What does the SAID principle state?

• A. Specific Adaptation to Imposed Demands; training adaptations are specific to the imposed stimulus and goals
• B. Adaptations are random
• C. Any exercise yields the same adaptation
• D. Only high-intensity training yields adaptation

Answer: (A)

SAID, or Specific Adaptations to Imposed Demands, means that the body's training adaptations are specific to the type of stress you impose and the goals you’re aiming for. If you train with heavy loads and low reps, your nervous system and muscles adapt to produce more force, improving maximal strength. If you train for endurance, the muscles boost their oxidative capacity, mitochondrial density, and fatigue resistance. The same exercise won’t automatically improve all other capacities to the same extent; you get the adaptations most directly related to the demands you placed on the body. Because of that, different programs create different results. The idea isn’t that adaptations are random, that any exercise yields the same change, or that only high-intensity work matters.
