Section 1 — Functional Anatomy and Biomechanics
**Questions 1–33**
**Q1.** During a double-leg squat, an athlete’s right knee drifts inward into valgus. Which
plane and axis best describe the primary knee motion associated with this fault?
A. Sagittal plane; frontal axis
B. Frontal plane; sagittal axis
C. Transverse plane; vertical axis
D. Sagittal plane; vertical axis
**Correct answer: B.**
**Rationale:** Knee valgus is a frontal-plane motion combining abduction and internal
rotation at the knee. Frontal-plane motion occurs around an anteroposterior, or sagittal, axis. The
sagittal plane would describe flexion and extension, while the transverse plane would describe
rotation around a vertical axis.

**Q2.** A biceps curl is best classified as which type of lever system?
A. First-class lever
B. Second-class lever
C. Third-class lever
D. Fourth-class lever
**Correct answer: C.**
,Page 3 of 113
**Rationale:** In a biceps curl, the elbow joint acts as the fulcrum, the biceps brachii
supplies the effort between the fulcrum and the resistance, and the hand-held load is the
resistance. Because the effort is applied between the fulcrum and the resistance, this is a third-
class lever, the most common lever system in the human body.
---
**Q3.** During the lowering phase of a back squat, which muscle action is occurring at the knee
extensors?
A. Concentric
B. Isometric
C. Eccentric
D. Passive shortening
**Correct answer: C.**
**Rationale:** The knee extensors lengthen under tension while controlling knee flexion
during the descent, which is an eccentric action. Concentric action would occur during knee
extension in the ascent, while isometric action would involve no change in muscle length.
---
**Q4.** According to the length–tension relationship, a muscle produces the greatest active
tension when:
A. It is maximally shortened
B. It is maximally lengthened
C. Actin and myosin overlap optimally
D. There is no calcium available
, Page 4 of 113
**Correct answer: C.**
**Rationale:** Active tension depends on the number of cross-bridges that can form between
actin and myosin. Optimal overlap allows the greatest number of effective cross-bridges.
Excessive shortening causes overlap of thin filaments and reduced force, while excessive
lengthening reduces actin–myosin interaction.
---
**Q5.** Which statement best describes the force–velocity relationship for concentric muscle
actions?
A. Force increases as shortening velocity increases
B. Force decreases as shortening velocity increases
C. Force is unaffected by shortening velocity
D. Force increases only during eccentric actions
**Correct answer: B.**
**Rationale:** During concentric actions, force and velocity are inversely related: as the
muscle shortens faster, fewer cross-bridges remain attached at any moment, reducing force
capacity. This is why very heavy loads move slowly and very light loads can move quickly.
---
**Q6.** A coach is assessing the moment arm of a resistance exercise. The moment arm is
greatest when the line of action of the force is:
A. Parallel to the segment
B. Perpendicular to the segment
