采用ASL Eye Tracker 6000型眼动记录仪对不同水平排球运动员扣球动作图示视觉搜索注视点眼动特征进行实验研究。结果发现:(1)在起跳期段高水平运动员对躯干区注视点明显多于低水平运动员,在击球准备期段高水平运动员对上肢区注视点明显少于低水平运动员,在击球期段内高水平运动员对躯干区注视点数量明显多于低水平运动员,以上差异均非常显著;(2)高水平运动员在3个期段内对于上肢区注视次数呈均衡上升趋势,对躯干区注视点数量呈递减趋势;(3)高水平运动员无效注视点、回视点明显少于低水平运动员,差异非常显著;(4)高水平运动员判断正确率明显高于低水平运动员,差异非常显著。说明高水平运动员在长期的训练和比赛中,形成了稳定的、准确的、有效的视觉搜索动作信息的能力和快速加工信息及正确决策的能力。
An ASL Eye Tracker 6000 eye-tracking recorder was used to study the eye movement characteristics of the visual search fixation point in different levels of volleyball players. The results showed that: (1) In the period of take-off, high-level athletes had more fixation points than the low-level athletes in the trunk area. At the time of striking preparation, high-level athletes showed significantly less vigilance points than the lower- (2) High-level athletes showed a balanced upward trend in the number of upper extremity areas during 3 periods, while the number of high-level athletes in the trunk area was significantly higher than that of the low-level athletes The number of points showed a decreasing trend; (3) high-level athletes invalid fixation point, back point of view was significantly less than the low-level athletes, the difference was significant; (4) high-level athletes to determine the correct rate was significantly higher than the low-level athletes, the difference was significant. It shows that the high-level athletes in the long-term training and competition, the formation of a stable, accurate and effective visual search action information capabilities and rapid processing of information and the ability to make the right decisions.
