NCCPT Applied Science and Kinesiology Questions and Answers

Question 1

A client is performing a standing dumbbell lateral raise. In which plane of motion is the primary movement occurring, and around which axis does this movement take place?

Accepted Answer

Frontal plane and anterior-posterior axis

Answer

Sagittal plane and mediolateral axis

Answer

Transverse plane and longitudinal axis

Answer

Sagittal plane and anterior-posterior axis

Question 2

During the downward phase of a squat, the quadriceps muscle group is lengthening while under tension to control the descent. What type of muscle action is being described?

Accepted Answer

Eccentric

Answer

Isometric

Answer

Concentric

Answer

Isokinetic

Question 3

A client is performing a box jump. To generate maximum power, they first perform a rapid countermovement by dipping down before exploding upwards. This sequence of an eccentric contraction followed immediately by a concentric contraction is known as what?

Accepted Answer

Stretch-shortening cycle (SSC)

Answer

Force-couple relationship

Answer

All-or-none principle

Answer

Sliding filament theory

Question 4

Which of the following best describes a force-couple relationship in the human body?

Accepted Answer

Two or more muscles pulling in different directions on a bone to produce a specific rotational movement.

Answer

A single muscle contracting to produce movement at a joint.

Answer

Two muscles on opposite sides of a joint contracting simultaneously to prevent movement.

Answer

A muscle group that works to slow down a movement through eccentric action.

Question 5

A personal trainer is explaining the biomechanics of a seated leg extension. The trainer notes that the knee joint acts as the fulcrum, the resistance is at the ankle where the pad rests, and the muscular force is applied by the quadriceps. This arrangement describes what class of lever?

Accepted Answer

Third-class lever

Answer

First-class lever

Answer

Second-class lever

Answer

Fourth-class lever

Question 6

When analyzing a client's gait, a trainer observes that their feet excessively turn outward. This movement primarily occurs in which plane of motion?

Accepted Answer

Transverse

Answer

Sagittal

Answer

Frontal

Answer

Coronal
