CSCS Periodization & Energy Systems 2

Question 1

Which energy system primarily fuels a 400-meter sprint race?

Accepted Answer

Slow glycolysis and oxidative system

Answer

A 400m sprint (~45–60 seconds) relies primarily on fast glycolysis with significant contribution from the oxidative system.

Question 2

What is the primary purpose of a hypertrophy phase in a periodized program?

Accepted Answer

Increase muscle cross-sectional area

Answer

The hypertrophy phase targets increased muscle cross-sectional area, building the structural foundation for subsequent strength and power phases.

Question 3

In undulating periodization, how frequently does the training stimulus change?

Accepted Answer

Every session or within the week

Answer

Daily undulating periodization (DUP) varies load and volume every session or across the training week, unlike linear models that change monthly.

Question 4

Which metabolic byproduct of anaerobic glycolysis is most associated with acute muscle fatigue?

Accepted Answer

Lactate and hydrogen ions

Answer

Hydrogen ion accumulation (associated with lactate production) lowers intracellular pH and impairs muscle contractile function during intense exercise.

Question 5

A mesocycle typically spans how long?

Accepted Answer

3–6 weeks

Answer

Mesocycles commonly last 3–6 weeks and represent a block of training with a specific goal such as hypertrophy, strength, or power.
