Top Vocab Words Flashcards
Reflective flexibility
the body’s tendency to take the path of least resistance.
Autogenic inhibition
states that a prolonged tendon stimulation inhibits muscle spindles of the same muscle.
Reciprocal inhibition
when an agonist receives 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/recignition (e.g: winning 1st place in a race, cash prize, trophy.
Agonist
Prime move for a lift
i.e.
Military Press (deltois; synergist triceps, antagonist; lats)
Bench Press (chest; synergist triceps; antagonist posterior deltoid)
Squats (quads, knee / glutes hip; synergist hamstrings; antagonist psoas
SA Node
Pacemaker of the heart.
Pulmonary Artery
Takes oxygenated blood away from the heart
Atriums
Hold blood
Stage 1 Hypertension
Blood Pressure of 140/90
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 & myosin sliding past one another shortening muscle during concentric muscle action.
Sliding filament theory-
muscle contraction involving actin & myosin sliding past one another
shortening muscle during concentric muscle action.
Intrinsic motivation
you feel a sense of satisfaction, belonging (ex: a grandma is happy because
she can play with her grandkids due to exercising regularly)
All-or-nothing principle
motor units can’t vary amount of force they generate, they either
contract maximally or not at all.
Length-tension relationship
resting length if a muscle and the tension it can produce at this
length, AKA relationship between actin & myosin (myosin is the larger myofilament)
Principle
of specificity
states that the body will adapt to specific demands that are placed on it.
Neuromuscular specificity
refers to speed of contraction & exercise selection.
Mechanical specificity
refers to weight & movement placed on the body.
Type I Muscle Fibers
Slow twitch muscle fibers. Think marathon runner.
What type of macronutrients and energy do Type I muscle fibers use?
Aerobic / Fat utilization
