脑前额叶区经颅直流电刺激对纵跳能力影响的时效性研究
Timeliness study of effects of transcranial direct current stimulation in bilateral prefrontal region on counter movement jump
摘要
Abstract
Objective To explore the influence of transcranial direct current stimulation(tDCS)on the counter movement jump(CMJ)ability.Methods Twenty-one college students(ordinary college students group)and 17 college athletes(college athletes group)randomly received anodic tDCS(a-tDCS)and sham tDCS(s-tDCS)in prefrontal region under 2 mA for 20 min.After these two kinds of stimulation were completed,the CMJ data of these subjects were collected at 0,10,20,30,and 40 min.The two-way repeated-measures ANOVA(stimulation type×test time point)was adopted to analyze the changes in the jump height,acceleration,peak power,and peak vertical ground reaction force(vGRF).Results There were significantly interactive effects between jump height and peak vGRF(stimulation type×test time point)in the college athletes group.The simple effects analysis revealed that the data at five different time points after a-tDCS in the college athletes group were significantly better than the baseline value and those after s-tDCS(P<0.05).There were significantly main effects on acceleration and peak power under the stimulation type among college athletes.There were significantly interactive effects on acceleration,peak power,peak vGRF(stimulation type×test time point)in the ordinary college students group.The simple effects analysis revealed that the data at five different time points after a-tDCS in the ordinary college students group were significantly better than the baseline value and those after s-tDCS(P<0.05).There was significantly main effect on jump height under the stimulation type among ordinary college students.Conclusion In the prefrontal area,a-tDCS can promote the improvement of multiple indicators in the CMJ process,and some indicators have a certain degree of sustainability.It is expected to consider a-tDCS as one of the methods to enhance the CMJ ability.关键词
