Intrinsic feedback is the internal information received by an athlete based on the outcome of a particular movement or series of actions. Muscle memory gained through repetition is a common result of high levels of positive intrinsic feedback.
With any action or movement an athlete makes comes a reaction or result based either in performance or in kinaesthetic senses. For example, in track and field, a particular movement that produces a higher or a longer jump provides positive feedback to the athlete and is likely to be repeated. The athlete combines the intrinsic feedback with certain extrinsic elements to make up the whole of the feedback he receives from his performance and determine what actions should be repeated and what should be changed.
