不同专项运动员的关联负变化

Contingent negative variation of athletes for different sports

目前,国内外运动生理学领域中有关诱发脑电的研究尚属不多,而有关CNV的报导更是少见。本文通过对射击、短距离、球类等各专项组运动员CNV的波幅、面积、时程的比较,分析各组间的差异,阐明了以CNV作为有关专项运动员中枢神经系统的选材和脑功能评定的电生理学指标的可行性。

There are only a few studies of induced brain electricity made in the exercise physiological field at home and abroad up to now, while the reports on studies of contingent negative variation (CNV)are even rarer. Having made a comparision between athletes in such different specific groups as shooting,short-distance sports(running and swimming) ball game and so on for the amplitude, area and time internal of CNV, and a analysis of differences between the groups above, the present article has clarified the feasibility of taking CNV as the electrophysiological indices for the selection from central nervous system and assessment of the brain function of the athletes.
