Probabilistic prognosis in sport kinetics
Journal Title: Antropomotoryka. Journal of Kinesiology and Exercise Sciences - Year 2011, Vol 21, Issue 55
Abstract
[b]Introduction.[/b] The efficacy of any human motor performance is limited by three factors: speed of movement, economy of motion and accuracy of movements. The authors hypothesize that all of them are strongly influenced by probabilistic prognosis (PP).[b]Aim of the study.[/b] The main task was proving the assumption that the human behavior is mainly of affective and not reactive nature. So the most important factor influencing the run of sensorimotor events is the PP rather and not the sheer reaction to extrinsic stimuli.[b]Material and methods.[/b] To demonstrate this, five experiments have been carried out. To the examinee the specific light stimuli were presented, to which the suitable choice response should be made. The measurements of reaction time enabled drawing conclusions about importance of the PP.[b]Results.[/b] In all the five experiments the crucial role of PP has been confirmed. As the movement is the only externally observed symptom of human’s brain activity, its observation enables building a model of information processing including intelligence, intuition and instinct. All these mechanisms the PP plays the crucial role. In sport, the PP enables clear differentiation between tactics and strategy. According to function of PP, the sport disciplines might be divided into groups three groups: of negligible function of PP (e.g. track-and-field sports), of important function of PP (e.g. combat sports and team games), and of decisive function of PP (e.g. chess, bridge).[b]Conclusions.[/b] The presented experiments confirmed the hypothesis that active behavior of a human is determined by PP rather and not by stimuli received from environment.
