摘要
目的:就大学生篮球运动员负荷递增时心电图的变化进行分析,为运动干预提供理论依据。方法:于2001/2003选择烟台师范学院女子篮球队队员12人,采用日本三导心电图机,记录运动员安静状态,比赛前,比赛后及训练负荷递增时的心电图。结果:3年中通过对12名队员的心电图追踪检查,共测安静时心电图95人次,均为有效心电图,不同训练强度下心电图196人次,有效心电图189人次,有效率为96%。①12名运动员平均心率为53.9次/min,最低心率46次/min;最高为67次/min,窦性心动过缓8人(60次/min以下者)占66.7%。此外,篮球运动员随运动年限的增加,心率有减慢的趋势。②心电图的变化与训练强度密切相关。当强度负荷递增时,心电图改变增加,递增越快心电图的异常发生率越高,共有7人,可达58%。当心电图有变化的同时,对其进行负荷实验均为不正常型。紧张性增高型3人(43%),紧张性不全性2人(29%),无力型2人(29%)。结论:心电图的变化可反映不同训练阶段的运动员的心血管系统的功能及训练程度。当运动负荷递增时,尤其是强度负荷递增时,心电图的变化增多,其次是当强度符合递增速度过快时,心电图的变化增加。
AIM： To analyze the variation of electrocardiograph （EEG） in college basketball players in order to provide evidence for motor intervention. METHODS： Twelve female players from Yantai Normal University were selected from 2001 to 2003 to record EEG at static state, before and after match, and during progressively increasing load exercise. RESULTS： A follow-up of EEG was performed in the 12 players within three years, and EEG was examined 95 times at static state with an efficient rate of 100%, and 196 times during different degree exercise with an efficient rate of 96%（189）. ① Among the 12 players, the highest heart rate was 67 beats per minute, the lowest was 46 beats per minutes and the average rate was 53.9 beats per minutes. There were 8 players of sinus bradycardia （below 60 beats per minutes） accounting for 66.7%. In addition, heart rate in the players had a slower tendency with the prolongation of exercise time.② Changes of EEG was closely associated with exercise loading. The harder the training was, the quicker the EEG changed; the faster the change happened, the more possible the abnormality was. Sometimes, it took up to 58% in seven players. There were 3 （43%） players of tonic increase, 2（29%） of tonic incompleteness, and 2 （29%） of asthenia. CONCLUSION： Changes of EEG can reflect the function of cardiovascular system and training degree of athletes at different stages of exercise. Along with the training loading, especially the intensity loading progressively increasing or increasing faster, the changes of EEG become faster.
