CSCS CSCS: Biomechanics of Resistance 3

Question 1

Which plane of motion is primarily involved in a lateral raise exercise?

Accepted Answer

Frontal (coronal) plane

Answer

The lateral raise moves the arm away from the body's midline in the frontal (coronal) plane through glenohumeral abduction.

Question 2

When calculating net joint torque during a squat, which of the following is NOT a required input?

Accepted Answer

Muscle fiber type percentage

Answer

Net joint torque analysis requires kinetic (force) and kinematic (position) data; muscle fiber type is a histological characteristic not needed for torque calculations.

Question 3

The center of pressure (COP) during a deadlift should ideally remain over which region of the foot?

Accepted Answer

Mid-foot to slightly anterior heel

Answer

A mid-foot COP position during the deadlift promotes balance and efficient force transfer through the kinetic chain from floor to barbell.

Question 4

Which muscle action occurs when a muscle exerts force while its length remains constant?

Accepted Answer

Isometric

Answer

An isometric muscle action produces force with no change in muscle length and therefore no joint movement.

Question 5

An athlete performs a plyometric depth jump. During the amortization phase, the primary biomechanical goal is to:

Accepted Answer

Rapidly transition from eccentric to concentric action

Answer

The amortization phase (ground contact) must be brief so that stored elastic energy is not dissipated as heat before the concentric propulsion phase begins.
