The key challenge in athlete's screening is the distinction between abnormal and normal which is hindered by the fact that the adaptation to sports activity in endurance athletes is different to that in power athletes. Especially cardiomyopathies provoke changes in ECG and echocardiography (echo) at an early stage when clinical symptoms are absent. ECG and echo data and their relationship to fitness peculiar to top handball players have never been described. We studied 291 male first league handball players (32 Olympians/47 national players) (25.3±4.4 years). Check up consisted of ECG, spiroergometry and echocardiography. None had T-wave inversions, 3.1% showed early repolarisation abnormalities in the precordial leads. Sokolow-Lyon voltage criterion for left ventricular hypertrophy was positive in 19.3%. Spiroergometry showed a maximum oxygen uptake (peakVO₂) of 50.3±7.7 ml/min/kg body weight. LVmass was increased in comparison to normal values. There was a correlation between peakVO₂ and LVindex (p<0.001, r=0.341), (LVmass/peak VO₂ p=0.053, r=0.125). A relationship between cardiac dimensions and peakVO₂ could not be confirmed. In professional handball players early repolarisation abnormalities were less frequent and LVmass was increased when compared with soccer players. The need for normal values for different types of sports is crucial to guarantee a proper evaluation of athletes.
运动员筛查的关键挑战是区分异常和正常，这受到以下事实的阻碍：耐力运动员对运动活动的适应不同于力量运动员。特别是在心肌病早期，心电图（ECG）和超声心动图（echo）出现变化时，没有临床症状。ECG 和 echo 数据及其与顶级手球运动员特有的健身之间的关系从未被描述过。我们研究了 291 名男性一线手球运动员（32 名奥运选手/47 名国家队选手）（25.3±4.4 岁）。检查包括心电图、心肺运动测试和超声心动图。没有人出现 T 波倒置，3.1%的心前导联出现早期复极异常。左心室肥厚的 Sokolow-Lyon 电压标准在 19.3%的人中呈阳性。心肺运动测试显示最大摄氧量（峰值 VO₂）为 50.3±7.7 ml/min/kg 体重。与正常数值相比，LVmass 增加。峰值 VO₂与 LVindex 之间存在相关性（p<0.001，r=0.341），（LVmass/peak VO₂ p=0.053，r=0.125）。无法证实心脏尺寸与峰值 VO₂之间存在关系。与足球运动员相比，职业手球运动员的早期复极异常较少，LVmass 增加。为不同类型的运动提供正常值是保证运动员得到适当评估的关键。
