I imagine most athletes have a simplistic mental model for their reduced resting heart rate. Something along this lines of: "training adaptation has built a mighty pumping machine whose facilities are barely taxed when I'm at rest". The adaptation described by this research changes the story significantly, to something more like: "in response to a long-running barrage of unserviceable 'beat faster' signals on the vagus nerve, an insensitivity to these signals developed, resulting in a cardiac system that may respond poorly to requests for increased blood volumes". That's a pretty major shift!
