Specificity and Sensitivity of Visual Evoked Potentials [P.Sub.100] Latency to Different Events Exercise (Report‪)‬

1. INTRODUCTION Visual evoked potentials (VEPs) are a series of signals representing the responses of the visual occipital cortex to visual stimuli including flash and pattern stimuli, and can be used as one of the objective non-invasive neuro-physiological parameters in the assessment of the functions of visual organs, visual pathways and the optical central nervous system [1]. Previous studies have shown that both acute and regular/chronic exercise could affect VEPs independent from body temperature and other physiological parameters. But all the results are not consistent [2,3,4,5,6,7]. [P.sub.100] latency is the representative component of VEPs and the most commonly used index for its high, steady amplitude and slight intra- and inter-individual variability. In order to investigate the specificity and sensitivity of [P.sub.100] latency to different physical activities, we recorded the efficacy of an aerobic cycloergometric exercise, tennis training, aerobic Latin exercise and Baduanjin of Health Qigong training for 6 to 8 weeks [8].
