Question 1

Davis Law

Answer 1

States that “soft tissue molds along a line of stress”

Question 2

Altered Reciprocal Inhibition

Answer 2

overactive agonist muscle decreases neural drive to a functional
antagonist muscle

Question 3

Sliding filament theory

Answer 3

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

Question 4

Intrinsic motivation

Answer 4

you feel a sense of satisfaction, belonging

(ex: a grandma is happy because she can play with her grandkids due to exercising regularly)

Question 5

All-or-nothing principle

Answer 5

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

Question 6

Length-tension relationship

Answer 6

resting length if a muscle and the tension it can produce at this length, AKA relationship between actin & myosin (myosin is the larger myofilament)

Question 7

Principle of specificity

Answer 7

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