The essence of rest and recovery in training lies in the understanding that the training process functions as a system for managing adaptations. It involves exposing the athlete to specific stimuli that elicit physiological responses, followed by structured recovery periods that allow the body to adapt to those stimuli. Without adequate recovery, adaptation cannot occur (Bompa & Buzzichelli, 2019).

Adaptation and Fatigue: An athlete’s ability to adapt to the varying workloads imposed by training and competition is critical. Failure to adapt to these fluctuating demands can lead to excessive fatigue, functional overreaching, or even overtraining syndrome, ultimately hindering performance goals (Bompa & Buzzichelli, 2019).

Foundation of Periodization: The primary aim of training is to progressively and systematically increase the training stimulus (intensity, volume, and frequency) to drive superior adaptations and enhance performance. Optimal adaptations occur when training loads are rationally alternated and sufficient recovery is integrated between sessions. This cyclical alternation of stress and recovery forms the cornerstone of periodization and underpins the principle of supercompensation (Bompa & Buzzichelli, 2019).

Supercompensation: Is considered the most fundamental concept in training theory. When properly applied, it ensures the restoration of energy stores and, most importantly, helps prevent the accumulation of critical fatigue levels that may lead to overtraining (Bompa & Buzzichelli, 2019).
