Abstract

: Sexual characteristics in brain neurophysiological activity are a significant area of research in cognitive neuroscience. As a sport that involves minimal physical movement, shooters remain largely stationary during aiming, facilitating the collection of their neural activity compared to athletes in other sports. : To investigate the neural characteristics of novice shooters of different genders under competitive conditions. : Sixteen subjects participated in a shooting competition following four weeks of training. Electroencephalogram (EEG) data and behavioral data (shooting scores, aiming curves, and pressure curves) were recorded during the competition, and the power spectral density (PSD) and phase-locking value (PLV) network features were extracted to explore further the correlation between the shooting scores and neural activity. : In our sample, (1) there were no significant differences in shooting scores between males and females; (2) there were differences in PSD values across the theta, alpha, alpha-2, beta, and gamma frequency bands between males and females; and (3) there were differences in PLV network properties in the theta, alpha, beta, and gamma frequency bands between males and females. Correlation analysis revealed associations between shooting scores and neural activity in male and female novices. : The case study demonstrated that males and females exhibited different neural activity characteristics in the shooting competition, providing a foundation for further investigation into the sex differences in neural activity in shooting competition.

摘要

大脑神经生理活动中的性别特征是认知神经科学研究的一个重要领域。射击作为一项涉及极少身体运动的运动,射手在瞄准过程中基本保持静止,与其他运动项目的运动员相比,更便于收集他们的神经活动数据。

目的

研究不同性别的新手射手在竞争条件下的神经特征。

方法

16名受试者在经过四周训练后参加射击比赛。在比赛过程中记录脑电图(EEG)数据和行为数据(射击成绩、瞄准曲线和压力曲线),并提取功率谱密度(PSD)和锁相值(PLV)网络特征,以进一步探讨射击成绩与神经活动之间的相关性。

结果

在我们的样本中,(1)男性和女性的射击成绩没有显著差异;(2)男性和女性在θ、α、α-2、β和γ频段的PSD值存在差异;(3)男性和女性在θ、α、β和γ频段的PLV网络属性存在差异。相关性分析揭示了男性和女性新手射击成绩与神经活动之间的关联。

结论

该案例研究表明,男性和女性在射击比赛中表现出不同的神经活动特征,为进一步研究射击比赛中神经活动的性别差异奠定了基础。
