Answer to Question 1
Human skeletal muscle can be classied into three major ber types:
(1) slow-twitch, (2) intermediate, and (3) fast-twitch. Slow-twitch bers shorten slowly but are highly resistant to
fatigue. Fast-twitch bers shorten rapidly but fatigue rapidly. Intermediate bers possess a combination of the
characteristics of fast- and slow-twitch bers.
Answer to Question 2
Isotonic or dynamic contractions are contractions that result in movement of a body part. Isometric contractions
involve the development of force but result in no movement of body parts. Concentric contractions are isotonic
muscle contractions involving muscle shortening. In contrast, eccentric contractions (also called negative
contractions) are dened as isotonic contractions in which the muscle exerts force while lengthening.
