Research Abstract	1.Research results(1992) (1)The influence of endurance and progressive exercise on the somatosensory evoked potentials(SEPs) : The short latency components of SEPs showed a decrease in the latter of exercise and recovery. This feature was clearly shown under the condition of high intensity exercise with high blood lactate accumulation. (2)The modulation of brain-stem auditory evoked potentials(BAEPs) during motor preparation : The BAEPs amplitudes during the foreperiod were lower than those obtained before warning stimulus under the condition of responding to the auditory stimulus. 2.Research results(1993) The influence of progressive exercise on the BAEPs and visual evoked potentials(VEPs) : The BAEP latencies showed a decrease under the condition of high intensity exercise and recovery. The VEPs latencies likewisely showed a decrease under the same condition. The amplitudes of only VEPs showed a increase during progressive exercise.
