Study On Eye Movement Of Goalkeepers Defensive For Penalty Ball

In sports, athletes can make the right decision depends mainly on the acquisition of the method of visual information. Football goalkeeper only do it in the right place at the right time can be accurately predicted judgment to the direction of the ball. In the study, we use the experts-new research paradigm, takings professional football goalkeeper and8students as subject testing goalkeeper to defend the ball a penalty for the exercise scenario fragments, the eye movement of professional goal-keeper dynamic characteristics was made a experimental study to compare the two sets of goal-keeper results of eye movements to explore the goalkeeper the ball in the defensive penalty,theeye movement characteristics of the impact of the decision-making accuracy. The result showed that:For all the judgment of the professional group video of the mean value is less than the reaction time new groups had no reaction time of the mean value. And the average rate was significantly higher than the novice group is try the accuracy of averageIn watching the video and whether all two groups had no head, torso and the swinging leg, supporting foot, ball and in vitro this6place at time of the primary and secondary significantly different, professional group in the swinging leg, support and head at the feet of the mean value is greater than the time special group, and in the trunk, ball and in vitro parts of the time less than the professional group.In the process of judgment penalty direction, special test group and the special test group of eye movement characteristics are differences. Special group goalkeeper adopted more effective visual search method, gazing at the relative concentration, Watch orbit is clear, simple, and look at the allocation of time primary and secondary more apparent. The direction of the penalty decision is the main observation parts of the support of kickers feet and swinging leg. The judge, the two areas is the key observations. Sports skills levels and practice experience to do the right to make decision is crucial, sports skill level is high, the more practical experience, and the decision accuracy is higher.
