目的：为了探讨快速减体重对青少年运动员认知功能的影响．方法：以少年体校8名散打（N＝4）和拳击（N＝4）项目男性运动员为受试对象，采取限制饮食、桑拿浴和适当运动的方法快速减体重，采用“基本认知能力测验（2．0版）”计算机软件（中科院心理所研制）测试受试者的基本认知能力．结果：受试者体重减至2．16％BW 时，认知能力测试值与实验前比较，仅发现心算效率明显减低11．27％（P ＜0．05）；而体重减至5．25％BW 时认知能力测试值与实验前比较，数字识别减低14．14％（P ＜0．05）、心算效率减低15．49％（P ＜0．05）、汉字旋转降低11．90％（P ＜0．05）、数字工作记忆减低19．06％（P ＜0．05）、图形再认降低6．91％（P ＞0．05）．结论：少年体校散打、拳击项目男运动员快速减体重达2％BW 即可显著减低其心算效率，而当减低体重达5％BW 以上则发现受试者数字识别、心算效率、汉字旋转及数字工作记忆测试值均明显下降．

Purpose:To investigate the effects of rapid weight loss on cognitive function in adolescent athletes.Method:Eight adolescent male subjects in free sparring(N=4)and boxing(N=4).During rapid weight loss,subjects intake diet in energy-restricted and water restriction and exercise as usual.The cog-nitive performance were tested by the software for basic perceptibility test(version 2.0)(Psychological Re-search Institute of CAS).Result:Compared with the experiment before,Mental efficiency decreased 11. 27%(P <0.05),when body weight reduced 2.16%BW(body weight).And when body weight reduced 5. 25%BW,Digital identification decreased 14.14% (P < 0.05),mental arithmetic efficiency decreased 15. 49% (P <0.05),Chinese characters rotation decreased 11.90% (P < 0.05),digit working memory de-creased 19.06% (P <0.05).Conclusion:Mental efficiency decreased significantly in adolescent male free sparring and boxing,when body weight reduced 2.16%BW.And when body weight reduced 5.25%BW, Digital identification,mental arithmetic efficiency,Chinese characters rotation and digit working memory decreased significantly.
