Popis: Background: Clinical electrocardiographic (ECG) guidelines for athlete’s heart are based upon cross-sectional data. We aimed to longitudinally evaluate the influence of endurance training on the ECG and compare the prevalence of ECG abnormalities defined by contemporary criteria.\ud \ud Methods: A group of 66 training-naïve individuals completed a six-month training programme with resting ECGs and cardiopulmonary exercise tests performed at baseline, two and six months. Data were analysed using repeated measures analysis of variance and the prevalence of ECG abnormalities compared between proposed criteria.\ud \ud Results: Maximal oxygen consumption increased from 45.4 ± 7.1 to 50.3 ± 7.1 ml·kg−1·min−1 (p
