【摘要】：目的通过常规脑电监测八段锦训练前后不同性别在校大学生的脑电β1和β2频带功率谱在总体和空间(导联)的变化,分析和探究八段锦诱发的"心"效应的性别特征。方法选择在校大学生为受试者,根据性别分成男性组和女性组,均接受八段锦培训,采用NT9200系列脑电图仪分别在训练前后进行脑电监测,统计分析比较训练前后2组的脑电β1、β2频带绝对功率的差异。结果总体比较:训练前,女性组β1、β2频带的绝对功率均高于男性组(均P0.01);训练后,男性组在β1、β2频带的绝对功率高于训练前(均P0.01),女性组在β1、β2频带的绝对功率与训练前相比均无统计学差异(均P0.05),男性组和女性组在β1、β2频带的绝对功率之间无统计学差异(均P0.05)。空间(导联)比较:脑电地形图上训练前不同性别的β1、β2频带分布存在明显区别,训练后不同性别组在β1频带分布趋势一致,在β2频带分布上男性组呈全脑区同步增高的特征,女性组在大部分脑区呈现减低的趋势。左右脑功能区的协同情况:训练后不同性别组在β1和β2频带的左右半球对应大部分脑区的相关性皆升高或由不具有相关性变为相关。结论八段锦锻炼对不同性别均能够诱发"心"的效应,这种"心"效应存在"平衡"特性和性别特征,"调心"效应的性别特异性进一步提示八段锦可能具有将不同性别的心理活动趋于一致的特点。
[Abstract]:Objective to analyze and explore the gender characteristics of "heart" effect induced by Bazuanjin by routine EEG monitoring the changes of 尾 _ 1 and 尾 _ 2 band power spectrum of different genders of college students before and after training. Methods the college students were divided into male group and female group according to their sex. All of them were trained by Baduanjin. EEG was monitored before and after training by NT9200 series electroencephalograph. The difference of the absolute power of 尾 1 and 尾 2 bands between the two groups before and after training was analyzed statistically. Results: before training, the absolute power of 尾 1 and 尾 2 bands in female group was higher than that in male group (all P0.01), after training, the absolute power of 尾 1 and 尾 2 band in female group was higher than that in male group (P0.01). The absolute power of 尾 _ 1, 尾 _ 2 band in male group was higher than that before training (P0.01), the absolute power in 尾 _ 1 and 尾 _ 2 band in female group was not significantly different from that before training (P0.05), there was no statistical difference between male group and female group in absolute power of 尾 _ 1 and 尾 _ 2 band (P0.05). Spatial (lead) comparison: there were significant differences in the distribution of 尾 1 and 尾 2 bands between different genders before training on the EEG topographic map. After training, the distribution trend of 尾 1 band was the same in different sex groups, and the male group had the characteristics of increasing the whole brain area in the distribution of 尾 2 band. The female group showed a decreasing trend in most brain regions. Synergy of left and right brain functional areas: after training, the correlation of most brain regions in the left and right hemispheres of 尾 1 and 尾 2 bands was increased or changed from no correlation to correlation in different gender groups. Conclusion Baduanjin exercise can induce the effect of "heart" on both sexes. This "heart" effect has the characteristics of "balance" and "gender", and the gender specificity of "regulating the heart" further suggests that Baduanjin may have the characteristics of bringing together the psychological activities of different sexes.
