In undulating periodization, how are intensity and volume manipulated compared with linear models?

• A. Linear progresses load gradually within time.
• B. Undulating models vary intensity and volume more frequently within microcycles.
• C. Both linear and undulating keep intensity fixed.
• D. Undulating uses a fixed macrocycle with no microcycle variation.

Answer: (B)

The main idea here is how training stress is varied in undulating periodization. In undulating plans, intensity and volume flip-flop within short blocks, so you might have a high-intensity, low-volume session one day and a lower-intensity, higher-volume session soon after, sometimes even within the same microcycle. This frequent variation contrasts with linear models, where load generally increases in a steady, gradual way while volume tends to decrease over larger blocks. Saying that undulating models vary intensity and volume more frequently within microcycles captures the essence of the approach. In contrast, linear progression is about a slow, continuous increase in load or a structured decrease in volume over time, and the idea of a fixed macrocycle with no microcycle variation ignores the very pattern that defines undulating periodization.
