature of the spine, often with vertebral rotation.

During a movement screen, a client shows knee valgus (knees cave inward) during a squat. Which muscle is most likely underactive?

Answer: Gluteus medius

Knee valgus during a squat most often indicates weakness in the gluteus medius, which is responsible for hip abduction and external rotation that controls knee alignment.

What is synergistic dominance in the context of muscle imbalance?

Answer: A secondary (synergist) muscle compensates for an inhibited primary mover, becoming dominant in the movement

Synergistic dominance occurs when a helper muscle takes over because the primary mover is inhibited, leading to compensatory movement patterns.

Which assessment tool is most commonly associated with identifying movement compensations in 7 fundamental patterns?

Answer: Functional Movement Screen (FMS)

The FMS evaluates 7 movement patterns and uses a scoring system to identify asymmetries and dysfunctions requiring corrective intervention.

Static stretching of an overactive/tight muscle should be held for a minimum of how long to produce meaningful length changes?

Answer: 20–30 seconds

ACSM and NASM recommend holding a static stretch for 20–30 seconds minimum to allow the GTO response and neuromuscular relaxation to produce length change.

Which of the following best describes 'length-tension relationship' in muscle function?

Answer: A muscle produces optimal force at a specific resting length; force production decreases when the muscle is too short or too stretched

The length-tension relationship shows that peak force production occurs at the muscle's optimal resting length; deviation in either direction reduces force output.

A client demonstrates an exaggerated forward lean of the trunk during an overhead squat. This compensation most commonly indicates overactivity in which muscles?

Answer: Soleus and hip flexors

Excessive forward lean in the overhead squat typically indicates tight soleus (limiting dorsiflexion) and hip flexors (pulling the torso forward), contributing to a forward trunk lean.

What is the purpose of 'activation' exercises in the corrective exercise continuum?

Answer: To strengthen underactive muscles that have been neurologically inhibited by overactive antagonists

Activation exercises target isolated, underactive muscles to restore neuromuscular function and correct agonist-antagonist imbalances.

The term 'altered reciprocal inhibition' in movement dysfunction means:

Answer: An overactive agonist causes excessive inhibition of its antagonist, resulting in functional weakness of the antagonist

Altered reciprocal inhibition occurs when chronic overactivity of a muscle creates excessive inhibition of the opposing muscle, causing it to appear weak even without structural damage.

Pes planus (flat feet) is most commonly associated with which compensatory movement patterns in the kinetic chain?

Answer: Overpronation, knee valgus, and hip internal rotation

Flat feet cause overpronation of the subtalar joint, which drives tibial internal rotation → knee valgus → hip internal rotation up the kinetic chain.

Which of the following describes 'neural inhibition' as a cause of muscle weakness in corrective exercise?

Answer: A muscle is inhibited by excessive signaling from an overactive antagonist, appearing weak without structural damage

Neural inhibition causes functional weakness through neurological suppression rather than structural damage; the muscle appears weak because it is not being properly recruited.

When performing an overhead squat assessment, arms falling forward most likely indicates which dysfunction?

Answer: Overactive latissimus dorsi and underactive lower trapezius/serratus anterior

Arms falling forward in the overhead squat suggests a tight lat (which internally rotates and depresses the shoulder) and insufficient lower trapezius/serratus anterior activation to maintain overhead shoulder position.

What is the purpose of integration exercises in the corrective exercise continuum?

Answer: To retrain full movement patterns incorporating the corrected muscles in functional, multi-joint activities

Integration exercises retrain whole-body movement patterns using the newly activated muscles within functional movement contexts relevant to daily life or sport.

Genu valgum (knock-knees) observed during a single-leg squat most likely indicates overactivity in which muscles?

Answer: TFL (tensor fascia latae) and hip adductors

TFL overactivity (a hip internal rotator/abductor) and hip adductor overactivity combine to pull the femur into internal rotation/adduction, causing the knee to collapse medially.

What does 'muscle synergy' mean in the context of human movement?

Answer: The coordinated activation of multiple muscles to produce efficient, smooth movement patterns

Muscle synergy refers to the nervous system's ability to coordinate multiple muscles as a functional unit to produce efficient, purposeful movement.
