摘　　要：利用自行研制的跨颅脑电刺激仪,测试其对优秀举重运动员力量素质的影响,旨在为跨颅脑电刺激仪在举重项目中的应用提供实验依据.跨颅脑电刺激仪采用2.5mA低频电流,对陕西省举重队8名职业运动员颅脑部位进行5min的弱电刺激,观测刺激前后受试者握力、背力、摸高和立定跳远以及肘关节和膝关节60°/s、120°/s和180°/s 3种不同角速度屈伸肌等速肌力等指标变化,评价跨颅脑电刺激仪对举重运动员力量素质的影响.结果显示:举重运动员经跨颅脑电刺激仪刺激后,握力、背力、摸高和立定跳远等各项指标均有不同程度增加,肘关节和膝关节60°/s、180°/s和300°/s屈伸肌群峰力矩、屈伸肌群相对峰力矩等指标刺激后也均有不同程度增加,且部分指标增加显著.实验证实跨颅脑电刺激仪对举重运动员最大力量素质、速度力量素质及爆发力素质具有不同程度的促进作用.The research was to assess the effects of cross-brain electrical stimulation apparatus on strength performance of professional weight lifters. The strength-related indexes, such as grip strength,standing long jump,back strength,and elbow joint and knee joint in three degrees of 60 /s.120 /s and 180 /s joint extensor/flexor muscle,were tested in the eight professional weight lifters before and after stimulation by the cross-brain electrical stimulation apparatus with 2.5 mA intensity and 5rain times. The results show that the strength-related indexes, including their grip strength, back strength, jump high, standing long jump, as well as their elbow and knee joint extensor/flexor muscle strength, have different increase in the weight lifters after treatment by the cross-brain electrical stimulation. The results suggest that the cross-brain electrical stimulation apparatus could improve the maximum strength, speed strength quality and explosive force of the weight lifters, and would be used as an aid apparatus in weight lifting to improve the strength performance.
