Question 8

Estim produces greater strength gains than exercise alone w/ the same force contraction due to the type II fibers contracting before type I fibers

Answer 8

Specificity theory

Question 9

Combining estim with exercise does not cause greater strengthening gains than either intervention alone if the same force of contraction is produced

Answer 9

Overload principle

Question 10

NMES justification for mm re-ed (3)

Answer 10

1. increases neuron excitability
2. Provides sensory feedback
3. Activates inactive synapses

Question 11

Contracts type II agonist fibers to fatigue mm and relieve spasm

Answer 11

direct approach for mm spasms

Question 12

contracts type II antagonist fibers to fatigue mm and relieve spasm

Answer 12

indirect approach for mm spasms

Question 13

with estim ________ are activated first

Answer 13

fast twitch

Question 14

with physiological contractions _________ are activated first

Answer 14

slow twitch
