ABSTRACT
The most important variables affecting learning and subsequent performance of a skill is feedback. Feedback involves sensory information resulting from a particular movement and one source of feedback is from the athletes own sensory channels known as intrinsic or inherent feedback. Extrinsic feedback can be delivered in two main forms: knowledge of results (KR) and knowledge of performance. It is the responsibility of the coach to observe and analyze the performance and combine the information with previous results and observances. Feedback during a skill will often interfere with the atheletes performance as the athletes attention is divided between the feedback source and the skill. It also appears that feedback immediately following or after performance may not be optimal. Interactive computer video analysis systems can collect and store information that can be replayed to the athlete and reviewed numerous times. This reduces observer bias and enables a visual image of the event to be collected.
