Question 1

What is slow oxidative fibers?

Answer 1

Uses smallest fibers, most oxygen, maintain postural support

Question 2

What is fast oxidative fibers?

Answer 2

Uses medium fibers, lower oxygen, primary aerobic respiration

Question 3

What is fast glycolytic fibers?

Answer 3

Uses largest fibers, little oxygen, quickness and powerful

Question 4

What is muscle tension?

Answer 4

When a muscle is stimulated to contract

Question 5

What is latent period?

Answer 5

Time after stimulus but before contraction begins

Question 6

What is contraction period?

Answer 6

Time when tension is increasing

Question 7

What is relaxation period?

Answer 7

Time when tension is decreasing

Question 8

What is size principle?

Answer 8

Recruit smallest motor units then largest

Question 9

What is muscle tone?

Answer 9

Resting tension in a muscle and change continuously for no fatigued

Question 10

Fiber at resting length generates what?

Answer 10

Maximum contractile force

Question 11

What is isometric contraction?

Answer 11

Same length, same tone

Question 12

What is isotonic contraction?

Answer 12

Same tone, length changes

Question 13

What is concentric contraction?

Answer 13

Muscle shortens as it contracts

Question 14

What is eccentric contraction?

Answer 14

Muscle lengthens as it contracts
