Shorter sensory-motor reaction times have been reported in athletes compared with sedentary subjects. Previous results have shown significantly shorter visual evoked potentials (VEPs) latencies in a group of tennis players, but there was no difference between a group of rowers and control subjects. In the present study, the same groups were investigated in order to establish whether similar differences could be found in relation to brainstem auditory evoked potentials (BAEPs). Waves I to V latencies (Ls), interpeak latencies (IPLs) and wave amplitudes were measured. The results showed great differences related to gender. The I-III IPL was shorter in the females than in the males. Differences were also found in relation to physical activity. The most important feature was the significantly shorter III-V IPL observed in the rowers and in the tennis players of both genders compared with sedentary control subjects. In the males these differences were linked to training factors. Therefore, unlike VEPs which seemed to be linked to sports requiring high visual acuity, BAEPs seemed to be linked more widely to top-class physical activity and not to specific sensory aptitude. It was hypothesized that the shorter III-V IPL might be due to shorter synaptic transmission time in the superior olivary complex.
与久坐不动的人相比，运动员的感觉运动反应时间更短。先前的研究结果显示，一组网球运动员的视觉诱发电位（VEP）潜伏期明显更短，但一组赛艇运动员与对照组之间没有差异。在本研究中，对相同的几组人员进行了调查，以确定在脑干听觉诱发电位（BAEP）方面是否能发现类似的差异。测量了波I至波V的潜伏期（Ls）、峰间潜伏期（IPL）和波幅。结果显示与性别有很大关系。女性的I-III峰间潜伏期比男性短。在身体活动方面也发现了差异。最重要的特征是，与久坐不动的对照组相比，赛艇运动员和男女网球运动员的III-V峰间潜伏期明显更短。在男性中，这些差异与训练因素有关。因此，与似乎与需要高视力的运动相关的VEP不同，BAEP似乎更广泛地与顶级体育活动相关，而不是与特定的感觉能力相关。据推测，III-V峰间潜伏期较短可能是由于上橄榄复合体中突触传递时间较短。
