NASM Vocabulary Flashcards
Relative Flexibility
The bodys tendancy to take the path of least resistance.
Autogenic Inhibition
States that a prolonged golgi tendon stimulation inhibits muscle spindles of the same muscle.
Reciprocal Inhibition
When an agonist recieves a signal to contract, an inhibitory signal is sent to its antagonist muscle which lengthens.
Synergistic Dominance
When a synergist muscle takes over for an agonist muscle that exhibits a decrease in neural drive.
Precontemplation
Not thinking about working out (stage 1 of change)
Gluconeogenesis
Creation of new glucose via non carbohydrate substrates, such as protein.
Extrinsic Motivation
Reward / Recognition (Ex. Winning 1st place in a race, cash prize, trophy)
Agonist
Prime mover for a lift (Ex. Bench Press agonist is chest)
Heart Anatomy
SA Node (Pacemaker of the heart), Pulmonery Artery (CO2 airway AWAY from the heart), Atriums (hold blood)
140/90
Hypertension. Systolic/Diastolic
Peripheral Heart Action
Squats - Pushups (Upper - Lower body interval training)
OPT Model Acute Variables
Rest, Reps, Intensity, Tempo
Davis Law
States that soft tissue molds along a line of stress
Altered Reciprocal Inhibition
Overactive agonist muscle decreases neural drive to a functional antagonist muscle.
Sliding Filament Theory
Muscle contraction involving actin and myosin sliding past one another, shortening muscle during concentric muscle action
Intrinsic Motivation
A sense of satisfaction, belonging (Ex. A grandma is happy because she can play with her grandkids due to exercising)
All-or-nothing principal
Motor units can’t vary amount of force they generate, they either contract maximally or not at all.
Length-tension Relationship
Resting length of a muscle and the tension it can produce at this length a.k.a. relationship between actin and myosin (myosin is the larger filament)
Principal of Specificity
States that the body will adapt to specific demands that are placed on it.
Neuromuscular Specificity
Refers to speed of contraction and exercise selection.
Mechanical Specificity
Refers to weight and movement placed on the body.
Type I Muscle Fibers
Aerobic, Fat utilization, slow twitch (marathon runner)
Type II Muscle Fibers
Carbs, Fast Twitch (Sprinter)
Bio Energetics (Phosphogen)
High Intensity / Explosive with long recovery (when creatine is used)
Bioenergetics (Glycolysis)
Moderate Intensity
Bioenergetics (Oxidation)
Low intensity, short rest period
