摘要
采用ND I-200(海神号)神经电检诊仪对体育系田径专项(n=76)和球类专项(n=49)学生以及普通系学生(n=50)的脑干听觉诱发电位进行了记录分析并进行了横向比较研究。结果表明:与普通系学生相比,田径专项学生BAEPⅢ波、Ⅴ波的潜伏期,Ⅰ-Ⅲ波、Ⅰ-Ⅴ波的峰间期显著延长(P<0.05);球类专项学生BAEPⅢ、Ⅳ、Ⅴ波的潜伏期,Ⅰ-Ⅲ波、Ⅰ-Ⅴ波的峰间期显著延长(P<0.05)。与田径专项学生相比,球类专项学生BAEPⅢ波的潜伏期显著延长(P<0.05)。田径和球类专项学生的听觉反应时较普通系学生显著缩短(P<0.05)。结论:球类或田径运动可使BAEPⅢ波和Ⅴ波的潜伏期及Ⅰ-Ⅲ波和Ⅰ-Ⅴ波的峰间期显著延长,说明长期的球类或田径运动可提高上橄榄体的信息加工处理能力,使上传至大脑的听觉信息更加准确、清晰,以便于大脑皮层对传入的听觉信号能更加及时、快捷地做出相应的反应,且球类运动的影响较田径运动更加明显。
By using the neural electricity tester of NDⅠ-200,the BAEP of the students of track and field （n= 76） and ball game majors （n= 49） and that of other majors （n=50） is recorded and analyzed and then a transversal comparison is also made. Compared with the students of other majors, the peak latencies of Ⅲ ,Ⅴ and the inter peak latencies of Ⅰ -Ⅲ , Ⅰ -Ⅴ of the students of track and field major are prolonged obviously （P〈0.05）,and the peak latencies of Ⅲ , Ⅳ , Ⅴ and the inter peak latencies of Ⅰ -Ⅲ , Ⅰ - Ⅴ of the students of ball game major are also prolonged obviously （P 〈 0. 05）. Compared with the students of track and field major,the peak latencies of BAEP Ⅲ for students of ball game major are prolonged obviously. However, the auditory reaction time of the students of both the track and field and ball game majors is shortened obviously （P〈0.05）. Therefore it is concluded that the sports of track and field and ball games can make BAEP Ⅲ,Ⅴ（PL） and Ⅰ -Ⅲ , Ⅰ -Ⅴ （IPL） prolonged obviously, which means long-term exercise of track and field and ball games can improve the information-processing ability of the superior olivary complex and make the auditory information input to the brain more accurate and clear so that the cerebral cortex can make corresponding reactions to the input auditory information timely and quickly. Moreover,the effect of ball games is more obvious than that of the sports of track and field.
