Visual Search For College Student Male Volleyball Players Characteristics Of The Study

Purpose: This study to college students male volleyball players as the research object,using eye movement technology to observe dynamic smash video prediction behavior and eye movement indicators,compare different sports level(primary and secondary players)and different roles(setter,secondary attack,meet,main,free)college students male volleyball players in the visual search characteristics,in order to explore the visual search strategy and cognitive behavior of male volleyball players.Methods: Using the mixed design experiment method,25 experimental designs of five roles(setter,secondary attack,receiver,main attack and free man)at two sports levels(first and second level athletes)were designed.The spike video of volleyball players was used as the experimental material to explore the visual search strategies with eye movement and behavior indicators,and the experimental data were analyzed using the data analysis software.Results:(1)In the mean pupil diameter index,there were significant differences between the different roles of college student male volleyball players(P <0.01),and multiple comparisons found that the secondary attack group was significantly greater than that of receiver group,setter group and free person group;while the difference of second-level players was not significant(P>0.05),this effect was not observed;the difference of college men’s volleyball players of different sports levels was not significant(P>0.05),and the average pupil diameter of first-level volleyball players was higher than that of the second-level players.(2)In terms of average total fixation time,there was no significant difference between the different roles of the male volleyball players(P>0.05),and no significant difference was found in multiple comparisons;in the second-level players(P<0.05),the secondary attack group and setter group were significantly longer than the main attack group and free man group;the difference in the male volleyball players of different sports levels was not significantly different(P>0.05),and the average total fixation time of the male volleyball players was shorter than that of the second-level players.(3)In the average first sight time index,there are significant differences between different roles of players(P<0.01),multiple comparisons found that the free group was significantly smaller than the other roles;while the difference was not significant(P>0.05),this effect was not observed;the different grades were no different(P>0.05),the average first sight time is shorter than the second class.(4)In terms of average gaze number,there were significant differences between different roles of the volleyball players(P<0.05),and multiple comparisons found that the free group was significantly more than the receiving group and the sub-attack group were not significantly different(P>0.05),this effect was not observed;the volleyball players of different sports levels were significantly different(P<0.01),and the average gaze number of the players was significantly less than that of the second-level players.(5)In terms of average accuracy index,there were significant differences between the different roles of the first-level players(P<0.05),and it was found that the main attack group was significantly higher than the secondary attack group and the free group in the multiple comparisons;while the difference of second-level players was not significant(P>0.05),this effect was not observed;the players of different sports levels were significant(P<0.01),and the average accuracy rate of male volleyball players was significantly higher than that of the second-level players.(6)In terms of mean response index,the different roles of the male volleyball players were not different(P>0.05),and no significant difference was found in multiple comparisons;the second-level players(P<0.05),the main attack group was significantly higher than the free man group;different sports levels(P<0.01),and the average response of the first-level male volleyball players was significantly shorter than the secondary players.(7)The longer the average response of college male volleyball players,the longer the average fixation time,and the more the average fixation times.(8)The higher the average accuracy of college male volleyball players,the shorter the average fixation time.The longer the average response is,the more the average fixation times.Conclusions:(1)The average fixation points of the secondary attack group of college men’s volleyball first class athletes are small,the pupil diameter is large,and the reaction time is short.The athletes in this group have a stronger ability to quickly capture stimulus information during visual search.(2)The average total fixation time of the main attack group of college men’s volleyball secondary athletes is the shortest and the accuracy is the highest.This indicates that the attention concentration of the athletes in this group is better than that of other role groups,and their search ability for key stimulus information is stronger.(3)The ability of the first class men’s volleyball players of college students to select attention areas and processing methods of information sources is stronger than that of the second class men’s volleyball players of college students.(4)Correct rate: the main attack group is higher than the other four groups,suggesting that the athletes in this group have a stronger ability to process stimulus information and more professional experience.(5)In terms of reaction time,the free agent group is shorter than the other four groups,implying that the athletes in this group have stronger predictive ability.
