Electrophysiologic effects of physical exercise were investigated by comparing groups of individuals who engage in regular intensive physical exercise (12 + h/week) to control subjects (2 + h/week). Electroencephalographic (EEG) activity was recorded under eyes open/closed conditions to assess baseline differences between these groups. Spectral power was less for the exercise compared to the control group in the delta band, but greater in all other bands. Mean band frequency was higher for the exercise compared to controls in the delta, theta, and beta bands. Some differences in scalp distribution for power and frequency between the exercise and control groups also were found. The findings suggest that physical exercise substantially affects resting EEG. Theoretical mechanisms for these effects are discussed.
通过比较定期进行高强度体育锻炼（每周12小时以上）的个体组与对照组（每周2小时以上），研究了体育锻炼的电生理效应。在睁眼/闭眼条件下记录脑电图（EEG）活动，以评估这些组之间的基线差异。与对照组相比，锻炼组在δ波段的频谱功率较低，但在所有其他波段较高。锻炼组在δ、θ和β波段的平均波段频率高于对照组。还发现锻炼组和对照组之间在头皮功率和频率分布上存在一些差异。研究结果表明，体育锻炼会对静息脑电图产生实质性影响。讨论了这些效应的理论机制。
