摘要

Somatomatosensory evoked potentials (SEP) represents the bioelectric response generated by the stimulation of a peripheral nerve and are an electro-physiological method nervous system investigation. Our aim was to evaluate the parameters (latencies and inter-wave latencies intervals) of SEP waves in a group consisted of 18 professional male sportsmen, homogenous regarding age (average age is 20 years), height, weight and training regime, active for between 5 and 12 years exclusively in either handball or fencing (different stress degrees of the upper members) and to compare the resulted data in order to outline a neuro-physiological pattern particular to each sports. All the investigated sportsmen have been subjected to SEP tests and the responses obtained by stimulating the median nerve in the fist articulation (radial-carpal) bilaterally and successively were recorded and measured using the Nihon Kohden Neuropack MEB-9100 device. From the multitude of parameters provided by the analysis of recorded tracks, the values of SEP component waves latencies and those of inter-waves latency intervals were kept and statistically processed. The testing through SEP of performance sportsmen, practicing fencing and handball, has shown the existence at the level of the entire group of a higher values of the component waves latencies, obtained by stimulating the right median nerve, compared to those obtained by stimulating the left hand, although subjects were right handed, probably the effect of dominant member infraclinic lesions. The values of the Pearson correlation coefficient for the entire group, shows a positive left-right correlation for the wave latencies originated in the subcortical levels and specific cortical and a high left-right correlation for waves and interwave intervals, originated in the cortical non-specific areas, of association, a location more functionally and plastically changed by specific sports training. Key words: Professional sportsmen, Handball, Fencing, Somatosensory evoked potentials, Latencies, Interwave latency intervals, Association cortex, Neurophysiologic pattern.
