Key Term Flashcards
Relative Flexibility
the body’s tendency to take the path of least resistance
Autogenic Inhibition
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 agonist muscle which lengthens
Synergistic Dominance
when a synergist muscle takes over for an agonist muscle that exhibits a decrease in neural drive
Pre-contemplation
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 a prize from a race, trophy)
Agonist
prime mover for a lift
- Military Press: deltoid, synergist tricep, antagonist lats
- Bench Press: chest, synergist triceps, antagonist posterior deltoid
- Squats: quads, knee/ glutes hip, synergist hamstrings , antagonist psoas
Heart Anatomy: SA Node
pacemaker of the heart
Heart Anatomy: Pulmonary Artery
CO2 away from the heart
Heart Anatomy: Atriums
Hold blood
Heart Anatomy: 140/90 is…
hypertension (systolic/diastolic)
Heart Anatomy : PHA Exercise
Peripheral Heart Action
Squats to Push-Ups (upper –> lower body exercises)
OPT Model Acute Variables
rest, reps, intensity, tempo
Davis Law states…
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 the muscle during concentric muscle action
Intrinsic Motivation
you feel a sense of satisfaction, belonging
comes from within, to feel good
ex: to be healthy, its fun
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 of a muscle and the tension it can produce at this length
AKA: relationship between acting and myosin
(myosin is the larger filament)
Principle of Specificity
states that the body will adapt to specific demands that are placed on it
Neuromuscular Specificity refers to …
refers to speed of contraction and exercise selection
Mechanical Specificity refers to …
refers to weight and movement placed on the body
Type I vs Type II muscle fibers
1 = marathon runner (slow twitch), aerobic/fat utilization
2 = sprinter (fast twitch), carbohydrates
Bio Energetics: Phosphorylation
high intensity / explosive with long recovery (when creatine is used)
Bio Energetics: Glycolysis intensity…
middle (moderate intensity)
