What describes a mesocycle in training planning?

• A. Medium-term training block (weeks/months).
• B. Long-term training plan (usually a year).
• C. Short-term training plan (usually 1 week).
• D. A daily warm-up routine.

Answer: (A)

In periodized training, a mesocycle is a mid-term training block that lasts for weeks to months and is designed to achieve a specific training objective within that window. It sits between the longer macrocycle (often spanning a year or more) and the shorter microcycles (typically a week). So, a mesocycle might be a focused 6–12-week phase—say, building base endurance, increasing strength, or improving speed—with planned changes to volume and intensity to progress toward the goal.

This is why the description fits best: a medium-term block that you plan and complete within a broader yearly plan. In contrast, a year-long plan reflects a macrocycle, a one-week plan aligns with a microcycle, and a daily warm-up is not a training block at all but a routine part of each session.
