Key result
Professional soccer training was associated with a significantly higher prevalence of ventricular late potentials on signal-averaged electrocardiogram compared to a sedentary lifestyle (35.4% vs 15.5%, OR 2.99).
Why the study?
Exercise-induced cardiac electrical remodeling is not well known in Asian athletes, prompting evaluation of the association between vigorous exercise and abnormal late potentials on signal-averaged electrocardiogram.
Does vigorous exercise (professional soccer training) increase the prevalence of abnormal ventricular late potentials on signal-averaged electrocardiogram in young adults compared to sedentary controls?
Population
48 Korean professional soccer players and 71 healthy sedentary controls
Comparison
Professional soccer players vs healthy sedentary controls
Design
Cross-sectional study

Professional soccer players exhibit a significantly higher prevalence of ventricular late potentials on signal-averaged ECG compared to sedentary controls, suggesting exercise-induced cardiac electrical remodeling.
Lee et al. (2021) conducted a cross-sectional in Athlete's heart (n=119). Professional soccer training vs. Healthy sedentary lifestyle was evaluated on Presence of ventricular late potentials on signal-averaged electrocardiogram (OR 2.99, 95% CI 1.25-7.17, p=0.014). Professional soccer training was associated with a significantly higher prevalence of ventricular late potentials on signal-averaged electrocardiogram compared to a sedentary lifestyle (35.4% vs 15.5%, OR 2.99).
