1. This type of muscle blends into tendinous insertions that attach to
bones, pulling them, which produces the desired movement.
a. skeletal muscle
b. swell muscle
c. cardiac muscle
d. smooth muscle
Answer: a. skeletal muscle
Rationale: Skeletal muscle is voluntary and attaches to bones via tendons
to produce movement. Cardiac muscle is found only in the heart, and
smooth muscle lines internal organs—neither attaches to bones to produce
skeletal movement.
2. Muscles are connected to bones by what?
a. ligaments
b. tendons
c. science is still investigating
d. motor units
Answer: b. tendons
,Rationale: Tendons are dense connective tissues that attach muscle to
bone. Ligaments attach bone to bone, and motor units are functional
groups of muscle fibers and their innervating motor neurons.
3. What type of muscle fibers are referred to as couch potato fibers?
a. IIy
b. IIa
c. Fascia
d. IIx
Answer: d. IIx
Rationale: Type IIx fibers are fast-twitch glycolytic fibers that fatigue
quickly and are often underutilized in sedentary individuals, hence the
colloquial term "couch potato fibers." Type IIa are fast-twitch oxidative
(more fatigue-resistant), and Type I are slow-twitch.
4. Bodybuilders practice "muscle confusion" because:
a. Not all motor units are activated in movement
b. to honor Joe Weider
c. to "grease the groove"
d. it reduces energy expenditure
Answer: a. not all motor units are activated in a movement
Rationale: The principle of muscle confusion—varying exercises, rep
ranges, and angles—ensures that different motor units are recruited and
, stimulated over time. The body adapts quickly; changing stimuli prevents
plateaus and promotes continued hypertrophy.
5. What factor does not induce muscle hypertrophy?
a. metabolic stress
b. mechanical tension
c. muscle damage
d. caloric restriction
Answer: d. caloric restriction
Rationale: Mechanical tension, metabolic stress, and muscle damage are
the three primary mechanisms driving hypertrophy. Caloric restriction is a
dietary strategy for fat loss; it does not directly stimulate muscle growth
and can actually hinder it if excessive.
6. What muscle fibers are recruited first in any given movement?
a. slow twitch
b. fast twitch
c. it depends on genetics
d. this is a contemporary debate in science
Answer: a. slow twitch
Rationale: According to the Henneman Size Principle, motor units are
recruited in order of size—smaller, slow-twitch (Type I) fibers are recruited
first for any given movement. Fast-twitch (Type II) fibers are only recruited
when higher force output is required.
