Abstract:In the last years there is increasing interest in the study of the effects of physical activity on the cardiovascular control of athletes by heart period (HP) and QT interval (QT) variability analysis. However, the relation between HP and QT variability in athletes has been poorly investigated. Therefore, we aimed at estimate transfer function gain (TFG) to typify the relationship between HP and QT variability in athletes. We acquired electrocardiogram in 18 half-marathon runners while supine (REST) and durin… Show more
