1) Health related fitness components vs skill related fitness component - ANSWER
Performance: Power, agility, skill, balance, Speed, reaction time
2) skeletal muscle - ANSWER -has striated, tubular, multinucleate fibers
-is usually attached to skeleton
-is voluntary
3) Smooth Muscle - ANSWER -has spindle-shaped non striated uninucleate fibers
-occurs in the walls of internal organs
-is involuntary
4) Muscle Architecture:
Multipennate? - ANSWER multipennate muscle, e.g., deltoid, rectis femoris, has
more than two columns of fiber converging on a tendon to form one muscle.
5) Muscle Architecture:
Quadrate? - ANSWER Quadrate (quadrilateral) muscles, e.g., rhomboids, are fl at,
four-sided non penate muscles.
6) Muscle Architecture:
Fan-shaped? - ANSWER Fan-shaped (radiate, triangular) muscles, e.g., pectoralis
major, gluteus medius, have fibers that radiate from a narrow point of attachment at
one end to a broader point of attachment at the opposite end.
,7) Muscle Architecture:
? - ANSWER Fusiform muscles, e.g., biceps brachii and brachioradialis, are
rounded, spindle-shaped muscles that taper at both ends.
8) Muscle Architecture:
unipennate? - ANSWER A unipennate muscle, e.g., tibialis posterior, has one
column of fibers that are arranged at an angle to the line of pull.
9) What type of muscle action produces the most force - ANSWER Eccentric
10) The difference between larger body size and smaller body size - ANSWER larger
body size = most force
11) give 3 examples of a descending exercise - ANSWER - Barbell row, pull-up, and
pull-down
Descending: A descending strength curve is one where the overall net force is greatest
initially but gradually decreases as the exercise progresses to its fi nal position
12) give 3 examples of a ascending exercise - ANSWER -Squat, bench press, and
shoulder press
An ascending strength curve is one where over-all net force is lowest initially but
gradually increases as the exercise progresses (examples include squat, bench press,
and shoulder press)
13) Type I Muscle Fiber - ANSWER Slow twitch, aerobic, best blood supply, slow to
fatigue (red)
14) Type IIa muscle fibers - ANSWER Fast-twitch, fatigue resistant, oxidative
15) Type IIb muscle fibers - ANSWER Fast twitch, quick bursts of energy, quick to
fatigue
, 16) Events at the Neuromuscular Junction:
Location?
When crossed by a neurotransmitter, it allows...? - ANSWER -the gap between
nerve and muscle
-action potential to reach the muscle
17) what chemical is released at neuromuscular junction - ANSWER -acetylcoa
18) Axons - ANSWER are long processes that are responsible for communicating with
target tissues.
19) Dendrites - ANSWER receive information from other neurons in the spinal cord.
20) Golgi tendon organs - ANSWER Receptors send information to the spinal cord
about the TENSION occurring at the muscle junction
21) Muscle spindles - ANSWER Feel the muscle length and cause stretch
22) Explain the processes involved in the sliding filament theory/sequence of events -
ANSWER -Actin attaches to myosin and then slides past myosin (causing
contraction)
-Sarcomere shortens in series
-Muscle fibers and muscle belly shortens
-Results in movement and force generation
23) Isometric - ANSWER No noticeable change in the length of the muscle
24) Concentric - ANSWER Positive component of muscle contraction (shortens)
25) Eccentric - ANSWER Negative component of muscle contraction (lengthens)
26) what muscular contraction creates the most force? - ANSWER Eccentric
