The authors of this paper have studied the characteristics of eye-movement of high school baseball players by applying advanced equipment in order to provide a theoretical guidance for the related researches and sports practice,.By using a 2×2×2 within-group design,the characteristics of eye-movement of high school baseball players and normal high school students were recorded and compared by iView Ⅹ HED eye-tracker when they watched the video of baseball pitching.The results show that there are significant differences between the two groups’ fixation frequency and length,fixation zones,etc.,while there is no significant difference for the influence of pitching styles on each index.Thus it is concluded after analysis:participants’ athletic skill level is the main factor that influences their frequency and length of fixations;the professional group’s fixation process is more comprehensive and specific and their tracking is more close;the professional group’s starting time of tracking the ball after it is released from pitcher’s hand is distinctly faster than the non-professional group;the biggest difference between the fixation zone of two groups is the fixation when nearby the pitching hand,which indicates there is a pre-decisional phase for the professional group participants when the ball is released.
