优秀运动员应激引起的消化系统躯体化症状与P300变化的相关性研究

Correlative Study between Digestive Symptoms of Somatization and P300 Changes of Athletes in the Stress-related Conditions

目的探讨优秀射击运动员应激状态下消化系统躯体化症状与ERP中P 300变化的关系。方法使用N euroScan 32Channel ERP System记录20名上海市优秀一线射击运动员应激前后P 300波幅、潜伏期,用SCL-90、功能性胃肠病罗马Ⅲ型诊断标准中消化系统躯体化症状条目对运动员测评,并进行比较分析。结果在8项消化系统躯体化症状中,反酸、恶心、呕吐、腹泻有显著性差异。有反酸症状的运动员应激后P 300潜伏期(425.83±36.82)高于无反酸症状运动员(377.14±32.32);有恶心症状的运动员应激后P 300波幅(11.34±4.31)低于无恶心症状运动员(16.81±4.97);有呕吐症状的运动员应激前(9.82±3.25)及应激后(7.55±1.35)P 300波幅均低于无恶心症状的运动员应激前(15.91±3.74)及应激后(16.05±4.52);有腹泻症状的运动员应激后P 300潜伏期(363.00±6.59)低于无腹泻症状的运动员(410.92±41.54)。结论消化系统躯体化症状与P 300变化具有相关性,提示不同消化系统躯体化症状发生机理与认知加工过程密切相关。

Objective To explore the relationship between digestive symptoms of somatization and changes in the P300 of the best shooter in state of stress.Methods Using NeuroScan 32 Channel ERP System recorded P300 amplitude and P300 latency of 20 first-line best shooters in Shanghai before and after stress analyzing athletes with different peptic digest of somatization symptoms and the number of somatization symptoms and SCL-90.Results In the eight-digestible somatization symptoms,acid regurgitation,nausea,vomiting and diarrhea showed significant differences.P300 latency of athletes who had acid regurgitation after stress（425.83±36.82）was higher than that without symptoms（377.14±32.32）.P300 amplitude of athletes with symptoms of nausea after stress（11.34±4.31） was lower than that of athletes without nausea（16.81±4.97）;P300 amplitude who had vomiting before stress（9.82±3.25） and after stress（7.55±1.35）,were lower than those of athletes without vomiting before（15.91±3.74） and after stress（16.05±4.52）;P300 latency of athletes who had diarrhea after stress（363.00±6.59） was lower than those of athletes without symptoms（410.92±41.54）.Conclusion There is a certain correction between different digestion of somatization symptoms and changes in cognitive processing of good shooters.
