The results showed that the activation ability value of the elite fencing athletes brain ability of infor oration 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 FFQG, marginal modulus reflected the consumption of information processing which was related with the fencing athlete athletic for m. T his, the low er the modulus w as, the better w as the athletic for m. T he fencing athlete with good marginal modulus was 6z.4%.w ith the nor oral being 3 }.6%.which indicated that the efficiency of Chinese fencing athlete brain ability of information processing was rather high.
