Do varying training loads affect T-wave amplitude and heart rate variability in world-class athletes?
In elite athletes, increased training load simultaneously affects ventricular repolarization and heart rate variability, suggesting a shift in cardiac autonomic modulation that could be used to tailor training protocols.
Iellamo et al. (2004) studied this question.
