CSC Power Development and Plyometrics

Question 1

What is the primary energy system used during maximal plyometric exercises lasting less than 10 seconds?

Accepted Answer

ATP-PC (phosphagen) system

Answer

Oxidative phosphorylation

Answer

Glycolytic system

Answer

Beta-oxidation

Question 2

The stretch-shortening cycle (SSC) in plyometric training involves which sequence of muscle actions?

Accepted Answer

Eccentric → amortization → concentric

Answer

Concentric → isometric → eccentric

Answer

Isometric → eccentric → concentric

Answer

Concentric → eccentric → isometric

Question 3

Which of the following best defines reactive strength index (RSI)?

Accepted Answer

Jump height divided by ground contact time

Answer

Maximum force divided by time to peak force

Answer

Power output divided by body mass

Answer

Peak velocity divided by time to peak velocity

Question 4

When designing a plyometric program for a beginner athlete, which variable should be prioritized first?

Accepted Answer

Technique and landing mechanics

Answer

Intensity

Answer

Volume

Answer

Frequency

Question 5

Box jumps are classified as which type of plyometric exercise relative to depth jumps?

Accepted Answer

Moderate-intensity jump

Answer

High-intensity reactive drill

Answer

Depth jump variation

Answer

Bounding exercise

Question 6

A depth jump differs from a standard box jump primarily because depth jumps require the athlete to:

Accepted Answer

Immediately jump for maximum height upon ground contact

Answer

Land on a raised surface

Answer

Focus solely on landing mechanics

Answer

Use a bilateral stance only

Question 7

The amortization phase in plyometric training should be kept as short as possible primarily to:

Accepted Answer

Minimize elastic energy dissipation as heat

Answer

Increase time under tension for hypertrophy

Answer

Allow full muscle relaxation between actions

Answer

Reduce stress on connective tissue
