The Eidetic of Motor Action: Eidolon Maturity and Correctness Estimation

the aim of paper is to design an estimation methodology of motion eidolon maturity and correctness. Organization and research methods: to actual track and field coaches were proposed to draw skeletons (sticks models) of the ideal sprint running step. Skeleton was relied on three key frames: 1) the moment of repulsion completion; the moment when center of gravity above the supporting leg; 3) the moment of setting the leg. They used the Kinovea biomechanical software application. Coachers evaluated all skeletons rating them on a 10-point scale. Evaluation procedure was repeated after a month. Method of expert assessments was used for eidolon correctness estimations. The degree of eidolon maturity was estimated by similarity results first and second evaluations. Results: The paper revealed a different level of maturity and correctness of motion eidolons of coaches. We determined interdependence of these indicators. The correct eidolons are saved in the coaches’ memory long time. In another side, vice versa, the good eidetic memory conduces to a correctness of motion eidolon. Conclusion Gestalt-perception of motor action, the motion eidolon and eidetic memory are a triad of perceptual processes that occur during the evaluation of sports technique. The effectiveness and efficiency of qualitative biomechanical analysis depends on each component of this triad.
