CERTIFIED STRENGTH AND CONDITIONING SPECIALIST (CSCS)
1. Which muscle group is the prime mover (agonist) for knee
extension?
A. Rectus femoris and the quadriceps femoris group ANSWER
B. Gastrocnemius
C. Gluteus maximus
D. Biceps femoris
The quadriceps femoris group extends the knee through the patellar tendon
and quadriceps tendon.
2. The sarcomere, the basic contractile unit of skeletal muscle, is
bounded by which structures?
A. M-lines
B. H-zones
C. A-bands
D. Z-lines ANSWER
A sarcomere is defined as the segment between two adjacent Z-lines.
3. Which muscle fiber type is the most fatigue-resistant?
A. Type IIx
B. Type IIa
C. Type IIb
D. Type I (slow-twitch oxidative) ANSWER
Page 1 of 48
, CSCS
Type I fibers have high mitochondrial and capillary density, favoring
oxidative metabolism and fatigue resistance.
4. The long head of the biceps brachii originates from which structure?
A. Radial tuberosity
B. Coracoid process
C. Supraglenoid tubercle of the scapula ANSWER
D. Olecranon process
The long head arises from the supraglenoid tubercle, crossing the shoulder
joint.
5. Which anatomical plane divides the body into anterior and posterior
sections?
A. Sagittal plane
B. Transverse plane
C. Frontal (coronal) plane ANSWER
D. Oblique plane
The frontal plane splits the body front-to-back; the sagittal plane splits it
left-right.
6. Which rotator cuff muscle initiates shoulder abduction and provides
external rotation?
A. Latissimus dorsi
B. Subscapularis
C. Teres major
D. Supraspinatus ANSWER
Supraspinatus initiates the first ~15 degrees of abduction and stabilizes the
humeral head.
7. Ankle plantar flexion is primarily produced by which muscles?
A. Peroneus longus
B. Extensor digitorum longus
C. Tibialis anterior
D. Gastrocnemius and soleus ANSWER
The gastrocnemius-soleus (triceps surae) complex inserts via the Achilles
tendon to produce plantar flexion.
8. During the downward (eccentric) phase of a bench press, what joint
action occurs at the glenohumeral joint?
Page 2 of 48
, CSCS
A. Horizontal adduction
B. Extension
C. Horizontal abduction ANSWER
D. Flexion
Lowering the bar moves the arm away from midline in the transverse plane,
which is horizontal abduction.
9. Which muscle is NOT part of the hamstring group?
A. Biceps femoris
B. Semimembranosus
C. Vastus lateralis ANSWER
D. Semitendinosus
Vastus lateralis is part of the quadriceps femoris, not the hamstrings.
10. Which connective tissue layer surrounds an entire muscle?
A. Perimysium
B. Tendon sheath
C. Endomysium
D. Epimysium ANSWER
Epimysium is the outermost connective tissue layer enclosing the whole
muscle belly.
11. Which muscle is the primary agonist for hip extension?
A. Gluteus medius
B. Gluteus maximus ANSWER
C. Iliopsoas
D. Sartorius
Gluteus maximus is the largest and most powerful hip extensor, especially
from a flexed position.
12. Which muscle acts as a key synergist/stabilizer of the knee during
the ascent phase of a squat?
A. Erector spinae
B. Deltoid
C. Vastus medialis ANSWER
D. Rectus abdominis
Vastus medialis helps control patellar tracking and knee stability during
squatting.

13. The anterior fibers of the deltoid are primarily responsible for
which motion?
A. Shoulder adduction
B. Scapular retraction
C. Shoulder extension
D. Shoulder flexion ANSWER
Anterior deltoid fibers flex and internally rotate the humerus.
14. Which bone is NOT part of the pelvic girdle?
A. Ilium
B. Femur ANSWER
C. Pubis
D. Ischium
The femur is the thigh bone; the ilium, ischium, and pubis fuse to form the
os coxae.
15. The latissimus dorsi's primary actions at the shoulder include:
A. Extension, adduction, and internal rotation ANSWER
B. Abduction and external rotation
C. Elbow flexion
D. Scapular elevation
The lat extends, adducts, and internally rotates the humerus, as in a pull-
up's downward pull.
16. Type IIx muscle fibers are best characterized by:
A. High oxidative capacity and fatigue resistance
B. High force production with rapid fatigue ANSWER
C. High mitochondrial density
D. Slow contraction velocity
Type IIx fibers rely on glycolytic metabolism, producing high force quickly
but fatiguing rapidly.
17. The transverse abdominis functions primarily to:
A. Extend the spine
B. Flex the trunk
C. Stabilize the spine by increasing intra-abdominal pressure ANSWER
D. Rotate the trunk
