Term
Definition
Relative flexibility
the body’s tendency 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 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/recognition (ex: winning 1st place in a race, cash prize, trophy)
Agonist
Prime move for a lift
SA Node
pacemaker of the heart
pulmonary artery
CO2 AWAY from the heart
Atriums
hold blood
140/90 blood pressure
hypertension
blood pressure
systolic / diastolic
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 & myosin sliding past one another shortening muscle during concentric muscle action.
Intrinsic motivation
you feel a sense of satisfaction, belonging
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 vs Type II muscle fibers:
Sprinter = 2 (fast twitch) marathon runner = 1 (slow twitch). Type 1 = aerobic / fat utilization, Type 2 = carbs.
