It is shown that the work capacity of operators performing continuously for 56 hours can be predicted on the basis of their EEG and HR. It is found that a drastic decrease of work capacity is preceded by a 20-30% increase of low-frequency (delta and theta) activity and a 15-40% decrease of high-frequency (alpha and beta) activity as well as by a simultaneous decrease of HR. These changes were revealed 1 to 4 hours before changes in the operator's work capacity.
结果表明，根据脑电图（EEG）和心率（HR）可以预测连续工作56小时的操作员的工作能力。研究发现，在工作能力急剧下降之前，低频（δ波和θ波）活动会增加20%-30%，高频（α波和β波）活动会减少15%-40%，同时心率也会下降。这些变化在操作员工作能力变化前1至4小时就已显现。
