NASM Unit 3 Flashcards
During a Pushing assessment, what are the probable underactive muscles when a client’s shoulders elevate?
Middle/ lower trapezius
Name the imaginary bisector that divides the body into right and left halves.
Sagittal plane
After assessing a client’s Overhead Squat, which muscles should you have them strengthen?
Underactive muscles
During an Overhead Squat assessment, what are the probable underactive muscles when a client shows an excessive forward lean?
Anterior tibialis, gluteus maximus, erector spinae
After assessing a client’s Overhead Squat, which muscles should you have them foam roll and stretch?
Overactive muscles
Name 2 conditions in which Beta-blockers might be prescribed.
High blood pressure and arrhythmias
During an Overhead Squat assessment, what are the probable underactive muscles when a client’s low back arches?
Gluteus maximus, hamstring complex, intrinsic core stabilizers
What muscle action develops tension while lengthening and prevents resistance from accelerating in an uncontrolled manner?
Eccentric
During a Pushing assessment, what are the probable underactive muscles when a client’s head protrudes forward?
Deep cervical flexors
Name the assessment that measures lower extremity agility and neuromuscular control.
Shark Skill Test
Flexibility
The normal extensibility of all soft tissues that allows the full range of motion of a joint.
Extensibility
Capability to be elongated or stretched.
Dynamic Range of Motion
The combination of flexibility and the nervous system’s ability to control this range of motion efficiently.
Neuromuscular Efficiency
The ability of the neuromuscular system to allow agonists, antagonists, and stabilizers to work synergistically to produce, reduce, and dynamically stabilize the entire kinetic chain in all three planes of motion.
AKA - The muscles and nervous system working together to allow all muscles to move in all planes of motion together and proficiently.
Postural Distortion Patterns
Predictable patterns of muscle imbalances.
Relative Flexibility (altered movement patterns)
BAD -VERY BAD! Develops from poor flexibility.
The tendency of the body to seek the path of least resistance during functional movement patterns.
Creates bad habits.
Muscle Imbalance
Alteration of muscle length surrounding a joint.
Reciprocal Inhibition
The simultaneous contraction of one muscle and the relaxation of its antagonist to allow movement to take place.
“A naturally occurring phenomenon that allows movement to take place.”
EXAMPLE: To perform an elbow flexion during a biceps curl, the biceps brachii actively contracts while the triceps brachii (the antagonist muscle) relaxes to allow the movement to occur.
ANYTIME YOU ARE PERFORMING A REP, RECIPROCAL INHIBITION IS TAKING PLACE.
What does ‘HMS’ stand for?
Human Movement System (sometimes system is replaced with Science).
Altered Reciprocal Inhibition
The concept of muscle inhibition, caused by a tight agonist, which inhibits its functional antagonist.
MAKES EVERY REP MORE DIFFICULT IF NOT IMPOSSIBLE BECAUSE THE AGONIST IS TOO TIGHT.
Synergistic Dominance
The neuromuscular phenomenon that occurs when inappropriate muscles take over the function a weak or inhibited prime mover.
For example, if the psoas is tight, it leads to altered reciprocal inhibition of the gluteus maximus, which in turn results in increased force output of the synergists for hip extension (hamstring complex, adductor magnus) to compensate for the weakened glute max.
Arthrokinetic Dysfunction
Altered forces at the joint that result in abnormal muscular activity and impaired neuromuscular communication at the joint.
“When a joint is not working properly.”
