Key Term

Question 1

Relative Flexibility

Answer 1

the body’s tendency to take the path of least resistance

Question 2

Autogenic Inhibition

Answer 2

prolonged Golgi tendon stimulation inhibits muscle spindles of the same muscle

Question 3

Reciprocal Inhibition

Answer 3

when an agonist receives a signal to contract an inhibitory signal is sent to its agonist muscle which lengthens

Question 4

Synergistic Dominance

Answer 4

when a synergist muscle takes over for an agonist muscle that exhibits a decrease in neural drive

Question 5

Pre-contemplation

Answer 5

not thinking about working out (Stage 1 of change)

Question 6

Gluconeogenesis

Answer 6

creation of new glucose via non carbohydrate substrates, such as protein

Question 7

Extrinsic Motivation

Answer 7

reward/recognition (ex: winning a prize from a race, trophy)

Question 8

Agonist

Answer 8

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

Answer 13

Squats to Push-Ups (upper –> lower body exercises)

Question 14

OPT Model Acute Variables

Answer 14

rest, reps, intensity, tempo

Question 15

Davis Law states…

Answer 15

States that soft tissue molds along a line of stress

Question 16

Altered Reciprocal Inhibition

Answer 16

overactive agonist muscle decreases neural drive to a functional antagonist muscle

Question 17

Sliding Filament Theory

Answer 17

muscle contraction involving actin and myosin sliding past one another shortening the muscle during concentric muscle action

Question 18

Intrinsic Motivation

Answer 18

you feel a sense of satisfaction, belonging

comes from within, to feel good
ex: to be healthy, its fun

Question 19

All-or-Nothing principle

Answer 19

motor units can’t vary amount of force they generate, they either contract maximally or not at all

Question 20

Length-tension Relationship

Answer 20

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)

Question 21

Principle of Specificity

Answer 21

states that the body will adapt to specific demands that are placed on it

Question 22

Neuromuscular Specificity refers to …

Answer 22

refers to speed of contraction and exercise selection

Question 23

Mechanical Specificity refers to …

Answer 23

refers to weight and movement placed on the body

Question 24
