The Law of Accommodation / Variation (Periodization) suggests that a constant training stimulus will lead to what?

• A. Reduced Adaptation and Stalled Progress
• B. Increased Adaptation Indefinitely
• C. No Change in Adaptation
• D. Immediate Overtraining

Answer: (A)

When the same training stimulus is applied over and over, the body adapts to it and becomes more efficient at that specific demand. As a result, the stimulus no longer challenges the body enough to provoke new adaptations, so progress slows and eventually stalls. This is why variation and periodization are used—to continually disrupt the familiar demand and spark fresh adaptations. If you kept everything constant, gains would plateau rather than continue to grow. Increased adaptation indefinitely isn’t realistic because the body’s response to a fixed challenge diminishes over time. No change in adaptation isn’t accurate either, since you typically see some initial improvements that taper off without variation. Immediate overtraining isn’t a guaranteed outcome of a constant stimulus, though insufficient recovery with a steady load can contribute to overtraining if not managed.
