The Influence Of Sports Dance Appreciation On Female College Students’ Anxiety

[Objective]Anxiety is a kind of emotional experience mixed with tension,fear,worry and anxiety.Female college students in China are prone to anxiety.Although previous studies have shown that sports dance intervention is an effective way to treat anxiety,it is not clear whether watching sports dance videos can effectively improve the anxiety level of female college students and its brain mechanism.In view of this,this study adopted near-infrared brain imaging technology(fNIRS)to explore the influence of sports dance viewing on anxiety and its brain mechanism of female college students,and to provide experimental data for sports dance teaching research.[Methods]Research using eysenck personality questionnaire(EPQ)and self-evaluation of anxiety scale(SAS)were investigated,using E-prime material will induce anxiety and experimental video editing into experimental procedures,according to the special group of female college students sports special screening of sports dance,19 non-sports dance special group of female college students to study,22 were induced by anxiety after watching sports dance video,using fNIRS technology synchronous monitoring task during the prefrontal cortex related brain regions foxy-Hb concentration.[Results](1)After watching samba,the anxiety level of students in DanceSport group was significantly lower than that before watching samba(p<0.05).There was no significant difference in the anxiety level of non-DanceSport group before and after watching samba(p>0.05).(2)The concentration of Oxy-Hb in the "right ventrolateral prefrontal lobe"was higher in the DanceSport group than in the non-DanceSport group(p<0.01),(3)The anxiety level of students in DanceSport group and non-DanceSport group decreased significantly after watching rumba compared with before watching rumba(p<0.01)(4)The concentration of Qxy-Hb in the" left dorsolateral prefrontal lobe "was higher in the DanceSport group than in the non-DanceSport group when watching rumba(p<0.01)(5)There was no significant difference in anxiety level between introverted and extroverted students before and after watching samba(p>0.05).(6)The concentration of Oxy-Hb in the "left frontal pole area" and "right frontal pole area" in extroversion group were significantly higher than those in extroversion group(p<0.05).(7)The anxiety level of introverted and extroverted students decreased significantly after watching rumba compared with before watching rumba(p<0.05).(8)The concentrations of Oxy-Hb in the "left frontal pole area","right frontal pole area","left ventrolateral prefrontal lobe" and "right ventrolateral prefrontal lobe"in the extroversion group were higher than those in the introversion group(p<0.01).[Conclusion](1)Anxiety of female college students was significantly improved after watching sports dance.(2)When female college students watch sports dance,the concentration of Oxy-Hb in brain regions of "left frontal pole area","right frontal pole area","left ventrolateral prefrontal lobe","right ventrolateral prefrontal lobe" and "left dorsolateral prefrontal lobe "have significant diffcrences.Thc improvement of female college students’ anxiety mood was consistent with the significant difference of Oxy-Hb concentration in the corresponding brain area.(3)Female college students with different personality characteristics have different degrees of improvement in anxiety after watching sports dance,and there are differences in the concentration of Oxy-Hb in the brain.
