摘要
Aim of Study: In particular, in the quick ball and racket games a good dynamic seeing is required [12]. The afferent dynamic seeing occurs via the retiina which mediates the stimuli for efferent dynamic seeing [6, 12, 14]. The aim of this study was to examine the dynamic visual acuity of sportsmen from sports with different demands on their dynamic seeing (DS).
Methods: 19 sports students took part in the study. 10 subjects participated in coached team sports (group I) and 9 remaining performed individual sports (group II). The DS was assessed by means of the Dusseldorfer test for dynamic seeing of Wist [22] which was performed twice on one day.
Results: The DS of the two groups in the first study did not differ (right eye 95.7 +/- 10.6% in group I vs. 94.3 +/- 6.9% in group II and left eye 97.6 +/- 4.8% vs. 95.3 +/- 5.6%; p >= 0.05). Also the second study there was no different in DS for the two groups (right eye 98.3 +/- 2.6% vs. 93.8 +/- 8.0% and left eye 99.3 +/- 1.2% vs. 95.6 +/- 7.0%; p >= 0.05).
Discussion: Our hypothesis about a different DS in players of ball games compared with non-ball sport players could not be proved. It is to be critically noted that a generalization is not possible due to the small sample numbers. Because DS is a necessary precondition in ball games further studies should be concentrated on its trainability.
