优秀击剑运动员脑象图特征

采用脑象图技术(EEQG)研究优秀击剑运动员大脑处理信息的能力。结果表明,优秀击剑运动员大脑处理信息的能力与普通人相比,激活能力总值显著较高,提示优秀击剑运动员大脑处理信息的量更大,处理信息的方式更多;击剑运动员大脑处理信息的优势单脑区为左前脑和右后脑,左前—右后脑是优秀击剑运动员双侧脑的最佳匹配;男女运动员在大脑左颞区优秀图形的差异显著,提示女运动员比男运动员有更稳定的情绪,更高的内驱力,更强的逻辑记忆和理性思维能力;击剑运动员优势图形中的特征图形为内方型和隧道型,非优势图形中的特征图形为逃逸型和奇异型;脑象图的技术参数中,边缘系数反映大脑处理信息的耗能量,它与击剑运动员的竞技状态呈较高的负相关,即边缘系数越低,运动员在竞技比赛中的发挥越好;击剑运动员边缘系数优秀型占总人数的62.4%,一般型占总人数的37.6%,提示我国优秀击剑运动员大脑处理信息的效率很高。

EEGcharacteristics of el ite fencing athletes

EEQG was adopted to investigate the elite fencing athletes' brain ability of information processing.The results showed that the activation ability value of the elite fencing athletes' brain ability of information processing was much higher than that of the normal people,which meant the brain could deal with more information and have more methods of information processing.The superior unilateral brain regions of information processing were the left forebrain and right epencephalon,which were the best match of both-side brain.Female athlete' moods were more stable than the male athlete';besides,they were more active,having more powerful logic memory,and more rational thoughts.Among the parameter of EEQG,marginal modulus reflected the consumption of information processing which was related with the fencing athlete' athletic form.This,the lower the modulus was,the better was the athletic form.The fencing athlete with good marginal modulus was 62.4%,with the normal being 37.6%,which indicated that the efficiency of Chinese fencing athlete' brain ability of information processing was rather high.
