A Study On The Characteristics Of Emotional Attention Blink In Taekwondo Athletes Of Different Levels

Taekwondo,as one of the official events of the modern Olympic Games,is a sport that mainly uses hands and feet for fighting or confrontation.Taekwondo requires both participating athletes to complete offensive,defensive,and counterattacking actions at close range or even close to the body.In competitions,Taekwondo athletes need to adjust their tactical skills according to the opponent’s tactical characteristics and sports intentions.With a flexible and changeable movement pace,they can get active scoring opportunities in the competition.This places high demands on the attention of the athletes.The athletes need to obtain the opponent’s action information through visual channels,and make correct defensive or offensive actions through analysis in a very short period of time.Athletes may face a variety of emotional information stimuli in the arena,and these emotional stimuli will also have a great impact on the accuracy of the athlete’s processing of the sports information of themselves and their opponents in space and time on the arena.In this study,Taekwondo athletes of different sports levels were used as the research object,using a mixed experimental design of 2(neutral emotional stimuli,negative emotional stimuli)* 2(high level of exercise,low level if exercise),recruited from Tianjin University of Sport and Tianjin University of Technology.The61 subjects under the conditions of this study included 31 in the high-level exercise group and 30 in the low-level exercise group.Using self-compiled single-task and dual-task RSVP experimental paradigms to analyze the characteristics of Taekwondo athletes’ emotional attentional blink,the results of the study found that:(1)In the single-task RSVP experiment,athletes of different levels all showed attention blink.(2)In the single-task RSVP experiment and the dual-task RSVP experiment,high-level athletes are more accurate in identifying target stimuli than low-level athletes.(3)In the dual-task RSVP experiment,both high-level athletes and low-level athletes had different degrees of attentional blinks in the process of responding to different emotional types of interference stimuli.(4)In the dual-task RSVP experiment,exercise level has a main effect on emotional attentional blink.The duration of attention blink of high-level athletes is shorter,and the degree of attention blink is lighter than that of low-level athletes,but the lowest point of attention blink occurs earlier than low-level athletes.(5)In the dual-task RSVP experiment,the emotional stimulus type has a main effect in attentional blink.Compared with negative stimulation,the attentional blink caused by high-level athletes and low-level athletes is more significant than neutral stimulation.
