The purpose of the present research was to determine whether EEG biofeedback training could improve archery performance as well as self-reported measures of concentration and self-confidence. Experienced pre-elite male (N = 16) and female (N = 8) archers were randomly assigned to one of three treatment conditions: (a) correct feedback (i.e., greater left hemisphere low frequency activity), (b) incorrect feedback (i.e., greater right hemisphere low frequency activity), and (c) no feedback control. The pretest and posttest consisted of 27 shots, with EEG data collected for the left and right temporal hemispheres (T3, T4). Feedback subjects were then given EEG biofeedback, while control subjects rested for 30 min. Analyses indicated that only the performance measure was significant. The correct feedback group significantly improved performance, while the incorrect feedback group showed a significant performance decrement from pre- to posttest (Ps less than 0.05). The control group showed no significant pre-post differences in performance. EEG analyses showed differences that were consistent with the training given to the incorrect, but not the correct, feedback group. Overall, the results provide some support for the use of known relationships between EEG and performance as an effective means of providing biofeedback to affect the performance of pre-elite archers.
本研究的目的是确定脑电图生物反馈训练是否能提高射箭成绩以及自我报告的注意力和自信心水平。经验丰富的准精英男性（N = 16）和女性（N = 8）射箭运动员被随机分配到三种治疗条件之一：（a）正确反馈（即左半球低频活动增强），（b）错误反馈（即右半球低频活动增强），以及（c）无反馈对照组。前测和后测包括27次射击，并收集左、右颞叶半球（T3、T4）的脑电图数据。然后对接受反馈的受试者进行脑电图生物反馈，而对照组休息30分钟。分析表明，只有成绩指标具有显著性。正确反馈组的成绩显著提高，而错误反馈组的成绩从前测到后测显著下降（P值小于0.05）。对照组的成绩在前测和后测之间没有显著差异。脑电图分析显示的差异与给予错误反馈组而非正确反馈组的训练一致。总体而言，研究结果为利用脑电图与成绩之间的已知关系作为提供生物反馈以影响准精英射箭运动员成绩的有效手段提供了一定支持。
