How the size or amount of an intervention relates to the size of its effect.
A dose-response relationship describes how outcomes change as the quantity of an exposure or intervention (e.g. training volume, load, drug dose) changes, ideally in a systematic and often monotonic way. In sports medicine and rehab, this concept underlies decisions about how much exercise, load, or treatment 'dose' is needed to produce a desired adaptation or effect, but the true shape of the curve (linear, plateauing, U-shaped) is frequently unclear or population-specific, so findings should be interpreted cautiously and not over-generalised beyond the studied dose range.
