Which statement best describes periodization and the linear vs nonlinear models?

• A. Periodization is random scheduling of workouts without a plan.
• B. Linear progression involves random variation of load across time.
• C. Periodization organizes training into macro/meso/microcycles with planned variation, with linear and nonlinear (undulating) models describing how load changes.
• D. Periodization eliminates rest and recovery to maximize training days.

Answer: (C)

Periodization is the structured planning of training over time, so the year is divided into macrocycles, mesocycles, and microcycles, with planned variation in volume and intensity to optimize adaptations and peak performance. Within this framework, how load changes is described by different models: a linear model involves a steady, gradual increase in training stress across time, while a nonlinear (undulating) model introduces regular fluctuations in load to vary stimulus and manage fatigue. This combination—organized cycles plus either a steady progression or variable loading—best describes how training is organized and how intensity and volume can evolve. Random scheduling or eliminating rest would not fit this disciplined approach.
