Introduction. Previous animal and human studies provided the evidence that
testosterone may affect ventricular repolarization by shortening of the QT
interval. Synthetic derivatives of testosterone, modified to enhance its
anabolic properties, are occasionally abused by some competitive athletes.
Objective. We assessed whether the QT interval duration could discriminate
androgenic anabolic steroids (AAS)-using strength athletes (SA) from
drug-free endurance athletes (EA), by comparing 25 formulas for QT interval
correction. Methods. We recruited 22 elite male athletes involved in
long-term strength or endurance training and 20 sedentary controls. All elite
