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
What type of macronutrients and energy do Type II muscle fibers use?
Carbohydrates
Phosphagen
high intense / explosive with long recovery (when creatine is
used)
Glycolysis
middle (mod intensity)
Oxidation
low intense / short rest period.
What are the 6 States of Change
Precontemplation Contemplation Preparation Action Maintainance Termination
Precontemplation
not thinking about working out
Contemplation
thinking about working out within 6months
Preparation
exercising but not regularly
Action
exercising regularly but not for 6+ months
Maintenance
exercising regularly for 6+ months
Termination
never going back, not giving into temptations/old habits
What are the 6 planes of motion?
Sagittal, Frontal and Transverse.
Sagittal Plane of Motion
Divides the body into the left and right halves.
What are common actions of Sagittal plane of motion?
flexion and extension
What are common Sagittal exercises?
Squat, RDL, bicep curls, tricep extensions, chin up
Frontal plane of motion
Divides body into anterior (front) and posterior (back) halves.
What are the actions of the Frontal plane of motion?
abduction and adduction
What are common exercises of the Frontal Plane of Motion?
lat raises, jumping jacks, band walks
Transverse plane of motion
divides body into superior(above) & inferior(below) halves,
Actions of Transverse Plane of Motion
Rotation
Common Exercises of Transverse Plane of Motion
chest flies, reverse flies, curtsy lunge, cable rotation
BMI
Body Mass Index = height/weight
Normal/healthy BMI
18.5-24.9
Overweight BMI
25 - 29.9
