What term describes organizing training into phases?

• A. Acceleration
• B. Specialization
• C. Calibration
• D. Periodization

Answer: (D)

Periodization is the approach of organizing training into phases to optimize performance over time. It divides a training plan into cycles—macrocycles, mesocycles, and microcycles—each with a specific focus such as building endurance, increasing strength, or sharpening for a competition. This sequencing allows for progressive overload, adequate recovery, and a planned peak for key events, while helping to prevent overtraining.

For example, a yearly plan might start with a base phase to build general aerobic fitness, move into a strength phase, then a power phase, and finally a peaking phase before a major event, followed by a recovery period. This structured progression is what helps athletes improve steadily and be at their best when it matters most.

Acceleration describes speeding up performance in a short window, not the overall plan. Specialization means focusing on a particular sport or skill, not organizing training over time. Calibration refers to adjusting measurements or loads to match a athlete’s capacity, not structuring phases.
