Research On Visual Searching Features Of The Different Levels Of Women Volleyball Athletes In Anticipation Task

Successful performance in interceptive tasks depends largely upon the acquisition of visual information about the approaching object. Volleyball players only look at the correct time in the right position to predict accurately the direction of the setter pass and the type of pass.In this study, I designed two experiments using 3 (skill levels)×2 (attack types)×2 (scene video) mixed design, including skill level and attack types are group variables, the scene is a group variable video. Three levels of skill-master athlete group, an athlete group, two athletes, each group has 10 members, a total of 30. Two types of power attack (4-bit power attack,2-bit power attack and 6-bit power attack) and quick attack (3-bit quick attack and quick spike from a backward short set), two scene video with the offensive and defensive video. By researching the volleyball players of different skill levels watched the offensive and defensive video and make anticipation to find the anticipation-making reaction time, accuracy, attention to duration, fixation times, look at traffic patterns and the difference between saccade distance. The results show that:1. Under the conditions of different attack types, master, first and second grade volleyball players'visual search features has significant differences. The master grade players' visual search features are better than the first and second grade players,and the first grade players'visual search features are also better than the second grade players.The visual search features in the offensive video campaign stimulation are better than these in the defensive video campaign stimulation.2. Skill levels in response to the accuracy and reaction time shows the consistent trend of movement, the higher the skill level, the better the reaction time and response accuracy. In the offensive video campaign stimulation reaction time and response accuracy is better than defensive video campaign stimulation reaction time and response accuracy.3. Master grade volleyball players adopt a relatively reasonable visual search pattern, the shorter fixation time, the less number of fixation, the smaller frequency, the smaller the distance between eyes dancing, and monitor the distribution of attention track is relatively simple and focus. Defensive situations video performance of this visual search pattern is more obvious.4. The distribution of visual search, master grade volleyball players mainly pay attention on the attack intersection and the setter, but first and second grade volleyball players in addition to monitoring the attack intersection and the setter, the loss will be watching the block and the ball trajectory.
