目的：探讨运动所致的视觉诱发电位改变是否是由于体温改变所致。VEP改变是否与运动强度存在依从性。方法：采用NDI-200（海神号）神经电检诊仪记录受试者（n=8）进行功率车（Monark839E）增量运动（起始负荷为25W，递增负荷量为25w／挡，每挡运动10分钟，转数为50rpm）前（安静状态）、近无氧阈强度运动（心率为130b／min左右．,RPE值为13左右）后即刻、近无氧阚强度运动待体温恢复至安静状态后、近极量强度有氧运动（心率为180b／min左右、RPE值为18左右）后即刻、近极量强度有氧运动待体温恢复后的视觉诱发电位。结果：与安静状态相比，在近无氧阈强度运动后即刻，P100潜伏期即呈现极显著性缩短（P〈0．01），近无氧闭强度运动待体温恢复后仍保持显著缩短（P：0．059）；近极量强度有氧运动后即刻显著缩4R（P〈0．05），近极量强度有氧运动待体温恢复后仍然保持显著缩短（P〈0．05）。近无氧阈强度运动后即刻及近极量强度有氧运动后即刻P100潜伏期之间并无显著性差异（P〉0．05）。结论：P100潜伏期对近无氧阈强度及近极量强度有氧运动有一定的敏感性，运动是不依赖于体温改变而对VEPP100潜伏期产生影响的因素之一，运动对P100潜伏期的影响并不存在有强度依从性。

Objective： To investigate whether changes of visual evoked potentials （VEP） induced by exercises owe to the changes of body temperature, and whether changes of VEP depend on different exercises intensities？ Method： Eight subjects was conducted on an incremental exercise test using Monark 839E（ the load started at 25w and incremental load was 25w/grade, the test sustained 10 minutes each grade, the cadence was 50rpm）. The visual evoked potentials at Pz point were recorded and analyzed with Nerve Detection and Diagnosis Instrument NDI -200 （Poseidon） for all subjects respectively just before taking exercises （resting state）, immediately after the time close to the anaerobic threshold intensity exercises （HR reached about 130b/min, REP was about 13） , the moment the body temperature recovered fully after the time close to the anaerobic threshold intensity exercises, immediately after the time close to the near maximal intensity exercises （ HR reached about 180b/min, REP was about 18） and the moment the body temperature recovered fully after the near maximum intensity aerobic exercises. Result： Compared with the resting, there was an extremely significant decrease of P100 latency （ P 〈 0.01 ） immediately after close to the anaerobic threshold intensity exercises; P100 latency still kept shortening significantly while the body temperature recovered fully after the time close to the anaerobic threshold intensity exercises （P = 0.059） ; the latency of P100 decreased significantly after the time close to the near maximal intensity exercises and the time the body temperature recovered fully after the near maximum in- tensity aerobic exercises （P 〈 0. 05 ） , There were no significant differences of P100 latency between immediately after the time close to the anaerobic threshold intensity exercises and the moment immediately after the time close to the near maximal intensity aerobic exercises. Conclusion： There was some sensitivity for P100 latency on close to the anaerobic threshold intensity exercises and close to the near maximal intensity aerobic exercises. Exercise is one of the factors having effects on P100 latency which is independent of changes of body temperaturo, the effects of exercise on P100 latency don＇ t exist intensity compliance.
