摘要
心电图的改变是运动员机体的机能状态和疲劳的表现,有明显的项目特征。对参加2000年全国男子拳击冠军赛的56名优秀拳击运动员的心电图进行了分析,结果显示:运动员组心电图异常者33例(不包括窦性心动过缓和左室高电压),占全部调查对象的58.93%,低于对照组;运动员组窦性心动过缓、左室高电压、不完全右树枝传导阻滞的发生率分别为87.5%、51.78%、7.14%,高于对照组的43.78%、18.34%、0.54%,两组间比较有非常显著性差异(P<0.005);拳击运动员的上述指标也高于冰雪运动员、举重运动员和游泳运动员[11]。拳击运动员的平均安静心率为(48.24±9.06)beat/min,低于对照组(P<0.005),而窦性心律不齐的发生率接近对照组,说明拳击运动员心血管功能强大的适应能力,这是训练有素的运动员心力储备良好的表现和运动水平提高的标志。
The changes of electrocardiogram represent the performance of body function and the level of the fatigue in athlete that there is the obvious characteristic of the sports events. This study carried on the analysis to the electrocardiogram of 56 excellent boxers who took part in the national boxing championship in 2000 and the result indicates that ECG of 33 boxers is abnormality except sinus bradycardia and left ventricle high voltage of in all, there is the incidence of 58.93 percent in the boxers and the rate is lower than the controlling group. The incidence of sinus bradycardia, left ventricle high voltage and incomplete right bundle branch block are 87.5 %, 51.78 % and 7.14 % in boxer group, it is higher than 43.78%, 18.34% and 0.54 % in controlling group. There is significant difference between two groups （P〈 0. 005）. The incidence of them in boxers is yet higher than that of athletes in winter events, lift weight and swimming. The resting heart rate of the boxers is （48.24±9.06） beat/min, it is significantly lower than the controlling group （P〈 0. 005）, and there is equality in the incidence of sinus arrhythmia between the groups. These show that there is the enormous adaptogenesis of cardiac - vessel function in the boxers and these changes are the good performance of cardiac reserve and the symbol increased exercise capacity.
