Does training-intensity distribution affect parasympathetic activity in elite rowers?
Periodized low-intensity training may be beneficial for optimal training programming by preserving parasympathetic activity.
These data provide supportive rationale for the polarized model of training, showing that training phases with increased time spent at high intensity suppress parasympathetic activity, while low-intensity training preserves and increases it. As such, periodized low-intensity training may be beneficial for optimal training programming.
