Abstract


In the sports performance of athletes success mainly depends on its access to visual information. Volleyball athletes only do, watching in the proper position on the right time, in order to accurately predict the second pass pass direction and the type of pass. We designed two experiments using 3 (skill level) × 2 (attack type) × 2 (scenes video) mixed design, skill level and attack type is a group variable scene video group variable. Skill levels to three levels - athlete athletes group, an athlete group, two athletes group, n = 10, a total of 30 players. The two offensive type of storm (4 storm, the storm and the 6th after the 2nd attack) and fast-break (the 3rd fastball and back slip), scenes video for offensive video and defensive video two kinds. The anticipation reaction by studying volleyball athletes of varying skill levels the anticipation made to watch offensively and defensively video to find out the correct rate, gaze duration to monitor the number of times, looking at the difference between the flow diagram and saccade distance . The results show that: 1, there are obvious differences in visual search feature of different attack types under the conditions of the athlete, one and two volleyball athletes. Visual search characteristics of the athlete athletes are better than one and two athletes, an athlete should be better than two athletes. Visual search feature offensive video better than the visual search feature in defense video. 2, the level of skills in the reaction accuracy and reaction when showing a consistent trend, the higher the skill level, to predict the reaction and response accuracy as possible. The defensive video in motion contexts of reaction and response accuracy is better than the offensive video in the sports situation stimulated reaction and response accuracy. Athlete athletes with a relatively reasonable visual search mode, watching the shorter the time, watching the fewer times, watching the smaller the frequency, the greater the distance of the saccade, gaze the allocation and watching trajectory is more concise and focused. The defense video contexts this search mode is more obvious. Distribution of visual search, the athlete athletes mainly watching attack point and setter, one and two athletes in addition to looking at the offensive point and setter, will also monitor the loss on the block and the ball's trajectory.
