What does the acronym said mean in relation to sports medicine?

In sports medicine, the acronym SAID stands for "Specific Adaptation to Imposed Demands." It describes the principle that the body adapts specifically to the type and intensity of stress it experiences during training or rehabilitation. This means that to improve performance or recovery, the training must be tailored to the specific demands of the sport or activity. Understanding SAID helps athletes and trainers design effective training programs that promote optimal adaptation and performance.
